Lidar Digimap: new collection of data available now!

ecls/ 6 June 2017/ Data Changes & Additions, Digimap News, New Features

Lidar Today we have launched our new Lidar Digimap Collection. The new Collection is available to preview for all Digmap users until the 31st of July 2017. Lidar data can be downloaded through the Lidar Download for use in GIS and CAD applications; there is no Lidar Roam application for viewing the data.

The service allows you to download current and past Lidar data from the Environment Agency (EA), Natural Resources Wales (NRW) and Scottish Environmental Protection Agency (SEPA).

There is already a large amount of data available in the service but we are still processing some of the datasets. Once it has all been processed the service aims to have complete coverage of all the data available from these agencies, including the raw LAS point cloud data and Orthophotography captured during the flights (where available).

Lidar data is very useful when creating 3D terrains and models as can be seen from the images to the left and below. For creating 3D scenes such as the one below, it is very useful to use a Digital Surface Model (DSM) to create a surface and hillshading from which you can drape other data over, such as the imagery from Aerial Digimap in this example:

We are also very keen to know what you have been doing with Lidar data in the past or what you plan to do with the Lidar data you are going to get from the new service. To find out this information from you we have put a survey in the interface and you have the chance to win a £20 Amazon just for filling it in!

New Contact Us system launched across all Digimap Collections

ecls/ 30 May 2017/ Digimap News, New Features, Of Interest

As part of our continuous work to improve Digimap and make it more user friendly, we recently added a new Contact Us system. The new system is available in all Digimap Collections and guides you to useful help resources based on what it is you want to know:

Contact Us - stage 1 — Contact Us – stage 1

If you are not able to find the answer to your question using the resources then you are asked to complete a short form outlining the problem you are experiencing:

Contact Us - stage 2 — Contact Us – stage 2

If you are logged in to Digimap you have the option to submit the completed form to either the local Digimap support team at your institution or to the Digimap Helpdesk at EDINA. All queries submitted by users who are not logged in to the service are automatically routed to the EDINA Digimap Helpdesk. The details are sent by email, and copied to you so that you have a full record of what was asked. The new system has been available since the beginning of May and is available from the all Contact Us links in the Roam and Data Download clients, as well as the Contact Us link on the footer of the Digimap home page:

We hope you like using this improved feature, but if you have any questions or comments regarding this or anything else to do with Digimap, please get in touch using the email address below, or try out the new Contact Us form in Digimap!

Massive area of updated Aerial Imagery and other Digimap dataset updates in March/April 2017

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

Canworthy solar farm — Canworthy Solar Farm, which became operational in 2014 and covers approximately 55 hectares (~67 football fields)

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.

Cruise liner in Firth of Forth — Cruise liner in the Firth of Forth

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.

Subscribing

To see if your institution already subscribes to Aerial Digimap, please see our subscribing institutions help page. Information on how to subscribe to the new service is available on the Aerial Digimap Subscription page.

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.
