I have been playing around with maps a lot these days and have ended up using various tools in the process. This blog post is a way to make a note of these tools for later use.
geojson.io
Mapbox’s geojson.io is a simple tool for creating, editing and sharing maps. It lets you import map data in various formats and has an editor to modify maps.
GeoJSON-TopoJSON
Jeff Paine’s GeoJSON-TopoJSON is a simple tool to convert between the more common GeoJSON format and the TopoJSON format used by libraries like D3.js. It is a simple tool, but it does exactly what it says on the tin.
The Distillery
The New York Times’ Shan Carter built The Distillery, a GUI around TopoJSON. Apart from converting GeoJSON to TopoJSON, it allows you to alter the map’s projection.
ogr2ogr
ogr2ogr is a command line utility to convert features data between different file formats.
Ogre - ogr2ogr web client
Ogre is a web UI around ogr2ogr. It lets you do transformations on your map files when you are lazy and don’t want to use the command line to run ogr2ogr.
merge-geojson-features
merge-geojson-features is a Node.js module to combine Features defined in different files in to a single FeatureCollection. I use it when I am not in the mood to alter GeoJSON objects from a JavaScript console by hand.
