Land use and land cover (LULC) maps for the United States are usually produced by the Multi-Resolution Land Characteristics (MRLC) Consortium. The National Land Cover Database (NLCD) for the years 1991, 2001, 2006, and 2011 are readily available. However, the 2016 dataset is yet to be released. Datasets from the NLCD are generally Landsat-based, hence their spatial resolution is 30m. At the moment, most research with a LULC component, relies on the 2011 NLCD dataset despite being coarse (30m) and outdated (7 years old). In this study, the European Space Agency’s (ESA) Sentinel-2 imagery with 13 spectral bands ranging from visible to shortwave infrared, and spatial resolutions of 10-60m, was used to develop a land use and land cover map of the Mill Creek watershed in Northeast Ohio. The watershed, a tributary of the Mahoning River, covers an area approximately 78.4 square miles and has mixed land uses. Results from this study illustrates the importance of Sentinel-2 data in supplementing NLCD.
