Microcomputer software was developed to digitize, filter, and view data from analog charts of gate operation and water level before being transmitted to a mainframe computer for data base archival. Digitized information is controlled by an IBM-XT microcomputer which is in real time communication with a Summagraphics ID-RS232 digitizer. Software prompts request recorder location, date, and time information. Five keywords initiate appropriate actions to be performed by the digitizer operator. Error processing indicates incorrect actions and provides instructions. For efficient storage of digitized data on diskette, a linear interpolation 'smashing algorithm' is used as a filtering technique to delete unnecessary data.
