摘要： The present invention relates to a geographic information system having editable maps. In an embodiment, a system provides editable maps. The system includes an edit layer dataset that stores geocoded data. At least a portion of the edit layer dataset is edited by a user. The system also includes a base layer dataset that includes trusted geocoded data and a moderation module that receives a change in the edit layer dataset. The moderation module determines whether the change is reliable and promotes the change in the edit layer dataset to the base layer dataset if the change is reliable.

摘要： Aspects of the invention relate generally to accessing, storing, and processing vector data to represent various geographical features such as roads, rivers, lakes, countries, continents, and oceans on one or more maps. More specifically, the vector data may be pre-simplified for rendering at different zoom levels. The simplification process is based on removing vertices from vector data in order to reduce the number of points in a given polygon or line. As this process is very expensive in terms of time and processing power, the system and method allow for estimation of the proportion of vertices which that would be removed from the original geometry. Based on this estimation, one may decide whether or not the simplification is worth the effort to compute and store the simplified data.
摘要翻译：本发明的方面一般涉及访问，存储和处理矢量数据以在一个或多个地图上表示各种地理特征，例如道路，河流，湖泊，国家，大陆和海洋。更具体地，矢量数据可以被预先简化，以便在不同的缩放级别呈现。简化过程基于从矢量数据中删除顶点，以减少给定多边形或线中的点数。由于该过程在时间和处理能力方面非常昂贵，所以系统和方法允许估计将从原始几何中去除的顶点的比例。基于此估计，可以决定简化是否值得为计算和存储简化数据而努力。

摘要： Aspects of the invention relate generally to updating of interconnected features stored in a repository while maintaining highly consisting views of the repository data. More specifically, the invention relates to updating some features in bulk while providing for incremental updates for other features which are not completely independent of the bulk edits. The bulk edits are grouped into stages or “epochs” associated with various manageable states, including, for example, a building state, an approval state, a live state, and an abandoned state. The current view of the data is thus based on the status of each of the epochs. At the same time, incremental edits may be performed where the incremental edits are independent of the current live bulk epoch. This allows the system to maintain consistent views of the data until an entire group of features moves into the live state.
摘要翻译：本发明的方面一般涉及存储在存储库中的互连特征的更新，同时保持储存库数据的高度组合的视图。更具体地，本发明涉及批量更新某些特征，同时为不完全独立于批量编辑的其它特征提供增量更新。批量编辑分为与各种可管理状态相关联的阶段或“时期”，包括例如建筑物状态，批准状态，活动状态和废弃状态。因此，数据的当前视图基于每个时期的状态。同时，可以执行增量编辑，其中增量编辑与当前活体纪元独立。这允许系统保持数据的一致视图，直到整个特征组移动到活动状态。
