Amy Smith is a Geospatial Data and Technology Specialist with Fehr & Peers in San Francisco. She’s had some great opportunities working with geographic information systems in a variety of fields, including environmental studies, satellite imagery analysis, water resources, and transportation planning. Amy currently spends her days working with an amazing group of people focused on improving transportation in our communities. In her free time she enjoys exploring the hills of San Francisco.
Q: A few years back we used to work together but I don’t actually remember how you got into GIS. You have a master’s in it right?
A: I do! I have a Master’s in Geography and Regional Studies. I got into GIS through a chance encounter with a geography professor whom I passed in a hallway on campus. Somehow we started talking about geography. I was undeclared at the time. I was trying to decide between GIS and intro to computer science for a general requirement. He told me a bit about GIS and geography, and that really won me over. Who knows, I could have been a computer scientist if I hadn’t met him!
Q: You didn’t leave computers entirely though, you’re pretty slick with code… In fact, you’re a great promoter of Python. Which came first – GIS or coding?
A: My first programming/scripting language was Matlab. I learned it while I was working on my master’s studying space-based synthetic aperture radar data in the Florida Everglades. Through learning Matlab, I learned the basics of programming logic. When I started using desktop GIS every day for work, it got me thinking about ways I could be using programming for spatial analysis, which led me down the path to Python. Since then, I use it almost every day, and not just for spatial analysis.
Q: What other tasks do you use Python for?
A: Lately I’ve been using it to prepare transit data for travel demand models. Since many of the inputs of the models are text-based, Python lends itself well to these types of tasks. It can also come in handy for automating things you’d rather not do manually. For example, I had an Excel spreadsheet with multiple worksheets that needed to be saved as individual CSVs. Instead of exporting them one by one, I wrote a script to iterate through each worksheet and save it as a CSV. Kind of a mundane example, but it’s this type of thing that I think can save lots of time at the end of the day.
Q: Speaking of time, you did a transportation study and saved time by scripting some node-based analysis of road segments to bicycle accident occurrences. I saw your talk at the ESRI UC where you talked about becoming one of the points. Do you know if that study has been reviewed by any of the traffic safety folks out in your area, has it helped any?
A: That was one of the first projects where I got a chance to develop a custom script tool for ArcGIS. The tool uses a roadway network and collision data to pinpoint high incident collision areas that might need attention. The tool was applied most recently by Placer County here in California to run a collision analysis of their entire county-maintained roadway network, which used to be a manual review process. They used some of the results to apply for grants and received several grants funding highway safety projects. Another benefit of the tool is that the county can continue to use it with new data in their safety programs.
Q: You’ve taught workshops on Python and even done some online workshops. Do you have any more in the future, or are you branching out to something different?
Q: A few months back you attended my first #maptimeSF with me; now that you’ve moved out to San Francisco I see you get to go to #maptimeSF more often. For someone who is thinking about attending their first Maptime, how do you think it helped you as an advanced GISer?
A: Maptime is a meetup that’s happening in many cities around the world where folks can get together, learn about maps, make maps, talk about maps, or maybe just hang out with friends. One of the things I love about Maptime is that it’s open to all skill levels and backgrounds. People are encouraged to ask questions and learn from each other. It’s a very welcoming environment. I’ve learned a lot about how others outside of my industry are using geospatial data and technologies. It’s also encouraging to see a thriving interest and enthusiasm for maps.
Q: Hearing about your work in transportation is really interesting. The water side still misses you. What are you up to at Fehr & Peers? Any interesting projects you can share with us?
A: I have so many great memories from my time with the Department of Water Resources in West Sacramento — it’s where I really started to get my feet wet (pun intended) with Python! It’s also where I learned to drive a boat. I definitely miss the field work collecting bathymetry data in the Sacramento-San Joaquin delta (picture below for proof), and of course the people too!
One of the great things about GIS is that it’s applicable in many different industries. Transportation planning has a lot of great uses for GIS too. One of the more recent projects I worked on focused on improving cyclist and pedestrian access to transit stations. The project had a large data organization component that involved gathering available spatial data and organizing it in a consistent way so that we could use it in a series of network analyses. We looked at some of the ways that a well-connected network might help improve access to transit, making it easier for people to walk and bike to stations. I’m currently working on a project, also transit-related, that involves improving transit in an area that doesn’t have a lot of existing transit. It can be a challenge to anticipate how new facilities will affect travel in an area if you don’t have many observations on how people are currently using transit. In this case, we’re identifying places that have developed transit networks and that share similar characteristics with the study area that’s considering improving or expanding their transit system. Both of these projects are very much rooted in spatial analysis, but also require local knowledge. Another fun part of my job is getting to know new areas and talking with people to learn about qualities specific to their region that might not be obvious from just looking at the data.
Q: If people are looking to check out some of your cool stuff, where can you be found online?
A: I tweet about spatial topics, transportation, and my endless appetite for spinach @wolfmapper.
Q: Geohipster Amy Smith is awesome! How do you feel about being part of spreading the geohipster gospel?
A: I’m a big fan of GeoHipster! I was trying to disguise myself a bit by using a seriffed font, but I think you found me out anyway.
Q: Speaking of transportation, I’ve got to wrap this interview up so I can cycle to work. Is there anything else you would like to share with #geohipster readers?
A: I recently learned about a spatial data format called topoJSON that’s one of my new favorite things. I found out about it at a recent Maptime on D3 and have been reading more about it on Mike Bostock’s wiki. Also, I’ll be helping host a webinar on transit planning with Code for America next month. Tune in if you’re interested!
