SUBCOURSE EDITION - Modern Prepper

4. In the center portion of the form, there are four straight lines with numbers at the end of eachline. These four lines represent the first full grid lines and the numbers represent the value of the gridlines. If you examine figure 1-4, you will see a straight line running in the north-south direction on theleft side of the form. At each end of the line is the number 283. This line and number represent thefirst full (easting) grid line along the west edge. Let us reexamine figure 1-4 and determine the north,south, and east grid lines. The line running in an east-west direction (northing grid line) just above thescale information is labeled 4291. Therefore, the first full grid line along the north has a value of 4291.a. If you look further down the form you will see another line running in the east-westdirection. This line represents the first full northing grid line along the south edge of the grid. Its valueis 4265. Now we have three of the grid lines. The last grid line to be determined is the first full gridline along the east side. On the right side of figure 1-4 is a line running in a north-south direction. Itsvalue is 303. This is the first full easting grid line along the east side of the grid. You have nowdetermined that the first full grid lines are as follows:north edge - 4291south edge - 4265east edge - 303west edge - 283With this information you can now determine the number of grid lines needed for the grid.b. Before you go any further, let us first find out what is meant by "first full grid line."Examine the Leavenworth map sheet provided in the back of this subcourse. If you look in thesouthwest corner of the map you will see the grid line 328000 meters E. Follow the grid line up themap sheet and you will see that it does not go all the way to the top of the map sheet. The next gridline, 329, runs from the south edge to the north edge of the map. This is the first full easting grid linealong the west edge of the Leavenworth map. Examine the 4346 grid line along the south edge of theLeavenworth map. This grid line also does not run across the entire sheet. Therefore, the 4347 gridline is the first full northing grid line for the south edge of the map.8
