- Digimap Roam allows users to view and interact with Ordnance Survey maps, including adding annotations, selecting map features, importing external data, and printing maps. - The webinar demonstrated Roam's tools using examples of mapping a mountain area, archaeological site, and flood warning areas, showing how to search, measure, change basemaps, add shapes and labels, save maps, and import external data. - Questions from users are welcomed and additional training and resources are available to help users make the most of Roam's mapping capabilities.

13. Map Content
• Feature selection available in 8 of
Roam’s 14 views
• Unavailable when you are viewing a
raster map - when unavailable, you will
see the message ‘View has no layer
selection’
• TIP: check the basemaps for alternative
maps where feature selection may be
possible

14. Raster v Vector map data
• Raster map data is a matrix of
cells (or pixels) in a grid:
– scanned maps, digital aerial
photographs, satellite images,
digital pictures.
– geo-referenced, geographic
coordinates of the location
added.
– useful as background for
displaying other data.
• Vector map data stores data on
individual map features e.g.
– Points such as train stations.
– Lines such as railway tracks and
rivers.
– Polygons such as buildings or
fields.
– We can view, query and analyse
vector map data.

15. Measurements

or areas
• Not possible to
save the
measurements or
print on your map

views, switching basemap means you

of basemaps are vector.
