A map having background information, such as state, county, or city boundaries, upon which more detailed data is plotted.
A map which depicts fundamental information about the Earth's surface, such as landforms, drainage, landmark features and political boundaries. Many features are identified by geographical names or labels. Base maps usually come in a series and are used as a locational reference base for thematic information. Smaller scale regional reference maps are often derived from these bases. Topographic and planimetric maps are examples of base maps.
A map showing certain fundamental information, on which is compiled additional data of specialized nature. Also a map to which all other maps and GIS map layers are registered and re-scaled.
a map showing certain fundamental information on which can be compiled additional, specialized data.
A map used for the construction of other maps or which is used as a base by which other data is related to or referenced to.
A map designed for the presentation and analysis of data; it usually includes only the coordinates, geographical and major political outlines, and sometimes the larger lakes and rivers. Many modifications exist for specific uses throughout the geophysical sciences, such as the frequent inclusion of fixed reference points (or station positions). Mountains and contour lines are generally omitted, but high ground may be indicated by a single contour line and shading.
Mapped data which seldom change and which are used repeatedly for locational reference and control. It also establishes the lowest common denominator for map scale, coordinate system, and projection for other maps in a GIS database. Contrast with thematic map.
a map used for noting down land property and ownership of land.This map usually comes with predetermined reference points.These can be land features, state lines, county lines, township lines, and other distinctive markings that help to orient a property in terms of its immediate surroundings.
A map used in the development of other maps
a map that has a known acceptable level of accuracy that is accurate enough for the geometric control of other positional information, ( i
A map with reference points - such as state, county, township, or state and geodetic coordinate lines, or other features - on which land ownership data can be plotted.
Map of the community that depicts cultural features (roads, railroad, bridges, dams, culverts, etc.), drainage features, and the corporate limits.
A map showing certain fundamental information, used a base upon which additional specialized data are compiled.
A map showing planimetric, topographic, geological, political and/or cadastral information that may appear in many different types of maps. The base map information is drawn with other types of changing thematic information. Base map information may include major political boundaries, major hydrographic data, or major roads. The changing thematic information may be bus routes, population distribution or caribou migration routes.
Map containing field boundaries and data on significant visible surface features.
A map on which information can be placed for geographical correlation. Also can be used as a "base" upon which to build other information. Digital Orthophotography serves as an excellent base map due to its accuracy and visual characteristics.
See: map, base.
A map on which additional information can be marked. USGS maps, being in the public domain, are often used as base maps for private map publishers, particularly publishers of hiking or recreational topo maps. Also sometimes used to refer to the planimetric State Series Maps.
A term which varies in different applications, but, in general, refers to a map that depicts the fundamental map elements, such as streets, buildings, streams, etc., which are used frequently for locational reference. It is the control document from which various other maps in a geographic information system are developed.
A map containing geographic features used for locational reference. Roads, for example, are commonly found on base maps.
a map showing certain fundamental information such as parcel or municipality boundaries, used as a base upon which additional data(hydrology, utilities, sewer lines, etc.) can be presented; a source map.
A map with all the important information about the Earth's surface - like landforms, drainage, landmark features and political boundaries. Most of them have labels or names. They come in a series Compass and are used as a reference for thematic information. Examples of base maps include topographic and planimetric maps.
A map containing geographic information for purposes of referencing study data and displaying its distribution and inter-relationships.
A map containing visible surface features and boundaries, essential for locating additional layers, or types, of georeferenced information.
a simple map that shows the boundaries of a field or section and information about any unique feature (sinkholes, or streams).
A set of topographic data displayed in map form providing a frame of reference or contextual information to the user.
A map that contains geographical reference information on which attribute data may be plotted to make thematic maps.
Mapped data that seldom changes and is used repeatedly.
Planimetric line maps used to plan or to compile data for production of specialized maps.
Some GPS units come equipped with a permanant installed basemaps. Coverage includes water bodies, urban centers, road systems, airports and political boundaries. Depending on the user's requirements, basemaps are available for many world wide regions.
A map that shows only essential geographic references (such as roads, towns, section lines, etc.) on which additional information is plotted: for example, a topographic map on which geologic information is recorded.
A map containing the background upon which geographic data is overlayed and analyzed. Basic representation of a region of the earth as it would appear if viewed from above. Portrays basic reference information onto which other information of a specialized nature is placed. Usually shows the location and extent of natural earth surface features and permanent man-made objects. Contains basic digital survey control and topographic elevation reference framework for integrating all of the other map features of a particular area.
A map upon which information may be placed for comparison or geographical correlation.
Map content including geographic, physical, cultural, political, and statistical features for locational reference.
