Service Description:

 This 2025 Height Map is a height map raster featuring a 1sqm resolution. It is a normalised Digital Surface Model (nDSM) that was derived by subtracting the 2025 1m DEM from the 2025 1m DSM, to give the heights of buildings and trees above the ground surface. The high resolution does create noise within the dataset. However, the overlay of the corresponding year's aerial imagery or the building footprint polygons and tree canopy polygons will enable good measurements. Heights less than 2m are excluded from the dataset.
