Aerial Digimap updates

March/April 2017 has been a busy couple of months for the Data Team who have been working hard to process a huge area of updated aerial imagery data from the data supplier, Getmapping. The update consists of around 80,000 individual 1km tiles, all captured in 2015, which is approximately 30% of the country.

Prior to the update just over 50% of the data was from 2013 or later; after the update 77% of the data is from 2013 or later.

This means that more up to date imagery is now available for viewing and download through Aerial Digimap for a significant proportion of the country.

The map below shows the approximate distribution of the updated data.

This is the first update we have received from Getmapping, but we are expecting another update later this year containing imagery captured in 2016.

We will add this to the service as quickly as we can to ensure that the most up to date data is always available to Aerial Digimap users. In order to make it clear where the data has been updated, we will add an Availability/Reference Grid to Aerial Download so that users can easily identify if the imagery has been updated in their study area(s). This grid will be added to the system in the next couple of weeks.

We are still investigating the best way to make previous versions of the data available, but in the mean time only the most recent data is available through Aerial Roam and Aerial Download.

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 orthophotography 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.

Free Digimap webinar: Creating 3D models from Digimap data – 26 April 2017

ecls/ 21 March 2017/ Digimap News, Of Interest, Training & Events

The Digimap team are hosting a free webinar, on Wednesday 26 April 2017, from 1-1:30pm.

3D model showing bedrock geology of the Cuillin hills in Skye with Aerial Imagery draped over OS Terrain 5 DTM.

The session will give an overview of how to create 3D models in common GIS and CAD packages (ArcGIS Pro, QGIS and AutoCAD) using data downloaded from Digimap.

The session will look at the datasets available from Digimap that are of use for 3D modelling.

You will also have the opportunity to ask questions on any aspect of Digimap.

Registration is required – please note that spaces are limited, so it’s advisable to register early.

Aerial Digimap: huge area of new images coming soon!

ecls/ 3 March 2017/ Data Changes & Additions, Digimap News, Of Interest

Aerial 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.
