ATKIS – bDOM20

Image-based Digital Surface Models (BDOM) depict the Earth’s surface and the objects on it at the time the aerial images are taken, such as vegetation and buildings. From the correlation of oriented aerial images (OLB) and the modelling of the resulting point clouds is created a regular grid. Due to the procedure, the BDOM may contain gaps and outliers, which may be filled up by interpolation or by appropriate methods. to be eliminated. Each raster element can also have attributes (e.g. color information such as RGBI). Another attribute describes whether the height value of a raster element has been calculated from the image correlation. All points that have not been calculated via image correlation will be marked as synthetically generated points. Source: Product Standard for Image-Based Digital Surface Models (BDOM) AdV
