ENVIGeoJSON

ENVIGeoJSON

This object is a wrapper around a GeoJSON representation that is stored as an IDL Hash. It is necessary for tasks such as ENVIGeoJSONToROITask that require GeoJSON format.

GeoJSON is a geospatial format based on JSON code that is used for encoding geographic data structures. For more information, see the GeoJSON Format Specification. Also see the GeoJSONLint web page for example code and for tools that validate GeoJSON code.

Example


Refer to the code example for ENVIGeoJSONToROITask.

Result = ENVIGeoJSON(GeoJSONHash)

Return Value

Arguments


GeoJSONHash
