» An independent study compared WorldView‐3 stereo imagery to a highly accurate LiDAR grid to show the vertical accuracy of the WorldView‐3‐derived elevations as better than 15 cm RMSE.
» With global coverage, the satellite industry can now provide LiDAR‐quality elevation models at a scale and speed that is unmatched by other elevation processing technologies
DigitalGlobe’s 30 cm Imagery also delivers industry‐leading accuracy
