Assessing the accuracy of georeferenced landcover data derived from oblique imagery using machine learning

Autor: James Tricker, Claire Wright, Spencer Rose, Jeanine Rhemtulla, Trevor Lantz, Eric Higgs

Publikováno v: Remote Sensing in Ecology and Conservation, Vol 10, Iss 3, Pp 401-415 (2024)

Abstract Repeat photography offers distinctive insights into ecological change, with ground‐based oblique photographs often predating early aerial images by decades. However, the oblique angle of the photographs presents challenges for extracting a

Autor: Brittany Main, Luke Copland, Braden Smeda, Will Kochtitzky, Sergey Samsonov, Jonathan Dudley, Mark Skidmore, Christine Dow, Wesley Van Wychen, Dorota Medrzycka, Eric Higgs, Laurent Mingo

Publikováno v: Journal of Glaciology, Vol 69, Pp 936-952 (2023)

Links between proglacial lakes and glacier dynamics are poorly understood but are necessary to predict how mountain glaciers will react to a warmer, wetter climate, where such lakes are expected to increase both in number and volume. Here, we examine

Weather Awareness: On the Lookout for Wildfire in the Canadian Rocky Mountains

Autor: Kristen Anne Walsh, Mary Sanseverino, Eric Higgs

Publikováno v: Mountain Research and Development, Vol 37, Iss 4, Pp 494-501 (2017)

Mountains are crucial places in which to observe, experience, and learn about rapid weather and climate shifts, felt to varying degrees in different contexts. Fire lookout observers, immersed in the mountain environments of Alberta, Canada, for 5 to

Forest closure and encroachment at the grassland interface: a century‐scale analysis using oblique repeat photography

Autor: Christopher A. Stockdale, S. Ellen Macdonald, Eric Higgs

Publikováno v: Ecosphere, Vol 10, Iss 6, Pp n/a-n/a (2019)

Abstract We used repeat oblique photography to quantify and determine the drivers of vegetation change, particularly forest closure and encroachment, in the Rocky Mountains of southern Alberta, Canada, from the beginning of the twentieth century to t
