[gdal-dev] GDAL does not find geometries from KML

[Rahkonen Jukka (MML)]

Hi,

I found what is the problem. The service is sending old style KML, the current specification has this note:

Note: The <GeometryCollection> tag has been deprecated. Use <MultiGeometry> instead.

Search-replace made GDAL to find the missing  geometries.

Aihe: GDAL does not find geometries from KML

Hi,

I tried to convert geometries from a KML file captured with URL https://www.sedecatastro.gob.es/cartografia/fxcc/fxcc_kml.aspx?refcat=0717611VK4701F

Ogrinfo finds layers
INFO: Open of `0717611VK4701F.kml'
      using driver `LIBKML' successful.
1: 0717611VK4701F
2: PLANTA GENERAL
3: PLANTA BAJA 00

Ogrinfo finds also a POINT Z geometry from layer 0717611VK4701F. By looking at the KML file with a text editor layers PLANTA GENERAL and PLANTA BAJA 00 both contain one GeometryCollection which is made out of one or several POLYGON Z geometries. However, ogrinfo does not find those geometries. The KML file opens with Google Earth and shows a 3D model of a building. Is there perhaps something special in the structure of this KML?
