AB: Geoprocessing of landuse/landcover, topographical, and meteorological datasets is ubiquitous in the initial set- up of environmental models' applications. Geoprocessing provides parameterized geographic/meteorological information to models, organized per geographic sub-region or in the form of time-series. Environmental models use the summarized information for simulation of past, present or future events of interest. Traditionally, geoprocessing is performed following protocols and methodologies built-in into the environmental models. Each geoprocessing routine is tailored by the model's developers and is not re-usable or transferable to other models. Furthermore, metadata documenting the geoprocessing steps are usually not detailed.
This paper proposes the use of the Geospatial Object Library for Environmental Modeling (GEOLEM) as an alternative or complementary tool for calculating land use, topographical, and meteorological parameters and time-series. GEOLEM has the capability of providing re-usable and transferable geoprocessed information to environmental models. Although this research focuses on the calculation of the geographical parameters and time-series needed by the Hydrological Simulation Program Fortran (HSPF), potential uses of GEOLEM in other environmental modeling frameworks are also addressed. The project area is located in the Saint Louis Bay watershed in the Mississippi Gulf coast. Interferometric Synthetic Aperture Radar (IFSAR) Digital Surface Model (5-m horizontal, 0.01-m vertical resolution), NASA's Shuttle Radar Topography Mission (SRTM) DTED Level 2 (30- m horizontal, 0.01-m vertical), National Elevation Data (NED) (30-m horizontal, 1-m vertical), and USGS DEM (300- m horizontal, 1-m vertical) topographical datasets were used in this research. Additionally, three landuse/landcover datasets were included: Geographic Retrieval and Analysis System (GIRAS), National Land Cover Dataset (NLCD), and NASA's Moderate Resolution Imaging Spectroradiometer (MODIS MOD12Q1). Meteorological time-series produced by NASA's Land Information System (NASA-LIS) were geoprocessed for updating/filling existing meteorological stationīs data. NASA's simulated VIIRS imagery were also included in the study for landuse/lancover characterization and parameterization.
