Abstract

Abstract: To solve the problem of dynamic changing and real-time monitoring of mining geological environment area,the dynamic multilevel base state and various granularities with amendments is proposed through time granularities and variable granularities storage factors are wholly integrated depending to the expression of time attribute in TGIS,so as to realize base state and history base state are quickly created in time granularities dynamic process.The five database structure and organization of spatiotemporal database are designed by combined with spatiotemporal data of a mining areas geological environment area,Then playback and advanced preview of area change scene are realized respectively by combing TGIS with video player and SQL.Finally spatiotemporal data of a mine geological environment type as example,the successful application states that the model can be real-timely monitored change of the geological environment areas,be improved the reclamation areas,and be realized the storage,reproduction and forecast of the mining geological environment area data.

Key words: dynamic multilevel base state, various granularities, amendments model, TGIS
