Definitions for **"Coordinate system"**

a system used to measure horizontal and vertical distances on a map. Data in GIS databases are assigned locations based on this system.

A reference device used to determine distance and direction in relative terms with respect to their location. The geographical coordinate system uses latitude and longitude to locate points on the earth; most other coordinate systems use regularly spaced grids which are placed on artificially derived planes.

A method of locating points or positions by assigning numbers to them. A three dimensional coordinate system has 3 axes and is used to locate a point or object in space.

Measurement system typically used for Geometry. All parts designed in C3P must start with a fully defined coordinate system.

proposal: we continue to support both a global (detector-level) coordinate system as well as a local coordinate system for individual detector elements ( e.g. strips (logical vs. physical?)). question: do we continue to use cm as our basic unit of length? question: do we continue to use the tpos (transverse position) variable. Is this useful? Is it well defined. A related question is the definition of the rotations X,Y,U,V. Perhaps, U and V should be redefined to straddle the X rather than the Y orientation.

Method of describing locations by columns and rows, or x and y values.

A PMAC coordinate system is a logical aggregate of PMAC motors. It is used to allow a synchronized movement of the motors. The PMAC allows up to 8 coordinate system definitions. A coordinate system may have 1 to 8 motor assignments. Only one motion program is allowed to run in a coordinate system.

A set of x-, y-, and z-axes, with a 0,0,0 origin. The entire Scene in EON has its own coordinate system. Each object within the Scene can have its own coordinate system defined by a Frame node

Any system of assigning planar or spatial positions to objects. Compare Cartesian coordinate system, polar coordinate system.

A particular kind of reference frame or system, such as plane rectangular coordinates or spherical coordinates, which use linear or angular quantities to designate the relative position of points within that particular reference frame or system.

A system of reference for locating points of the globe. Such systems use a regular grid which is measured in consistent units such as degrees. The two primary coordinate systems in use are the lat-long and UTM systems.

the system for assigning the numbers needed to define the location of a point in a reference frame

A recognised reference system for the unique location of a point in space. The Cartesian coordinate system and the system of latitude and longitude of the earth are examples of coordinate systems based upon Euclidean geometry. A coordinate system is usually defined by a map projection, a spheroid of reference, a datum, one or more standard parallels, a central meridian, and possible shifts in the X and Y directions to locate X,Y positions of point, line, and area features. A more complete explanation is available in the Standards Section.

A juxtaposition of two or more measurement scales which together define spatial locations in two or more dimensions.

Q uses a left-handed coordinate system with +x to the right, +y up and +z into the screen. P01

an organized system for describing 2- or 3-dimensional locations.

A method of locating points in the plane or in space by means of numbers. A point in the plane is located by its distances from both a horizontal and a vertical line called the axes. The horizontal line is called the x-axis. The vertical line is called the y-axis. The pairs of numbers are called ordered pairs. The first number, called the x coordinate, designates the distance along the horizontal axis. The second number, called the y-coordinate, designates the distance along the vertical axis. The point at which the two axes intersect has the coordinates (0,0) and is called the origin.

The system used to measure horizontal and vertical distance in a planimetric map. In a GIS, it is the system whose units and characteristics are defined by a map projection. A common coordinate system is used to spatially register geographic data for the same area. See Map Projection. erminous Having the same or coincident boundaries. Two adjacent polygons are coterminous when they share the same boundary (such a street centerline deviding two block).

In -dimensional space, a set of linearly independent vectors anchored to a point (called the origin). A group of coordinates specifies a point in space (or a vector from the origin) by indicating how far to travel along each vector to reach the point (or tip of the vector).

The use of Right Ascension and Declination to locate an object in the sky.

A system used to identify locations on a graph or grid. Latitude and longitude are an example of a coordinate system.

A fixed reference framework superimposed onto the surface of an area to designate the position of a point within it by using x and y coordinates. The State Plane Coordinate System and the system of latitude and longitude used on the Earth's surface are common examples.

A set of rules for specifying how coordinates are to be assigned to points.

A reference system for the unique definition for the location of a point in -dimensional space. Also called a spatial reference system. See also Cartesian coordinate system, geodetic coordinates, projected coordinates, and local coordinates.

an origin or reference point in 3D (XYZ) space for locating or orienting an object or CAD model.

Diagram which consists of two or more, mostly perpendicular axes (e.g. x and y), in which a function can be illustrated. Complex number Sum of a real part x and an imaginary part x which, since the real axis and the imaginary axis are perpendicular to each other, defines a point (x,y) in the complex plane. s=x+iy

A method of identifying a particular point in two or three dimensions by a systematic listing of the distances defined baselines or origins.

Any system where points are defined as a specified direction and/or distance from a reference point, measured with respect to defined axes.

What mapping system is used to represent postions. Some examples are latitude/longitude and state plane. The datalogger by default uses latitude/longitude. You can convert your data into the desired coordinate system using PFinder.

A graticule, or a Cartesian grid, in which points are located from two (or three) axes which intersect at a point.

a method for expressing location. In two-dimensional coordinate systems, locations are expressed by a column and row, also called x and y.

A rule of correspondence by which two or more quantities locate points unambiguously and which satisfies the further property that points unambiguously determine the quantities; for example, the usual Cartesian coordinates x, y in the plane.

A reference system used to measure horizontal and vertical distances on a planimetric map. A coordinate system is usually defined by a map projection, a spheroid of reference, a datum, one or more standard parallels, a central meridian, and possible shifts in the x- and y-directions to locate x,y positions of point, line, and area features. In ArcInfo, a system with units and characteristics defined by a map projection. A common coordinate system is used to spatially register geographic data for the same area.

A system with all the necessary components to locate a position in two- or three-dimensional space: that is, an origin, a type of unit distance, and axes.

(Also called reference frame.) Any scheme for the unique identification of each point of a given continuum. These may be points in space ( Eulerian coordinates) or parcels of a moving fluid ( Lagrangian coordinates). Newton's laws of motion do take different forms in different systems ( see inertial coordinate system, relative coordinate system). The geometry of the system is a matter of convenience determined by the boundaries of the continuum or by other considerations ( see Cartesian coordinates, curvilinear coordinates).

Any set of two or more magnitudes used to locate points, lines or curves. Commonly placed by using a horizontal axis (x-axis) and a vertical axis (y-axis).
