Summary

This set of non-spatial tables provides a detailed link (crosswalk) between the general classification within Long Term Resource Monitoring (LTRM) land cover/use (LCU) geospatial layers and the U.S. National Vegetation Classification (USNVC), current as of April 2017. The Upper Mississippi River Restoration (UMRR) Program’s LTRM element has produced LCU data over the past three decades consisting of geospatial layers (maps) showing locations of vegetation and developed lands within the Upper Mississippi River System (UMRS). The LCU data layers contain a classification of 31 general classes specifically developed to meet needs and objectives of the LTRM element of the UMRR Program. Because the LTRM classification is consistently applied [...]

Purpose

This classification crosswalk provides scientists and resource managers who use the LCU data layers access to an up-to-date USNVC representation for each of the 31 general classes. With the crosswalk to USNVC types, LTRM LCU data layers meet an FGDC standard that promotes consistency of vegetation classification products among agencies within the federal government that might use the USNVC. Furthermore, having the crosswalk product as a stand-alone table allows for future updates that can link to existing LTRM data layers with minimal modification.
