Integrate TopoJSON Topological Data Using FME

TopoJSON (Topology JavaScript Object Notation) files are used to represent topological features in a geometrical simplistic way. As an extension of GeoJSON, TopoJSON has been designed to model your data simply in files that are just a fraction of the size of a typical GeoJSON file. Use FME to convert your data into TopoJSON. FME supported formats include:

  • Shapefile
  • GeoJSON
  • KML

View all the supported formats and applications in the Integration Gallery.

About TopoJSON

TopoJSON is an extension of GeoJSON that encodes topology in a way that eliminates redundancy and allows related geometries to be stored efficiently.
