Updates to Digimap

Over the summer, Digimap have produced a number of improvements which will help compare and combine the different services, and increase interoperability with other mapping applications.

Web Mapping Services

A new button gives access to ‘Web Services’.  This will allow you to export Digimap to other applications like ArcGIS or QGIS, without having to store the data locally. The data can be used as backdrop mapping and there are no size restrictions.  You can also use this function to combine different Digimap services eg Aerial and OS.  Transparency sliders allow you to adjust the visibility of each component.

New overlays in Digimap Ordnance Survey

New overlays available include:

  • Postcodes – based on Codepoint with polygons. Contains the full hierarchy
  • Contours and spot heights – from Terrain50 and Terrain5 datasets
  • Points of interest – point dataset of features. Nine groups, including Retail, Transport and Manufacturing and production

Photographs

Photo of Library on OS Digimap

Include photographs on a Digimap base

Upload your own photographs to a Digimap base! Simply click on the Camera icon on the Drawing Tools panel.  Once added it is treated as a drawing feature and can be moved or resized.

Printing

You can now rquest an A5 print – better for fitting into an essay or report

Search results

Search results are now grouped by type – places, roads, coordinates etc, and shown in different tabs

If you have questions about using Digimap, contact Judith Fox –  j.a.fox@reading.ac.uk

Try out a new census and socio-economic data service

Digimap, the online map and data delivery service, has a new trial service available. In addition to Ordnance Survey, Historic, Geology, Aerial, Environment, Marine and Global, we now have access to Society Digimap.

Society Digimap

Society Digimap example

Digimap Society logoSociety Digimap provides a wealth of census and socio-economic data for Great Britain. Although census data is available through the UK Data Service, the processing required to show census and other demographic datasets on a map can be a barrier to use for many interested in the value of the datasets. By providing these datasets as layers to visualise along with high quality Ordnance Survey data, users can access this rich information source to gain valuable insights for their areas of interest without the need to learn how to use a GIS.

Over 40 layers of data from a range of Census 2011 data, broadband availability and Output Area Classification (OAC) are available. Initially this can be mapped using a Roam mapper, but a download facility is also planned.

Is this service useful?

If you are using or planning to use this service in your teaching or research, please let us know! The trial is available until 31 July 2019.  Please send any feedback about it to Judith Fox, Digimap Site Representative.

New resources from Digimap

We now have two new Digimap services available to University members: Marine Digimap and Global Digimap. These are in addition to Ordnance Survey, Historic, Geology, Environment and Aerial.

Marine Digimap

Marine Digimap is of two types: nautical charts derived from UK Hydrographic Office paper charts and chart panels; and Marine Themes data, which is a feature rich dataset derived from authoritative material obtained from the UK Hydrographic Office.  Both are available to download for use in Geographical Information Systems (GIS) or to produce printed maps.

Marine Roam

Marine Roam© British Crown and OceanWise, 2018.

Marine Roam can be customised and includes layers for:

  • Elevation
  • Shipwrecks and Obstructions
  • Industrial Facilities
  • Transport
  • Administrative and Management Units
  • Geographical Regions

Chart Roam enables you to view and print maps using Raster Charts at one of 11 predefined scales. Marine data is extensively used in offshore engineering projects, management of marine and coastal environments, marine ecology studies, environmental impact assessments and tourism.

Global Digimap

As its name suggests, Global Digimap goes beyond Great Britain, with world coverage derived primarily from OpenStreetMap data, and smaller scales from Natural Earth datasets.  The service is currently in Beta, and Edina would appreciate any feedback or ideas for new datasets.

Global Digimap

Global Digimap © OpenStreetMap contributors

OpenStreetMap data is created by volunteers surveying features on the ground or adding them from Aerial and Satellite imagery.  OpenStreetMap is open data and you are free to use it for any purpose as long as you credit OpenStreetMap and its contributors. However this does mean that the quality of data in OpenStreetMap is very variable, with some features and whole cities being present in very high levels of detail and accuracy and other features are not present at all.

Natural Earth data is created by a group of volunteers around the globe and is supported by the North American Cartographic Information Society (NACIS). Natural Earth is open data and you are free to use it for any purpose.

There is more information about OSM and Natural Earth on Digimap’s help pages.

Global Digimap is available as both data download and Roam.

What’s new in Digimap?

New licence agreements

From 1 August, Digimap (our online map and spatial data delivery service) will implement new licences.  The first time you log in after this date, you will need to agree to the new licences before you can access the service. Log in as usual and follow the prompts – there’s no need to re-register your details.

New look

When you log in, you will see that Digimap has a new look. The homepage has been refreshed, while retaining the easy access and functionality of the  old page.

Digimap home page 2018

As with the current homepage, login is possible either using the ‘Log In’ button in the top right corner or by accessing each Roam or Data Download application directly (see the ‘Geology Roam’ and ‘Geology Data Download’ example below:

Geology Digimap home

More information about the maps and data in each collection is now given, and there is also more detail on how to access the maps and data and easier links to Help information.

New resource – Marine Digimap

As part of the new licensing agreement, we now have access to Marine Digimap. This has two types of data:

  • Nautical charts – derived from UK Hydrographic Office paper charts
  • Marine themes – including elevation, shipwrecks, aquaculture areas, windfarms and navigational features

Marine Digimap could be useful for offshore engineering projects, management of marine and coastal environments, marine ecology studies, environmental impact assessments and tourism.
