deepgis Posted February 7, 2014 Report Share Posted February 7, 2014 Firstly, you have to classify your image using ERDAS, ENVI, Ecognition software. Secondly, convert your built-up raster class to vector (.shp format) using the mentioned software. 1 Quote Link to comment Share on other sites More sharing options...

Lurker Posted March 8, 2014 Report Share Posted March 8, 2014 after you got the image with classes you really want, you can convert it to shp directly , I use ENVI, and this is how to do http://www.exelisvis.com/docs/Classification.html#ClassExport Quote Link to comment Share on other sites More sharing options...
