with Correct Answers
A map is defined as CORRECT ANSWER a graphic representation of a portion of the Earth's surface drawn to scale, as seen from above. It uses colors, symbols, and labels to represent features found on the ground.
-The ideal representation would be realized if every feature of the area being mapped could be shown in true shape. -The purpose of a map is to provide information on the existence, location, and distance between ground features, such as populated places and routes of travel and communication. It also indicates variations in terrain, heights of natural features, and the extent of vegetation cover.
-All operations conducted require maps; however, the finest maps available are worthless unless the map user knows how to read them.
Marginal Information CORRECT ANSWER A map is considered equipment. To use it properly, you should read the instructions. These instructions on the outer edges of the map are called marginal information. All maps are different so examine the marginal information on each map carefully.
Marginal Information (Top Margin 1-6) CORRECT ANSWER The top margin of the map helps you
to identify the specific area covered as well as the age and scale of the map. 1 Sheet Name (Top Margin) CORRECT ANSWER The sheet name is found in bold print at the center of the top and in the lower left area of the map margin. A map is generally named for the settlement contained within the area covered by the sheet or for the largest natural feature
located within the area at the time the map was drawn.
2 Sheet Number (Top Margin) CORRECT ANSWER The sheet number is bolded in the upper right
and lower left areas of the margin and in the center box of the adjoining sheets diagram, which is found in the lower right margin. It is used as a reference number to link specific maps to overlays, operations orders, and plans. For maps at 1:100,000 scale and larger, sheet numbers are based on an arbitrary system that makes possible the ready orientation of maps at scales of 1: 100,000, 1: 50,000, and 1: 25,000.
3 Series Name (Top Margin) CORRECT ANSWER The map series name is found in the same bold print as the sheet number in the upper left corner of the margin.
The name given to the series is generally that of a major political subdivision, such as a state within the United States or a European nation. A map series usually includes a group of similar maps at the same scale and on the same sheet lines or format designed to cover a particular geographic area. It may also be a group of maps that serve a common purpose, such as the military city maps.
4 Scale (Top Margin) CORRECT ANSWER The scale is found both in the upper left margin after the series name and in the center of the lower margin.
The scale note is a representative fraction that gives the ratio of a map distance to the corresponding distance on the Earth's surface. For example, the scale notes 1: 50,000 indicates that one unit of measure on the map equals 50,000 units of the same measure on the ground.
5 Series Number (Top Margin) CORRECT ANSWER The series number is found in both the upper right margin and the lower left margin. It is a sequence reference expressed either as a four-
digit numeral (1125) or as a letter, followed by a three- or four-digit numeral (M661; T7110).
6 Edition Number (Top Margin) CORRECT ANSWER The edition number is found bolded in the upper right area of the top margin and the lower left area of the bottom margin. Editions are numbered consecutively; therefore, if you have more than one edition, the highest numbered sheet is the most recent. This date is important when determining how accurately the map data might be expected to match what you will encounter on the ground.
Marginal Information (Bottom Margin 7-14) CORRECT ANSWER This portion of the map includes
information that helps to interpret the map. It provides correlation between actual terrain and man-made features and the map's topographic symbols. Some information found in the bottom
margin is repeated from the top margin.
7 Boundaries (Bottom Margin) CORRECT ANSWER The index to boundaries diagram appears in the lower or right margin of all sheets.
This diagram, which is a miniature of the map, shows the boundaries that occur within the map area, such as county lines and state boundaries.
8 Adjoining Sheets (Bottom Margin) CORRECT ANSWER Maps at all standard scales contain a diagram that illustrates the adjoining sheets. The diagram usually contains nine rectangles, but the number may vary depending on the locations of the adjoining sheets. All represented sheets are identified by their sheet numbers. Sheets of an adjoining series of the same scale, whether published or planned, are represented by dashed lines. The series number of the adjoining series is indicated along the appropriate side of the division line between the series.
9 Elevation Guide (Bottom Margin) CORRECT ANSWER This is normally found in the lower right margin. It is a miniature characterization of the terrain shown. The terrain is represented by bands of elevation, spot elevations, and major drainage features. The elevation guide provides the map reader with a means of rapid recognition of major landforms.
10 Declination Diagram (Bottom Margin) CORRECT ANSWER This is located in the lower margin of large-scale maps and indicates the angular relationships of true north, grid north, and magnetic north. On maps at 1:250,000 scale, this information is expressed as a note in the lower margin. In new maps, there is a note indicating the conversion of azimuths from grid to magnetic and from magnetic to grid next to the declination diagram.
11 Bar Scale (Bottom Margin) CORRECT ANSWER These are located in the center of the lower margin.
They are rulers used to convert map distance to ground distance.
Maps have three or more bar scales, each in a different unit of measure.
