st_geomfromgml multipoint issue

Reported by: fordfrog Owned by: strk
Priority: medium Milestone: PostGIS 2.0.2
Component: postgis Version: 2.0.x
Keywords: history Cc: petr@…


using postgresql 9.1.4 and postgis 2.0.1 on linux amd64

this query should return gml string but instead returns empty result:

test=# select st_asgml(st_geomfromgml('<gml:MultiPoint xmlns:gml="" gml:id="DOB.545058.X" srsName="urn:ogc:def:crs:EPSG::2065" srsDimension="2"><gml:pointMembers><gml:Point gml:id="DOB.545058.1"><gml:pos>496547.00 1139895.00</gml:pos></gml:Point></gml:pointMembers></gml:MultiPoint>'));


(1 row)

there is probably general issue with reading the result of st_geomfromgml created from gml:MultiPoint element containing gml:pointMembers. tests with elements with gml:pointMember (singular) within gml:MultiPoint worked fine for me. unfurtunately the data i am processing use gml:pointMembers.

i just noticed i am using postgis 2.0.0, gonna try that with 2.0.1 and will report back

comment:2 by fordfrog, 12 years ago

so postgis 2.0.1 is affected too

comment:3 by fordfrog, 12 years ago

when using st_astext(), it returns "MULTIPOINT Z EMPTY". also, looking at the code, there is no string pointMembers, just pointMember, so it seems support for this element is missing.

The issue will also occur with MultiCurve and MultiPolygon, where in particular the parser only matches curveMember and polygonMember etc. I can try to fix all these issues if no one is working on it

comment:5 by strk, 12 years ago

I think nobody is working on this. Please don't forget test cases

comment:6 by kashif, 12 years ago

great will send you a patch by the weekend with tests of course :-)
