Social Science Data Curator and GIS Librarian

QGIS is an open source, community built tool to view, analyze and create geospatial data and maps. QGIS is a robust tool that is capable of doing sophisticated spatial analyses. It’s easy to use and facilitates elegant map creation. You can explore both raster and vector data, as it’s capable of bringing in various formats and services.

Postman (API platform) This tool has been a lifesaver when it comes to exploring and troubleshooting calls to web APIs. It is easy to set up a web service call with the appropriate parameters and test the response. It also offers code snippets if you need to port the API call to a script. There is so much more to the platform, but so far I have just used for API testing.
