Nyall Dawson
Nyall has been a core developer with the QGIS project since 2013. During this time he has contributed over 5,000 commits to the project, and today is one of the most active developers on the project. Nyall’s contributions to QGIS cover a wide range of areas – from improvements to the map rendering and symbology engines, enhancements to labeling and print layout functionality, right through to optimisations of the underlying spatial processing algorithms utilised by QGIS.

Nyall is the proprietor and lead developer at North Road Consulting, an Australian spatial development consultancy which predominantly utilises international co-funding and crowd-funding campaigns to finance development into open source GIS applications.

Nyall was interviewed for GeoHipster by Kurt Menke.

Q: Nyall Dawson, where are you located and what do you do?

A: I’m a geospatial developer, analyst, and (I’d like to think) a cartographer, and the director of North Road. I’m heavily involved in the QGIS project and am one of its current core developers, however, in practice my time is generally split about 60/40 between making software and making actual maps (i.e. being a GIS “user”). I also teach crime mapping and spatial analysis at Charles Sturt University. Geographically, I’m based on the Sunshine Coast in Eastern Australia (and yes, the name does describe it perfectly!). It’s as close as Australia gets to perfection – people  only leave here if work forces them to.

Q: You seem to be equally talented in programming and graphic design. What’s your background?

A: I’ve bounced between these two disciplines since high school, and it turns out that spatial analysis is a great mix of the two. While I originally studied mathematics at university, my first job after graduating was as a designer in the marketing department for an IT wholesaler. I was a horrible fit. This pushed me back towards the IT side of things, and I spent a number of years working on corporate networks. I stuck it out long enough to realise that while I enjoy working with software, I wanted to use it to actually make something  (instead of just making it work for someone else).

At the time my wife Maryanne and I decided that we needed a change, so we sold up everything we had, quit our jobs and spent 12 months backpacking around Latin America and Europe. I started collecting maps of places we’d visited, obsessively geotagging every photo we took, and filling in gaps in OpenStreetMap so that I could accurately track where we’d been. It was while hanging out in a bar in Argentina called “The Map Room” that Maryanne suggested I should look into studying maps when we got back to Australia. It’s a perfect profession for me – map making strikes a great balance between that desire to create something useful and pretty, while still being driven by mathematical algorithms and code.

Q: Maryanne is wise! Connect the dots for us. After returning from that year long adventure how did you learn about GIS and cartography, and when did you discover open source GIS and QGIS specifically?

A: So, back in Australia, I enrolled in a masters in “Geomatics”, which was a bit of a mix between every spatial discipline. A couple of early pracs involving surveying sites using steel tapes(!) quickly lead to me dropping every subject that wasn’t pure GIS or cartography. Towards the end of my masters I started working for Victoria Police, as a spatial analyst in their intelligence division. I loved the work – it involved a great variety of tricky spatial and statistical problems with the occasional need to make a pretty map. This is how I got started with QGIS — the commercial GIS package they used just had no capacity for making pretty maps, no matter what tricks you tried. I got sick of creating maps that I was embarrassed to show off so went hunting for alternatives which we could use (in other words… free alternatives. They had no software budget at all). This hunt lead to QGIS, and it wasn’t long before I was totally converted.

I’ve always been a bit of an open-source zealot anyway, so QGIS was a natural fit for me. To me open source just makes sense. I hate the feeling of being at the mercy of some distant software vendor to fix bugs and improve my daily workflow, so I’d much rather just have the ability to dig in and fix things myself. It’s a great model all round – even end users with no coding knowledge can still directly influence an open source project through sponsored features or fixes, and in the end everyone benefits from this.

Q: When I first met you, you were working for the Victoria Police. Why did you decide to launch North Road?

A: Well, as I started using QGIS at Victoria Police more and more, I started hacking away in my spare time to add improvements and fix any little bugs I’d hit during my day job. Doing this for an open-source project was one of the best learning experiences I’ve had. There’s always motivation to improve your work and make sure it’s in top form before opening up a pull request and knowing that it’s going to be visible to everyone and reviewed in public! Plus, you can always watch the changes which are flowing in from other developers and learning from their experience too. Luckily I had some great mentors early on (including fellow Australian geohipster Nathan Woodrow!) who always made themselves available for my constant questions and to refine my rough ideas. Over time the contributions I made became more ambitious as my confidence (and skills) grew, and I started getting queries from users who’d benefited from these contributions. I remember receiving my first email from a user asking “I saw you made this change recently to QGIS, how much would it cost to extend it a bit further and make it cover my requirements too?” – I had no idea what people would usually charge for work on open source, or indeed whether it was even considered “bad form” to charge for working on an open source project (Hint for all open source contributors: it’s not! Your time is valuable and you have no obligation to work for anyone for free!).

