Description
With VMap0 there are many cases where a default geometry is not set on a feature even though there is a geometry attribute in the feature. The attached program will illustrate the problem when run against VMap0 data (tested against EURNASIA Ed: 003). Below is a small sample of the output of this program:
Default Geometry is null for: Feature[ id=fid-17f1ba3:1026a8cc89f:-77f4 , id=2 , f_code=BA010 , edg_id=2 , libref.lft_id=2 , start_node=2 , end_node=3 , right_edge=2 , left_edge=3 , coordinates=LINESTRING (58.7053337097168 81.62566375732422, 58.716251373291016 81.62711334228516) ]
