  4. 4. What is a Map? A map is a graphic representation of a portion of the earth's surface drawn to scale, as seen from above. It uses colors, symbols, scales and labels to represent features found on the ground.
  5. 5. a. Black. Indicates cultural (man-made) features such as buildings and roads, surveyed spot elevations, and all labels. b. Red-Brown . The colors red and brown are combined to identify cultural features, all relief features, non-surveyed spot elevations, and elevation, such as contour lines on red-light readable maps. c. Blue. Identifies hydrography or water features such as lakes, swamps, rivers, and drainage. d. Green . Identifies vegetation with military significance, such as woods, orchards, and vineyards. e. Brown . Identifies all relief features and elevation, such as contours on older edition maps, and cultivated land on red-light readable maps. f. Red . Classifies cultural features, such as populated areas, main roads, and boundaries, on older maps. g. Other . Occasionally other colors may be used to show special information. These are indicated in the marginal information as a rule. Colors used in Map
  6. 6. Symbols used in Map
  7. 7. Scales used in Maps
  8. 8. A map is a scaled graphic representation of a portion of the earth's surface. The scale of the map permits the user to convert distance on the map to distance on the ground or vice versa. The ability to determine distance on a map, as well as on the earth's surface, is an important factor in planning and executing military missions. Scales used in Maps
  9. 9. Scale is reported as a representative fraction with the map distance as the numerator and the ground distance as the denominator. Representative fraction (scale)= map distance / ground distance Scales used in Maps
  10. 10. <ul><li>Distances Shown on the map are proportional to the actual distance on the ground. </li></ul><ul><li>While drawing a map, we should take care about: </li></ul><ul><li>How much of actual distance is denoted by 1mm or 1cm in the map </li></ul><ul><li>- It can be : 1cm = 1 Kilometers or 10 Km or 100Km etc. </li></ul><ul><li>- This scale can vary from map to map but not with in the map. </li></ul>Scales used in Maps
  11. 11. Map Scale Classifications Large 1:75,000 and larger Medium 1:1,000,000 but smaller than 1:75,000 Small Maps 1:1,000,000 and smaller
  12. 12. Understanding Scale used in Maps On a 1:250,000 scale map, the prescribed symbol for a building covers an area about 500 feet square on the ground; - a road symbol is equivalent to a road about 520 feet wide on the ground; - the symbol for a single-track railroad (the length of a cross-tie) is equivalent to a railroad cross-tie about 1,000 feet on the ground.

  26. 26. Points to remember <ul><li>A map depicts the location of a particular object/place in relation to other objects/places. </li></ul><ul><li>Symbols and colors are used to depict the different objects/places. </li></ul><ul><li>There is no reference or perspective in map, i.e., objects that are closer to the observer are shown to be of the same size as those that are farther away. </li></ul><ul><li>Maps use a scale which is fixed for a particular map. It reduces the real distances proportionately to distances on paper. </li></ul>
