[gdal-dev] Editing KML files using ogr_csharp.dll

[Pouliot, Christopher (DNR)]

Hello All,

I have a C# application that uses OGR_CSHARP.DLL to read/write KML files.  I'm able to read from KML files fine.  I'm able to create a new KML file and write to it fine.  I am unable, however, to open a KML file to edit.  I'd like to be able to append a new layer (folder) onto an existing KML file.  I've tried both of the following code snippets:

//This returns NULL
OSGeo.OGR.Driver drv = Ogr.GetDriverByName("KML");
DataSource ds = drv.Open("c:\\temp\\mykml.kml", 1);


//This returns NULL
DataSource ds = Ogr.Open("c:\\temp\\mykml.kml", 1);


I'm able to use this code to edit File Geodatabases and Shapefiles but not KML.



Also, when creating a KML file from scratch is there a way to map the Name and Description fields to my existing fields so that the Name and Description appear in Google Earth?


Thanks,

Chris
