Damian Spangrud – April
Tell us about yourself.
I’m a carto geek and have been making varying degrees of visual junk for almost 3 decades. I’m interested in showing data in a way that makes people curious to learn more. I’ve been at Esri for 23 years and I’m the Director of Solutions (which means 2 things: 1. my team builds industry specific maps and apps to make it easier to use and 2. problems tend to find me). Visualizing space and time in static printed maps has limited how we tell stories about data for hundreds of years, and the move to fluid digital data means some long-standing cartographic rules may need to be bent…
Tell us the story behind your map (what inspired you to make it, what did you learn while making it, or any other aspects of the map or its creation you would like people to know).
I grew up in the Midwest and tornadoes were a fact of life. But while I knew I lived in Tornado Alley, I never had a good sense of what was the extent of that alley. And the maps that tried to define it seemed based on ideas and thoughts and not data. So I used data aggregation along with 3D to visualize the historical frequency of where tornados occurred. The raw data is a spaghetti mess of lines, but when aggregated into hexagons it becomes clear there is no narrow ‘Alley’, rather a large neighborhood. Looking at the data more you could see a pattern on when and where tornadoes were more likely. And using interactive time sliders you can also explore the general direction of tornado travel (which varies widely by region).
Tell us about the tools, data, etc., you used to make the map.
I used the historical tornado data (1950-2015) from NOAA. I used ArcGIS to aggregate the data into hexagons and do the 2D and 3D visualizations. The aggregations were based on count of major tornadoes (above a F3 on the Fujita-Pearson scale) inside the hexagons. I used the same color scale in 2D and 3D to allow for easier comparisons. But I felt both 2D and 3D added to the understanding of the pattern.
The 2017 GeoHipster calendar is available to order (NOTE: “Starting Month” defaults to the current month at the time of order. Remember to change to January 2017). 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 your shipping address to firstname.lastname@example.org).
Many thanks to Jonah Adkins and Ralph Straumann for the thought and effort they put into this year’s design. Also, special thanks to Mapbox for their continued support in helping to make the calendar possible.
Have a great holiday season!
Happy GIS Day! We couldn’t think of a better way for GeoHipster to celebrate GIS Day than to announce the selections for the 2017 GeoHipster calendar. Every year has yielded fantastic work and this year was no exception.
This was the first year we had a student track and we got two submissions. To help us work through the remaining submissions, we enlisted the help of three guest reviewers. This was a way to ensure that the process included fresh perspectives in addition to those of the members of the advisory board. So, we’d like to take time to thank Gretchen Peterson, Terence Stigers, and Brian Timoney for lending their professional and creative expertise to the review process.
Thanks also Jonah Adkins and Ralph Straumann, who acted as this year’s design team. I think you’ll be impressed when the calendar comes available. Speaking of that, we expect the calendar to be ready for purchase before Thanksgiving. Keep an eye out for an announcement!
So, without further delay, here are the cartographers whose work was selected for the 2017 GeoHipster calendar:
Michele Tobias – NASA Moon Trees
Mark Brown – Photorealistic Terrain Model from UAV Photogrammetry
Philip Steenkamp (student) – Netherlands Deltawerken
Damian Spangrud – Redefining Tornado Alley
Johann & Juernjakob Dugge – Raised Relief of Mount St. Helens
Ralph Straumann – Boston Summer Farmers’ Markets Walkability
Langdon Sanders – Sandy Springs, Georgia Sidewalk Network
Nathaniel Jeffrey – Melbourne, Australia Suburban Frontier
Alison DeGraff – Historic Hurricane Tracks
Alex Hersfeldt (student) – The Unified Republic of Tangland
Jan-Willem van Aalst – Amsterdam Canals from Open Data
Andrew Nelson – Visualization of Multi-Beam Bathymetric Survey Data
As you can see, the topics were wide-ranging; demonstrating the versatility of maps and imagination of cartographers. As for the maps themselves…you have to wait for your calendar to arrive in the mail!
Congratulations to all whose work was selected. Thanks to everyone who submitted. All will be featured on the GeoHipster web site.
Have a great GIS Day!
