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.
