You can now search and download the imagery data from Aerial Digimap by the year it was flown.

This allows you to be sure that you are downloading only the latest data, but it also allows you to download multiple images for the same location taken on different dates. We currently have data from 1998 through to 2016, with more English and Welsh images coming for 2016. When you are in Aerial Download you can see the extents of each year using the Show Availability Grid tool on the right side of the map as shown in the image above.

There is a table below detailing how many 1x1km images there are for each year, with the majority coming from 2013 to 2016, but some of the older images will be very useful to compare to the newer ones where they overlap:

Year Number of Images
1998 165
2000 855
2001 891
2002 75
2003 11
2005 423
2006 4,620
2007 7,799
2008 5,757
2009 25,066
2010 35,607
2011 18,642
2012 16,619
2013 54,534
2014 71,404
2015 81,378
2016 18,769

As you can see there has been construction in the West of the area with new buildings and car parks added.

We hope that you find the ability to make this sort of comparison useful for your research. If you have any questions about this or any other aspects of the Digimap service then please don’t hesitate to contact us.

Aerial imageryAerial Digimap was only launched at the end of last year but the response from the Digimap Community has been amazing. The service already has thousands of active users who have created hundreds of thousands of screen maps. Users have downloaded tens of thousands of square kilometres of this data, for use directly in reports or GIS and CAD software.

 

Data updates

Whilst we’re excited to see such a high level of usage of the new service, behind the scenes our Data Team are currently processing the 2015 data which will be available in the service early next month. This is the first update we have received from the data supplier, Getmapping, and contains updates to around 80,000 tiles. This is a significant update as it covers roughly 30% of the country providing more up to date imagery for a large proportion of Great Britain. The map below shows the likely distribution of the updated 2015 data.

Webinar resources

We recently ran a webinar highlighting the data and showcasing a number of potential uses for the imagery. The webinar was recorded in full and is available on our YouTube channel. The slides used during the webinar and a transcript of all questions and answers are available on our help page.

Data information

The aerial imagery data in the service is 25cm resolution vertical aerial imagery supplied by Getmapping PLC, and is the most detailed aerial imagery available for the whole of Great Britain. As well as being a really interesting dataset the imagery also has a number of practical uses across a wide range of disciplines from urban planning and 3D modelling to land use and archaeological studies.
