Abstract

The invention relates to a temporal geographic information system (GIS) data management and presentation method. The temporal GIS data management and presentation method comprises the following steps: (1) storing temporal GIS data by an improved base state modified spatio-temporal data model; (2) recording the change relationship of a GIS space object by a change record sheet; (3) inquiring the change record sheet by an algorithm and establishing the tree history relationship; and (4) demonstrating the evolution relationship of the GIS space object by the representation mode of a temporal GIS player. By the temporal GIS data management and presentation method, the problems about the history relationship retrieval efficiency and presentation of the GIS space data under the condition of frequent dynamic change are solved.

Description

technical field

[0001] The invention relates to the whole life cycle management and historical relationship display of GIS spatial objects based on the improved ground state modified spatio-temporal data model, which describes the temporal change process of GIS spatial objects in the form of animation, and visually displays its historical evolution relationship, which is suitable for time Dynamic GIS data management and presentation. Background technique

[0002] With the continuous expansion of GIS application fields and the continuous increase of human needs, temporal GIS has attracted more and more attention from the industry[1]. : Sequence snapshot model, ground state modified spatio-temporal data model, spatio-temporal composite model, non-first normal form spatio-temporal data model, event-based spatio-temporal data model, etc. [2]. Among them, the ground state modified spatio-temporal data model is characterized by sampling at a preset time interval, and only storing...
