CIV 256 - Global Positioning Systems for Land Surveying (3 CR.)

Course Description

Introduces principles of satellite-based surveying and presents the Global Positioning System (GPS) as it is utilized in land surveying. Various components of GPS technology are described and techniques, through which GPS technology can be used in land surveys, are presented. Field exercises will be assigned utilizing GPS equipment as part of the laboratory activities. [This course covers the same content as GIS 256. Credit will not be granted for both courses]. Lecture 2 hours. Laboratory 3 hours. Total 5 hours per week.

General Course Purpose

This course introduces students to the Global Positioning System (GPS) and how it can be used in surveying. Students learn about GPS surveying equipment, related field procedures, and analysis of GPS data. Emphasis is on GPS applications related to mapping, engineering and construction projects. This course is primarily aimed at the intermediate to advanced surveying/engineering technicians.

Course Prerequisites/Corequisites

Prerequisite: CIV 171 or Division Approval
