reference system

基本解釋

The ellipsoid model is the first part of a spatial reference system definition.
橢圓體模型是空間引用系統(tǒng)定義的第一部分。
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.
空間引用系統(tǒng)的第二部分是投影，它定義了如何將地球表面放置在 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).
對于其他投影的查詢會導致錯誤消息，要求訪問者 “請求一個受支持的 SRS”（即一個空間參考系統(tǒng) — 本質上，就是這個投影）。

If you're an inertial observer, then in your system of reference, objects left at rest will remain at rest.
如果你是慣性觀察者,那么在你的參考系內,靜止的物體會保持靜止
