coordinate system wikipedia - EAS
- A coordinate system is a system that uses numbers or coordinates to determine the position of a point or geometric element within a geographic framework. This allows geographic datasets to use common locations for integration.

檢視所有 Wikipediahttps://en.wikipedia.org/wiki/Coordinate_systemIn geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space. The order of the coordinates is significant, and they are sometimes identified by their position … 查看更多內容

The simplest example of a coordinate system is the identification of points on a line with real numbers using the number line. In this system, an arbitrary point O (the origin) is … 查看更多內容There are often many different possible coordinate systems for describing geometrical figures.

The concept of a coordinate map, or coordinate chart is central to the theory of manifolds. A coordinate map is essentially a coordinate system for a subset of a given space with the property that each point has exactly one set of coordinates. More precisely, … 查看更多內容

In two dimensions, if one of the coordinates in a point coordinate system is held constant and the other coordinate is allowed to vary, then the resulting curve is called a coordinate curve. If the coordinate curves are, in fact, straight lines, they may be called … 查看更多內容
In geometry and kinematics, coordinate systems are used to describe the (linear) position of points and the angular position of axes, planes, and rigid bodies. In the latter case, the orientation of a second (typically referred to as "local") coordinate system, fixed to … 查看更多內容

The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various of spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordina…

Cartesian coordinate system - Wikipedia
https://en.wikipedia.org/wiki/Cartesian_coordinate_system- The adjective Cartesian refers to the French mathematician and philosopher René Descartes, who published this idea in 1637 while he was resident in the Netherlands. It was independently discovered by Pierre de Fermat, who also worked in three dimensions, although Fermat did not publish the discovery. The French cleric Nicole Oresmeused construction...

https://zh.wikipedia.org/wiki/坐標系- 數線
數線是最簡單的坐標系，用一個實數標示一個點在線上的位置。數線中會有一個原點O，以及單位長度及其方向。點P的坐標為從O到P的有號距離，坐標是正值或負值則依P點在原點的哪一側來決定。數線上每一個點都有唯一的坐標，每一個實數也都可以在數線上找到唯一的對應點。 - 笛卡兒座標系
笛卡兒座標系也稱為直角座標系，是最常用到的一種座標系。是法國數學家勒內·笛卡尔在1637年發表的《方法論》附錄中提到的。在平面上，選定二條互相垂直的線為座標軸，任一點距座標軸的有號距離為另一軸的座標，這就是二維的笛卡兒座標系，一般會選一條指向右方水平線稱為x …
