An interactive, computer-based management system for hydrologic data

An automated system has been developed to digitize the continuous traces generated by strip chart recorders. The system is comprised of an electronic digitizer, computer terminal, mainframe computer, and custom designed software. The digitizer is connected to a computer terminal with a cassette tape operating in local mode when a chart is being digitized. After digitization is completed, an interactive processing system consisting of a system controller and a series of Fortran programs is accessed to perform various data management, data error diagnostics, data reduction, data summary, and graphics functions.