Things grew from there until I hit a critical point (when we had our second child), where I had to either make a decision to make this a full-time thing and quit the police work, or scale back the after hours work. I opted for the self-employment option since it meant I could wear teeshirts instead of a suit, listen to any music I wanted to all day, and stay up all night wondering if I’d made a terrible decision and would be broke and homeless in a month. And so North Road was launched.

Q: Walk us through a typical day being a QGIS developer and committer?

A: Well, right now we’re leading up to the launch of the next major version, QGIS 3.0. It’s going to be huge – there’s tons of new features and optimisations, and we’ve totally ripped out and rebuilt some of the older code areas and replaced them with brand new backends (composer, server, and processing). It also brings the change to Python 3 and Qt 5. So currently most of my daily development time is focused on getting 3.0 into top shape and squashing regressions before the final release. It’s a little stressful! Fortunately, the QGIS project enjoys the backing of numerous generous sponsors, which allows the QGIS organisation to directly employ developers to work on the trickier bugs in the lead up to a release. This allows me (among others) to focus our time on these fixes, and as a direct result the final release will be much more stable. (Hint for QGIS users – if you’ve ever wanted to see stabler releases, this is one way you can directly influence the quality of the final release… those sponsorship dollars and donations have a direct effect on the stability of QGIS!).

Following the release I’ll switch back to focusing on feature development – which means my days are filled with fundraising, writing proposals, and, when I’m lucky, coding new features.

Q: What are your favorite new features of QGIS 3?

A: That’s a huge question! The thing to keep in mind here is that QGIS 3.0 has been actively developed in parallel to the stable QGIS 2 releases for the last 2 years. So while the changelogs for the last couple of releases were substantial on their own, those were just for releases with the normal 4 month release cycle. You can start to extrapolate here and get an idea how long the changelog for 3.0 will be! I don’t think there’s any part of the code or interface which hasn’t been refined and improved in some way.

But in short, the features which make it difficult for me to go back to QGIS 2.18 are:

  • The improved label tools which allow you to just pick up and modify any label in your project, without needing to alter your layers in any way.
  • The reworked processing analysis framework and all the new and improved algorithms available in 3.0
  • and surprisingly, all the refinements to Geopackage handling which make them easy and convenient to work with. It’s actually enough to convert me from team shapefile!


Q: What is a QGIS feature you’d love to have time to work on but haven’t gotten to yet? What’s your wishlist?

A: Great question! My wishlist is HUGE, and grows every time I make a map. There’s two items which I’d say are top of my personal cartographic hit list right now:

  • Adding “distribute spacing” tools to the print layout designer. 3.0 adds a bunch of new “distribute item” actions which allow items themselves to be evenly spaced within a layout, but I want to be able to distribute the gaps between items instead. It’s a common functionality in desktop publishing and illustration applications which hasn’t yet found its way to QGIS.
  • Adding more automatic label placement options and refining the logic we already have. It’s good, but there’s always more we could do and finding ways to improve the automated placement benefits everyone – even if all you use QGIS for is visualising a bunch of shapefiles.

Fortunately, the QGIS user community has adopted a great attitude toward crowd-funding of features, and there’s been many funding campaigns which have allowed tweaks like these to happen in the past. I’ve already got a few campaigns lined up and ready to go for similar improvements following the release of 3.0!

Q: You mentioned that your time is generally split about 60/40 between making software and making actual maps. What types of projects do you work on when you’re not developing?

A: It’s a mix – these days it’s a whole range of analytical maps showing various statistical outputs right through to “simple” maps of various reference layers for government reports. Fortunately at the moment I’ve got a number of clients for whom high-quality visualisations are essential, so I get to spend time polishing maps and making outputs which I’m proud of. Surprisingly, they’re also almost exclusively print and static maps too. (On a slightly different topic, I personally suspect we’re going to see a swing back toward valuing static, non-interactive maps and data visualisations sometime. Everybody’s just so busy that maps and visualisations which can effectively and instantly communicate their message to a reader, without any data exploration, are likely to see a resurgence for projects where interactivity isn’t a key requirement!).

