spatial knowledge

Getting geographic cognition from non-structural spatial description, transforming formal geography knowledge into customary natural language form, all of this is important pattern for conversion geographic information.

从非结构化的空间描述中获取地理认知，和将形式化的地理知识转换为习惯的自然语言形式，这是地理信息转换的重要模式。

So it is very necessary for making use of spatial data mining and knowledge discovery to mine aforehand unknown and potentially useful spatial patterns from spatial database.

因此，利用空间数据挖掘和知识发现从空间数据库中挖掘出事先未知的、却潜在有用的空间模式变得十分必要。

Though at first data mining comes from relation database and transactional database, with the special character of spatial data, mining knowledge from spatial database brings the attention of data mining researchers.

尽管数据挖掘最初产生于关系数据库和事务数据库，但由于空间数据的特殊性，从空间数据库中发掘知识很快引起了数据挖掘研究者的关注。

Grid GIS is an important part of SIG Grid GIS can be divided into five part in the view of grid, including Basal Grid, Spatial Data Grid, Spatial Information Grid ( in narrow sense), Spatial Knowledge Grid and Spatial Service Grid.

GRID GIS是SIG的重要组成部分，而GRID GIS从网格的角度又可以划分为基础网格、空间数据网格、空间信息网格（狭义）、空间知识网格和空间服务网格等。

Process model can express time and action in detail, yet it is apparently limited in dealing with spatial knowledge.

与GIS相反，过程模型细致表现时间和行为，在处理空间知识方面明显受限。

Model results showed that the area of knowledge stock not only had positive effect on region economy, but also drove economic growth in other areas. The spatial knowledge spillover effect existed, knowledge overflowed beyond the geographical boundaries of administrative areas.

模型结果表明，区域的知识存量不仅对本区域经济存在正面影响，更能带动其他区域的经济增长，空间知识溢出效应确实存在，知识溢出超越了行政区域的地理边界。
