Address-Point is a mapping/ GIS data product supplied by the United Kingdom's national mapping agency, Ordnance Survey. It is based on the UK’s postal mail organisation, the Royal Mail®, list of postal addresses, postal address file (PAF®). The most significant difference between Royal Mail® list and address-point is that address-point includes the geographic coordinates of each postal address. This enables users to map the individual addresses. ...more on Wikipedia about "Address-Point"
Aerial photography is the taking of photographs from above with a camera mounted on an aircraft, balloon, rocket, kite, skydiver or similar vehicle. It was first practiced by the French airman Nadar in 1858. The use of aerial photography for military purposes was expanded during World War I by aviators such as Fred Zinn. ...more on Wikipedia about "Aerial photography"

Bathymetry is the underwater equivalent to topography. A bathymetric map gives the depth contours of the soil, rock, sand, etc. at the bottom of a body of water such as an ocean or a lake. In addition to this, a bathymetric chart provides navigational information. ...more on Wikipedia about "Bathymetry"

Cartography or mapmaking (in Greek chartis = map and graphein = write) is the study and practice of making maps or globes. Maps have traditionally been made using pen and paper, but the advent and spread of computers has revolutionized cartography. Most commercial quality maps are now made with map making software that falls into one of three main types; CAD, GIS, and specialized map illustration software. ...more on Wikipedia about "Cartography"

A choropleth map ( Greek χωρα, area, region + πληθαίνω multiply) is a map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map, such as population density or per-capita income. It provides an easy way to visualize how a measurement varies across a geographic area. ...more on Wikipedia about "Choropleth map"
A contour line (also level set, isopleth, isogram or isarithm) for a function of two variables is a curve connecting points where the function has a same particular value. A contour map is a map showing contour lines. ...more on Wikipedia about "Contour line"
In geographic information systems, a coverage is a mapping of one aspect of data in space. It represents a "domain" (the universe of extent) in terms of characteristics expressing a range of values. For example: a satellite image derived from remote sensing might record varying degrees of light pollution. ...more on Wikipedia about "Coverage data" Inform your friends about www.shortopedia.com
Sir Robert Dudley's Dell'Arcano del Mare is the earliest printed sea atlas to cover the entire world, and the first made by an Englishman, and the first to use the Mercator projection. It collects all the naval knowledge of its time. It was first published in Italian at Florence in 1645, then again in 1646 in three folio volumes, and which is remarkable for its inclusion of a proposal for the construction of a navy in five rates which Dudley designed and described. It was reprinted in Florence in a two volume folio edition in 1661 without the charts of the first edition. ...more on Wikipedia about "Dell'Arcano del Mare"

A digital raster graphic (DRG) is a digital image resulting from scanning a paper USGS topographic map for use on a computer. DRGs created by USGS are typically scanned at 250 dpi and saved as a TIFF. The raster image usually includes the original border information, referred to as the "map collar". The map file is UTM projected and georeferenced to the surface of the earth. DRG's are regularly used in GIS applications. ...more on Wikipedia about "Digital raster graphic"
A distortion is the alteration of the original shape (or other characteristic) of an object, image, sound, waveform or other form of information or representation. Distortion is usually avoided and unwanted because it skews signals. However, there are acceptions, such as electric guitars (where disortion is often wanted through the amplifier),analog tape, and vaccum tubes (both offer pleasing harmonics with slight distortion). ...more on Wikipedia about "Distortion"

Eartha is the name given to the world's largest rotating globe (excluding the Earth itself), located within the headquarters of the Delorme mapping corporation in Yarmouth, Maine. The globe weighs approximately 5,600 pounds, and has a diameter of over 41 feet(12.5 m). This gives it a scale of 1:1,000,000, on which one inch represents 16 miles, one millimetre represents one kilometre. The globe was completed on July 23 1998, and it uses a composite database built from satellite imagery, shaded relief, colored bathymetry, and information about road networks and urban areas. ...more on Wikipedia about "Eartha"
