Topographic Mapping Notes
What is Topography?
Mapping Elevation/ Features such as mountains or rivers
What does a topographic map tell you, that other maps can't?
Topographic maps could tell elevations while other maps can't.
Who might use a topographic map and why?
Airlines could use topographic maps to see if they are about to hit a mountain. Scientists use topographic maps to check the geography and the structure that mountains are built with.
Define the following:
Elevation: Height of a place relative to a reference height.
Contour lines: A line connecting points that have the same elevations.
Contour Interval: The difference between two adjacent contour lines.
Depression Contour: Contour lines indicating
Bathymetry: Topography in the ocean- They use sonars to map the ocean.
