PPT-Topographic Map Skills

Topographic notes Topographic Mapincludes 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. 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? .

McKnight’s Physical Geography. YM . Wang, . S. . Holmes, J Saleh, XP Li . and D . Roman, . National Geodetic Survey. June 22 -25 WPGM 2010 Taipei, Taiwan. Abstract. The spherical harmonic expansion of the topographic gravitational potential has two major advantages over Newtonian integrals: it offers computational efficiency and facilitates spectral analysis of the Earth’s gravity field. The high degree harmonic expansion of the topography helps also in geoid computations.. Techniques in Active Tectonic Study. Juni 20-Juli 2, 2013. Instruktur: Prof. J Ramon Arrowsmith (JRA).

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. Aim: To be able to interpret a topographic Map.. What is a Topographic Map?. A topographic map. shows surface features,. or topography, of the . Earth. . Topography can be natural or human-made. interpret topographic maps and satellite views to identify land and erosional features and predict how these features may be reshaped by weathering. A 2D view of a 3D surface. How. do topographic maps give you a picture of what the landscape looks like?. TOPIC-MAPS. GEOGRAPHY. CLASS-VI. WHAT ARE MAPS?. A map can be defined as a two dimensional representation of the whole or part of the earth drawn to scale on a flat surface.. A collection of maps is called an atlas. Yonathan Admassu, PhD.
