Topography Maps A map provides a representation of natural and artificial features. Shows you the ups and downs

Who cares??

Does this paint a 3-D picture?

Lines Elevation If you walk along a slope without going up or down you will be following a line on the same elevation or topographic line

Low water level The line is long and follows the outline of the island

Medium water level The line around the island is shorter

High water level The line is very short with only the very top showing.

All lines of elevation shown Is is your map

Note the cross section Look at the steep slope on the right side

How high is the peak at D & C? You must ask “what is the contour interval?” or space between contours 10 meter, 100 feet? This map shows 10 meters. The peak height is 30m plus. What if the interval is 200 meters.

If doesn’t matter what the interval is, closer is steeper, wider is flatter. How steep will be depend on the contour interval

What terrain is between A & C? Flat > increasing slope > steeper > peak > shallower down slope > getting steeper as the drainage is crossed

Look at what you know, road- shoreline-penisula building-river- drainages- steep slope- peak height

Peak or hole?

Peaks on the left and depressions on the right
