I have published layers from my Azure SQL server. All is working well EXCEPT that the Z values of the points are not returned in the WFS.
The SQL Server instance contains a spatial table which is registered in the geometry_columns table with the following information:
f_table_catalog = testdb
f_table_schema = qc
f_table_name = pts_with_elevation
f_geometry_column = shape
coord_dimension = 3
srid = 4326
geometry_type = point
I have created a store in GeoServer using Microsoft SQL Server vector data source and specified the dbo.geometry_columns table. I published the pts_with_elevation layer and have confirmed in SQL Server that the shape column contains Z values using
select shape.STX, shape.STY, shape.Z, shape.STSrid from qc.pts_with_elevation
which returns e.g.
-121.187741391525 50.5423015254986 1124.495 4326
All records in the table have a Z value.
When I call
https:///geoserver/fieldqc/ows?service=WFS&version=2.0.0&request=GetFeature&typeName=qc%3A pts_with_elevation &maxFeatures=50
only the X and the Y values of the coordinates are included (snippet below)
qc:shape
<gml:Point srsName=“http://www.opengis.net/gml/srs/epsg.xml#4326”>
<gml:coordinates decimal=“.” cs=“,” ts=" ">-121.18951779,50.54197942</gml:coordinates>
</gml:Point>
</qc:shape>
Can anyone please suggest what I might be doing wrong? This is using GeoServer version 2.20.4.
Many thanks,
Patricia
Hi Patricia,
I have not used SQLServer in a long while, but wonder if it might be related to the serialization
flag, among the datastore configuration params: what happens if you flip the native serialization flag (either on or off, depending on what you currently have)?
I see there are tests for “3D” data (actually 2D+1, just like in your case, flat CRS with a third additional ordinate)
and they are currently passing in our builds… so there is at least some 3D support built into the store.
Cheers
Andrea
