LiDAR 2022

Listed in vancouver

Description

LiDAR (Light Detection and Ranging) data of the City of Vancouver and UBC Endowment Lands with an Area of Interest (AOI) covering a total of 134 square kilometers.​ Data products includes a classification that defines "bare earth" ground surface, water and of the upper most surface defined by vegetation cover, buildings and other structures. Data access Each of the 181 polygons on the map or rows in the table provides corresponding link to the data in LAS format (zipped, file sizes range from 16.45MB to 2.74GB).

Attributes Point data was classified as: Unclassified; Bare-earth and low grass; Low vegetation (height <2m); High vegetation (height >2m); Water; Buildings; Other; and Noise (noise points, blunders, outliners, etc) Note ​The 2022 LiDAR data is being utilized for initiatives including land management, planning, hazard assessment, (e.g. floods, landslides, lava flows, and tsunamis), urban forestry, storm drainage, and watershed analysis.
