Topographic maps are used to
display a geographic graticule and a coordinate grid. The term topography means
an arrangement of the natural and artificial physical elements of a geographic
area. Therefore, a multidimensional geographical representation of a region is
called a topographic map. The cultural imaging encapsulates the three
dimensional images of roads, buildings, railways, airports, new names of places,
urban development, geographic features, national and international borders and
several reserves.
Reading Garmin Topographic Maps
Garmin Topo Maps makes use of
color lines, which are helpful in indicating elevation variation in the
surface. To identify
a contour line representation, on must have strong visualization skills. In
fact, map, symbols are used on a Garmin
Topographic map to indicate elevated or non-elevated regions and
objects. Contour lines are representative of elevation. These lines are
generally in brown color. Some are regular thin brown lines, while others are
relatively thicker. Numbers written in brown alongside contour lines indicate
elevation.
Green colored areas on the map
signify forest capped areas. Roads and trails or other human-made features on
the map are shown in red or black. Roads are indicated with a double line or
thick red lines. A range of codes is used to indicate road quality. The natural
color blue is used to indicate water bodies, streams, rivers, and lakes. Occupied
buildings are shown in black in shape of solid squares, whereas, a hollow
square with a black outlined usually indicates that the building is inhabited.
