Computer Usage The students used the Internet to collect sites providing GPS information, download course notes, download homework assignments and exams, download data and support software from the NGS and other sites, and submit solutions to problems via electronic mail. They used word processing software to prepare homework assignments and Trimble Geomatics Office to adjust data, to analyze, and adjust GPS data.
