GeoTemple Datasets

About GeoTemple

GeoTEMPLE is designed to be a repository of functional geospatial databases supporting nation-wide applications of simulation models for the water quality assessment and the implementation of agricultural management and conservation practices.

Soil Databases

US-ModSoilParms-TEMPLE are locally seamless, multi-scale geodatabases, functionally storing soil-spatial units and soil hydraulic, physical, and chemical parameters for three agriculture management simulation models, SWAT, APEX, and ALMANAC. The United States coverage organized as a framework of 22 (21 at lower resolution) nested and hydrologically-ordered regional geographic databases with internal spatial segmentation drainage-defined at a conveniently manageable tile (Watershed Boundary Dataset’s, WBD, 8-digit Subbasin) level. Spatial features are stored in multiple formats (raster and vector) and resolutions (10-meter and 30-meter), while being in direct relationship with the table of attributes storing the models’ parameters.

A significant number of former parameter voids, determined by the local incompleteness of the source datasets, were filled using a methodology leveraging upon the hierarchy of the Soil Taxonomy information and the geographic location of the gaps.

The functionality of each geographic database was extended by adding customized Python-based tools (toolset part of the GeoTEMPLE tool box), which streamline the incorporation into geoprocessing workflows, the aggregation and extraction of data sets, and finally the export to other model support software user environments. These tools are attached and conveniently distributed along with detailed metadata documentation within each of the developed regional geographic databases. The system hosting this framework is developed using a proprietary software format (ESRI® File Geodatabase), however, a companion version of the framework of 8-digit tiles is also developed and provided using openly accessible formats.
