How it works

  1. You choose how you want your data
  2. We cut and prepare the data just for you
  3. You download it when you want to

Hungry for more?

Data Optimiser frees up the time taken to style and translate OS MasterMap and/or OS VectorMap Local into formats suitable for use in GIS and/or CAD systems. Data is simply downloaded from our web portal, which is available 24/7. We even update it quarterly, so you know that the data available to you is the most current available.

OS MasterMap Module – from GML to your GIS

Data Optimiser OSMM processes and translates the following layers:

  • Topography Layer
  • ITN Layer, including Urban Paths Theme

Styling choices – your styling or ours

A parameter file determines the styles that are applied to each feature and the layer to which that feature is written within the constraints of the format. We’ve created two default parameter files appropriate for either CAD or GIS use. Alternatively, a customer’s own parameter file can be applied. This ensures that data looks consistent to users.

Formats – data the way you need it

Data is processed into one of the following formats:

  • MapInfo .TAB
  • AutoCAD .DWG or .DXF

New data – Automatic quarterly updates

Users are automatically notified when updated data has been uploaded to their miso portal. All they have to do is log in and download it at their convenience.
