Digimap: Data download and WMS

An introduction to online maps and map data via EDINA's Digimap database

Downloading data

Each collection in Digimap has a separate data download tool. They follow similar steps:

  1. select area
  2. select data sets
  3. add to basket (select options e.g. format, map date, layers, etc. – varies by product)
  4. select formats
  5. request download

Unzipping downloaded files:

  • Standard Windows unzip facility should work to extract the downloaded data
  • Keep the various sub-files together, e.g. SHP files. There will be conditions of use files for each data file
  • Map data is typically used by our students with AutoCAD, GIS and/or VectorWorks software
  • You may need to translate data files to another format depending on the software you are using

You can bring in map data from other sources (e.g. gov.uk) and add them into the Roam application via the Overlays options in the left-hand menu:

  • Search for a feed, select and add it (keyword search for approved feeds by theme e.g. marine)
  • You can de/select layers from the Overlays options and change the transparency of the overlay

You can also add map data from one collection in Digimap to another:

  2. Go back to the Digimap homepage and open collection you want to add it to (e.g. Ordnance Survey) and click Roam
  3. Click on the Overlays option in the left-hand menu
  4. Select the WMS tab, then click the Manually add WMS feed button
