A computerized method for compiling and reducing land use data for hydrologic computer model simulation was developed. The technique was developed for use on an IBM compatible PC. The purpose of the method was to provide a tool for handling large amounts of land use data accurately, efficiently and cost effectively for hydrologic modeling using the Hydrologic Simulation Program (HSPF) for large watersheds. A secondary purpose of the method was to provide a land cover data base that could be easily updated for ready use in future computer model simulations. This method was developed as part of the hydrologic and hydraulic data collection effort for the DuPage County, Illinois Stormwater Management Program. The design of the method was based upon existing land use data and commercially available software. Land use data consisted of ortho and aerial photographs, topographic mapping and storm sewer atlases. Commercially available software consisted of AUTOCAD 10, DCA, dBASE IV and HSPF. Specialized software routines were developed to transfer and format files between commercial software.
