These data were compiled to compare the ability of matched filtering (MF) and linear spectral mixture analysis (LSMA) to map isolated wetland sites using Landsat 5 Thematic Mapper (TM) and Landsat 8 Operational Land Imager (OLI) data. We analyzed 81 stock ponds corresponding to a 2007 Landsat 5 image and 73 sites corresponding to a 2014 Landsat 8 image in southern Arizona and northern Sonora, Mexico, with ponds ranging from completely dry to ~17,000 m2 surface water. Both Landsat images we used were Tier 1 Level-1 terrain corrected scenes acquired from Earth Explorer (, which were provided as individual bands represented by digital numbers (DNs). The inundation extent of stock ponds in the San Rafael [...]

The purpose of these data are to detect and estimate surface water area of stock ponds in southern Arizona, USA and northern Sonora, Mexico. These water bodies can be difficult to locate, especially in areas were little is known. A full (linear spectral mixture analysis; LSMA) and partial (matched filtering; MF) spectral unmixing algorithm was applied to a 2007 Landsat 5 and a 2014 Landsat 8 satellite image to determine the ability of a time-intensive (i.e., more spectral input; LSMA) vs. a more efficient (less spectral input; MF) spectral unmixing approach to detect and estimate surface water area of stock ponds in this area.
