Surveying & Mapping

GPI has emerged as one of the most innovative and progressive firms in quality survey and mapping solutions. We offer traditional survey techniques as well as 3D laser scanning or terrestrial LiDAR for projects ranging from site designs to indoor fit-up plans. In 2014, we purchased our first mobile LiDAR sensor, which is capable of collecting 1.2 million points per second while traveling at highway speeds. This innovative solution has since grown into our ability to capture aerial data utilizing UAVs, as one of the first engineering firms permitted by FAA to offer survey and mapping from a drone platform.
