土地信息系统应用于存储空间物体的数据(如:G.建筑物、道路、电力网络等)。交互式检索主要是为了得到一个地图绘制在CRT屏幕上,因此,典型的查询是一个二维的范围查询,产生的所有数据需要绘制地图。 一种基于商业上可获得的DMBS(例如,G. DMBS-10),并给出了一些实际结果。所使用的方法在很大程度上依赖于控制存储记录的物理位置和根据邻域对数据进行聚类。
Land Information Systems shall be used to store data on objects in space (e. g. buildings, roads, electricity networks etc.). Interactive retrieval is mainly done in order to get a map drawn on a CRT screen; the typical query is therefore a two-dimensional range query which yields all the data needed to draw the map. A method to implement such a LIS based on a commercially available DMBS (e. g. DMBS-10 from DEC) is shown and some practical results are reported. The method used relies heavily on control of physical placement of stored records and clustering of data according to neighbourhood.
