I've got tons of DWG/DXF files with information (in several layers) dealing with:
- Contour lines and elevation (lines)
- positions of antennas (points)
- protection areas (polygons)
- administrative boundaries (lines)
- roads (lines)
- rivers (lines)
- fences (lines)
All this information have been inserted into these CAD files in a non-standard way (not-unified names or colors in layers), and now I want to translate it into GIS (SHP files or into a PostGIS Server).
I'm investigating which is the best wayhow to translate these data in the easiest way.
- create GDAL scripts with Python (http://www.gis.usu.edu/~chrisg/python/2009/)
- create scripts with Teigha libraries (http://www.opendesign.com/guestfiles/TeighaFileConverter)
- use ArcGIS Desktop (with Python scripts) (http://www.slideshare.net/cageyjames/python-scripting-with-arcgis)
- use QGIS or gvSIG (http://www.qgis.org/, http://www.gvsig.org)
- use GlobalMapper (http://www.globalmapper.com/)
- use GeoKettle (http://www.spatialytics.org/projects/geokettle/)
I'd be very grateful if anybody could share their experiences with theCan CAD2GIS translation. Thank you very much in advance. be achieved with this software?
