Topographic humidity index from LiDAR

Topographic humidity index from LiDAR __The link: * Access the data directory* is available in the section*Dataset description sheets; Additional information*__. As part of the provincial LiDAR sensor data acquisition project, a topographic humidity index or *Topographic Wetness Index* (TWI) was produced from the digital terrain model derived from aerial LiDAR (*Light Detection and Ranging*). The matrix layers thus produced provide information on the potential for water accumulation on the territory as a function of the slope and accumulation at a given pixel.**This third party metadata element was translated using an automated translation tool (Amazon Translate).** 2025-05-01 Government and Municipalities of Québec inventaires.forestiers@mrnf.gouv.qc.ca Form DescriptorsNature and EnvironmentScience and Technology Download linksCSV https://diffusion.mffp.gouv.qc.ca/Diffusion/DonneeGratuite/Foret/IMAGERIE/Produits_derives_LiDAR/Hydrographie/Indice_humidite_topographique/3-Donnees/csv/url_twi.csv Open forestHTML https://www.foretouverte.gouv.qc.ca/?context=_lidar&zoom=13¢er=-71.88397,46.90662&invisiblelayers=*&visiblelayers=ad4e43d84410e7c0316cc9f70c1f2a4f,1da64ddfeaf23710b8a9ad95133fb5d8 Open forestHTML https://www.foretouverte.gouv.qc.ca/?context=_telechargement&zoom=6¢er=-72.40234,48.23403&invisiblelayers=*&visiblelayers=3d0ed3b632e4bd6416316c614af54852,1da64ddfeaf23710b8a9ad95133fb5d8 Video clip on the topographic humidity index from LiDARHTML https://youtu.be/rkIWhMFTYH8 Web mapping serviceHTML https://geoegl.msp.gouv.qc.ca/ws/mffpecofor.fcgi?
