  6. Topographic Symbols

  7. Colors on a Military Map (IAW FM 3-25.26 (C1), dated 30 August 2006) • Black: Indicates cultural (man-made) features such as buildings and roads, surveyed spot elevations, and all labels. • 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. • Blue: Identifies hydrography or water features such as lakes, swamps, rivers, and drainage. • Green: Identifies vegetation with military significance such as woods, orchards, and vineyards. • Brown: Identifies all relief features and elevation such as contours on older edition maps and cultivated land on red-light readable maps. • Red: Classifies cultural features, such as populated areas, main roads, and boundaries, on older maps.

  8. Military Grid Reference System The MGRS is the geocoordinate standard for NATO for locating points on the earth. The grid coordinate is made up of three parts: The Grid Zone Designation – one/two numbers followed by a letter identifies the UTM zone (numbers) and the latitude band (letter) The 100,000-meter Square Identifier – two letters identifying the series of 100,000-meter squares subdividing the UTM zones The Numerical Location – a series of even numbers to identify the location within the 100,000-meter square Grid Zone 100,000-meter 4 Digit 6 Digit 8 Digit 10 digit Designation Square Location Location Location Location State County Town Neighborhood Yard Tree 6o X 8o @ 10 KM2 1 KM2 100 M2 10 M2 1 M2 @ 675 KM2

  9. 100,000-meter Square Identifiers

  10. 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

Then Up ReadRight
