Description
Control points are captured by land surveyors to create control for orthophotography. These points are captured with survey-grade equipment ensuring the highest accuracy in their location.
Horizontal Control Point: Surveyed horizontal geodetic control points that are used in the development of an analytical aerotriangulation solution.
Vertical Control Point: Surveyed vertical geodetic control points that are used in the development of an analytical aerotriangulation solution.
