Figure 5-2. Heading information of DA Form 1959 for station "Adams."b. Control point location (fig 5-3). The location of the control point, in UTM grid coordinatesand geographic values, is located on the three lines below the heading information. The control pointwill be plotted using the UTM grid coordinates, therefore, the geographic coordinates can be ignored.By examining the form, (fig 5-3) we can determine that the UTM grid value for control point "Adams"is 287857.217 meters E, 4278450.145 meters N. From what you have learned in Lesson 3, we candetermine that the control point lies 857.217 meters east of grid line 287 and 450.145 meters north ofgrid line 4278. Since we cannot accurately plot these meter measurements on the grid, we must multiplythe meter ground measurements by the conversion factor of .002 (fig 1-1). Therefore, control point"Adams" is located 1.714 centimeters east of grid line 287 and .900 centimeters north of grid line 4278(fig. 5-4). These centimeter measurements are used to plot the control point which you will learn howto do in Lesson 6.Figure 5-3. UTM Grid values and geographic values (DA Form 1959).99
Figure 5-4. Grid showing location of "Adams."c. Sketch (fig 5-5). A sketch of the control point is located in the lower right corner of DAForm 1959. Although the sketch is not used to plot the control point, it is used by the cartographerduring compilation to locate the point on aerial photography. During the compilation phase, you willneed this sketch to locate the control point on an aerial photograph, so that the compilation base andphotograph can be accurately aligned to each other.3. These are the only parts of DA Form 1959 that a cartographer needs to plot geodetic control.During your next lesson you will learn how to plot the control on a grid and projection.100
