This paper discusses two new algorithms for obtaining the height of an arbitrary point onthe ground directly through photographs. They Can be efficiently used to compute the terraincorrection of gravity and operate an orthophoto with contours. The programming for the newprocedures is much simpler and clearer than the algorithms available. The memory spacerequired has been reduced to the minimum, and the amount of operations is more economical,especially in the case of terrain correction of gravity. This paper gives also some numerical examples for two mathematical models of terrainby means of fabricating photographs.
