Brian Menounos’ Research group at UNBC, along with Hakai Geospatial, flew Lidar and Imagery east of Lillooet over 3 days in 2019 (July 13th & 22nd, and August 13th 2019). Re-flights were required in 2020 to help remove data noise and low point density.
The project took place in 2019, and again in 2020 for reflights, within a 315 km2 area east of Lillooet, BC.
Below is a brief overview of the Airborne Coastal Observatory (ACO) and the type of data collected. For more information on post processing, data quality assurance, software used, and summary of results please contact data@hakai.org
The ACO is an aerial remote sensing platform used by the Hakai Institute to survey landscapes in detail. A Piper Navajo aircraft carries an array of integrated airborne mapping sensors installed to collect data in concert. The aircraft is operated and maintained by Kisik Aerial Surveys (Delta, BC).
Data products available:
Lidar data (LAZ)- classified point cloud – digital surface model – digital terrain model.
Image data (TIFF) – 4 band orthophotos – RGB & NIR.
Hyperspectral data (not always captured).
A detailed project report with the summary of acquisition, processing, and overall hardware / software is available (PDF).
