Abstract

The invention relates to the field of GIS space-time data model building, in particular to a pan-knowledge space-time object expression database building method. In order to solve the problems that an existing space-time data model has scarce capacity of space-time integrating expression and four-dimensional space-time data expression, the spatial or temporal continuity phenomenon cannot effectively expressed, and the geometrical shape and the gesture of a space-time object cannot be expressed, the pan-knowledge space-time object expression database building method comprises the steps that a space-time object expression data model is built, wherein the types of the space-time object expression data model comprise a rigid motion model type, a fluid motion model type, a field model type, a quasi-dynamic model type and a static model type; space-time data is collected; according to the type of the space-time data, the space-time data is modeled by using the space-time object expression data model, and the modeled space-time data is stored in a database. The method is suitable for space-time data modeling.

Description

technical field

[0001] The invention relates to the field of GIS spatio-temporal data model construction, in particular to a method for establishing a pan-knowledge spatio-temporal object expression database. Background technique

[0002] Since US Vice President Al Gore proposed the Digital Earth in 1998, the MIT Automatic Identification Center (Auto-ID), established in 1999, first clarified the basic meaning of the Internet of Things (everything can be connected to the Internet) and in 2006, the CEO of Google made the first Since the concept of cloud computing was put forward, the application demand of human beings for information platforms such as smart earth and smart city is growing rapidly. In 2008, IBM first proposed the concept of smart earth, which is the organic integration of digital earth and the real world through the Internet of Things, and has been widely used in the fields of national defense and national security. The smart city is based on the digital city,...