Q: I know you are a tabletop gamer. What are your favorite games these days? What else do you do for fun?

A: I’m all for co-operative, story-based games at the moment. The Arkham Horror Living Card Game is getting a lot of play (and accordingly, inspired the “Exploring the Depths of Madness Through QGIS symbology” talk I gave at the recent QGIS Australia meetup). TIME Stories and the Pandemic Legacy series are recent favorites too!

Incidentally, I love seeing board games with great cartography. There’s been quite a few games which have inspired me to try different mapping techniques. One personal favorite is the map for the GMT “Liberty or Death” game… that’s a beautiful map, which perfectly balances cartographic attention to detail with usability as a game set piece. It’s gorgeous (and incidentally, inspired a few QGIS symbology tweaks!), and I love that I can learn better map making just from gaming.

Apart from gaming, something I’ve recently rediscovered is how relaxing it is to just put on headphones and listen to an album without doing ANYTHING else. No dual-screening, no checking emails, no fixing QGIS bugs — just tuning out and listening!

Q: Do you consider yourself a geohipster? Why or why not?

A: Well, for a long time I was a holdout flag-carrying member of team shapefile, yet I’ve recently been won over by GeoPackage. I’m not sure if that makes me a geohipster or the opposite! (Shapefiles are retro-cool now, aren’t they?)

I *did* just move out to the country and to a place with our own vegetables and chickens, a farmer’s market next door, and an old avocado farm I can raid if I jump the back fence. I guess that makes me either a hipster or a hippy.

Q: Any words of wisdom or final thoughts you’d like to share with the GeoHipster community?

A: If I’m speaking philosophically, I think it’s crucial these days to have something “unique” you can bring to the profession. I don’t believe it’s enough to just be a “GIS specialist who knows XXX desktop GIS platform”. You’ve got to have something extra which differentiates you and helps you stand out from all the other GIS professionals. For example, you want to be “the GIS specialist who is a statistical wiz” or “the GIS specialist who can code and automate all those boring processes” or “the GIS specialist who can craft effective story-telling maps and visualisations”.

But if I’m speaking as a QGIS developer I’d say: mark down February 23rd in your diary,  download QGIS 3.0 and enjoy. It’s the magic unicorn fairy land of open source GIS™!

Anna Riddell on monitoring relative sea level change, accounting for the wiggle of the centre of the Earth

Anna Riddell
Anna Riddell
Anna works for Geoscience Australia as a Geodesist, but is currently doing a PhD at the University of Tasmania. Her research is focused on using Global Positioning System (GPS) data from Australian sites to derive a spatially-comprehensive vertical velocity field for the continent.

Anna was interviewed for GeoHipster by Alex Leith.

Q: You’re a Geodesist-hipster, right? So what is hip in the world of geodesy currently?

A: Geodesist-hipster doesn’t roll off the tongue as nicely as Geo-hipster, but we’ll stick with it for now.

There are so many exciting projects and new things popping up in geodesy, so these are just a few of them that I am excited for.

In Australia, it is predicted that by 2020 there will be in excess of 30 GNSS satellites visible at any one time. With the regular launch of new satellites, the major GNSS constellations are soon to reach maturity, creating a whole new world of multi-frequency, multi-constellation applications.

Other Earth observation missions are also being launched in the near future, one of which is the GRACE follow-on, which will enable the monitoring of changes in ice sheets and glaciers, the amount of water in large lakes and rivers and changes in sea level by observing changes in gravity.

In the realm of relativistic geodesy, there is some excitement around using optical lattice clocks for measuring elevation changes as well as the possibility to use the new clocks to redefine the SI unit of time and frequency (the second), effectively re-defining time… A bit closer to home we have the National Positioning Infrastructure capability and the Satellite Based Augmentation System trial, which is testing next-generation SBAS, a world first, in Australia.

Q: Australia has a new datum (GDA2020) that has just been released, and one day it might be dynamic. Do you think we can actually have one, considering the software challenges?

A: ‘Dynamic datums’ sound scary, but aren’t as daunting as they sound. The International Terrestrial Reference Frame (ITRF) could be considered as a datum that is continuously updated, where a new frame is realised every 4 years or so as new data becomes available and realignment is required. The new time-dependent Australian Terrestrial Reference Frame (ATRF), to be implemented in 2020, will be similar with periodic updates and realignment with the global frame. I wouldn’t say that it will be a major challenge for software, as the tools and resources needed are available and will be updated with each release. Noting that GDA2020 (current release) will still be available for users who do not need a time-dependent reference frame.

