bug in GML writer for multipoints

[Eijnden, Bart van den (AGI)]

Hi Mateusz,

that is also my conclusion (I have patched my local copy already).

I have opened up bug 1847 to track this issue.

Best regards,

I'm not a MapServer developer but just to sleep well ;-) I checked if
this problem applies to the OGR. And it does not :-)
OGR outputs correct schema of MultiPoint geometry in GML 2

After quick look at the MS code, the problem is in mapgml.c file, in
function gmlWriteGeometry_GML2. This function constructs GML geometry
output and it does not include gml:pointMember for MultiPoint.
Other Multi* geometries should be OK, with *Member elements included,
as I see in the code. So, only MultiPoint is broken.

BTW, there is also gmlWriteGeometry_GML3 function which does output
gml:pointMember element.


Best regards
