Re: [gdal-dev] Where to find a FlatGeobuf test file?

Jukka, I'm not sure how poly_no_index.fgb was generated. Perhaps no with OGR or perhaps with an earlier version that didn't write the layer extent in the FlatGeobuf header. The extent is optional, and this file doesn't have one. To test the presence of the spatial index use TestCapability(o

Hi, All right, TestCapability(ogr.OLCFastSpatialFilter) is the answer gdal - How to check if FlatGeobuf layer has a spatial index? - Geographic Information Systems Stack Exchange. -Jukka Rahkon

Hi, Has there been a change in writing the layer extent? I thought that the test https://github.com/OSGeo/gdal/blob/e4d1f7ff474ceeffd69b1ceef3fa635428788e8c/autotest/ogr/ogr_flatgeobuf.py#L182 is testing with TestCapability(ogr.OLCFastGetExtent) if spatial index exists. At least the test file
