We are pleased to announce this week the first release of data from Scotland\u2019s new national land Light Detecting and Ranging (LiDAR)<\/span> programme, delivered by the Scottish Government with multiple partners. The goal of the programme is to sustain the nation and enhance well-being and the economy through a profound improvement in the mapping of our environment.<\/p>\n

The Scottish Land LiDAR Programme is running from May 2025 \u2013 July 2027. By January 2026 around 15% of Scotland has been mapped. Data are being released in blocks when all products have been processed.<\/p>\n

Today the first two blocks, totalling almost 2000 square kilometres (2.5%) of Scotland\u2019s land mass have been uploaded to the remotesensing.gov.scot<\/a> portal for open, public access. The new data have been collected at high resolution, 10 points per square metre, giving unprecedented details of Arran and other western areas. Further data releases are expected at approximately 6 month intervals through the programme to provide full national coverage above high tide.<\/p>\n

The Scottish Government’s Digital Directorate is looking to ensure that the data are released on open licence to provide broad and easy access. Work is underway to develop a next generation platform for data sharing.<\/p>\n

Our use of LiDAR data<\/strong><\/p>\n

Maps are one of humanity\u2019s most important inventions, allowing us to understand our environment, our place within it, and plan our activities and movements. The objective for all mapmakers is to enhance their representation of landscapes. There is now a revolution in mapping that can deliver a major step forwards in accuracy and detail, using LiDAR technology. LiDAR uses lasers mounted on special aircraft to boost three-dimensional mapping. The precision of lasers provides a step-change in information, making measurements of height at very fine (centimetre) resolutions, 100 times more precise than Ordnance Survey maps. LiDAR maps the terrain, but also maps objects above the ground surface, such as trees and buildings.<\/p>\n

LiDAR is accurate enough to allow determination over time of the growth of forests, restoration of peatlands, erosion of soils along river channels and coastlines above high water, or construction of buildings, for example.<\/p>\n

The Scottish Government is funding research to help understand and use LiDAR data more effectively, with a focus on environmental and agricultural issues, such as mapping the state of Scotland\u2019s peatlands, woodlands and forests. Such mapping will help determine and support progress towards national climate, tree planting and nature restoration objectives.<\/p>\n

This LiDAR investment can also support businesses, agencies and the public. For instance, LiDAR could be used to support farmers to map biodiversity on their farms by identifying hedgerows, wetlands and trees outside woodlands. LiDAR can identify most precisely where heavy rain will flood fields and where gradients cause vulnerability to erosion or loss of fertiliser into waterways. This knowledge can help farmers to adjust their management, conserving their resources, and protecting the environment.<\/p>\n

A Collaborative Effort<\/strong><\/p>\n

The Scottish Land LiDAR Programme is the result of collaboration across government. The Rural and Environment Science and Analytical Services (RESAS) team and digital teams have worked collaboratively with UK Government Digital Services, who have provided our mechanism for data collection through the Aerial Photography for Great Britain (APGB) Project.<\/p>\n

The programme is funded jointly by the Scottish Government (including Agriculture and Rural Economy, Environment and Forestry, RESAS, Agricultural Reform Programme and Digital), SEPA, FLS, NatureScot, Scottish Water and Scottish Forestry.<\/p>\n
