Datasets related to crop residue, irrigation, and shortwave infra-red (SWIR) spectral reflectance, Talbot County, MD, May 2015 This posting contains field and satellite data collected in support of the scientific manuscript "Improved crop residue cover estimates by coupling spectral indices for residue and moisture." Quemada, M., W.D. Hively, C.S. Daughtry, B.T. Lamb, and J. Shermeyer. In review by Remote Sensing of Environment. In this study, field data were collected on May 15, 2015 and paired with reflectance data collected May 14th 2015. The manuscript compares portions of agricultural fields that were irrigated the day of imagery acquisitions with portions of the same fields not yet irrigated, using the contrast to derive a moisture correction algorithm for determination of percent crop residue cover. The data publication contains...

Raw and corrected water quality data was collected from the NWIS database for the corresponding dates of Landsat 8 overpasses of all three sites. Calculations and functions from the Landsat bands were compared, such as band ratios and power functions were calculated and compared against the corrected data for Colored Dissolved Organic Matter. These...

Each polygon is representative of the LULC for a specific year within 500-foot buffered watersheds. Watershed boundaries for Cabin Branch (CB), Crystal Rock (CR), Soper Branch (SB), Tributary 104 (T104), and Tributary 109 (T109) were derived using USGS topographic maps while Ten Mile Creek (TMC) was derived using Montgomery County, Maryland LiDAR data. The Habitat Digitizer Extension add-in from NOAA for ArcMap was used to customize a hierarchical classification scheme to attribute polygons delineated...
