For the update of your cartography, you can identify and detected changes in the buildings of the properties (based on a record of volumetric changes), for that you will need information acquired with a correct density of points, which allows you to:
Detect new buildings in obsolete identified cartographies or identify illegal constructions. Also you can detect changes in constructions (buildings). This is equivalent to an update of the cartography.
Building height maps, zonal statistics, building type density, etc.
2D or 3D model of the study area with details of homes, neighborhoods, roads, sectors.
Association of drawing surveys with geodatabase of nomenclature.
Digital terrain model (DTM), Digital surface model (DSM), Vegetation height model (MAV), Level Contours and RGB and NIR orthophoto.
