Summary

This dataset contains the percentage of 14 National Land Cover Database (NLCD) land cover classes within the drainage areas of 15 watersheds in Gwinnett County, Georgia from 2001 to 2019. The dataset includes scenes from eight years, 2001, 2004, 2006, 2008, 2011, 2013, 2016, and 2019, which were analyzed using a consistent approach so that they could be used to assess land cover changes. The NLCD dataset is derived from Landsat imagery and has a grid size of 30 meters. The fourteen land cover classes were categorized into eight land cover groups to simplify the presentation of watershed land cover characteristics (1. developed, low intensity; 2. developed, medium intensity; 3. developed, high intensity; 4. developed, open space; 5.

Purpose

The purpose of this dataset is to provide the NLCD land cover class data used to summarize changes in eight defined land cover groups for the 15 Gwinnett County watersheds over the 2001 to 2019 period. Data from these land cover groups were summarized in the U.S. Geological Survey (USGS) Scientific Investigations Report "Hydrology, water-quality, and watershed characteristics in 15 watersheds in Gwinnett County, Georgia, 2002-20". This study is part of a long-term program to monitor and analyze the hydrologic and water-quality conditions of 15 watersheds in Gwinnett County, Georgia by the USGS in cooperation with Gwinnett County Department of Water Resources.
