Tool to simplify, join and convert GeoJSON or other GIS files

Platform: Web
Price: Free
Skill level: 👩‍🔬 Data scientist

Like, Mapshaper is a free, open-source editor that can convert geospatial files, edit attribute data, filter and dissolve features, simplify boundaries to make files smaller, and many more. Mapshaper’s edit and join commands are much more powerful than the tool. Unlike, Mapshaper doesn’t have drawing tools, so you won’t be able to create geospatial files from scratch.
