2020 Systemic Land Cover Data, Upper Mississippi River System (UMRS)

The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) program, through its Long Term Resource Monitoring (LTRM) element, collected aerial imagery of the systemic Upper Mississippi River System (UMRS) during the summer of 2020. A Land Cover/Land Use (LCU) spatial database was developed based on the 2020 aerial imagery, which adds a fourth systemic-wide database to the existing 1989, 2000, and 2010/11 LCU databases. The main purpose of the Land Cover/Land Use (LCU) spatial datasets is for resource managers and researchers to assess and evaluate current (2020) vegetation components and long-term vegetation trends of navigable pools (the stretch of river between locks and dams) and reaches of the UMRS. These pools [...]
