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。
This application allows you to view the non-spatial attributes associated with each geometry in a separate frame.
这个内部函数以一个几何图形的WKT 表示（而不是几何图形本身）以及作为SVG属性的颜色和线宽为输入。
This internal function takes the WKT representation of a geometry as input -- not the geometry itself -- along with the color and line width for the respective SVG attributes.
在处理过程中，需要将数据库中的几何图形转换成它的SVG表示，并添加一些特定于呈现的属性，例如颜色和笔划宽度。
It is necessary to convert a geometry in the database to its SVG representation and adding some rendering-specific attributes like color and stroke-width in the process.
其他列中的值描述每个几何图形的属性（例如街道名称）。
Values in the additional columns describe properties (like street names) for each single geometry.
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。
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.
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 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.
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。
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.
这些特殊计算与那些是相似被使用在重覆叠盖的几何图形：交叉点被计算，点和连接被形成，拓扑结构建立，并且更新属性表格。
These particular computations are similar to those used in polygon overlay: intersections are computed, nodes and links are formed, topology is established, and attribute tables are updated.
每一个新的几何图形是由列表示在属性表格中的一个新对象。
Each new polygon is a new object that is represented by a row in the attribute table.
每一个新的几何图形是由列表示在属性表格中的一个新对象。
Each new polygon is a new object that is represented by a row in the attribute table.
