A layer is a collection of spatial objects (and their non-spatial attributes) of a common type.
一个层是具有共同类型的空间对象(及其非空间属性)的一个集合。
This application allows you to view the non-spatial attributes associated with each geometry in a separate frame.
这个应用程序允许在一个单独的框架中查看与每个几何图形相关的非空间属性。
To that end, all those non-spatial attributes are processed in function render_geometries and encoded in the XHTML code.
为此，所有那些非空间属性都在函数render_geometries中处理，并编写到XHTML代码中。
We show the queries in the upper left frame, the rendered SVG output in the lower frame, and the non-spatial attributes in the upper right frame.
左上角的框架显示查询，下面的框架显示sVG输出，右上角的框架则显示非空间属性。
The connection between a geometry and its non-spatial attributes is established by "opening" the SVG element of a geometry and adding onmouseover and onmouseout attributes.
几何图形与它的非空间属性之间的连接是通过 “打开” 几何图形的SVG元素，并添加onmouseover和onmouseout 属性来建立的。
The final piece of the small Web application that I want to describe is the frame that shows non-spatial attributes whenever you move the mouse over a particular geometry.
对于这个小型的Web应用程序，我要谈到的最后一部分是用于显示非空间属性的一个框架，每当将鼠标移到一个特定的几何图形上时，该框架就显示它的非空间属性。
Along the same lines, you also collect the non-spatial attributes for each geometry and encode it in the XHTML document so that they do not have to be retrieved from DB2 whenever they are accessed.
除了这些线之外，还需收集每个几何图形的非空间属性，并编写到XHTML文档中，而不必在访问到它们时从DB 2中检索它们。
