How does 3D visualisation work
Based on the performed aerial photography it is possible to photogrammetrically locate 3D models of building and build-up areas. Stereoscopic evaluation enables the location of spatial shapes using a special tool on objects with details corresponding to the scale of the images (height of the flight over the terrain).
The headstone of the 3D city model is the model of the build-up area, which can swell to different volumes of complexity according to the intention of the customer. We can divide the building models into three groups according to the complexity of the detail and the way of modelling. Those three are: the block model (without roof modelling), urban model (with roof modelling) and detailed model (measurement of objects on roof, placing according to groundplots, greenery measurement etc.).
We can measure and process a whole line of geographic data out of the aerial photography. This data can be visualised via 3D models. That is why we have introduced GeoShow3D into our portfolio that can clearly visualise this information.
The digital terrain model, on which various vector and raster layers are "placed", serves as the basis for the visualisation. The 3D orthophotomap, together with the 3D model of buildings or urban build-up area, appears very real.
Index points are placed into the created 3D model of scenery or of the built-up area. Any multimedial information - like pictures, video, photographs, text documents, cross references to www pages etc - can be added to these index points. For indivdual browsing and movement through the scenery (city), we use predefined or on-line controlled transits over the scenery.
