Summary
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. While a crosswalk was used to update the 1989 LCU database (originally developed using a different classification system), the 2000, 2010/11, and 2020 LCU databases share the same classification, making them directly comparable from a classification standpoint. Furthermore, protocols in addition to [...]
Summary
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. While a crosswalk was used to update the 1989 LCU database (originally developed using a different classification system), the 2000, 2010/11, and 2020 LCU databases share the same classification, making them directly comparable from a classification standpoint. Furthermore, protocols in addition to standard mapping methods were explored to increase the utility of the 2020 UMRS LCU database for research monitoring when compared to the 2010/11 UMRS LCU database. These map protocols aimed to reflect “true” spatial and temporal changes in vegetation polygons and classification rather than changes due to differences in image interpretation or image spatial positioning.

Purpose
The objective is to develop and distribute Land Cover/Land Use (LCU) spatial datasets and orthoimages (frames and mosaics) from aerial imagery collected in summer of 2020 of the systemic Upper Mississippi River System (UMRS) of navigable pools (the stretch of river between locks and dams) and reaches. These pools and reaches include Pools 1 through 26, the Open River Reach, the entire Illinois River, and the navigable portions of the Minnesota, St. Croix, and Kaskaskia Rivers. The data products are primarily intended for resource managers and researchers to assess and evaluate current (2020) vegetation components and long-term vegetation trends within the UMRS.
