Abstract: Generalized techniques are developed whose use can simplify the solution of problems relating to contour maps. One of these techniques makes use of the topological properties of contour maps. The topology is represented by a graphical structure in which adjacent contour lines appear as connected nodes. Another generalized technique consists of utilizing geometrical properties to determine the characteristics of straight lines drawn on the contour map. Both of these techniques hove been applied to the problem of locating the ground track of an aircraft from elevation readings obtained during a flight. [ABSTRACT FROM AUTHOR]

Abstract: The seas have been a means of vessel traffic for centuries. Already in the Antique and in The Middle Ages long voyages were made in the oceans with the smallest vessels. But even Columbus had still to fight against the greatest difficulties during his crossing of the Atlantic on his dangerously small ships. Today, the traffic and the crossing of the oceans has become a matter of course. The ocean, having divided lands, countries and continents, has become an element which makes the separation of space almost inefficient. In periods of low civilization the oceans divided the nations; in a period of advanced and higher civilization it prepares an interchange of goods and thoughts and becomes by degrees the greatest necessity for the countries, because a most comfortable, most important and almost unrestricted traffic with every part of the earth is possible on the Seas.
