We will coordinate ground control targeting or premarking as required for mapping. Prior to the image acquisition, selected locations will be identified with targets, which will be visible in the aerial photography. Horizontal coordinate, and elevation data, for the targeted points is acquired by qualified surveyors. This data is then used in the aerotriangulation process.  Even with our sophisticated airborne GPS and IMU systems, the requirements for good control cannot be overlooked.
