Investigating the Decodability of Small Topographic Objects in Large-Scale Aerial Photography,
Abstract
Studies of the recognizability of small topographic objects in various types of large-scale aerial photographs were conducted for the purpose of establishing to what extent the application of each of their types increases the possibility of an office and field type decoding and permits a reduction in the ground-based pre-surveying of the objects not reflected during the aerial photographing in the scales governed by the instructions. Experimental studies were conducted in a wooded region where the recognizability of the small topographic objects is minimal, and in an open populated region where the concentration of such objects is fairly high.
