I have been using Argis 10.1 and been able to convert polygon m to polygon shapefiles. I would like to do this with QGIS but I am having difficulty in finding the correct tool to do so.

Please Help


I imagine you want to convert Multipart Shapefiles to Singlepart Shapefiles.

The tool you want is: Vector>Geometry Tools>Multipart to singleparts

If this is not the case you need to clarify your question. How do you do it in ArcGIS?


If you have QGIS installed you may use OSGeo4WShell for this. The command would be something like this:

ogr2ogr -f "ESRI Shapefile" C:/Temp/countries.shp C:/Temp/countriesZM.shp -lco SHPT=Polygon

AND to convert to ZM it would be:

ogr2ogr -f "ESRI Shapefile" C:/Temp/countriesZM_2.shp C:/Temp/countries.shp -lco SHPT=PolygonZ

MMGIS's Geometry Convert can also help you drop the m and z and generate a new shp file.