Q: Precession or nutation: which is your favourite?

A: Nutation! It’s more of a short term wiggle of the Earth’s spin axis due to the effect of the moon’s orbit, and more interesting to look at over short time spans (months to years).

Q: You studied at the University of Tasmania (same as me!); who was your favourite lecturer?! (You don’t have to answer this…)

A: Picking favourites is always dangerous (considering that I work with some of my lecturers now).

Christopher Watson (while teaching us least squares via first principles), for his entertaining idiosyncrasy of starting nearly every written sentence (on the white board) with ‘So,…’. I think the maximum count during one lecture was ~35 ‘So,…’ sentences.

Volker Janssen gets an honourable mention for the infiltration of AC/DC flavoured questions in some of our assessments.

Q: And after graduation, you joined Geoscience Australia, the largest geo-organisation in Australia, as part of their grad program, how was it?

A: The graduate program was an exciting year allowing me to experience the diverse range of earth-science related research undertaken to provide advice to the Australian Government. It was a fast-track introduction to the whole agency where we were encouraged to ‘step outside our comfort zone’ and explore areas that were not within our speciality/focus of our uni degrees. My 3 projects during the 12-month grad program were focused on:

  • Assessing the vulnerability of buildings to earthquake damage in Papua New Guinea;
  • Understanding the operation of Geoscience Australia’s geodetic networks, including the construction and installation of CORS and conducting a levelling survey from the Majuro tide gauge to the GNSS site in the Marshall Islands;
  • Classifying islands in the south Pacific on their vulnerability to climate change, specifically for groundwater storage and availability.

Q: GA are sponsoring your PhD, what is your elevator pitch for your thesis?

A: My PhD research is focused on looking at the vertical motion of the Australian tectonic plate, using permanent GPS sites all over the continent to track surface deformation. Part of my research is looking at reducing the error sources in precise GPS analysis, such as accounting for the wiggle of the centre of the Earth which presents as noise in the reference frame (ITRF2014). Having more accurate and precise estimates of vertical land motion in Australia will also enable more reliable observations of sea level change at tide gauge sites around the Australian coastline. Observations of sea level from tide gauges are made relative to the land that the tide gauge is attached to. Without knowledge of the vertical motion of the land (most commonly from GPS), our observations of sea level change can be biased. Relative sea level measurements are important for understanding local effects such as flooding and inundation, but the combination of sea level estimates from satellite altimetry and tide gauges requires knowledge of vertical land motion.

Q: What’s a surprising fact about plate tectonics that we don’t know yet?

A: There are around twelve tectonic plates that make up the surface of the Earth, but one plate (the Pacific plate) accounts for about 90% of all earthquakes, aka the ring of fire! This video is a great visualisation of earthquakes over a 15 year period. Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός “pertaining to building”) a.k.a Earth’s lego blocks?!

Q: You grew up in a small town, Wynyard, Tasmania, and then lived in our nation’s capital, Canberra. What’s different and what’s the same?

A: Although Canberra is our nation’s capital, it could still be considered as a rural city (not big and bustling like Sydney). My moving progression has been steady with a moderate change from rural Wynyard to Hobart and then a smaller change from Hobart to Canberra. I am not a big city person, so Canberra suits me well. It is hard to compare what it was like living in Wynyard to living in Canberra as they were such different stages of my life. When I was in Wynyard, I was living with my family and growing up (still doing that now too…). The move to, and then working in Canberra was the first step into the working world, and so the comparisons are hard to draw.

The biggest difference for me would be not being near the beach and seeing open water. Living on the NW coast of Tas meant that you were nearly always in sight of water (river, dam, ocean), or driving along the coast with the salty tang of the sea. In Canberra, Lake Burley Griffin doesn’t quite compare with its brown colouring and periodic blue-green algal blooms.

Canberra also has a much larger temperature differential than Wynyard with hot highs (> 35 degrees celcius) and freezing winter mornings (sub-zero). I do prefer the crisp, clear and sunny winter days of Canberra in comparison to the (mostly) dreary and grey Tassie winter!

Q: I found another interview with you that says you used to ride horses, do you still ride?

