Tool to simplify, join and convert GeoJSON or other GIS files
Skill level: 👩🔬 Data scientist
Like GeoJson.io, 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 GeoJson.io tool. Unlike GeoJson.io, Mapshaper doesn’t have drawing tools, so you won’t be able to create geospatial files from scratch.
