Map Colors Black - Indicates cultural (man-made)

features such as buildings and roads, surveyed spot elevations, and all labels Red-Brown - Combined to identify cultural features, all relief features, nonsurveyed spot elevations, and elevation, such as contour lines on red-light readable maps

Map Colors

Blue - Identifies hydrography or water features such as lakes, swamps, rivers, and drainage Green - Identifies vegetation with military

significance, such as woods, orchards, and vineyards Brown - Identifies all relief features and elevation, such as contours on older edition maps, and cultivated land on redlight readable maps

Map Colors Red - Classifies cultural features,

such as populated areas, main roads, and boundaries, on older maps Other - Occasionally other colors may be used to show special information. These are indicated in the marginal information as a rule

Read Right then Up Bottom left corner identifies first

two digits I.e. 12__56__ Use coordinate scale to identify last two digits I.e. __34__78 Add proper grid zone designator to front I.e. AB ________

Identify Elevation Elevation

Locate point on the map Determine contour interval of map Locate index contour line nearest point Count number of contour lines up or down that must be crossed to get to point Points at top of hill add half the contour

interval Points at bottom of depression subtract half the contour interval Grid vs. Magnetic Azimuth

Determine Azimuth VGT 55 Determine Azimuth

Plot location of two points

Use straight edge to draw line between both points (line must be long enough to cross scale on protractor) Use protractor to determine azimuth

VGT 46 VGT 59 Determine Back Azimuth

Back Azimuth

Back Azimuth - azimuth taken from a distant point toward your location Used in Resection Numbers less than 180 - add 180 Numbers greater than 180 - subtract

180 Determine Distance Determine Distance

Straight Line

Use edge of paper and mark distance between points Line paper up next to scale to determine distance

Road Distance Break curve into series of straight lines and measure from curve to curve

Line paper up next to scale to determine distance Advanced Skills
