LIDAR rilievo 2006/2007/2008 (link to download service)
Description
Link to the download service of the LIDAR survey of the SIAT of the Autonomous Province of Trento which consists of the following products:
* Digital Surface Model (DSM) : is the regular grid derived from the DG, properly filtered, resampled and orthometric to represent the trend of the surfaces (first pulse), with a pitch of 1x1 meter (type 1 areas) and 2x2 meters (type 2 and 3 areas); the expected delivery format is the ascii-grid of Arc/info.
* Digital terrain model (DTM): is the regular grid derived from the DG, properly filtered, resampled and orthometric to represent the trend of the ground (last pulse), with a pitch of 1x1 meter (type 1 areas) and 2x2 meters (type 2 and 3 areas); the expected delivery format is the ascii-grid of Arc/info.
* The raw data (DG) : It is only given on specific request. It is voluminous and has documentary and design support purposes. In fact, having appropriate skills and programs (e.g. Microstation-Terrascan) it is possible to carry out very effective detailed classifications and designs. It represents the set of all the points detected, not filtered or processed (and, therefore, not tested); collected in ASCII files (*.ALL – text version of the proprietary format *.LAS) or *.LAS. The path depends on the type of sensor, which, however, provides for each point at least the type of pulse (first, last), the planimetric coordinates UTM-WGS84, the ellipsoidic altitude and the relative reflectivity heat.
