Answer:
BAHASA INDONESIA= jika dua garis kontur
berurutan berjarak 75 kaki, berapa interval
kontur untuk peta khusus ini
BAHASA INGGRIS= if two successive
contour lines are 75 feet apart, what's the
contour interval for this particular map.
Divide the difference in elevation between
the index lines by the number of contour
lines from one index line to the next. In the
example above, the distance 200 is divided
by the number of lines, 5. The contour
interval is equal to 200 / 5 = 40, or 40-unit
contour intervals.
Individual contour lines on a topographical
nap are a fixed interval of elevation apart
known as a contour interval. Common
contour intervals are 5, 10, 20, 40, 80, or
100 feet. The actual contour interval of a
map depends upon the topography being
represented as well as the scale of the map
Contour line, a line on a map representing
an imaginary line on the land surface, all
points of which are at the same elevation
above a datum plane, usually mean ses
|evel. The diagram illustrates how contour
lines show relief by joining points of equal
elevation.
