  8. Colors used on a Military Map • Black: Man-made features • Blue: Water features • Brown: Relief features and elevation on older or red-light readable maps • Green: Vegetation • Red: Man-made features • Red-Brown: Cultural features and non-surveyed spot elevations • Other: Occasionally other colors may be used to show special information and if used will be noted in the marginal information.

  41. Convex Slope Insert figure 10-6

  42. Contour lines around a slope Insert figure 10-6

  43. Measuring horizontal distance Insert figure 10-6

  44. Percentage of Slope in meters Insert figure 10-6

  45. Degree of Slope Insert figure 10-6

  46. Gradient Slope Insert figure 10-6

  47. Protractor(GTA 5-2-12, 1981)

  48. Determining Grid Coordinates • Select the correct scale on the protractor. • Place the horizontal scale on the grid line with the “0 mark” at the lower left-hand corner of the grid square. • Slide scale right into until the vertical scale intersects the center of your plot point. • Read right then read up

  49. EH 78 00 Then Up Four-Digit Grid Coordinates 1) Identify the 100, 000 Grid Square Identification Letters (in the Grid Reference Box). 2) Read Right to the last grid before your point. 3) Read Up to the last east-west grid below or before your point. Read Right
