The distinctive character istic of a topographic map is that the shape of the Earths surface is shown by contour lines ontours are imag inary lines that join points of equal elevation on the surface of the land above or below a reference surface suc 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? . Lidar-Derived DEMs. Stereo DTM. (Topographic Surface). R. eference image of the traditional stereo-compiled DTM. Built from Masspoints and Breaklines . Much coarser resolution than lidar. Demonstrates the familiar and usually expected character of a topographic DEM. Match your cards.. Take notes in your science notebook.. Label your map.. Map Notes. topography. The study….

An introduction to topography . by the use of contour lines . Upon completion of this lesson, students will be able to:. define topography. define the USGS and different techniques used to study topography. distort a certain property. .. Definition: The representation of the globe on a two dimensional flat map.. All maps have four features that can be distorted that include: Shape, Size (area), distance, and direction. The reason for this being that there is no perfect way to represent a 3-D object on a 2-D plane. Each different type of map sacrifices one or more of these properties to make a flat map. .
