Much of my previous job related GIS work was in the oil industry and therefore proprietary products I can only talk about in approximate terms. While in oil and gas, I used ArcGIS to make maps that stayed on individual computers and servers. Over the last couple years, I’ve switched to using open-source tools to build web-based maps using tools like GeoPandas, Altair, cartoDB, d3.js, mapbox.js, and leaflet.js. A lot of my map projects have been side projects associated with Sketch City or Houston Data Visualization Meetup. Often, I use open-data from civic sources like the City of Houston Open Data Portal.
Some of the side projects that have included map elements are:
- Glasstire hackathon project that visualized the spatial distribution of art gallery showings vs. advertised science jobs in the city of Houston.
- Immediately after Hurricane Harvey, I merged city appraisal data with FEMA mapped estimated damage with Python and visualized in Tableau to enable easier data exploration.
- Although there are domain specific libraries for visualizing LIDAR data, I spent a weekend figuring out how to transform a small open-source LIDAR dataset for self-driving cars into something three.js could visualize, just because.
