Hi,
I'm use quite often the GML capability of gdal.
this is the tags I normally use and GDAL actually recognize
(these are not the only tags recognized from Gdal) :
<gml:LineString srsName="urn:ogc:def:crs:EPSG:3003">
<gml:posList srsDimension="2">...</gml:posList>
</gml:LineString>
<gml:Point srsName="urn:ogc:def:crs:EPSG:3003">
<gml:pos srsDimension="2">1713658.01 4864821.19</gml:pos>
</gml:Point>
<gml:MultiPoint srsName="urn:ogc:def:crs:EPSG:3003">
<gml:pointMember>
<gml:Point>
<gml:pos srsDimension="2">...</gml:pos>
</gml:Point>
</gml:pointMember>
</gml:MultiPoint>
<gml:MultiSurface srsName="urn:ogc:def:crs:EPSG:3003">
<gml:surfaceMember>
<gml:Polygon>
<gml:exterior>
<gml:LinearRing>
<gml:posList srsDimension="2">...</gml:posList>
</gml:LinearRing>
</gml:exterior>
<gml:interior>
<gml:LinearRing>
<gml:posList srsDimension="2">..</gml:posList>
</gml:LinearRing>
</gml:interior>
...
<gml:interior>
<gml:LinearRing>
<gml:posList srsDimension="2">...</gml:posList>
</gml:LinearRing>
</gml:interior>
</gml:Polygon>
</gml:surfaceMember>
</gml:MultiSurface>
<gml:Polygon srsName="urn:ogc:def:crs:EPSG:3003">
<gml:exterior>
<gml:LinearRing>
<gml:posList srsDimension="3">...</gml:posList>
</gml:LinearRing>
</gml:exterior>
</gml:Polygon>
And just today I finish to write a little patch to add the capability to
read this
new tags (that is generated from postgis ST_AsGml() ).
<gml:MultiCurve srsName="urn:ogc:def:crs:EPSG:3003">
<gml:curveMember>
<gml:Curve>
<gml:segments>
<gml:LineStringSegment>
<gml:posList srsDimension="2">...</gml:posList>
</gml:LineStringSegment>
<gml:LineStringSegment>
<gml:posList srsDimension="2">...</gml:posList>
</gml:LineStringSegment>
</gml:segments>
</gml:Curve>
</gml:curveMember>
<gml:curveMember>
<gml:Curve>
<gml:segments>
<gml:LineStringSegment>
<gml:posList srsDimension="2">...</gml:posList>
</gml:LineStringSegment>
</gml:segments>
</gml:Curve>
</gml:curveMember>
</gml:MultiCurve>
I will send surely this patch to Frank and Chaitanya to add to GML
reader if it is quite good for gdal.
Regards,
Andrea Peri.
Hi,
GDAL/OGR release news says that ogr has now "Limited support for GML3".
Unfortunately the documentation is limited as well, at least at
http://gdal.org/ogr/drv_gml.html. What can ogr do now with gml3? What
interests
me most is that how well it can interpret gml3 that comes out from WFS
1.1.0
servers.
