Once we had developed the list of potential cross-boundary resource conflicts summarized in table 1 we identified and harvested corresponding geospatial data from the following readily available data sources:
- “Streets” GIS layer, ESRI (Economic and Social Research Institute) Map and Data DVD, dated 2005.

Many of these data sources needed to be used in combination to derive useful information for the resource conflict analysis. For example, the NPScape landscape dynamics monitoring project supplied roads data for use in conjunction with National Land Cover data to determine roadless natural areas. Likewise, NPScape data coupled with National Hydrography Data Sets allowed us to delineate upstream watersheds. We combined STATSGO soils data and digital elevation models with the logic of BLM’s Mojave and Central Basin and Range Rapid Ecoregional Assessments (REAs) to obtain wind and water erosion potential. U.S. Fish and Wildlife Service wetlands and critical habitat for threatened and endangered species were used to identify habitats of concern. We evaluated habitat quality and landscape connectivity through data from two research-based Naturalness and Landscape Permeability data sets. The Protected Areas Database of the United States facilitated our understanding of landownership of various protected areas. Finally, we performed a GIS analysis of potential visual resource impairments that included ambient light pollution measurements from a nighttime lights data set.
