Airbone Laser Scanning (ALS) is a surveying technique that make use of active optic sensor. It use is rapidly expanding because it makes possible to build Digital Canopy Model (DCM), digital Canopy Model (DCM), Digital Terrain Model (DTM) and Digital Surface Model (DSM) in a more efficient and detailed way than traditional method. It is an important tools in many fields: land planning, hydrology, pollution science, civil engineeting and many other. In forestry, this approach is becoming an important support to prepare topographic mps and to study forest biometric attributes. This thesis deals with the use of ALS for the forest boundary delineation within a provincial forest planning framework, using a CHM and aerial photos.

Abstract
Airbone Laser Scanning (ALS) is a surveying technique that make use of active optic sensor. It use is rapidly expanding because it makes possible to build Digital Canopy Model (DCM), digital Canopy Model (DCM), Digital Terrain Model (DTM) and Digital Surface Model (DSM) in a more efficient and detailed way than traditional method. It is an important tools in many fields: land planning, hydrology, pollution science, civil engineeting and many other. In forestry, this approach is becoming an important support to prepare topographic mps and to study forest biometric attributes. This thesis deals with the use of ALS for the forest boundary delineation within a provincial forest planning framework, using a CHM and aerial photos. A semiautomatic methods was developed and tested in a study area of Trento Province (Northern Italy). Afield surveys was performed to test theaccuracy of the results. The thesis is divided in two chapters: The first deals with forest and mountain plants of Trento Province and with the study area and the definition of forest applied in the thesis; The second describes the method, its results and accuracy test and some concluding remarks.File | Dimensione | Formato | |
