Abstract: The proposed Arctic and Boreal Vulnerability Experiment (ABoVE) will conduct multi-disciplinary studies to explore and quantify the linkages between all of the individual components of the ecosystem. One common thread identified in the final report for the scoping study for ABoVE is the need for maps of the location, extent and dynamics of surface ... [more]

Product Title:  ABoVE: Surface Water Extent, Boreal and Tundra Regions, North America, 1991-2011
Description:  This data set provides the location and extent of surface water (open water not including vegetated wetlands) for the entire Boreal and Tundra regions of North America for three epochs, centered on 1991, 2001, and 2011. Each of the products were generated with at least three years of ice-free Landsat imagery. The data are at 30-m resolution and were derived from time series of Landsat 4 and 5 Thematic Mapper (TM) data and Landsat 7 Enhanced Thematic Mapper (ETM+) covering all of Alaska and all provinces of Canada. The overall goal was to generate a map of the nominal extent of water for a given epoch, where nominal is neither the maximum nor the minimum but rather a representative extent for that time period.
To aid the use of the product a quality assurance (QA) layer was generated for each data file (map). These data provide additional information regarding the source of values in the water extent maps and the confidence in the extent value determined by the number of water image observations in the probability of water.

There are 78 data files in GeoTIFF (.tif) format with this data set. This includes 39 surface water body data files and 39 QA files, one for each of the data files.
Expected Users:  research scientists, others interested in surface water processes
