Toolkit for converting shapefiles into a single TopoJSON file for use in D3.
This docker is made to allow anyone to convert shapefiles into json files for D3.js.
Based on this blog post http://bost.ocks.org/mike/map/
TopoJSON is an extension of GeoJSON that encodes topology. Combined with fixed-precision encoding for coordinates, TopoJSON is usually much smaller than GeoJSON.
The big multitool to know is the Geospatial Data Abstraction Library. Commonly referred to as GDAL, it includes the OGR Simple Features Library and the ogr2ogr binary we’ll use to manipulate the Natural Earth shapefiles.
