Geodesy and Global Positioning System

Links to other pages:

Earth Rotation. Paper by Jos Verheijen describing the principles of earth rotation.

Ellipse demonstration. Java applet showing the geometry of the ellipse. Requires Java 1.1 or better.

Grids and Datums. This is a link to the columns written by Clifford J. Mugnier, CP, CMS that appear almost monthly in the journal Photogrammetric Engineering and Remote Sensing. Each column discusses the nature of datums and grids in a particular country.

Mike Craymer's On-Line Geodesy Resources This site contains a myriad of links related to geodesy and GPS, as well as other topics. One of the nice thing in this site is his Table of Contents in Geodesy page with the table of contents of many geodetic and surveying/mapping related journals.
