The ellipsoid model is the first part of a spatial reference system definition.
椭圆体模型是空间引用系统定义的第一部分。
The second is that ArcExplorer requires all spatial columns to have a single spatial reference system assigned.
第二件事情是ArcExplorer要求所有空间列指定一个空间引用系统。
The second part of a spatial reference system is its projection, which defines how to lay out the Earth surface onto a 2-d surface.
空间引用系统的第二部分是投影，它定义了如何将地球表面放置在2 - d平面上。
Queries for other projections result in an error message asking the visitor to "request a supported SRS" (that is, a spatial reference system - essentially, the projection).
对于其他投影的查询会导致错误消息，要求访问者“请求一个受支持的SRS”(即一个空间参考系统—本质上，就是这个投影)。
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。
Such power has already been demonstrated by the standards and specifications on the Spatial Reference System (SRS).
这种能力已经通过空间引用系统(SRS)的标准和规范得到验证。
