    • Geospatial data for the Vegetation Mapping Inventory Project of Lassen Volcanic National Park

    Metadata Updated: June 4, 2024

    The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles.

    The APMM provides polygonal data with floristic attributes along with categorical data for cover by vegetation type. The photographic interpretation was based on 1:15,840-scale true-color aerial photography (prints and transparencies) acquired in July and August 2004. The interpreted overlays were orthorectified along with the scanned aerial photography and vectorized using Arc/Info™ (ESRI, Inc.) software. The DCMM produces a raster database from which multiple vector products can be derived to depict the floristics (using any vegetation classification with defined thresholds) and quantitative metrics with estimates of statistical confidence for cover by species and class, quadratic mean diameter of tree stems and crowns by species, trees per acre, fine and coarse woody debris, and other metrics. Two Landsat 5 Thematic Mapper scenes acquired in July and September 2005 were processed with Intergraph® software utilizing all bands except the thermal band. . The APMM mapped 27 Generalized Alliances and seven non-vegetated classes with an overall proportion correct of 72% (based on the most liberal of three accuracy thresholds). The DCMM mapped 29 Generalized Alliances and three non-vegetated classes with on overall proportion correct of 86% (based on the most liberal of three accuracy thresholds).
