UK-England Elevation Model (LIDAR)
Introduction
The UK - England Elevation Model (LIDAR) in 10m grid resolution is a digital terrain model (DTM) produced from higher resolution LiDAR scans originally obtained from the Environmental Agency. The original model at 2m resolution is named ‘LIDAR Composite DTM 2019 - 2m’. The derived elevation model delivered with windPRO is at 10m resolution - this is done in order for the data to be operational for the large areas needed in the context of wind farm analyses. Coverage for the data is approximately 85% of England.
Dataset Overview
- Spatial Coverage: 85% of the UK-England territory
- Resolution: 10 m
- Data-type: Digital Terrain Model (DTM)
- Coordinate system (original data):
- Horizontal: OSGB36 British National Grid (EPSG: 27700)
- Vertical: Elevations recorded above Ordnance Datum Newlyn
- Version: Data downloaded in December 2019.
- Vertical Accuracy: N/A
Usage Notes
- Since only 85% of the territory is covered by the LiDAR scans - you may need to void-fill some areas. If you download the data into an elevation grid object, these void-areas can easily be filled with other ready available sources such as the 50m gridded data from OS Land Form or OS Terrain 50.
- Higher resolution data exist for selected areas in the region based on more recent LiDAR surveys: These are in resolutions from 0.25m to 2m – and may be accessed directly from the UK Open Data web-site (see link below).
Availability from within windPRO
The data are available directly from within windPRO in 10-meter grid resolution. The data can be accessed from the online-services in the following objects:
- Line Object (with purpose to height contour lines)
- Elevation Grid Object
