Affected by the deformation of maps, the accuracy of map data is also changed. Therefore, how to select a suitable map projection is an important subject.

受到地图变形的影响，地图资料的正确性则发生变化，因此如何选择适合的投影是极重要的课题。

Of its research mainly includes the preparation of maps, map projection, map finishing, map printing.

其研究内容主要包括地图编制、地图投影、地图整饰、地图印刷等。

As an important part of GIS platform, spatial reference system includes coordinate transformation and map projection, also named as Map projection transformation system.

GIS中的空间参照系统是GIS平台中的重要组成部分，内容包括各种坐标系统的转换和地图投影，故也称为投影变换系统。

This paper systemically elaborates map projection and map projective transformation.

1引言如何将地球空间信息通过一种数据交换表现在平面中，是地图投影研究的范畴。

Furthermore the computer implementation process and some key topics including map projection system, map projection parameters, algorithm optimization and error computation and control in the transformation process are discussed in this paper.

以此为基础，具体探讨了地图投影变换计算机实现的主要过程，讨论了地图投影体系、投影参数、算法优化和误差控制等投影变换计算机实现中的关键问题

A map projection in which quadrilaterals formed by meridians and parallels have an area on the map proportional to their area on the globe.

由子午线形成四边形并且把地球上的领域相应的投射在地图上形成的地图投影图。

As mentioned Live/Google maps use a Mercator projection, but although their datum is based on WGS84, they use a sphere instead of an ellipsoid.

上文所说Live Map / Google Map 使用墨卡托投影，但虽然他们的大地基准应该是基于WGS84的，他们用球体模型替换了椭球体模型。

Many analysis technology and space data are designed by the two-dimensional coordinates or plane coordinate, and used plain map projection methods to storage space coordinates, so many times we all need three-dimensional map projection to convert 3D geographical coordinates into the plane coordinates.

许多分析技术和空间数据都是针对二维坐标或平面坐标设计，以平面地图投影的方式来存储空间坐标，因此很多时候我们都需要利用地图投影将三维的地理坐标转换为平面坐标。

Mercator is the type of projection you see used on Live maps and Google maps, but as many often mistakenly thinks, they do NOT use WGS84 for the projected map, although WGS84 is used when you directly input longitude/latitude values using their API.

Live Map和Google Map都使用墨卡托投影，但并不像人们认为的那样他们使用WGS84基准面，虽然你在他们的API中输入的值是WGS84下的值。【译注：原因是WGS84基准面是基于椭球面的，而LiveMap和GoogleMap使用的是球面。另外，YahooMap使用的是等距圆柱投影。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
