Map Projection
A projection which maps a sphere (or spheroid) onto a plane.
Map Projection Distortion
No map projection transformation can maintain scale everywhere. Angles, areas, distances and directions will be altered in the planar representation of the ellipsoidal earth.
Map Algebra
From now on we will assume all grids have been resampled if necessary to the same cell size and mesh. By "mesh" we mean simply the set of coordinates of cell boundaries.
Map Projection Standard
General Standard
Three Corporate standard map projections are recognized, including: ...
A map of this size is referred to as a ‘two degree sheet'. One, two degree sheet can be divided into four smaller quadrangles, each covering one degree of longitude and 1/2 degree of latitude (‘one degree sheet').
A map is a two-dimensional representation of a three-dimensional space. The science of making maps is called cartography.

Digital map provider Navteq announced December 7 a new technology agreement that will allow the company to more rapidly deploy innovative collection capabilities and accelerate the collection, creation, and storage of 3D map data and visuals.
Once the map is correctly registered, anything you digitize will appear in the correct geographic location.
NOTE: ps.map can read new option 'ROTATE:' from labels file, which specifies counter clockwise rotation in degrees.

of inexpensive Global Positioning System receivers has made position information available to many more people than ever before. With that comes the need to understand how coordinate systems work, and how to relate them to points on a map.
Map Analysis (Map Overlay)
This involves using the analytical capabilities of GIS to define relationships between layers of spatial data.
map An abstract representation of the physical features of a portion of the Earth's surface graphically displayed on a planar surface. Maps display signs, symbols, and spatial relationships among the features.
Map Densities
A density map lets you measure the number of features using a uniform areal unit so you can clearly see the distribution. This is especially useful when mapping areas, such as census tracts or counties, which vary greatly in size.
Map Projection Transformations
This functionality concerns the transformation of data in geographic coordinates for an existing map projection to another map projection.
Map Scanning
Optical scanning systems automatically capture map features, text, and symbols as individual cells, or pixels, and produce an automated product in raster format as described earlier in this section.
map scale : The extent of reduction needed to display a representation of the Earth's surface on a map.
map accuracy
(1) The closeness of results of observations, computations, or estimates of graphic map features to their true value or position.

Map Projection Method: Whether you understand this or not, all maps distort the spatial relationships among places.
Map - A graphic representation of geographically distributed phenomena. The information displayed may be in the form of symbols or signs.
North Arrow - The graphical representation of which direction north is on the map.
Map projection - "A method of representing the earth's three-dimensional surface as a flat two-dimensional surface.
Map Layer: Refers to the various 'overlays' of data, each of which normally deals with one thematic topic, such as breast cancer relative incidence, hazardous waste sites, or pesticide detections in the water supply.
Map Scale: The relationship existing between a distance on a map and the corresponding distance on the earth. A scale of 1 inch = 2000 feet can also be expressed as 1:24,000 (i.e., 1 inch on the map to 24,000 inches on the earth).

map scale
The reduction needed to display a representation of the Earth's surface on a map.
Map projection
The term map projection, or simply projection, is used by cartographers to describe any representation of the earth as a map.
Map Projection
A systematic conversion of locations on the Earth's surface from spherical to planar coordinates. Because the earth is three-dimensional, some method must be used to depict a map in to dimensions.
map -- a spatial representation, usually graphic on a flat surface, of spatial phenomena.
media -- the physical devices used to record, store, and (or) transmit data.
Map Display
A graphic representation of a geographic area and its features.
Map Scale: The relationship between distance on a map and the corresponding distance on the earth's surface.
Map overlay
The combination of two separate spatial data sets (points, lines or polygons) to create a new output vector data set. These overlays are similar to mathematical Venn diagram overlays.

Base Map
The base map is the most accurate spatial database within a data system. Base maps tend to be streets, parcels and other fundamental layers.
Base Map: The term 'base map' is used, throughout this site, to signify those GIS cartographies which chart a writer's movement through place over time.
Base Map - A map on which information can be placed for geographical correlation. Also can be used as a "base" upon which to build other information.
