What do hachured
lines show?
What are the rules
concerning hachured lines?
What are the steps to draw a
topographic profile
place a piece of paper between the points
mark where every contour line
touches the edge of the paper
determine the elevation of each mark
place the paper on the graph and mark the
elevation of each contour line
Using the map and chart below,
construct a topographic map profile.
Please match the contour map on the left with the profile on the right.
The elevation of Albany is 282 feet.
The elevation at Binghamton is 1634 feet.
Calculate the gradient to the nearest tenth
of a ft/mi. Show all work.
gradient = change in elevation
distance
= 1634-282
115 miles
= 11.8 ft/mile
= 1352 ft
115 miles
The elevation of Watertown is 99m.
The elevation at Oswego is 144m.
Calculate the gradient to the nearest tenth
of a m/km. Show all work.
gradient = change in elevation
distance
= 144 - 99
= 45 m
75 km
75 km
= 0.6 m/km
If the distance between
the two
circled cities is 425 km,
calculate the temperature
gradient to the nearest
hundredth?
Show all work.
gradient = change in temperature
distance
= 82-48 = 34 = 0.08 °F/km
