Excerpt from Topographic Maps and Sketch Mapping
A map is a conventional picture of a portion of the earth's surface as seen from directly above, showing more or less completely the various features of the country represented. Thus a land map may show only the boundaries of a certain piece of property and would consist simply of a series of lines forming a closed figure with the lengths and directions deter mined by the surveyor - in short a conventional outline of the property in question. On the other hand, a complete topographic map, such as would be used in planning a landscape design for a park or estate, for example, would show every detail of the property - houses, roads, streams, and even, in some cases, individual trees as well as the relief, or ups and downs of the land Surface which form its hills and valleys. Between these two extremes are all sorts and kinds of maps used for various purposes.

Excerpt from Topographic Maps and Sketch Mapping
The demand for instruction in map reading and sketch mapping, brought about by the Great War, has led to the development of a course on this subject in many of our colleges and technical schools which have assisted in preparing men for the various officers' training camps. Outside of the purely military field our universities have in the past found it necessary to develop a course of this character for students in Geology and Physiography who are required to make extensive use of topographic maps. In recent years the development of the automobile and the camping habit has led to a more extensive use of maps by the general public, and a large number of people have "discovered" our own United States Geological Survey Maps, but are still unable to understand them completely and to make the fullest possible use of them.
It will doubtless be necessary in the future for many educational institutions to continue instruction in this subject for students taking reserve officers and other military training courses in connection with their regular college work. Furthermore it seems probable that in many of our institutions the demand and necessity for such a course will lead to its inclusion as a regular academic study, given perhaps as a part of the instruction in Geology or Geography, or as a separate course under Civil Engineering. It is with this idea in view that this volume has been prepared.
A large number of educated people have never learned to use topographic maps because it has been the general opinion that considerable mathematical knowledge was necessary. This is far from true.
