Environment Digimap

  1. 1. Environment Digimap James Crone – Geo User Support Vivienne Carr – User Support
  2. 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.’ http://www.ceh.ac.uk/la ndcovermap2007.html
  3. 3. Content • Environment Roam – Recreate an example map • Environment Download – What map data is available to download? – How do I use the download service? • Other sources of data Digimap Training Workshops
  4. 4. Environment Roam Save within Digimap, Print A4-A0 Map Content, Map Information Search, Map tools, Overlays, Bas emaps Zoom in/out, 11 fixed scale map views of Land Cover maps
  5. 5. Environment Roam: Map of Dartmoor • Place name search • Zoom out • Change basemap • Change opacity of Land Cover data • Import file that displays Nature Reserve areas • Label the Nature Reserve
  6. 6. Search • Can or pan/zoom to your location ,or use Search • Place name/ full postcode • Advanced Search offers British National Grid reference search • Coming soon: postcode districts e.g. EH9, street names
  7. 7. Zoom in/out • Map centred on Dartmoor • Now I can zoom in/out and pan around Digimap Training Workshops
  8. 8. Navigation • Zoom in/out – Click on any notch on the scale bar – Double click to zoom in – Scroll wheel on mouse • Pan – Click and drag the map – Click on NSEW on the compass • Full extent / Previous / Next views
  9. 9. Map Content
  10. 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. 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 the Land Cover at that point Image shows similar feature in Geology Roam
  12. 12. Basemaps • Basemaps offers Land Cover maps from different dates • 2007 is the default • Can switch to 2000 or 1990
  13. 13. Opacity of Land Cover data
  14. 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. 15. Map with imported file
  16. 16. Annotation tools • Can add shapes, lines, labels and markers • Easier to select format (font size, colours, line widths) before you draw
  17. 17. New print interface
  18. 18. New print interface What’s new? • Content and Layout Previews • Legend option
  19. 19. Map and legend • If you add the legend option, receive a zip file. • Extract the files to see 2 PDF files, map and legend
  20. 20. PDF print example
  21. 21. Legend extract
  22. 22. Save • Save > My Maps saves your map within Digimap – No limit to number of maps you can save – Available as long as your registration remains active • Open > My Maps to retrieve your saved maps
  23. 23. Display annotation in another Roam
  24. 24. Display annotations in another Roam
  25. 25. Export annotations • Save > Annotations to file, to export annotations • 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 Digimap Training Workshops
  26. 26. Content • Environment Roam – Recreate an example map • Environment Download – What map data is available to download? – How do I use the download service? • Other sources of data Digimap Training Workshops
  27. 27. Environment Download
  28. 28. What data is available? • 25m and 1km resolution raster data for each Land Cover map • 25 x 25 m raster gives most likely Broad Habitat for each pixel • 1 x 1km raster summarises the 25 x 25m • Vector data available for Land Cover 2000 map
  29. 29. How does the download service work? • 1 Select area (must have area highlighted on the map) • 2 Select map data – check the boxes • 3 Add to basket – Give order a name – Click Request Download
  30. 30. Basket • Give order a name • Click Request Download What next? • Receive 2 emails from Digimap, 2nd will contain link to download data file
  31. 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. 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: http://www.geostore.com/environment-agency/WebStore?xml=environmentagency/xml/ogcDataDownload.xml
