On A Planimetric Map The

A planimetric map presents simply the horizontal positions of the features represented. It is distinguished from a topographic map by the omission of relief, normally represented by contour lines. Sometimes, it is called a line map.

Topographic Map

topographic map

A topographic map portrays terrain features in a measurable way, likewise equally the horizontal positions of the features represented. The vertical positions, or relief, are unremarkably represented past contour lines on military topographic maps. On maps showing relief, the elevations and contours are measured from a specific vertical datum plane, commonly mean bounding main level. Meet more example at www.lib.utexas.edu

Photomap

photomap

A photomap is a reproduction of an aerial photograph upon which grid lines, marginal data, place names, road numbers, important elevations, boundaries, and gauge scale and direction have been added.

Joint Operations Graphics

joint-operations-graphics

Articulation Operations Graphics are based on the format of standard i:250,000 medium-scale military machine topographic map, but they incorporate additional information needed in joint air-ground operations. Along the north and east edges of the graphic, particular is extended beyond the standard map sheet to provide overlap with side by side sheets. These maps are produced both in footing and air formats. Each version is identified in the lower margin as either joint operations graphic (air) or joint operations graphic (footing). The topographic information is identical on both, merely the ground version shows elevations and contour in meters and the air version bear witness them in feet. Layer (elevation) tinting and relief shading is added equally an help to interpolating relief. Both versions emphasize air landing facilities (shown in purple), simply the air version has boosted symbols to identify aids and obstructions to air navigation.

Photomosaic

photomosaic-map A photomosaic is an assembly of aerial photographs that is commonly called a mosaic in topographic usage. Mosaics are useful when time does not permit the compilation of a more accurate map. The accuracy of a mosaic depends on the method employed in its preparation and may vary from just a skilful pictorial outcome of the ground to that of a planimetric map.

Terrain Model

terrain-model-map A terrain model is a scale model of the terrain showing features, and in big-scale models showing industrial and cultural shapes. Information technology provides a means for visualizing the terrain for planning or indoctrination purposes and for a briefing on assault landings.Some of the subjects covered are:

Terrain features

Drainage characteristics
Vegetation
Climate
Coasts and landing beaches
Roads and bridges
Railroads
Airfields
Urban areas
Electric ability
Fuels
Surface h2o resources
Ground water resources
Natural construction materials
Cross-country movements
Suitability for airfield construction
Airborne operations

Military Metropolis Map

military-city-map

A military machine city map is a topographic map (usually at ane:12,550 scale, sometimes up to 1:5,000), showing the details of a city. Information technology delineates streets and shows street names, important buildings, and other elements of the urban landscape important to navigation and military operations in urban terrain. The scale of a military metropolis map depends on the importance and size of the city, density of detail, and available intelligence information.If war machine maps are not available, employ substitute maps. The substitute maps can range from foreign armed services or commercial maps to field sketches. The NGA tin provide black and white reproductions of many foreign maps and can produce its own maps based upon intelligence.

Special Maps

special-maps

Special maps are for special purposes such as trafficability, communications, and assault maps. They are usually in the course of an overprint in the scales smaller than one:100,000 but larger than 1:i,000,000. A special purpose map is one that has been designed or modified to give information not covered on a standard map. The wide range of subjects that could be covered under the heading of special purpose maps prohibits, within the scope of this manual, more than a brief mention of a few important ones.If military machine maps are not available, utilize substitute maps. The substitute maps can range from foreign war machine or commercial maps to field sketches. The NGA can provide black and white reproductions of many foreign maps and can produce its own maps based upon intelligence.

Foreign Maps

foreign-maps

Foreign maps have been compiled by nations other than our ain. When they must be used, the marginal information and grids are changed to conform to our standards, if time permits. The scales may differ from our maps, just they practice express the ratio of map distance to ground distance and can be used in the same way. The legend must exist used since the map symbols near always differ from ours. Considering the accurateness of foreign maps varies considerably, they are usually evaluated in regard to established accuracy standards before they are issued to our troops.

Atlases

atlases

Atlases are collections of maps of regions, countries, continents, or the earth. Such maps are accurate only to a degree and tin can be used for general data just.

Geographic Maps

geographic-maps

Geographic maps provide an overall idea of the mapped area in relation to climate, population, relief, vegetation, and hydrography. They also bear witness the full general location of major urban areas.

Tourist Road Maps

Tourist route maps are maps of a region in which the primary means of transportation and areas of interest are shown. Some of these maps show secondary networks of roads, historic sites, museums, and beaches in item. They may contain road and fourth dimension altitude between points. The calibration should be carefully considered when using these maps. City/Utility Maps. Urban center/utility maps are maps of urban areas showing streets, water ducts, electricity and telephone lines, and sewers. Field Sketches. Field sketches are preliminary drawings of an area or piece of terrain. Aerial Photographs. Aerial photographs tin can exist used every bit map supplements or substitutes to aid you analyze the terrain, plan your road, or guide your movement.
