ACO Project# 20-3016-00
Andrew Martindale and Susan Marsden have requested 7 areas of interest (AOI) in Northern BC to derive high-resolution terrain models of key archaeological sites. The focus for this project is to provide detailed bare earth models to help identify archaeology sites and allow the researchers to map traditional land use areas. The project was successfully flown on July 30th, 2020. Weather throughout BC in 2020 pushed many acquisitions back, and thus we were forced to acquire this data in summer rather than the spring.
The project took place over 7 areas of interest with a total size of 50.13 km2. These sites are located along highway 37, distributed around Cranberry Junction on the Nass River, British Columbia.
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).
