PPT-Reading Contour Maps (Including Topographic Maps):

Visualizing 3D Surfaces Carol J Ormand SERC Carleton College Eric Riggs Texas AampM University Overview What do we mean when we talk about reading contour maps Example the Topographic Map Assessment. and . Compasses. Navigation Tools. Maps. Road maps. GPS (Global positioning system). Altimeter (altitude). Sextant (astronomy) . Watch. Topographic Maps. Compass. Topographic Maps. What's the difference between a topographic map and a regular map?. a ridge. a valley. g. oing uphill. closer . contours. = steeper slope. contours farther apart = shallower slope. Imagine that the red line represents a geologic contact of some sort. Given that it doesn’t parallel contours we know it isn’t horizontal, and given that it doesn’t cut straight across contours we know it isn’t vertical. Can we tell something about its orientation? . in navigation. By Agata Skupień. Travelling salesman problem. The travelling salesman problem (TSP). is an . NP-hard.  problem in combinatorial optimization studied in operations research and theoretical computer science. Given a list of cities and their distances, the task is to find . exit ticket. Topographic Map Exit Ticket. 1) What . is the contour interval of this contour map? . _____________. 2) Estimate the elevation at point C. . _____________. 10 m. 21 m OR 22 m. Topographic Map Exit Ticket. Topography. Shows the three dimensional shape and elevations of an area of land in two dimensions. Topographic Map. Height above sea level. Elevation. Line that connects places on a topographic map that are all at the same elevation (eventually a closed loop). Contour lines never cross or touch!. Topographic notes. Topographic Map-includes contour lines drawn to represent changes in elevation.. Topographic maps take 3 dimensional ups and downs of the terrain and show them on 2 dimensional surface..
