Step 4: Once the grid square is located, the next step is to determine the graticule plottingmeasurements. You learned this procedure in Lesson 3 but for a refresher let us go through it again.From the DA Form 1932 (fig 4-12) you determined that the graticule ticks UTM grid value is289983.006 meters east and 4291600.212 meters north. From these coordinates we can determine thatthe graticule tick lies 983.006 meters from grid line 289E, and 600.212 meters north of grid line 4291N(fig 4-14).Figure 4-14. Plotting 983.006 meters/600.212 meters.Step 5: By multiplying these meter measurements by the conversion factor (.002) we can determinethe centimeter plotting measurements.Therefore, the graticule tick 77° 25'W 38° 45' is plotted 1.966 centimeters east of grid line 289E, and1.200 centimeters north of grid line 4291N.79
