Urban Atlas - Building Height 2012 (raster), Apr. 2018
A 10m high resolution raster layer containing height information is generated for core urban areas of selected cities (capitals in EU28 + EFTA) as part of the Urban atlas. Height information is based on IRS-P5 stereo images and derived datasets like the digital surface model, the digital terrain model and the normalized DSM.
Origine de la donnée :
This product is generated based on IRS-P5 stereo images acquired as close as possible to the defined reference year. Based on these stereo images a digital surface model is generated. Afterwards a digital terrain model is derived from the DSM with different filter algorithms and the assistance of Urban Atlas 2012 datasets. The calculation of the normalized DSM is done by a simple subtraction of the DTM from the DSM. The final product is then clipped based on UA 2012 building blocks and fully quality controlled.
