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
• Feature
identification
tool will be
added in March
2014
• Will be able to
click on the map
and get details of

12. Basemaps
• Basemaps offers Land Cover
maps from different dates
• 2007 is the default
• Can switch to 2000 or 1990

13. Opacity of Land Cover data

14. Import Nature Reserve areas
• 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
• We have a Shapefile of Nature
Reserves
– Source of this data is the Natural
England website

15. Map with imported file

16. Annotation tools
• Can add shapes, lines, labels and markers
• Easier to select format (font size, colours,
line widths) before you draw

• Could then use in GIS/CAD,
combine with your own data etc
• Formats:
– Shapefile can be used in most
GIS/CAD software
– KML can be displayed in Google
Earth
– GeoJSON useful for displaying in
web maps

31. Other useful data sources
From the European Environment Agency:
(1) Urban Atlas - provides reasonably high-resolution vector land
use & land cover for big cities Europe wide
http://www.eea.europa.eu/data-and-maps/data/urban-atlas
(2) Corine Land Cover - provides seamless vector & raster land
cover data across Europe
http://www.eea.europa.eu/data-and-maps/data/clc-2006-vectordata-version-2

32. Other useful data sources
Environment Agency provides lots of datasets through their
GeoStore, many of which are available to download under the
liberal OGL (Open Government License) here:
