9. REASONS The instructions for any particular map sheet are located in the upper and lower margins of a map. All military maps are not the same, therefore, these instructions must be read each time a different map sheet is used.

10. AGENDA • Locate key marginal information on a military map. • Identify the five different colors used on a map and state what they represent.

11. SHEET NAME • Sheet Name is located in two places. Center of upper margin. Left side of lower margin. • Usually named for its outstanding cultural or geographic feature.

12. SHEET NUMBER • Located in the upper right margin. • Used as a reference number for that map sheet.

13. SERIES NAME • Located in the upper left margin along with the scale.

14. SERIES NUMBER • Located in the upper right margin and the lower left margin.

15. EDITION NUMBER • Located in the upper margin and the lower left margin. • Represents the age of the map in relation to other editions.

16. BAR SCALES • Located in the center of the lower margin. • They are rulers. • Used to convert map distance to ground distance.

17. ADJOINING SHEET DIAGRAM • Location varies with scale sizes. • All military maps contain a diagram which illustrates the adjoining sheets.

18. INDEX TO BOUNDARIES • Located in different places on different maps. • Shows the boundaries which occur within the map area.

19. GRID NOTE • Located in the center of the lower margin. • Gives information about the grid system used, the interval of grid lines, and the number of digits omitted from grid values.

20. PROJECTION NOTE • Located in the lower margin. • This projection system is the framework of the map.

21. GRID REFERENCE BOX • Located in the center of the lower margin. • Contains the instructions for composing a grid reference.

22. VERTICAL DATUM NOTE • Located in the center of the lower margin. • Designates the basis for all vertical control stations, contours, and elevations.

23. HORIZONTAL DATUM NOTE • Located in the center of the lower margin. • Indicates the basis for all horizontal control stations.

24. LEGEND • Located in the lower left margin. • Illustrates and identifies the topographic symbols used.

25. DECLINATION DIAGRAM • Located in the lower margin. • Indicates the angular relationships of the true, grid, and magnetic north.

26. USER’S NOTE • Located in the center of the lower margin. • Requests cooperation in correcting errors or omissions.

27. UNIT IMPRINT • Located in the lower left margin. • Identifies the agency that printed the map and the printing date.

28. CONTOUR INTERVAL • Located in the center of the lower margin.

29. SPECIAL NOTES AND SCALES • Various locations. • Under certain conditions, special notes or scales may be added to the marginal information to aid the map reader.

30. CLASSIFICATION • Located in the center of the upper and lower margins. • Certain maps require a note indicating the security classification.

31. STOCK NUMBER IDENTIFICATION • Located in the lower left margin. • All military maps published by the Corps of Engineers have stock identifications. • Used when requisitioning map supplies.

32. a • Where is the sheet name found? • Top center and lower left margin. • Where is the contour interval found? • Center of the lower margin. • Where is the declination diagram found? • Lower margin. • Where is the elevation guide found? • Lower right.

33. TOPOGRAPHIC SYMBOLS • Black • Blue • Green • Brown • Red

34. BLACK • Used to indicate cultural or man-made features. • Buildings, roads, spot elevations.

35. BLUE • Used to indicate water features. • Ponds, lakes, rivers, streams, intermittent streams.

36. GREEN • Used to indicate vegetation. • Woods, orchards, vineyards.

37. BROWN • Used to indicate surface features. • Contour lines.

38. RED • Used to indicate type or use of man-made features. • Main roads and built up population areas.

39. QUESTIONS

40. OBJECTIVE Action: Use marginal information to determine technical specifications about the map and to identify features on the map. Condition: Given a 1:50,000 scale military map. Standard: IAW FM 21-26

41. AGENDA • Locate key marginal information on a military map. • Identify the five different colors used on a map and state what they represent.

42. REVIEW Where is the grid reference box found? Located in the center of the lower margin. Where is the contour interval found? Located in the center of the lower margin. Where is the declination diagram found? Located in the lower margin.
