High-resolution topographic methods
Characteristics of very high resolution optical satellites for topographic mapping
... As mentioned above, the flexible optical satellites can take stereo pairs within the same orbit having just approximately 1 minute difference in time. These stereo pairs are optimal for the generation of digital ...
