Introduction
Currently researching the coordinate systems of the world to publish in my monthly column for PE&RS. Also, I continue research on the geodesy of subsidence in Louisiana through GPS Continuously Opererating Reference Stations (LSU has 200+ sites expanding throughout the U.S. Coast of the Gulf of Mexico) as well as Relative and Absolute Gravity observations. From time-to-time I provide research and Expert Witness testimony on Forensic Photogrammetry to Civil and Criminal Court proceedings.

The territory of Greece and of Bulgaria bordering on the north, as well as in present-day Northern Macedonia, which was annexed to Serbia only two years before WW1, was not systematically mapped on a large scale before the war. For this reaso...
The territory of Greece and of Bulgaria bordering on the north, as well as in present-day Northern Macedonia, which was annexed to Serbia only two years before WW1, was not systematically mapped on a large scale before the war. For this reason, the Allies had to devise their own system for mapping the position of the front: this was the Macedonian...
The existing coordinate system for the entire country of Ecuador is the Provisional South American Datum of 1956 (PSAD56) which originated in La Canoa, Venezuela. This coordinate system is considered one of the major datums of the world and is generally associated with the countries of South America that comprise the Andes Mountain Range. The syste...

In this study, the terrestrial and marine gravity data sets undergo refinement and validation for the sake of precise geoid determination in Louisiana. The erroneous gravity data represent the main source of errors that can easily propagate into the geoid if not refined and eliminated. The purpose of this study is to ensure the integrity of the rel...
