Preliminary Discussion on the Spatial Database Based on GML / KML

基于GML/KML的空间数据库研究

A basic KML file consists of a Document section that contains a name and description .

GoogleGeocoder服务将返回描述地址的KML。

Transforming the XML apartment listings into KML overlay data

However , for more complex data ( that is , data containing many more data points ), you will want to use a KML document .

然而，对于更复杂的数据（确切地说，包含更多数据点的数据）则需要使用KML文档。

Conclusions KML can treat cervical erosion to some extent and has anti-inflammatory and antipruritic effect .

结论抗糜灵具有明显的抑菌、抗炎、止痒作用，对宫颈糜烂有一定的治疗作用。

GEB reader Thomas has spent some time building an impressive collection of KML data for the race .

钩吻读者托马斯花了一些时间建立一个为比赛的KML数据令人印象十分深刻。

With a content-type of xml , your KML feed is ready for Google Maps .

有了xml格式的内容类型之后，GoogleMaps的KMLfeed就准备好了。

The KML file has been updated , so you can see the location of all of the fresh imagery .

新疆的喀纳斯湖部分终于更新了，可以找找有没有水怪了！

No other formats discussed in this article DXF , DWG , and KML have this restriction .

而本文中所讨论的其他格式DXF、DWG和KML均没有这个限制。

Because many people use Google Earth and Google Maps , a handy feature of the Layer object is the ability to export to KML format .

由于很多人都使用GoogleEarth和GoogleMaps，Layer对象的一个方便特性是可以导出成KML格式。

Save the KML data as a file on your local computer ( with a.kml extension or Google Earth won 't open it ) .

在本地计算机（要以.kml为扩展名，否则在GoogleEarth中无法打开）中将KML数据存为一个文件。

Each user is assigned the appropriate geographical area , and KML is created with designator fade depths based on message count per hour .

系统给每个用户都设定相应的地理区域，并且基于每个小时的邮件计数用指示器衰减深度创建KML。

Uploads_KML and uploads_Text for KML and text output formats

uploadsKML和uploadsText分别用于KML和文本输出格式

This way you can query the database , directly producing XML , and use XSLT to transform the returned data directly into KML that you can overlay on a map .

采用该方法，您可以查询数据库，直接生成XML，并使用XSLT将返回的数据直接转换为可以在地图上覆盖的KML。

Here the JavaScript creates the KML feed URL , appending a large random number to ( almost ) guarantee that Google fetches the fresh KML data .

在这里，JavaScript创建KMLfeedURL，并追加一个大的随机数（大多数情况）以保证Google读取最新的KML数据。

This thesis tries to meet this need by proposing a visualized knowledge modeling language called KML ( Knowledge Modeling Language ), which can be used to record tacit knowledge with complicated relationships .

该文正是针对这种需求，提出了可记录隐性知识的可视化知识建模语言（KnowledgeModelingLanguage，KML）。

Add KML , an XML language used to describe geographical information such as coordinates on the Earth , and you can overlay your own visual and textual data onto the maps .

KML是一种用来描述地理信息（例如地标）的XML语言，它可以将可视文本数据覆盖到地图上。

You provide this functionality by adding a few buttons to your HTML file with image tags : pan mode , draw mode , delete mode , and Save to KML .

您可以通过向HTML文件添加几个具有图像标记的按钮：panmode、drawmode、deletemode和SavetoKML，来实现这个功能。

With the incredible Google Earth interface , and the custom code above for creating KML , you can build your own time-availability maps for a wide variety of applications .

使用令人难以置信的GoogleEarth界面以及上面用于创建KML的自定义代码，您可以为各种应用程序构建您自己的时间-可用性地图。

In this article , you build a converter to translate these file formats into the more open ESRI shapefile or keyhole markup language ( KML ) formats .

在本文中，您将构建一个转换器来将这些文件格式转换成更为开放的ESRIshapefile或keyholemarkuplanguage（KML）格式。

In this article series , you 'll use server-side XSLT to transform a database of information into a KML file that you can feed to Google Maps and Google Earth to render custom data .

在本系列的文章中，可以使用服务器端的XSLT，将数据库信息转换为可提交给GoogleMaps和GoogleEarth的KML文件，从而显示自定义数据。

The KML document can specify geographic data including addresses , 3D coordinates on the Earth , and custom textual and visual data to be overlaid on maps or3D models of the Earth .

KML文档可以确定地址、地球上的3D坐标，以及地图上已覆盖的自定义文本和可视数据，或地球上的3D模型等地理信息。

When you provide KML data to Google Maps , you must use a URL that Google 's servers can access to retrieve the KML , so you must provide the server-side KML .

要为GoogleMaps提供KML数据，必须使用Google服务器有权访问的URL获取KML，所以必须提供服务器端的KML。

To enforce a refresh you need to specify a query parameter that changes each time , such as v = 2 , which specifies a different number each time you want Google to re-fetch the KML data .

为执行更新操作，需要指定一个每次都变化的查询参数，例如v=2，该参数每次都指定一个不同的数字，使Google重新读取KML数据。

With the database contents in XML format , you can use XSLT to transform the data into KML to produce data you can overlay on a map or import into Google Earth , which you 'll do in the next section .

因为数据库的内容是以XML格式表示的，所以可以使用XSLT将数据转换为KML格式，生成的数据可以在地图上覆盖，或导入GoogleEarth中，这将在下一节讨论。
