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:

The following datasets are available through Lidar Digimap at present:

Dataset	Availability and publication date
Digital Terrain Model and Digital Surface Model (DTM and DSM)	England 25cm: 2009-2015 50cm: 2009-2015 1m: 2010-2016 2m: 2010-2015 Scotland Phase 1 (1m): 2011-2012 Phase 2 (1m): 2013-2014 Wales 25cm: 2015 50cm: 2009-2016 1m: 2010-2016 2m: 2010-2016
Point Cloud	Scotland Phase 1: 2011-2012 Phase 2: 2013-2014

 

We are currently processing the following datasets and hope to have them available in the service shortly:

Dataset	Availability and publication date
Digital Terrain Model and Digital Surface Model (DTM and DSM)	England Historical data: 1998-2015 Scotland 50cm 2m
Point Cloud	England 2005-2016
Orthophotographs	England 2006-2015

 

The data was collected for flood risk analysis and modelling and primarily follows water courses and coastal habitats. The data covers approximately 72% of England, 20% of Scotland and 70% of Wales. The image below shows the 1m resolution DTM coverage in England:

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!
