High-resolution terrain modelling - LIDAR
(contact address David García)
High-resolution terrain modelling requires of remote sensing techniques, both Lidar technique to terrestrial photogrammetric, aerial or satellites image are used on the Institut de Recerca Geomodels. Infrastructure available at the Institut:
LIDAR
In September 2005 the Institut acquired a Lidar equipment constituted by:
-
✓Terrestrial Laser Scanner model ILRIS-3D Optech Inc.
-
✓Differential GPS, receiver model GB-1000 and antenna PG-A1 W/GP TOPCON company, for the georeferencing data acquired by laser scanner.
-
✓Digital camera CANON 40D (12M Pixels). With calibrated lens for creating photo-realistic models from laser scanner data.
-
✓Team batteries and electric generator as energy source of the equipment
Associated software
-
✓Data acquired are processated by commercial software PolyWorks (Innovmetric Software Inc.).
-
✓Software developed at the Geomodels Institut to support methodologies and workflows
