3D Buildings Dataset is GeoActio highest resolution database, addressed to calculations in high density areas where the best accuracy of predictions are required. This dataset includes a layer representing all the buildings of the area of interest, including the height information of every building. 3D modelling enables accurate simulations. 3D Building Dataset is used for micro-level calculations such as indoors coverage, optimum base station parameterization (tilt, azimuth, power, etc.), frequency planning (spectrum management), interference thresholds, etc.
