30m Building Height/Volume of England by Fusing Landsat and Global Elevation Data

The lack of three-dimensional (3D) urban structure information has been a major limiting factor in important urban applications such as population mapping, disaster vulnerability assessment, and climate change adaptation. The 30m England building height and volume data set was produced by fusing of freely available Landsat and global elevation data. Based on an object-based machine learning approach, it is the first freely available data set to provide 30m wall-to-wall coverage of urban structure at the scale of a country. This data set has been validated using Lidar measurements and achieved an RMSE of 1.61 meters for building height and an RMSE of 1,142 cubic meters for building volume.
