Ordnance Survey Mapping in AutoCAD

KeyOSC (‘Ordnance Survey Companion’) Mapper is an application providing an easy way to access Ordnance Survey GB mapping in AutoCAD, with performance akin to GIS systems. Connect directly to the online OS Data Hub or to your own locally managed, on-premises datasets. KeyOSC Mapper also provides simple plotting tools to help you build scaled outputs, and rotated views linked to a north point.

OS Data Hub (online)

KeyOSC Mapper allows you to connect your AutoCAD directly to the online OS Data Hub and give you access to the most up-to-date and useful mapping datasets. Search by address or zoom and pan to find your required area of interest then “fix” the background to convert this to AutoCAD entities that can be edited just like any other feature.

KeyOSC Mapper will allow you to additionally connect to your in-house spatial database or tile-based system to load directly into AutoCAD. This enables OS MasterMap data, stored in an Oracle, SQL Server or PostGIS database, to be loaded within the AutoCAD environment. It can also interact directly with a range of corporate datasets.

Mapping data can be loaded into AutoCAD using current view, polygon and buffer filters and can be used as a simple, transient overlay, supporting ‘GIS’.

KeyOSC features

Toggle Area Fills
Automatic loading of data can be controlled by the toggle area command. Save printing costs by setting the area fills to ‘off’.
Work in 3D on your Digital Terrain Models
Use Ordnance Survey Terrain 5 data to quickly produce a surface model in Autodesk Civil 3D. KeyOSC Mapper will automatically drape MasterMap onto the model and uses the Building Height data to create 3D buildings.
