Spatial survey of urban environments

The paper deals some experimental benchmarks regarding urban environment modelling. The first application has been performed over the small thermal settlement of S. Pellegrino Terme, famous in northern Italy both for the healing waters and for its rich Art Noveau architectural decorations; the second test is the documentation of the religious complex of Dehonians in Albino, a little town close to Bergamo (Italy).The employed techniques, which automatically collected point clouds and created the DSM, are terrestrial laser scanning, with a direct GNSS-RTK geo-referencing, and UAS imagery.
