Low-Altitude Photographic Transects of the Arctic Network of National Park Units and Selawik National Wildlife Refuge, Alaska, July 2013

摘要

Photography of land-cover conditions in arctic and boreal regions of Alaska has proven to be of great value for analyzing landscape changes from various local-to-regional causes (Swanson and Hill, 2010; Swanson 2012a, 2012b; Necsoiu and others, 2013). For example, a systematic 20-km grid of aerial photographs (Swanson, 2013) has provided information for estimating rates and causes of changes in land-cover types (vegetation, water). These estimates of transitional rates have been used in projecting potential effects of climate change on future land cover and implications for wildlife habitat throughout a large arctic and boreal region of northwest Alaska (DeGange and others, 2013). This project was initiated to complement the existing photographic databases by providing a set of high-resolution, natural-light images in continuous coverage along flight transects within the study area of northwest Alaska addressed by DeGange and others (2013).
