CoordinatesNJ PLS Board Approved Course

Jan Van Sickle, P.L.S.

This course discusses the processes and procedures involved in handling coordinates in surveying, mapping and GIS. Since most, if not all, of these processes and procedures are now computerized the need for understanding them is not always immediately apparent. However, without that understanding the user can be led astray, quickly and disastrously by the same computer programs that make coordinate manipulation so automatic. Incorrect coordinates can, at a stroke, dramatically erode confidence in an entire body of work.

The development of GPS and the almost universal use of this utility also brings and understanding of coordinates to the fore. When GPS is used as a measurement system it is not possible to avoid geodetic considerations.

This course not only provides the foundation of basic geodesy, it also explains how those ideas are pertinent to everyday work. There is no complex mathematics in this course. The relationships that are incorporated for the illustration of the ideas discussed. Those ideas, those concepts, are the heart of the course.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

This PDH online course is approved by NJ LS Board.
