I've recently received some parcel data in shapefile format that has z & m coordinates (all = 0.0). The WKT for a typical parcel looks like this:
"MULTIPOLYGON (((2672464.560700002 711396.4336998622 0.0 0.0, 2672428.060700002 711369.2463998601 0.0 0.0, 2672373.310000001 711454.3723998595 0.0 0.0, 2672410.0600000033 711481.4969998623 0.0 0.0, 2672464.560700002 711396.4336998622 0.0 0.0)))"
This data is not being accepted by my ruby gis program/libraries (rgeo) when I try to parse the WKT. I could use gdal/grass (little to no experience), Python (little to no experience) or some other ruby library, but I'd prefer to sanitize this code of its 3D (Z) and M coordinates using qgis.
Given the fact that this question has been unanswered for days ANY solution would be appreciated, including grass, gdal, other ruby libraries, python, even arcgis (I have a new PC so can do a new 30 day trial...)
