What is a map?
A graphic representation of a portion of the Earth's surface drawn to scale, as seen from
above.
In the division, who is responsible for map requisitions and distribution?
This is the responsibility of the G2 section.
Military maps are categorized by what two things?
Scale and type
What is meant by the "scale" of a map?
The scale is expressed as a representative fraction (RF) and gives the ratio of map
distance (numerator) to ground
distance (denominator).
NGA maps are classified by scale into what three categories?
• Small scale (1:1,000,000 and smaller)
• Medium scale (larger than 1:1,000,000 but smaller than 1:75,000)
• Large scale (1:75,000 and larger)
What is the standard "small scale" map and what is it used for?
, 1:1,000,000; it is used for general planning and for strategical studies
What is the standard "medium scale" map and what is it used for?
1:250,000; used for operational planning.
What is the standard "large scale" map and what is it used for?
1:50,000; used for tactical, administrative, and logistical planning.
What are some of the different TYPES of maps produced by the NGA?
1. Planimetric - no contour lines
2. Topographic - has contour lines
3. Digital Maps - a visual representation depicted by electronic data compiled into a
virtual image
4. Digital city graphic - shows the locations of important buildings, airfields, military
installations, embassies,
hospitals, schools and other structures
5. Photomap - map information (grid lines, scale, etc) superimposed on an aerial
photograph
6. Joint Operations Graphics (JOGs)
7. Photomosaic - assembly of aerial photographs
8. Terrain Model - scale model of the terrain
9. Military City - map showing the details of a city, with street names, important
buildings, and other elements of
the urban landscape important to navigation and military operations in urban terrain.
10. Special - special maps that usually include information not found on standard maps
Where does a map get its name and where is the "sheet name" located?
