I am downloading geojson from a government agency that uses a hosted AGOL instance. The geojson does not appear to come back in the expected format for any polygons with holes (as shown in https://tools.ietf.org/html/rfc7946#appendix-A )
"A.3. Polygons
Coordinates of a Polygon are an array of linear ring (see
Section 3.1.6) coordinate arrays. The first element in the array
represents the exterior ring. ...
Instead, the holes are returned as additional rings with reverse winding order. Is this the expected geojson format to be returned? Is it a configuration on their server (or hosted service) to specify how holes are represented?
Here is an example using the AGOL viewer (notice the holes)
https://data-nifc.opendata.arcgis.com/datasets/wildfire-perimeters/data?geometry=-125.090%2C39.654%2...
Here is a link to get the geojson returned
https://services3.arcgis.com/T4QMspbfLg3qTGWY/arcgis/rest/services/Public_Wildfire_Perimeters_View/F...
Showing that geojson in QGIS, the holes are seen as "filled in". Same happens with FME.
Any suggestions?
