Drag and drop, or use the upload button to put a geojson file, topojson or a zipped shapefile onto a map. (geojson and topojson can also be zipped)

The shapefile is parsed to GeoJSON using shapefile-js, which I also wrote, which uses DataView and array buffers to parse this mixed endian file. There are also promises used in here, kids these days like promises right?

If you need a file to show there is a zipped shapefile of the world here http://calvinmetcalf.github.io/shapefile-js/files/TM_WORLD_BORDERS_SIMPL-0.3.zip

There is a large amount of geojson in these repos

- https://github.com/calvinmetcalf/CambridgeOpenData (also has topojson)
- https://github.com/calvinmetcalf/MassGIS
- https://github.com/where-gov/dc-maps
