Preparing UTM Coordinates on a Base Map forCopying to a Field Map6.1 Position a sheet of paper, the same size as the paper ontowhich the map will be copied, over the area of the base mapwhich is to be copied.6.1.1 When placing the paper, consider that succeedingsteps o

20、f the paper.6.3 Place a piece of removable, nondestructive tape, such aswhite copy or correction tape or transparent tape, on the basemap along the entire left edge of the paper.6.4 Remove the sheet of paper from the base map.6.5 Wherever the tape along the bottom edge of the copyarea crosses a vert

22、s of the corresponding UTM coordi-nates from the left or right side of the map to the tape.6.7 Place the marked area of the map on the copy machine,with the lower left corner of the tape being the referencecorner. Ensure that the information transferred to the tapeappears within the copy area, consi

Reading the UTM Coordinates for Search and RescueOperations7.1 Reading the UTM coordinates using eight digits pro-vides a 10-m (32.8-ft) accuracy. All
24、 numbers are read right,then up. Reading four digits to the right and four digits upprovides the eight digits.7.2 The four digits read to the right and the four digits readup are the ten-thousands, thousands, hundreds, and tens ofmetres.7.3 The ten-thousands and thousands of metres digits areread di
25、rectly from the map and are the digits transferred to thetape in 6.3. The hundreds of metres digit is the first interpola-tion from the grid overlay and the tens of metres is the secondinterpolation.8.

METHOD FOR FINDING THE UTM COORDINATES OF A POINT ON A1:24 000 SCALE USGS TOPOGRAPHIC MAPX1.1 On a 1:24 000 scale USGS topographic map (712min), the UTM values are shown at tick marks along the edgesof the map. At each tick mark there is a three- or four- digitnumber. The first
27、 one or two numbers will be printed smallerthan the third and fourth. One of the numbers along each edgemay have small trailing zeroes and the letter “m” with a larger“E” or “N.” See Fig. X1.1. Position is reported using thesenumbers.X1.2 The intersections of the UTM tick marks form squares1000 m to
28、 a side.X1.3 To find the UTM coordinates of a point, the 1000-msquare containing the point is divided into ten equal parts ineach direction and the position is reported in tenths readingright, then up. Dividing the grid into tenths can be done byestimating or with a transparent overlay. Each UTM gri
29、d for agiven map scale is the same size and is a true square (heightequals width; sides are at right angles), which is why anoverlay can be used.X1.4 As an example of determining UTM coordinates, theposition of “X” in Fig. X1.2 will be found.X1.4.1 First, the “X” is to the right of the large digits
30、“92”(ignore the letters and small numbers). Then, counting to theright, the “X” is between Lines 6 and 7. Since it is closer toLine 6, its position is noted as 926.X1.4.2 Next, find the large digits that the “X” is above or upfrom, in this case, “96.” Then counting up, the “X” is betweenLines 5 and
31、6. Since it is closer to Line 5, its position is notedas 965.F2099 01 (2014)2X1.4.3 The location of the “X” would be reported as“926965.” The coordinates are read right and up.X1.4.4 This set of six numbers locates the position of “X” towithin 100 m.X1.5 To find the position of “X” within 10 m, the
32、100-msquare containing “X” is divided into tenths in a similarfashion.X1.5.1 The center of the “X” is to the right of Line 6 andapproximately one quarter of the way across the 100-m gridtowards Line 7. This coordinate would be 9262 (or 9263depending on how the position is interpolated.)X1.5.2 In the
33、 vertical or up direction, the center of the “X”is three or four tenths of the way up from Line 5. Thiscoordinate would be 9653 (or 9654).X1.5.3 The position of “X” would be reported as 92629653.This locates “X” to within 10 m.X1.6 Always report the right then up coordinates, but do notuse those wor
34、ds in the position report and do not leave a spacebetween the numbers. A pause may be inserted between thetwo sets of digits when reading them aloud.X1.7 There must always be an even number of digits in thelocation coordinates so a leading or trailing zero (0) must beused when necessary.X1.8 The num
35、ber of digits in the right and up coordinatesmust be equal.X1.9 As a second example, the location of “Y” is 920968 towithin 100 m and 92049679 to within 10 m.X1.10 A grid, drawn to 1:24 000 scale is shown in Fig.X1.3. When copied onto transparent material, it can be used asan overlay for determining
