I would like to share the original data and code I use in all of the, well, software and code column. I’m using Figshare to host all of this, and will try to keep it organized by column. Here is the data and original code for the first column, with the column found here and the second column found here. Thanks!
The MAPS-L listserv had a note for the following API for querying open source spatial data: https://mingle.io. Check out the “explore” tab to query various spatial attributes such as land use, etc.
If you find other spatial data sources, feel free to post to the Forum and tag your post with “spatial data” so that future subscribers can just search on the spatial data tag for all sources!