A: Moving to Hobart was the end of my competitive horse riding era, which mostly focused on Show Jumping and Eventing. During my undergrad I worked at a racing stable, which was a great way to keep riding and get my horsey fix without having a horse of my own. I still occasionally ride for pleasure, but no longer competitively. My horse, Flynn, is now retired and enjoying the good life in a paddock full of lush grass out the back of Sheffield.

Q: And what else do you do in your free time that isn’t GeoRelated?

A: I enjoy team sports, with football (soccer) taking up most of my Sundays during the season. We are just about to start our Summer Cup games as a pre-season warm-up before getting into the football season, running from March to September.

While in Tasmania I have a list of walks/experiences and adventures to undertake which I am slowly accomplishing on weekends that don’t involve football. (e.g. Tahune airwalk, Russell Falls, Cape Pillar, Cape Hauy, Maria Island, sampling all the wine and cheese…).

Toward Helping a Friend

A note from GeoHipster CEO Mike Dolbow

As I write this article, I am packed and prepared for three days “off the grid”, and honestly I could use a break from the daily news. I recognize that I have a tremendous privilege in being able to afford such a break, and that others are not so lucky. Nothing brought this fact to life as much as the recent news that Eni Entchev was deported…despite living in the U.S. for 25 of his 27 years.

Atanas with his son, Eni.

Eni is the son of Atanas Entchev, and sometimes we refer to Atanas as “the OG”…as in, “Original Geohipster”. While we may be using “OG” in jest, let’s face it – without Atanas, “Geohipster” might only be a Twitter account. It probably wouldn’t be a website with over 100 interviews published since it started almost 4 years ago. And it most definitely wouldn’t be the small independent business partnership it is today.

I certainly know I wouldn’t have been able to meet and/or interview so many amazing people these last few years without Atanas’ ideas, support, and generosity. And so when I learned that Eni’s family had set up a funding drive to pay for legal fees and living expenses, I knew I had to act. Like many of you – our amazing colleagues in the geospatial community – I donated from my personal funds. But also, with support from the GeoHipster Advisory Board, I’ve pledged 25% of the revenue from our 2018 GeoHipster Calendar sales.

So, this holiday season, as many of us take some time to celebrate our good fortune with loved ones, I hope you’ll consider either donating directly or buying a calendar to help reunite the Entchev family. Sure, hanging a unique calendar with 13 different pages of “map art” on your wall might make you the talk of the office. But knowing that in some small way you’ve also helped out a friend in need? To me, that’s what the geospatial community is all about.

Hanbyul Jo to GeoHipster: “Letters look like paintings when you don’t know the language”

Hanbyul Jo
Hanbyul Jo
Hanbyul Jo is a New York-based software engineer. She works at the open source mapping company Mapzen, where she develops tools to make web mapping more accessible.

Q: How did you get into mapping/GIS?

A: It was a lot of connecting dots. Mapzen, where I work currently, is where I got into mapping. Before working at Mapzen, I was at the intersection of visual arts and technology. I did some random things including installations and performance. I was not sure what I was doing at that time, so went to a 2 year master program covering technology and arts hoping to figure out what I can/want to do. (Now that I reflect, I was more lost in the program…it was fun wandering.) In the 2nd year of the program, I got into making physical objects in a parametric way with digital fabrication tools. For my thesis project, I wanted to fabricate the map of Brooklyn out of paper. The problem was that I did not have any clue about how to get the shape of Brooklyn at that time. Any concept of geo data at that time was foreign to me. Repeating some unfruitful tries, I started getting into this whole map thing. Looking back, my thesis project was a hot mess… However I didn’t fail! As I was leaving school, I had to start thinking about what the next step would be. As I narrowed down my interests, I thought that maps are a combination of many things I like, such as programming, cities, visuality, data. I looked up map companies that I could find in New York City, and here I am now.

Q:Tell us about your work with Mapzen. What’s your latest exciting project?

A: It is Mapzen.. we don’t put that much emphasis on zen 😉 (This was Hanbyul’s response to me originally capitalizing the “Z” –Ed.) I work as a front-end developer at Mapzen. It is my main job to develop tools that can make web mapping accessible for non-tech/geo-data savvy people. Since Mapzen is not a big company, I’m also responsible for some general front end work such helping other teams’ demos, UI work etc.

