Railroads

GPI utilizes the most advanced airborne and terrestrial Class 3 LiDAR sensors mounted on a high rail vehicle and on a helicopter platform capable of generating +/-0.05’ accuracy and collecting data points on the top of the rail itself for a highly accurate rail centerline. We produce an extremely dense point cloud capable of right-of-way feature extraction and highly detailed Digital Terrain Models (DTM) for rail design. Our experience also encompasses “green field” mapping for initial project planning utilizing our fixed-wing, rotary, and UAS aircraft; coupled with our digital sensors to create an ortho-rectified mosaic image of the entire proposed project and and also perform planimetric feature extraction of all structures in the potential ROW. All of GPI’s precision mapping products incorporate traditional ground survey, 3D modeling, digital imagery, static, mobile, and aerial LiDAR. All mapping products are signed and sealed by a professional surveyor.

GPI is the trusted company to integrate aerial imagery, LiDAR data, ground control survey and bridge/tunnel laser scanning data into accurate 3D Digital Terrain Model for Railroad projects of all types including intermodal connections anywhere in the United States.
