See the tables below for image size, recommended maximum speeds at various altitudes, and optical parameters of your SlantRange system.
Image overlap (along-track) is a function of the data collection rate of the sensor, the size of the image on the ground at the given flight altitude, and the flight speed of the aircraft. The sensor is collecting images approximately once per second, so the distance the aircraft travels in one second should not exceed 80% of the image’s along-track dimension.
Many flight planning software packages will automatically space your flight legs when given the parameters of the imaging system and the required sidelap.
