每个数据地图保存单个表单实例的用户输入。
Each data map maintains the user input of a single form instance.
因此，此数据地图ID对每个用户和页面的组合而言也是惟一的。
Therefore, the data map ID is unique for each user and page combination.
在示例应用程序中，存储库所能存储的数据地图的实例是有限制的。
In the sample application, the repository has a limit of data map instances it can store.

当达到这个限值时，最旧的那个数据地图会从存储库中删除，以便进行垃圾收集。
When this limit is reached, the oldest data map is removed from the repository and becomes eligible for garbage collection.
这类数据地图的每个条目和元素都包含J SF输入组件的值，其ID是数据地图的键。
Each entry and element of such a data map contains the value of a JSF input component whose ID is also the key in the data map.
可以用plot - latlong创建的大多数有用的数据地图将把详细信息解析为详细的城市或郊区。
Most of the useful data maps that can be created with plot-latlong resolve details at the city or suburban area of detail.
原始的存储库和其副本均包含同样的数据地图对象，这是因为数据地图是不能修改的，这一点在本文稍后的部分介绍。
Both the original repository and its copy will contain the same data map objects, which is correct because data maps cannot be modified, as you'll see later in this article.
如果再引入最近以及将来的天气数据，我们就能制作出更详尽的数据地图，告诉农民们该如何、何时、何地种植庄稼了。
If recent and forecast weather data are added to the mix, detailed maps can be produced indicating exactly how, where and when crops should be grown.
这些副本都包含与原始存储库相同的数据地图对象，这一点没错，因为数据地图在用表单数据创建和填充之后不会被修改。
These copies, however, contain the same data map objects as the original repository, which is OK because data maps are not modified after being created and populated with the form data.
该文通过对分布式虚拟战场环境中仿真实体及其应用研究的开发应用，对光栅图像地图转化成矢量数据地图的方法进行研究。
In this article a method for converting raster image into vector drawing is introduced based on the application of simulated entity in distributed virtual battle field environment.
根据KrollOntrack公司的一项新研究，超过一半的英美企业没有“数据地图”，这种文件描述了什么信息正被存储，谁能接触它们。
More than half in America and Britain do not have a "data map", a document describing what information is being stored and who has access to it, according to a new study by Kroll Ontrack.
对象序列化是实现存储库持久性的一种最简单的方式，原因是datamaprepository类、所包含的数据地图以及它们的元素都是可序列化的。
Object serialization is an easy way for implementing the repository's persistence since the DataMapRepository class, the contained data maps, and their elements are serializable.
2005年版是第一份《2001年精神卫生地图集》的更新，包含了关于精神卫生资源最完整的全球数据。
The 2005 edition is an update of the first Mental Health Atlas 2001, and contains the most complete global data available on mental health resources.
这些信息与地图数据库结合起来。
对于这座世界上最大的体育场，到目前为止，我们使用的是世界地图册列表提供的数据，该列表根据各体育场公布的固定容量以及来自官方体育场网站更新的信息进行排名。
For the biggest stadiums in the world, we have used data supplied by the World Atlas list so far, which ranks them by their stated permanent capacity, as well as updated information from official stadium websites.
叫做等值线图的特殊地图使用地图的颜色来表示统计数据。
Special maps called choropleth maps use map color to represent statistical data.
他们可以为士兵提供一张可以显示即时地点数据的现场虚拟地图。
They can gather around a virtual map of the battlefield with live location data for their troops.
这个API上的额外的例程之后会使用纬度和经度数据来为地图上的这些位置构建呈现标记。
Additional routines on this API then use the latitude and longitude data to construct and render markers for these locations on the map.
完成之前的所有准备工作之后，现在可以将注意力放在根据空间数据呈现地图上来。
With all previous preparations being completed, you can now move on to render maps from the spatial data.
是现代科技的奇迹使这一突破成为可能。通过选择、排列数据，生成地图并呈现各种可能性。
The breakthrough has been made possible by the wonders of modern technology, in selecting and arranging the data, in generating the maps, and in presenting the possibilities.
因此，只能检索用户配置文件中在元素中包含有效位置数据的地图数据。
Therefore, map data can only be retrieved for user profiles that contain valid location data in the element.
相反，空间数据需要呈现地图。
比如，可以缓存地图数据来减少响应时间，但通常并不适合将搜索查询结果或者实时交通信息进行缓存。
For instance, it makes sense to cache map data to reduce response time, but it's often impossible or impractical to cache results of search queries or real-time traffic information.
这些数据还非常便于搜索地图或用矢量表示的各种图层。
These data also make it much easier to search the map or the vector representation's various layers.
地图数据使人“误入歧路”并不是惊奇。
移动位置服务已经越来越重要，底层的地图数据变成了有价值的战略资产。
As mobile services that involve location have become increasingly important, the underlying mapping data has become a valuable strategic asset.
例如，对于地理数据，(数据浏览器)会要求你提供那些地点使用的编码系统，要将数据放到地图上，这是必不可少的。
For example if it is geographic data then you are asked about the coding system used for the locations, essential for placing the data on a map.
