PhotoSat has invented a process to produce the most accurate elevation surveys from satellite photos with elevation accuracies better than 20 cm. This engineering quality level of accuracy makes our survey data a viable alternative to LiDAR or ground surveying and is suitable for open pit mining volume change measurements. It is also ideal for seismic planning, access roads, drill pad planning and other civil engineering infrastructure projects. With over 900 surveying projects delivered, our elevation mapping package is available globally. Get safe, easy, accurate and reliable satellite surveys for remote locations, difficult terrain, sparse vegetation or hazardous areas. For more information, click on our website: www.photosat.ca
