J. Anthony Cavell PLS, CFedS

Tony Cavell’s first field of interest was Physics, and he worked in Dr. William Hamilton’s gravitational wave lab at Louisiana State University.  Mr. Cavell then went to work for Murray Hawkins at the LSU Petroleum Engineering Department, which is now named in Mr. Hawkins’ honor.

Mr. Cavell left LSU to work in construction in the New Orleans area.  While in construction he became familiar with the tools of surveying, which led him to seek a professional surveyor license.  Mr. Cavell’s surveying career started with boundary work and engineering studies.  He then joined John E. Chance and Associates, surveying offshore in the early days of using satellites for surveying.

Mr. Cavell brought that experience to NEI, which he joined as vice president. At NEI, working through the US Dept. of Transportation, he went to the Kingdom of Saudi Arabia to train their surveyors on GPS.  Mr. Cavell became the CEO of NEI after the death of its president, Charlie Poché.

He left NEI to pursue consulting.  While with ESP Associates, Mr. Cavell did the quality assurance surveys for the Louisiana LiDAR project Watershed VI Joint venture with the Federal Emergency Management Agency (FEMA).  He also began consulting for attorneys as an expert witness.

Dr. Roy Dokka was starting a new Center for GeoInformatics (C4G) to study plate tectonics and subsidence in Louisiana, and Mr. Cavell recommended a network of GPS receivers for Dr. Dokka’s work.  Mr. Cavell became associate director of C4G, and together Dr. Dokka and Mr. Cavell built the GULFnet network of continually-operating reference stations (CORS) that today number over 100 across the state of Louisiana and along the Gulf of Mexico.  Mr. Cavell left the center but was asked to return after Dr. Dokka’s death.

Throughout his surveying experience, he has been active in professional organizations, serving as president of Louisiana Society of Professional Surveyors (LSPS) and more recently as president of the National Society of Professional Surveyors (NSPS).
