Specialized formats are used to make the exchange and use of spatial data easier.
而专门的格式,将会使空间数据的交流和使用变得更加容易。
To address such widely differing requirements, DB2 implemented a hybrid approach when it comes to storing spatial data (or structured data in general).
为了解决千差万别的需求,DB 2实现了一种用于存储空间数据(或通常的结构数据)的混合方法。
With this article, you have all the necessary pieces to build your own Web applications and include spatial data in whichever way you like.
通过本文,您可以获得构建自己的Web应用程序并以任何喜欢的方式加入空间数据所需的全部信息。
You can easily list tables containing spatial data and select tables to display as a map using a combination of points, lines, and polygons.
可以很方便地列出包含空间数据的表,并可将表展示为由点、线、和多边形组成的图。
In order to manage spatial data in your database, the database must be enabled for spatial operations.
为了管理数据库中的空间数据,必须启用数据库的空间操作功能。
If you are familiar with spatial data and the grid index, the results are pretty much self-explanatory.
如果您熟悉空间数据和网格索引,那么结果就无需解释了。
Combining spatial data with text in search.
在搜索中将空间数据与文本合并。
GIS systems acquire and process spatial data describing the Earth's surface.
GIS系统可获得并处理描述地球表面的空间数据。
We already explained in a previous section the DB2-internal mechanism to store spatial data with widely varying size requirements.
在上一节中,我们解释了DB 2存储需求多变的空间数据的内部机制。
However, it is not so easy for spatial data given that the DB2 REORG TABLE command does not understand spatial indexes due to their complex nature.
然而,如果由于空间索引的复杂性质导致DB 2 REORGTABLE命令不理解空间索引,事情就不会那么容易了。
The effect will be that lobified spatial data will go to that table space.
这样做的效果是,大对象化的空间数据将被放入到那个表空间。
Now that you have an idea what can be achieved easily by combining SVG and spatial data in DB2 databases, the subsequent sections explain, in more detail, how I implemented the Web application.
现在,您知道了通过将svg与db2数据库中的空间数据相结合可以轻易地做到哪些事情,随后的小节将更详细地解释如何实现这个Web应用程序。
Therefore, the following queries calculate the size of the data based on the attributes of the spatial data types.
因此,下面的查询根据空间数据类型的属性来计算数据的宽度。
To find out, issue a spatial data query that reports all cities such that the bounding box of the tsunami line intersects the geographical city center.
为此,发出一个空间数据查询,搜索其中心包含在海啸线内的所有城市。
As you will see later, this distinction is important when it comes to encoding spatial data for search.
稍后您将看到,这一区分在为搜索编码空间数据时非常重要。
Instead, spatial data requires the rendering of maps.
相反,空间数据需要呈现地图。
You will notice that we access four attributes of the spatial data type ST_Geometry directly to not run into trouble with the generated column.
您会注意到,我们直接访问空间数据类型ST_Geometry的4个属性,以避免陷入生成的列的麻烦当中。
This sample application provides a generic framework that can deal with any spatial data residing in your DB2 database.
这个示例应用程序提供了一个通用框架,它可以处理DB 2数据库中的任何空间数据。
The script host.sql contains SQL statements that use federation to establish the connection to a remote DB2 for z/OS subsystem and to access three remote tables with spatial data through nicknames.
脚本host.sql包含一些SQL语句,这些语句使用联邦建立到一个远程DB2forz/OS子系统的连接,并通过昵称访问三个含空间数据的远程表。
