Indigenous peoples as sentinels of change in human‐wildlife relationships: Conservation status of mountain goats in Kitasoo Xai'xais territory and beyond

Conservation Science and Practice, 2022
Local people can act as sentinels for change, especially for wildlife populations not monitored by centralized governments. Responding to concern expressed by the Kitasoo Xai'xais (KX) First Nation over a decline in mountain goat (Oreamnos americanus ...

Evaluation of Semantic Segmentation Methods for Land Use with Spectral Imaging Using Sentinel-2 and PNOA Imagery

Remote Sensing, 2021
Land use classification using aerial imagery can be complex. Characteristics such as ground sampling distance, resolution, number of bands and the information these bands convey are the keys to its accuracy. Random Forest is the most widely used approach
