Implementation of Object - oriented GIS Data Model with Topological Relations between Spatial Objects
Traditional GIS (Geographical Information System) data models are focused on the description of the data organizational structure and constraints from single aspect, which are the absence or little relevance of the hierarchy and connotation of data objects. These data models do not match the natural concept of humans about geographical spatial data and also failed to fully consider the spatia...

متن کاملDealing with indeterminacy in spatial descriptions.
How do people tackle indeterminate spatial descriptions, that is those descriptions for which several representations are possible? Take for instance the two following statements: B is to the left of A, C is to the left of A. This description is indeterminate because it is compatible with at least two possibilities: (1) C B A; (2) B C A. Studies on human reasoning have shown that people tend to...

متن کاملA Gis Database for Time-evolving Spatial Objects
In this paper, we have designed a data model for moving objects and implemented it. The moving objects are time-evolving spatial objects, that is, their geometries are dynamically changed as time varies. Generally, a GIS database stores and manages the spatial objects, of which geometries are rarely changed. The traditional GIS database, therefore, has a difficulty to manage the moving objects,...
