ACCURACY OF THE PHOTOGRAMMETRIC SURVEY

The accuracy obtainable in photogrammetric surveys depends on the scale and type of photography, the instruments used, the skill of the compiler, the density of ground control, the amount of relief, and the nature of the vegetative cover. These factors relate to the data taken from the photographs.

It is axiomatic that "the greater the accuracy, the greater the cost." The scale of the photography for each project, therefore, should be commensurate with the accuracy required.

Accuracy requirements could be custom specified or referred to some of the known
STANDARDS.
