Geodetic Reference Datums and Local Coordinate Systems
Approved Florida Board of Professional Surveyors and Mappers – Course No. 7587
This correspondence course provides guidance on geodetic reference datums, coordinate systems, and local horizontal and vertical reference systems that are used to georeference construction and civil works projects. Use of State Plane Coordinate Systems (SPCS) is covered in detail, Transformations between datums and coordinate systems are discussed. The course teaches skills needed in the practice of surveying and mapping. The course is based on Chapter 5 (Geodetic Reference Datums and Local Coordinate Systems) 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".
Transformations and Conversions
The objective of "Geodetic Reference Datums and Local Coordinate Systems HS" is to provide information that will assist the surveyor in using and understanding geodetic reference datums and local coordinate systems for use in surveying and mapping applications.
A 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 continuing education credit.
