ROCK Ultra — Seamless Precision in Urban Complexity

Experience the ROCK Ultra with GPI, where Senior Survey Technician Chris Stein put the system to the test at Tuscan Village—a large-scale urban redevelopment in Salem, New Hampshire. Once a retired dog track, the site is transforming into a modern, walkable mixed-use community featuring residential, retail, and commercial spaces.

Flying at 380 ft AGL (≈115 m) and 10 m/s, the ROCK Ultra captured intricate curb lines, dense brake line geometry, and structural details across the site—all in a single 45-minute flight. The result: a dense, survey-grade point cloud that set a new benchmark for urban LiDAR mapping precision, efficiency, and data quality—completing what would have taken months with traditional methods in under an hour.
