Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0022] Such as figure 1 According to the disaster information spatio-temporal database provided by the present invention, according to the viewpoint of the life cycle in the temporal GIS, the whole life cycle of the disaster is divided into three stages, corresponding to three disaster information databases respectively: the disaster current situation database storing the disaster current situation data, Disaster process database for storing disaster process data, disaster history database for storing disaster history data. The three databases are integrated into a disaster information space-time database, which also includes a logical change module, a space-time database index module, a unified coding module, a spatial position data management module and an attribute data management module.

[0023] From the perspective of earthquake disaster dat...

Abstract

The invention provides a disaster information spatial-temporal database, which comprises three disaster information databases including a disaster current simulation database, a disaster process database and a disaster historical database, wherein a unified coding module carries out layered coding on the received disaster information data, an attribute data management module and a space position management module guide in disaster information attribute data and space position data to the corresponding disaster information database, the disaster information data is transmitted among all disaster information databases through a logic conversion module, a spatial-temporal database index module builds updating index for the disaster information spatial-temporal database according to the time sequence, the logic conversion module and the spatial-temporal database index module form the basis of the disaster information spatial-temporal database, and the preparation is made for the disaster attribute management and maintenance, spatial-temporal logic index conversion and maintenance, statistics data entry, index and spatial-temporal inquiry. The disaster information spatial-temporal database solves the problems of lower work efficiency and high data redundancy during the realization of spatial-temporal data storage, management and historical review.

Description

technical field [0001] The invention relates to a database, in particular to a space-time database of disaster information. Background technique [0002] With the frequent human activities, there are various types of disaster information, including sudden geological disasters such as landslides, landslides and debris flows, and slow geological disasters such as land subsidence and seawater intrusion. Disaster spatial location database is the core of disaster management information system and the basis of disaster early warning and forecasting and disaster comprehensive risk prevention. However, looking at the existing massive disaster spatial location databases, we can find that these databases are basically static databases, which only describe a transient state of the data. When the data changes, new data replaces the old data, thus becoming another Transient, old data no longer exists, therefore, disaster information only stays at a certain stage of history, cannot refle...
