The LANDFIRE (LF) Reference Data Base (LFRDB) is a key component of the LF mapping process and contains hundreds of thousands of geo-referenced field plots compiled from a variety of organizations. LF worked in conjunction with NatureServe to create a series of geographically-based "Auto Keys" to create a consistent Existing Vegetation Type (EVT) attribute for each plot.
This assessment was implemented at the end of LF National (LF 1.0.0) to:
- evaluate the quality of the Auto-Keys
- improve the accuracy of the automated EVT assignment