A new project that I am excited about is a tool for people to generate basemaps easily. Our cartography team is trying to offer basemaps in a modularized form so that they can be assembled as user needs, e.g.. making labels super dense with a yellow theme. This project just started and is still in a very early stage. If you are a cartographer in need of basemaps that are easily tweakable, we will reach out to you soon!

Q: Your Github account is pretty busy, and you have some cool maps hosted there, like this Seoul building explorer. Can you tell us more about this map and the inspiration behind it?

A: I sometimes think I would never have put anything on GitHub if it were not for my job. All the thoughts such as, ‘What if some people point out this is not the best practice? What if I am doing something totally ridiculous?’ really freaked me out at first. I anyway had to do it on daily basis because my current job requires as many things as possible to be open source, and then I finally got used to it.

Thanks for checking out Seoul Building Explorer. That was one of my full-stack projects that I got to every bit of what it takes to make a web map out of geospatial data. As a person who develops tools for cartographers, I often try to get my hands on the full workflow that cartographers should go through (from geospatial data to web map). When I was looking at how to deal with tiles, I noticed South Korea started making a lot of geospatial data open source. That was the basic foundation of Seoul Building Explorer. The map was iterated several times. The original data had a really wide range of building data such as materials, purposes of the buildings etc. It was so exciting that there is data openly available for me that I put all of them at once at first. Then I realized maps trying to tell everything often fail at telling anything. I started thinking about what I want to see in the map as a person who spent a lot of time in that city, and I also got some feedback from my coworkers with urban planning and design backgrounds. With some inspirations such as built:LA and the NYC PLUTO dataset map, Seoul Building Explorer got shaped as it is now.

Q: As far as I’m concerned, you delivered the coolest talk at JSGeo 2017 (among a pretty amazing slate of presenters), wowing the audience with pictures of 3D printed maps in materials like chocolate and ice! How on earth did you ever come up with that?

A: Did I? 😊

I am always jealous of people who grew up reading maps. Top down view maps were not part of my growing up. All buildings and landmarks were relatively positioned around me: the post office is next to the supermarket, my friend’s house is two units next to mine. Maybe this is because there was no street number system in Korea (where I grew up)? Even after mobile devices became prevalent, I didn’t often have to go somewhere that I was not familiar with, so didn’t really use maps that much.

After moving to NYC, maps became part of my life. I started looking at maps much more often than before as a newcomer of the city. While struggling to read the directions from it, my illiteracy of maps left me room to consider them as visual objects. Just like how letters look like paintings when you don’t know the language.

As I answered before, I first got interested in maps to fabricate with them. Working at Mapzen, I discovered many ways to convert/export maps into easily fabricatable forms (which was my js.geo talk topic. I gave a similar talk at NACIS 2017, you can check it out here). Also some of my great friends and classes at grad school taught me a great deal of craftsmanship and tips when dealing with real life materials. It really helped me to go through the whole fabrication process to know what to expect from real life materials.

Q: Geohipsters are often described as thinking outside the box, doing interesting things with maps, and contributing to open source projects. So, the evidence is stacking up: do you think you’re a geohipster?

A: I have really problem with labeling myself in my life. Hehe… but if I am a geohipster, why would I be in a geohipster box? 🙂

Q: When your chocolate maps become an international sensation, what words of wisdom will you deliver to your adoring fans?

A: Floss your teeth after eating chocolate.

2018 GeoHipster Calendar is Now Available

We’re pleased to announce that the 2018 GeoHipster calendar is available to order! Thanks to all who submitted maps for the calendar.

If your map made it into the calendar, we will send you a complimentary copy (please email pbr@geohipster.com for details).

Note: We’re switching print-on-demand vendors this year on a trial basis. The good news is the calendar costs less this year! The bad news? Previewing the content requires Flash. (Say it with us now, “ew”!) But trust us, the maps included are just as funky, unique, artful, and hipster-ish as in years past. If you’re really curious, Kurt Menke gave us a preview of his submission in November. Besides, what other calendar can you buy that has PostGIS Day marked on it?

Many thanks to Jonah Adkins for the cover design and image processing, and Bill Dollins for organizing the effort on behalf of the GeoHipster Advisory Board. Also, special thanks to our guest judges from recent years for helping us out!

Next year we aim to have a new way to propose map submissions for the 2019 calendar all year round. But in the meantime, get your 2018 calendar now, and pick up one for a friend (or your boss) while you’re at it. Have a great holiday season!
