Our Company Profile

Born of distinguished corporate parents, GEOspatial Professional Solutions Inc. (GPSi) traces its roots back to the 1970s. Pedigreed by a lineage of photogrammetric expertise, GPSi features the next generation of geospatial solutions that encompass photogrammetry, remote sensing and geographic information systems.

GPSi is a one-stop resource that offers the best of both worlds: a 30-year legacy of high quality service and robust client base coupled with a certified small woman-owned minority (WMBE) business. In essence, GPSi is an enterprise with the reach and staying power of a larger company but with the compulsion to innovate, hi-tech prowess and entrepreneurial vigor of a smaller company.

GPSi is proud to be the first mapping company in North America to offer the UltraCam Falcon prime (PDF specs), the digital aerial mapping camera tailored for high accuracy, design grade engineering mapping. With features like 196 megapixel image format, a 1:2.2 pan sharpen ratio that collects PAN, RGB and NIR in parallel, and forward motion compensation by TDI, this camera delivers the same technical capabilities of larger models. The ability to deliver true-color and color-infrared (CIR) image quality with unmatched radiometric range, makes it ideal for our smaller large-scale and photogrammetric projects, high-resolution orthophoto production, precision photogrammetry, corridor mapping, and Lidar integration.

We are also the first company on the West Coast to own RIEGL®'s LMS-Q780 (PDF data sheet) aerial Lidar sensor. With the exciting purchase of this full waveform airborne laser scanner, GPSi now offers full Lidar services including data aquisition, post-processing, filtering, and classification.
