PPT-Topographic Mapping

Goals Define and describe topographic maps Define and describe an elevation profile Use a topographic map to create an elevation profile Describe how NASA probes create topographic maps that are used to create elevation profiles. 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 Life Science. Jong Youl Choi. School of Informatics and Computing. Pervasive Technology Institute. Indiana University. (. jychoi@cs.indiana.edu. ).

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.. exit ticket.

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.. 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?. 2 Introduction The National Flood Insurance Program (NFIP) was established to provide flood insurance as an alternative to disaster assistance in exchange for communities adopting and enforcing floo 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. James Madison . University. Who are?. Geotechnical Engineers. Designing earth structures consistent with data. Direct projects.
