The document provides an overview of the Digimap service, focusing on land cover data from the Centre for Ecology and Hydrology and its various features, including data downloading options, map customization tools, and the upcoming feature identification tool. It discusses different map data types, such as raster and vector data, methods for importing and annotating maps, and resources for training workshops. Additionally, it lists other useful data sources and provides contact information for user support.

2. Environment Digimap
• Land Cover data from
the Centre for Ecology
and Hydrology – 1997,
2000 and 2007
•
•
‘It has been derived from
satellite images and
digital cartography and
gives land cover
information for the
entire UK. Land cover is
based on UK Biodiversity
Action Plan Broad
Habitats.’

10. 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.

11. Feature coming soon

• Possible to import your own
map data to Roam
– Various formats can be imported
– Only importing the point, line or
polygon, not any associated
information

Reserves
– Source of this data is the Natural
England website
