[Gdal-dev] KML Write-only driver for OGR

[Christopher Condit]

Hi Guillaume-
A separate GDAL driver for dealing with KML and rasters would have to be implemented to accommodate this request.  I have a general idea of how GE/rasters work - but there are a few particulars that I don't understand (ie - how to best tile images onto GE?).  It strikes me this could be more in line with creating a world file for a raster image.  If someone can spec out the process I think creating the actual KML file should be trivial...

I think it would be great to be able to read kml too. When using GE, you can
export features into kml. If you have GE pro edition, you can draw features
and save them into kml. These are examples where reading is interesting.

I would also like to raise a new question. KML is also made for displaying
rasters into Google. Would this driver being able to make this.

An interesting link not mentionned in this thread:

Thanks for all this job,

Guillaume.
