Alaska Spatial Referance Page

Alaska doesn't (yet) have a formal Spatial Reference Center, but I will put some info of use to Land Surveyors and others using spatial reference data on this page. At the moment it just has some presentations.

PDF files of presentations given at UAF Distance Education center on March 12, 2009:
Basics of GPS -- how it works (2.6MB)
Summary of GPS applications (17MB)

Right now I am working on an update to the HTDP (Horizontal Time-Dependent Positioning) model for the NGS. This model is used by surveyors to correct survey positions for crustal motion.
