openly accessible building height maps covering the whole China remain sorely limited, particularly for spatially informed data. Here we developed a 1 km × 1 km resolution building height dataset across
Here, we proposed an approach for extracting building height by combining Google Earth Satellite (GES) images and ICESat-2 photons. Building and shadow instances were first extracted using a U-Net deep learning framework. Based on the building height annotations retrieved from ICESat-2 photons, ...
which move and level the soil, and road rollers, which compact the roadbed. The construction of embankments exceeding 2 m in height involves the use of more basic machines, such as scrapers, power graders, and rollers. Earthmoving involves the use of excavators, trucks, and transport carts....
We trained machine learning regression models with highly accurate building height information from several 3D building models. The novelty of this method lies in the very fine resolution yet large spatial extent to which it can be applied, as well as in the use of building shadows in optical ...

The HR optical images (1 m/pixel) are collected from the Google Earth imagery. The images contained three bands of red, green, and blue. The building height LiDAR (10 m/pixel) is from the Chinese building height estimate dataset (CNBH-10 m). The nighttime-light data (10 m/pixel) are...
