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. Using Visual Patterns to Facilitate Learning. Eight Different Maps. What are Thinking Maps?. Developed in 1988 by Dr. David . Hyerle. . . A common . visual language for learning. . They . have a consistent . Introduction to . Maps. What . is. a map?. A generalized view of an area, usually some portion of Earth’s surface, as seen from above at a greatly reduced size. Any geographical image of the environment. Topographic Maps. Contouring. Topographic contours indicating surface relief. Image taken from US Army training manual.. Solid yellow lines represent surface isobars, line of equal air pressure. Green dashed lines are geopotential heights, the altitude at which 500 millibars of air pressure are attained. These types of contour maps are used by meteorologists. The weather system shown is the Storm of the Century, a powerful winter storm called a nor’easter.. 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!. Mapping Mechanics: . 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. Maps. Topographic Map. :. A . contour map. -. Complicated Topographic Map. Simple Topographic Map. I am standing where the land meets the water, what is this called?. *All elevations are relative to sea level. 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.. interpret topographic maps and satellite views to identify land and erosional features and predict how these features may be reshaped by weathering.
