Welcome to the Home of LSU C4G
LSU’s College of Engineering created the Center for GeoInformatics (C4G) to build new research and services in Geodesy and GeoInformatics.
LSU Center for GeoInformatics(C4G) in partnership with the Space & Earth Geodetic Analysis Laboratory (SEGAL) at the Universidade de Beira Interior (UBI) and Instituto Dom Luis (IDL), Portugal will provides a framework for advancing geodetic analysis and modeling. Combining the skills and experiences from these of capable and motivated partners will lead to new opportunities that were previously inaccessible.
The partners will collaboratively pursue research and support for the precise point positioning of GPS/GNSS data, gravimetric geoid modeling, and the application of emerging geo-informatics technologies and services. C4G and SEGAL will develop new tools for analyzing Global Navigation and Satellite Systems (GNSS) data. Long term collaboration will also advance the development of a new gravimetric geoid model for Louisiana.
“Subsidence is a leading cause, if not the principal driver of wetlands losses in Louisiana,” - C4G researcher Joshua Kent.
Louisiana’s coastal wetlands are lost at nearly one football field every hour.” - U.S. Geological Survey
“Gravimetric surveys conducted by the C4G will ultimately allow us to re-connect with the geoid to calculate better elevations" and “knowing how high we are above sea level.” - C4G geodesist Cliff Mugnier.
“We have applied our in-house developed software in the computation of regional and national geoid projects in North Mozambique, Madeira and more recently in Bhutan.” - Machiel Bos, SEGAL researcher
“This collaboration is a unique opportunity to partner with a very enthusiastic team that combines pure and applied research in several areas of geosciences with enormous societal implications,” - Rui Fernandes, of SEGAL.
“I anticipate significant innovation from our relationship.” - George Z. Voyiadjis, Boyd Professor and Director of C4G

The NGS presentation on Friday March 15, 2013, pointed out that GEOID12a produces 95% confidence at ± 4 to 8 cm in Louisiana. The NGS conclusion states that the problem is too large for NGS to handle alone and we all need to work together to get better height results. They also recommend partnering with locals to leverage existing resources and that a plan needed to be created to move forward with improving heights.
The presentation was given by NGS geodesists / scientists, Michael Dennis and Dan Roman.
Big picture ideas to consider from the presentation
Recently, NOAA’s National Geodetic Survey released updated orthometric heights for Southern Louisiana relative to the September 2010 GNSS Height Modernization project. These heights represent the most up to date heights available for the region. On March 15, 2013, NGS hosted a free, on-line webinar to present the results of this project.
