Michael R. Frecks, LS is president and CEO of Terrametrix LLC and has 30 years
of survey experience in the civil site topographic field along with nine years
in the LiDAR industry as both an innovator and as a consultant/advisor for 3D
laser scanning software development. He has extensive data collection
experience and expertise in the transportation and architectural disciplines.
As a professional land surveyor since 1992, Michael’s approach to data documentation
combining GPS, 3D laser scanners and INS, makes his approach more accurate,
safer, faster and cost efficient. His vast knowledge of scanner specifications,
identifying software and hardware capabilities and how they interact with each
other, beta testing of equipment and software, and his demand of high accuracy
standards have advanced the evolution of acquiring as-built data documentation
through 3D laser scanners. Michael writes regularly for
GeoDataPoint. He can be reached at
Face it: sometimes your accuracy just hits the iceberg. We have seen error reports within 0.011 of a foot and we’ve seen them crest near 0.080 of a foot. The key to obtaining LiDAR accuracy is understanding the components.
