Abstract

The invention belongs to the technical field of geographic information, and provides an online backtracking and comparison method for two-dimensional spatial-temporal geographic information. The method provided by the invention has the advantages that map services can be rapidly read at a web end, so that the function of online efficient backtracking of the two-dimensional spatial-temporal geographic information can be achieved, and the problem of data waiting during display switching among geographic information services at different moments can be avoided; and the function of change comparison among the geographic information services at the different moments and for a same region is achieved, so that the city planning personnel and the land planning personnel can more conveniently analyze city development changes, and social applications of the geographic information can be further promoted.

Description

technical field [0001] The present invention relates to the technical field of geographic information, in particular to an online backtracking and comparison method for two-dimensional spatiotemporal geographic information, which is used in geographic information production and application units, such as planning departments, land departments, surveying and mapping departments, urban design departments, and the like. Background technique [0002] Traditional geographic information system applications only involve two aspects of geographic information: spatial dimension and attribute dimension, so it is also called static GIS (Static GIS). However, in many application fields, space objects change with time, such as environmental detection and measurement of PM2.5 changes in a certain area, distribution of materials in disaster relief areas during earthquake rescue, and statistical analysis of meteorological observation data in various regions during weather forecasting Such t...
