Arroyo-Mora, J. Pablo; Kalacska, Margaret; Soffer, Raymond; Lucanus, Oliver; Løke, Trond; Hernandez, Julio; Adamek, Dennis 2023-11-10 Over the last ten years, the Applied Remote Sensing Laboratory (ARSL, McGill University) in collaboration with the National Research Council of Canada's Flight Research Laboratory (FRL), has been implementing cutting-edge unmanned aerial vehicle (UAV) hyperspectral systems for diverse applications (e.g., biodiversity, subaquatic vegetation, wildfires), with a significant focus on satellite product validation methodologies for northern ecosystems – e.g. peatlands. SRIX4Veg is endorsed by CEOS (Committee on Earth Observation Satellites) and is funded by the European Space Agency (ESA). The ARSL, FRL and Norsk Elektro Optikk HySpex teamed up to participate in the SRIX4VEG: Surface Reflectance Intercomparison Exercise for Vegetation experiment, at the Las Tiesas Experimental Station, Barrax, Spain. This intercomparison experiment included teams from Europe, US and Canada, aiming to develop a protocol for best practices for UAV hyperspectral image acquisition for satellite land product validation within ESA’s Fiducial Reference Measurements for Vegetation (FRM4VEG) project. Here we summarize the imagery acquired by our team during the field campaign at the July 18-22, 2022 field campaign. Meta data includes a description of the imagery acquired under the user-defined methodology. A future update will include metadata for the imagery acquired under the common experiment parameters defined by the organizers.

Pablo; Lucanus, Oliver; Cottrell, Paul; Lehnhart, Taylor 2024-06-11 On March 23, 2024, a handheld LiDAR device (iPhone running Scaniverse) was used to collect 3D scans on a 6.02-meter pregnant adult female Killer Whale (Orcinus orca) and her unborn fetus. These scans were conducted during a live stranding event near Zeballos, B.C., Canada, where the adult female and calf became trapped in a lagoon. Despite efforts to return the adult to the water, she sadly died later in the day. The handheld LiDAR allowed us to capture highly detailed and accurate morphological data of both the adult female and the unborn fetus before the necropsy commenced.

Soffer, Raymond; Arroyo-Mora, J. Pablo; Kalacska, Margaret; Ifimov, Gabriela; Leblanc, George 2022-07-07 The data available consist of airborne hyperspectral imagery acquired for the <i>Mer Bleue Arctic Surrogate Simulation Site (MBASSS) S2/L8 Data Product Validation Project</i> in 2016. MBASSS was a collaborative effort aimed at developing a systematic approach for ongoing assessment and validation of satellite based land information products from Landsat 8 OLI and Sentinel 2 satellites. The airborne systems used for this project were the CASI-1500 and SASI-644 hyperspectral instruments (ITRES Research, Calgary AB) installed in the National Research Council Canada Flight Research Lab (NRC-FRL) Twin Otter aircraft. Standard level 2 processed imagery is provided for download as rasters in ENVI Standard format. Imagery is available from April 20, May 11, May 24 and June 23, 2016 as a set of 12 individual flight lines per date. The imagery has been atmospherically corrected and during the geocorrection process, it has been resampled to 1 m pixel size. Currently CASI and SASI imagery are provided separately. Metadata for each flight line is provided in external ascii ENVI header files (*.hdr) and *.met files. The geocorrected imagery provided with pixel level information including pixel view zenith angle (off Nadir angle), DEM, view azimuth angle, radiance path distance, column and row numbers of pixels in non-geocorrected image file, and relative pixel offset between calculated and assigned pixel location. This information is provided in associated *.nad and *.nad.hdr files.

Kalacska, Margaret; Lamboj, Anton; Lucanus, Oliver; Osei Darko, Patrick; Arroyo-Mora, J. Pablo 2020-06-02 <p>Remote sensing has become an integral and invaluable tool to inform biodiversity conservation and monitoring of habitat degradation and restoration over time. Despite the disproportionately high levels of biodiversity loss in freshwater ecosystems worldwide, ichthyofauna are commonly overlooked in favor of other keystone species. Freshwater fish, as indicators of overall aquatic ecosystem health can also be indicators of larger scale problems within an ecosystem. As a case study with multi-temporal, multi-resolution satellite imagery, we examined deforestation and forest fragmentation around the Atewa Forest Reserve, Ghana. Within small creeks, <i>Limbochromis robertsi</i>, a unique freshwater cichlid with an extremely limited distribution range can be found. Historically, the land cover in the area has undergone substantial deforestation for agriculture and artisanal small-scale mining. In the 1389 km<sup>2</sup> study area we found deforestation accelerated along with increased forest fragmentation in the 2014 – 2017 period (167.4 km<sup>2</sup> of deforestation) with the majority of the forest loss along the river and creek banks due to small-scale mining operations and increased agriculture. Field visits indicated a decrease in the total <i>L. robertsi</i> population by approximately 90% from the early 1990s to 2018. Its<i> </i>distribution has been reduced to higher elevations by anthropogenic habitat barriers at low elevations and the presence of predatory species. Loss of Riparian forest through land use and cover change to mining and agriculture contributes to the habitat degradation for these endemic species. The fine spatial and temporal scale studies required to assess habitat characteristics is not captured by global or continental scale datasets.</p>
