Bldg Shapefile (polygon zm) Calculations

Discussion created by gaiaearth on Dec 20, 2010
Hi. I have a buildings shapefile that shows geometry as a polygon zm. (If I remember correctly that is probably from an original conversion from points to polygons.... and I believe this has 3 dimensions. Please correct me if I'm wrong.)

My objective is to calculate square footage of these buildings assuming the z value would be the height. This is a vector file - does anyone have a script or know which tools.....OR do I need to convert this to raster first. Please help - thank you.
