Apoyo técnico e investigativo para la cuantificación de biomasa y stock de carbono, utilizando datos LiDAR de alta densidad, para parcelas en el departamento del Chocó, caso de estudio: Medio Baudó y Bajo Baudó

Abstract

The present work aims to adapt a methodology for the quantification of biomass and carbon stock in high resolution, for 3 plots located between the municipalities of Bajo Baudó and Medio Baudó in the department of Chocó, generating the Digital Terrain Model (DTM) and the Digital Surface Model (DSM) through LiDAR data modeling. Optical remote sensing technique, which uses laser pulses to calculate the limit distance between the sensor and the target, and according to this obtain heights and values in X and Y, in addition to using secondary information to generate elevation models. The volume of biomass for each of the plots under study was obtained through the development of vegetation height models, based on the generation of digital terrain models (DTM) and digital surface models (DSM), which were generated based on classified LiDAR point clouds. A validation of the models was carried out and the carbon and CO2 equivalent for the AOIs was calculated from the Corine Land Cover map at a scale of 100,000 for Colombia. The biomass and CO2 data obtained are approximate values, since the model was not calibrated with dasometric data from the study area. The scope of the project provides a first phase of characterization of the area of interest, to know the biomass and carbon stock data that the study areas harbor and to propose the collection of field data to adjust the model.
