​

Answer 1

Answer:

Interpreting the colored lines, areas, and other symbols is the fi rst

step in using topographic maps. Features are shown as points, lines,

or areas, depending on their size and extent. For example, individual

houses may be shown as small black squares. For larger buildings,

the actual shapes are mapped. In densely built-up areas, most individual buildings are omitted and an area tint is shown. On some

maps, post offi ces, churches, city halls, and other landmark buildings

are shown within the tinted area.

The fi rst features usually noticed on a topographic map are the

area features, such as vegetation (green), water (blue), and densely

built-up areas (gray or red).

Many features are shown by lines that may be straight, curved,

solid, dashed, dotted, or in any combination. The colors of the lines

usually indicate similar classes of information: topographic contours

(brown); lakes, streams, irrigation ditches, and other hydrographic

features (blue); land grids and important roads (red); and other roads

and trails, railroads, boundaries, and other cultural features (black).

At one time, purple was used as a revision color to show all feature

changes. Currently, purple is not used in our revision program, but

purple features are still present on many existing maps.
