| Summary: | absolute accuracy of 0.3 meter between projects, countries addressed. Of special interest are the short project times and continents. The problem of overlaying data has been and resulting cost savings over conventional methods. as registration points, are able to produce data with an can be included in data sets that cover entire countries. capture. Data collected using one set of control points may comprehensive, from setting initial control points to cover very large areas. Data obtained from the International datum and projections, and the use of existing data sets are details a procedure for setting base control points that distances has highlighted an existing problem with data establish control points anywhere in the world. Researchers gather spatial data on a scale that was, until recently, cost GPS Service for Geodynamics (IGS) is used in conjunction with or may not overlay data collected using another. This thesis presented. The project in Texas is the same size as the prohibitive. Projects that cover an area of a few hectares project in Azerbaijan, but on different continents. The project in Mali is much larger and has been the most reduced to the point that it is insignificant. Issues of Specific projects in Texas, Azerbaijan, and Mali are The ease at which point locations can be measured over large The Global Positioning System has enabled researchers to the International Terrestrial Reference Frame (ITRF) to training local researchers in data collection. utilizing these control points for base station locations or |
