Data Import
Generating a digital town model generally requires to import digital data from different sources. This typically concerns the roads, the buildings and the terrain. For each group of objects the geometry, as well as the object data (such as traffic counts, road width, building heights, number of inhabitants) may have different formats which have to be imported into the noise mapping software and also have to be combined. CadnaA offers numerous
import formats enabling to make use of any kind of digital data to generate the final digital town model.
Already when importing data into CadnaA - and this is exactly one mouse click onto the filename - many functionalities to optimize the data and the model can be used. The closed polygons presenting buildings in CadnaA are automatically produced even if the original data consist of many single lines as it is often the case with architectural drawings. Holes inside the building polygons representing backyards are treated correctly. Contour lines extremely detailed can be simplified reducing the number of points because such unnecessary details lengthen the calculation time without gain in accuracy.
