Translating MasterMap Data to DWG with InterpOSe


Once you have downloaded the MasterMap data from Digimap you will need to translate the GML format file into AutoCAD DWG format. This relatively simple task can be completed using a small application called InterpOSe, available from Dotted Eyes and free to Digimap users. You will need to download this software and install it on your PC in order to translate from GML to DWG. Once installed, you can translate as many files as you like.

This tutorial takes you through the process of downloading InterpOSe and then using it to translate the data we downloaded in the previous tutorial and viewing it in AutoCAD.
