The use of altimeters in conjunction with aerial photographs offers board possibilities in the mapping of large tracts of land by small parties at a minimum of cost. Since relatively little work has been done on this topic, our party accepted for its thesis subject a two-fold plan intended to test the suitability of this method of elevation determination both under laboratory and under field conditions.
