Advanced Very High Resolution Radiometer Raster Data for Great Basin
Summary
All files can be opened in ArcGIS. (Combination of grid files and shapefiles) brte_gb_av1km: 1 km native resolution AVHRR map for the Great Basin. Methods described in Bradley & Mustard, 2005, Remote Sensing of Environment brte_bg_avhrr: 4 km resolution AVHRR map for the Great Basin in a standard coordinate system projection. Map published in Bradley & Mustard, 2008, Global Change Biology brte_nv_lndst: 90 m resolution (downgraded from 30 m for the sake of space) Landsat map from 2001. Based on data from Eric Peterson (some unpublished, some in E.B. Peterson, 2005, International Journal of Remote Sensing) and calibrated with point data collected by BB in 2004/2005. Only northern Nevada included because southern Nevada maps are sketchy [...]

Based on data from Eric Peterson (some unpublished, some in E.B. Peterson, 2005, International Journal of Remote Sensing) and calibrated with point data collected by BB in 2004/2005. Only northern Nevada included because southern Nevada maps are sketchy - likely confounded by other invasive and native annuals. brte_nv_modis: Unpublished MODIS map based on inter-annual variability between 2005-2002 springs. Map detects 75% of cheatgrass 'presence' points with a 20% false positive rate. (Overall accuracy ~78%)
