PROPOSED MANUAL ON SELECTION OF MAP USES, SCALES, AND ACCURACIES FOR ENGINEERING AND ASSOCIATED PURPOSES: MAP AVAILABILITY -- CHAPTER VI

During the planning and design of engineering works, various uses of maps are required due to the varied levels of required information. Various agencies of the U. S. Government produce a multitude of maps, each with a specific usage intended. Lesser known, are some of the map products produced by agencies of state governments, i.e., general highway maps, geologic mapping, etc. Also available to the map user are the by-products of mapping such as aerial photography, diapositives, copy negatives, feature (and color) separates, and digital information. Hydrographic surveys are the basis of nautical chart information and copies of these surveys may be obtained on request. Highway plan sheets and railroad valuation maps provide valuable data regarding these modes of transportation. Maps useful to the petroleum industry include structure maps, base maps, and lease maps.
