KeyOSC Mapper

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.

OS Data Hub mapping options:

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’ activities such as the analysis of road accident locations, or as AutoCAD entities to use as a base map for your scheme design. When working with a 3D digital terrain model in Autodesk Civil 3D, OS MasterMap can be draped on the surface, and 3D buildings created from OS building height data.

What People are Saying

There are a number of features within KeyOSC Mapper that make putting engineering drawings together much quicker. The loading buffer feature is great for producing engineering drawings that cover a long length of road and is very quick and easy to use.
