LiDAR: High resolution land surface elevation data

LiDAR — Light Detection and Ranging is a mapping technique, which uses a laser to measure the distance between the sensor and the ground. Up to 100,000 measurements per second are made of the ground, allowing highly detailed terrain models to be generated at spatial resolutions of between 25cm and 2 metres. UBDC’s 2003 dataset provided by Bluesky International Ltd, can be supplied as a Digital Surface Model produced from the signal returned to the LIDAR (which includes heights of objects, such as vehicles, buildings and vegetation, as well as the terrain surface) or as a Digital Terrain Model produced by removing objects from the Digital Surface Model.

These accurate models have uses for local government planners who need detailed structural plans of the city. LiDAR is also regularly used by archaeologists, computer scientists, and civil engineering companies. UBDC holds 1m LiDAR Digital terrain model (DTM) and digital surface model (DSM) off-the-shelf data for 262 sq km covering Glasgow. Data can be used for research in urban morphology and green analysis, flood risk modelling, solar radiation assessment and more.

Additional LiDAR data in Scotland is available from the Scottish Remote Sensing portal

Glasgow City Council also has 3D building models, that are openly available for everyone to use

Access and Restrictions

UBDC shares the LiDAR 2003 data from Bluesky International Ltd. Data available for non-commercial academic research under UBDC’s End User Licence Agreement. Teaching use not permitted.

Content

UBDC holds 1m LiDAR DSM/DTM off-the-shelf data for 262 sq km covering Glasgow shown as green in image below (the red polygon was the area searched for coverage). It was captured in 2003 from an airborne LiDAR survey so the data will have been constructed from multiple flight paths over the city.
