PhotoSat surveys take mining projects from the Preliminary Economic Evaluation (PEA), through feasibility, and on to mine construction planning. Most of the world’s major mining engineering companies have successfully used PhotoSat surveys for all phases of mine development. PhotoSat has completed over 1200 surveys of mine sites and tailings storage facilities worldwide, providing the world’s most accurate satellite survey data.
Mine site planning and construction requires engineering quality topographic surveying. PhotoSat’s geophysicists apply signal enhancement, noise attenuation, and image matching from seismic data processing to systematically produce elevation grids from stereo satellite photos that are accurate to better than 15 cm in elevation.
The accuracy of PhotoSat’s surveys increases with the availability of ground control survey points. However, PhotoSat can conduct surveying using an initial process and reference system that does not rely on ground control points. This process is unique among mining project survey methods and enables us to detect errors in the ground survey data that may be undetected by other survey methods.
We regularly publish case studies and reports that share the real-world application of our satellite surveying. Read more for proven success stories, accuracy reports, and best practices that demonstrate the effectiveness of our satellite surveying packages.
Satellite surveying enables design engineering teams and Engineers of Record to independently confirm that earthworks constructions are consistent with designs. Mine operations engineers get regular snapshots of all aspects of the mine site including accurate volume measurements of all visible mine elements. PhotoSat’s high accuracy elevation data is used for mine feasibility studies, construction cut and fill volume calculations, reserve and resource estimates, drill hole planning, and project base mapping.
