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.
Often times in our technology, keeping the advantage results in a closed system of information. That can be detrimental to your clients’ understanding of the process and, often, the request for deliverables. Learning how to manage project owner expectations is crucial to building a mutually beneficial venture. In order to address owner expectations, it is important to first understand how expectations are defined.
Mother Nature really pulled a joke on us this year. Up to 7 feet of snow blanketed parts of western New York, then flooding; Detroit already has seen its seasonal snowfall; Buffalo 8 feet of snow in one day; 80 percent of California is in either extreme or exceptional drought; lava flowing like molasses in Hawaii and in the Midwest where the temperature can swing in extremes of 100 degrees we do not welcome the frigid temperatures we have seen before Thanksgiving.
As a land surveyor in the Midwest we learn to acclimate to extreme weather, however according to Survival Magazine it is easier to acclimate to heat than it is to cold. Query any job description for a land surveyor and they all state “must be able to work in extreme weather conditions.”
Fall is one of my favorite times of the year. The kids go back to school and the bounty of foods from our nation's farms come in from the fields. It also means report card performance and attention to freshness. When it comes to mining data of a dynamic world what is the shelf life?
Nothing relaxes me more than kicking back after work watching sports competition. So the 17 days of the XXII Olympic Winter Games was almost as good as a vacation. Now that the flame has been extinguished in Sochi I wonder what subliminal message about my business of 3D data documentation these 88 nations and 2,871 athletes provided me.
