Chris,
I don' know OGR very well, but I see a few issues. I also am not sure about
the c# bindings, I believe they are pretty complete though.
'''OSGeo.OGR.Driver drv = Ogr.GetDriverByName("KML");
DataSource ds = drv.Open("c:\\temp\\mykml.kml", 1);'''
Open() opens existing files, you need to use driver->CreateDatasource() to
create datasets. Open() opens files for editing. If mykml.kml exists, use
Open().
see http://gdal.org/ogr/ogr_apitut.html for information on using OGR to
read/write data
'''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?'''
See http://gdal.org/ogr/drv_kml.html for this, it appears to be possible.
There is also the libkml driver: http://gdal.org/ogr/drv_libkml.html

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