LIDAR

In recent years, height data has become a vital component of many geospatial strategies and is widely used by government agencies and the commercial sector for a variety of applications from flood risk modelling to wind farm site selection, archaeological exploration to urban planning.

LIDAR (Light Detection and Ranging) is now commonly accepted as the most powerful technique for delivering highly accurate height data in a timely and cost-effective manner and Geomatics Group has been at the forefront of its use in the UK for the past 11 years.

What is LIDAR?
Aerial LIDAR uses a laser to measure the distance between the survey aircraft and the ground surface, including buildings and other assets (above ground pipelines, highways, street furniture, power lines, railway tracks), as well as vegetation. Geomatics Group owns two state-of-the-art Optech LIDAR systems, which allow very high resolution data to be collected at a range of flying heights.

We offer a variety of elevation data products, all with a vertical accuracy in the range of 5cm to 15cm, with spatial resolutions ranging from 25cm to 2 metres. Our archive of LIDAR data, collected over an 11 year period, is constantly being updated and we now have 62% coverage of England and Wales, including many major urban areas and rural flood plains.

To download our LIDAR catalogue or to order data using our interactive map, visit our online store.

In addition we are also available to carry out commissioned surveys and are more than happy to put together an integrated survey utilising a number of remote sensing techniques and tools (hyperspectral, bathymetry, thermal and aerial photography), to meet your specific requirements. Contact us to discuss your survey requirements.

Quality
Geomatics Group have developed processes that allow surface objects such as vehicles, buildings and vegetation to be identified and removed, producing 'bare earth' Digital Terrain Models (DTM). Our standard product delivery includes the DTM, as well as the DSM (Digital Surface Model; where all surface objects are included).

Since 1998 we have been providing the Environment Agency’s Flood & Coastal Risk Management team with LIDAR data, which is then used to update the Flood Map and to help the Agency’s flood risk assessment and planning. Learn more about the Environment Agency's Flood Maps...
