16、streams, vegetation, landmark buildings, etc., which constitute the outstanding characteristics of an area. Problems are encountered in the selection of features of secondary importance. selection should be important from a military standpoint. Where choice lies among several secondary features, the
17、 most prominent landmark features are preferable. In areas of moderate or dense culture, a particular feature could be unimportant and its omission would not necessarily detract from the use of the map. On the other hand, a similar feature in an area of sparse culture would be important as an aid in

A map projection is a system of lines drawn on a plane surface to represent parallels of latitude and meridians of long

All DMA maps show the graticule in conventional sexagesimal units (degrees, mii-Jtes, and seconds of arc) with Greenwich as the meridian of reference. Different projections have unique characteristics and serve differing purposes. represented on the

The sheet line of standard 1:100,000 scale maps show the meridians (lines of longitude) as straight lines, and parallels (lines of latitu

Any requirement for any projection other than those mentioned in 3.9 wili be specified in supplementary instructions provided as part of the project assignment. The p

Sheet lines are designed to provide map coverage of an area with the minimum number of sheets without unduly impairing the continuity of adjoining sh
