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 7KB to 950MB). 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)​ Data currency Aerial LiDAR was acquired on August 27th and August 28th, 2018 and is ​current as of those dates.​ Data accuracy The LiDAR data is positioned with an average density of 30 points per square metre Sidelap: minimum of 60% in north-south and east-west directions Vertical accuracy: 0.18 metre (95% confidence level) Horizontal accuracy: 0.36 metre (95% confidence level Coordinate system The map of grid cells on this portal is in WGS 84 but the LiDAR data in the LAS files are in the following coordinate system: Projection: UTM Zone 10 (Central Meridian 123 West) Hz Datum: NAD 83 (CSRS) 4.0.0.BC.1.GVRD Vertical Datum: CGVD28GVRD Metro Vancouver Geoid (HTMVBC00_Abbbyn.zip) Websites for further information ​ City boundary dataset ​
