What is Roam?

Our Roam mappers allow you to view, customise and print our maps. They all work in the same way but some collections offer additional features to let you make the most of their particular maps. The image below shows Ordnance Survey Roam:

OS Roam

Here, we look at the 3 key areas of Roam and the tools within each area.

Map window

The main area of Roam is the map window, where you zoom in/out, move around the maps and can often change basemap.

  • A scale bar is available to help you zoom in/out of the different map views.
  • Map view names are displayed at the bottom right of the map window.
  • Basemap selection is available on the map window in several, but not all, collections.
  • A map opacity slider bar is available in some collections, to allow you to adjust the transparency of the maps.

The sidebar, on the left of Roam, contains several tools, including:

  • Map content - depending on the collection, you may be able to select which map features you wish to display.
  • Drawing Tools, which allow you to add text, symbols, shapes and buffers.
  • Measurement tools to measure distance and area.
  • Map information where you find coordinate information and details of the map data you are viewing.
  • Overlays - depending on the collection, you may be able to add an overlay such as hillshading to your map window.
