FEATURE MANAGEMENT FOR WEB MAP TILE SERVICES

In accordance with one embodiment of the invention, a method ensures, by a web map tile service, the updated display of features. In this method, a web map tile service database receives a change to afeature on a map and a server system identifies rendered tiles in a cache that are impacted by the change to the feature. The server system invalidates the identified rendered tiles in the cache by,for example, removing them. 根据本发明的一个实施方式，提供了一种通过web地图图块服务来确保特征的更新显示的方法。在该方法中，web地图图块服务数据库接收针对地图上的特征的变化，服务器系统识别缓存中的、受针对所述特征的变化影响的渲染图块。所述服务器系统通过例如删除所述缓存中的所识别的渲染图块来使这些图块无效。
