    NOTE: THIS IS NOT A COMPLETE


    GUIDE. You should already be
    familiar with the topics within this
    presentation, and should seek
    additional information for
    definitions and terminology.

    Basic Map Skills

    Identify Grid
    Identify Elevation
    Grid vs. Magnetic Azimuth
    Determine Azimuth
    Back Azimuth
    Determine Distance

    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, non-surveyed
    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

    Identify Map Symbols


    Refer to Map Legend

    Marginal Information
    Geographic area and scale - top left
    Name of map sheet - top center
    Map edition, map series, and map sheet
    number - top right
    Legend - bottom left
    Bar scale, contour interval, grid
    reference box, and declination diagram
    - bottom center
    Elevation guide, adjoining map sheet
    diagram, and boundaries box - bottom
    right

    Terrain Features - Major

    Hill
    Ridge
    Valley
    Saddle
    Depression

    Terrain Features - Minor


    Draw
    Spur

    Terrain Features Supplementary


    Clif
    Cut
    Fill

    Identify a Grid

    Identifying a Grid
    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

    THREE NORTH'S
    N

    TRUE NORTH

    MAGNETIC NORTH

    GN

    GRID NORTH

    Determine Azimuth

    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

    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
    Intersection
    Single Point, 2-Point, etc

    Resection
    Single Point, Dual Point, etc
