Description :
This paper offers some cautionary advice in the use of aerial photographs and maps to provide morphological information. Current mapping specifications are reviewed and the prospects for improved accuracy in heighting, given new equipment such as cameras equipped with forward motion compensation, are analysed in the light of recent published material. An analysis is presented of the manner in which random errors in photogrammetric observations can be propagated through a block of aerial photographs. A further analysis is made with the addition of a small systematic error of a type and magnitude occasionally encountered in practice.
