The Texas Parks and Wildlife Department, in cooperation with private, state, and federal partners, has produced a new land classification map for Texas, based on the NatureServe Ecological System Classification System as described by Comer (2003). Mapping Sub-systems were identified using ecological systems as a starting point. Data was collected in the field and from aerial photography to implement a supervised classification. This land cover data was combined with ecoregions, SSURGO soils, DEM-based variables, and hydrology to help interpret the ecological meaning of final mapping targets. Improved thematic and spatial resolution was achieved using a decision tree classifier with both remotely sensed and abiotic...
