Has anyone successfully created a workspace that can convert Ordnance Survey MasterMap data to dwg format? I understand the process would be quite complex, but it would be good to get an idea of what’s involved from anyone who may have done this.

Converting Ordnance Survey MasterMap data to DWG format

Hi
I can’t say I have, but it should definitely be doable! I’m guessing that you’re working with the UK OS MasterMap Topography Layer (GML) reader, if that’s right? There’s a few different reader options but this is the newer one to the Non-XSD Driven, GML v2.1.2 Only (DNF) reader.
Do you have any particular concerns getting specific data across to DWG?
I’d suggest giving it a try to read in the data first and see what data you’re working with and how you want it to be structured (by layers) in DWG and then adding a writer to see what you get across first. It’s best to have a template DWG file defined and ready to go for your DWG writer if you have a target for what layers you need, what colours they should be, and line weights, line types … etc.

Hopefully that helps you get started and others in the Community might be able to share some more experiences working with this kind of translation!
