GPS RTK Topographic Procedures

Approved Florida Board of Professional Surveyors and Mappers – Course No. 7592

Course Description:

This correspondence course gives instruction and information regarding Real Time Kinematic Global Positioning System surveying techniques used in the collection of topographic data.  The course teaches skills needed in the practice of this modern surveying and mapping procedure.  The course study materials consist 14 typed pages found in Chapter 9 (GPS Real Time Kinematic Topographic Survey Procedures) of the Department of the Army publication (EM 1110-1-1005) dated January 1, 2007, by the U.S. Army Corps of Engineers entitled “Engineering and Design Control and Topographic Surveying”.    

Course Topics:

· RTK Survey Procedures

· RTK Survey Accuracy

· Site Calibration

· RTK Systems Checks

· Data Collection

Course Objectives:

The objective of “GPS RTK Topographic Procedures” is to provide information that will assist the surveyor in using GPS Real Time Kinematic surveying techniques in preparing topographic surveys.

Evaluation Method:

A ten question written examination will be used to determine if the course objectives have been met.  The student must achieve a minimum of 70 percent correct answers in order to receive Land Pro Seminars’ Continuing Education Credit Certification.
