I'm trying to develop a workflow where I can convert a
.dwg file to
.shp. I don't have a good understanding of which tools I should be using. My preference is to use software that runs on
OSX, is open-source (or free).
My current workflow is as follows:
.dxfusing Draftsight (http://www.3ds.com/products-services/draftsight/overview/ )
- Scale/rotate imagery in
- View in
Once I reach step 4, I'm unsure how best to proceed. As far as I can tell,
Google Earth is actually rendering a
Collada model, and not loading a
kml file that I can access, so I don't know how to extract the underlying file.
I thought about using
ogr2ogr (http://www.gdal.org/ogr2ogr.html ) but I'm not sure if I can interact with a
CAD file this way (as I need to specify the projection and location). I also have
PostGIS available. I also considered
FME but would prefer not to have to have a Windows OS just for this conversion process. I've also read through the following related question:
Transforming from DWG/DXF to GIS?
