Explanation: Point cloud at a minimum scale of 1:1000. Processed with manual editing. Ellipsoidal elevation.

Statement: Airborne LIDAR of 347 flight lines between 02-02-2005 and 25-05-2005 carriying an Optech ALTM 3025 sensor. The orientation and trajectories of the sensor are tied to the GPS Network of Gipuzkoa using Applanix POSGPS and TerraMatch software. And subsequent adjustment by means of 45 GPS control points in flat areas. The average density obtained is 1 point/m² and the vertical accuracy is 0.5 m. RMS. The lidar points have been automatically and manually classified using Terrascan and TerraModeler software. It is distributed by laz files (Las 1.0 compressed) in 1 x 1 km grids containing for each point: x, y, z, intensity and classification.
