The aerial survey was conducted to collect LiDAR data with a Nominal Pulse Density (NPD) of 4ppsm (Pulses per Square Metre). The NPD is the ratio of the number of first-return pulses to the area of the project. The ground survey was conducted over seven days, beginning August 26, 2016 and ending March 20, 2017, using a Leica GS14 RTK system. The ground survey data collected was processed using Leica Geo Office. The aerial survey was completed over 8 flights between August 3, 2016 and August 21, 2016 using a Leica ALS70-HP LiDAR sensor and a Leica IPAS CUS6 airborne GPS/IMU aboard a PA-31 Piper Navajo aircraft. The ALS70-HP collects an unlimited number of return pulse with intensity data on the first three returns.

Lidar is acquired on Aug 3, 6, 7, 8, 14, 16, 17, 21, 2016, as part of another spec project. Lidar is calibrated with NAD83 (CSRS) and CGVD28 datum using UTM 14 North projection and is classified. The classified data was used to create the DEM using the following classes: 2 (all ground features that exist). Dem was created at a 1m resoultion and then exported out as a Geotiff with 32 bit floating elevations. Images were cut into tiles based on the lidar index .
