MS 217 Dennis Borzakov Class 723 January 15‚ 2013 Problem HOW IS A TOPOGRAPHIC MAP MADE Hypothesis I think that to make a topographic map you have to see the form of the object from up top. To do this you need a satellite image. These images are called aerial photographs. Using elevation calculators and ground measures cartographers then make topographic maps. Materials • Clay model landform • Water tinted with food coloring • Transparency • Clear

BASIC MAP READING Introduction Maps and their substitutes are of particular value to the military establishment. It is frequently necessary to identify ridges‚ valleys routes of movement‚ and other characteristics of a section of terrain that cannot be reconnoiter in advance. Plans for the future operations must be based on knowledge gained in part from maps their substitutes. Therefore‚ as future member of the AFP‚ you must know how to use and read a map. It is mandatory for you to know

LESSON PLAN IN MAP READING I. OBJECTIVES: At the end of the lesson‚ the Cadets and Cadettes are expected 1. To define what is a map. 2. To explain the importance of knowing on how to read the map. 3. To illustrate on how to interpret different symbols and colors on the actual natural and manmade features. 4. To use the map during land navigation. II. SUBJECT MATTER: Map Reading Ref: CAT-1 Cadet/Cadette Manual III. MATERIALS:

Planimetric Map. A planimetric map presents only the horizontal positions for the features represented. It is distinguished from a topographic map by the omission of relief‚ normally represented by contour lines. Sometimes‚ it is called a line map. Topographic Map. A topographic map portrays terrain features in a measurable way‚ as well as the horizontal positions of the features represented. The vertical positions‚ or relief‚ are normally represented by contour lines on military topographic maps. On maps

A topographic map is a map that shows the actual shape of the landscape and the various heights of the landscape. The map allows geographers to see the height and shape of the land by using contour lines. Contour lines are lines that join together all points that have the same height above sea level. The height between contour lines is called the contour interval. The map on the opposite page has various contour lines with an interval of 50 metres. The numbers on the contours show how high the land

[1] In cartography‚ a contour line (often just called a "contour") joins points of equal elevation (height) above a given level‚ such asmean sea level.[2] A contour map is a map illustrated with contour lines‚ for example a topographic map‚ which thus shows valleys and hills‚ and the steepness of slopes.[3] The contour interval of a contour map is the difference in elevation between successive contour lines.[4] More generally‚ a contour line for a function of two variables is a curve connecting points

to read a topographic map. General Purpose: To inform Specific Purpose: As a result of my speech my audience will be able to clearly read and identify parts of a topographic map. Central Idea: To read a topographic map correctly one should follow four important steps: study the title of your map; examine your legend; study the contour lines; and view the map in 3D. Introduction: I. Topographic maps are not just any ordinary map. There are a few rules that a topographic map must obey

classification given by Shape (1938)‚ Hutchison (1968)‚ D.J Varnes (1978) and fundamentally all these classification are based on the factors such as types of material‚ soil moisture‚ climate‚ geomorphic attributes (like Slope forms‚ weathering topographic profile)‚ landslide morphology‚ type of movement‚ triggering mechanism and the speed of the movement. Nepal is a country comprised of 83 precent hills and mountains‚ and steep terrain ‚ fragile geology‚ and seasonal monsoon rainfall contribute
