DuPage County, Illinois, has initiated a county-wide stormwater management program for planning and flood mitigation purposes. Field data with horizontal and vertical control are obtained by a total station electronic distance meter (TSEDM) and are recorded on an electronic data recorder (EDR). Field data are processed in the office to obtain elevation and coordinate data using a microcomputer. Processed data are computer plotted in plan and section views for verification. Final reduced data are recorded on diskettes for use in the County's Hydrologic Information Program (HIP) and computer assisted design and drafting (CADD) mapping operations.
