Fraser River Airborne Surveys - 2020 - Airborne Coastal Observatory

2020 Fraser River Airborne Surveys ACO Project# 20 - 3022; 3023; 3024; 3026; 3027; and 3028 Airborne Lidar and Imagery data continued to be collected by the ACO in 2020, in partnership with Dr. Jeremy Venditti (SFU) and Dr. Brian Menounos (UNBC, Hakai Institute). The goal of this data is to inventory and characterize the terrain throughout the Fraser River system to look at contemporary and historical landslide impact on flow dynamics, fish migration, and genetics of Fraser River Salmon. This work was underscored on November 1st, 2018 by the Big Bar Landslide, which partly blocked the Fraser River, creating a hydraulic barrier to salmon passage at moderate to high flows and significantly impeded salmon migration to the upper Fraser Basin. 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). Sensors and instrument breakdown: Inertial Navigation System: Manufacturer: Applanix (Canada), IMU Model: POS AV 510 IMAR, GNSS Model: Trimble AV39. Laser sensor: Riegl LMS-Q 780 long-range airborne laser scanner. Point density ranges per project and landscape from 1-12 points per square meter. Aerial cameras: two fully integrated Phaseone Industrial iXU-RS1000 medium format cameras, resolution: 100MP, lens: 50mm f/4.0 Rodenstock. Hyperspectral Sensor: manufacturer: Specim, model: AisaFENIX 384, spectral range: 380 - 2500 nm
