GeoJSON Vector Files

Touchstone 5.1 and later support the import of GeoJSON vector files (.json and .geojson) as map layers. You can then visualize your exposure data with the imported map layers and run geospatial analyses with the map layers.

GeoJSON is a dialect based on the JavaScript Object Notation (JSON). JSON is a lightweight plain text format for data interchange and GeoJSON is nothing other than its specialization for geographic content.

You can import the following geometry types, where polygons are imported as polygon objects, lines as lines, and points as points.

•       Line

•       Point

•       Polygon

•       Multi-point

•       Multi-line

•       Multi-polygon

You can import projected GeoJSON files.
