I'm using GDAL 1.10.1 for reading ArcGIS Server responses with automatic conversion to GeoJSON format as described in Converting ArcGIS Server JSON to GeoJSON? post.
However, it looks like some of the Feature Servers published by ArcGIS return empty results when queried using the above technique: http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/BloomfieldHillsMichigan/LandusePlanning/FeatureServer/2/query?where=objectid+%3D+objectid&outfields=&f=pjson
Could someone explain why the technique is not working for some data? Any pointers to how this query-based conversion works in general would be appreciated.
