Historic map analysis: spatial error in the CA VTM dataset

Kelly, M., K. Ueda and B. Allen-Diaz. 2008. Considerations for ecological reconstruction of historic vegetation: Analysis of the spatial uncertainties in the California Vegetation Type Map dataset. Plant Ecology 194 (1): 37-49

Uncertainty surrounding plot centersWe examine the spatial uncertainties associated with 18,000 vegetation plots in the VTM dataset that has been digitized for use in modern ecological analysis. We examine the relationship between plot location error and basemap year, basemap scale, plot elevation, plot slope, and general plot habitat type. Pdf download. Journal link.
