Dr. Larry B. Conyers is an Assistant Professor of Anthropology at the University of Denver. He received his Ph.D. at the University of Colorado in 1995. Dr. Conyers is actively involved in archaeological ground-penetrating radar projects throughout the world and is the foremost archaeological GPR practitioner in the United States. He has worked in Central and South America, Asia, Europe, Hawaii, and many areas in the continental United States. Much of his work is sponsored by the National Center for Preservation Technology and Training (NCPTT) which is also NADAG's sponsor.

GPR_Process is a program that produces amplitude slice-maps of GPR data. This program was written with archaeologists in mind. It is a Windows-based program created by Martha West that overlays a more sophisticated C++ program originally written by Jeff Lucius of the U.S. Geological Survey in Denver. This program was produced with support from the NCPTT and can be downloaded free of charge.
