Two Publications on How to Best use Remote Sensing Data at a 1-km scale

Two Publications on How to Best use Remote Sensing Data at a 1-km scale


The NCEAS Environment and Organisms Working Group set about to assemble a state-of-the-art set of environmental layers that incorporate well-known but rarely used measures that have direct links to physiological processes (e.g. water stress, growing season, soil properties, etc.). The team has combined various land-cover variables into a unified, global, high-resolution (1 kilometer) dataset that is available to the public. In addition, they have identified best practices for generating fine resolution maximum daily air temperature datasets. The results of this Working Group have recently appeared in two peer-reviewed publications.

Land-Cover: The most recent manuscript addresses the shortcomings of existing remote sensing-derived land-cover products by generating a global 1-km resolution consensus land-cover product that provides scale-integrated, accuracy-weighted information on a continuous scale. The consensus dataset broadly surpasses any base product the utility for modeling species distributions. The results of their work were recently published in Global Ecology and Biogeography.

Climatic Variables: The second manuscript addresses lack of accurate and spatially contiguous climatic variables at fine temporal and spatial grains. The authors evaluate best practices for generating gridded, one-kilometer resolution, daily maximum air temperature surfaces in a regional context, the state of Oregon, USA. These results were recently published inRemote Sensing.
