I believe that dwithin ignores the units, and will always evaluate the distance
in the units of the layer's CRS, e.g. for EPSG:4326 it uses degrees.
Thanks,

Subject: -EXT-[Geoserver-users] Conversion meters to kilometers or feet in
DWithin filtering
WARNING: This message is from an external source. Evaluate the message
carefully BEFORE clicking on links or opening attachments.
I have used the WMS service with the CQL filter in GeoServer. Currently, I want
to use the "DWithin" spatial operators to filter features by default GeoServer
data ("sf:archsites" layer). I specifically need to filter a specific point
(593250, 4923867) using a radius of 10,000 meters.
I want to substitute meters with something like kilometers.
The issue is that these two commands should produce the same results in the
output, however in geoserver, it doesn't work this way. Why?
Here are the CQL filter codes:
- CQL_FILTER=DWithin(the_geom,Point(593250 4923867),10000,meters)
- CQL_FILTER=DWithin(the_geom,Point(593250 4923867),10,kilometers)
Regards
