Abstract

The embodiment of the invention provides a remote sensing image automatic updating and historical backtracking method and device based on single service. The method comprises the following steps: acquiring first image information of a new image and second image information of an original image in a database; comparing the first image information with the second image information, and determining the overlapping condition of the new image and the original image; and storing the new image in the database in a corresponding storage mode according to the difference of the overlapping conditions, wherein the storage mode comprises the step of changing a data label of corresponding slice data of the original image in the database. Through the scheme of the embodiment, the development efficiency of the WebGIS is improved, and the development cost and the maintenance cost are reduced.

Description

technical field [0001] This article relates to the field of image map services, especially a single-service-based remote sensing image automatic update and historical retrospective method and device. Background technique [0002] my country is currently developing rapidly in the aerospace industry, and there are abundant satellite images, especially in places with rapid economic development or frequent geological disasters, satellite images are particularly abundant, and changes can be detected through satellite images. At the same time, in the Internet age, images are mostly displayed in the form of map services. Under the traditional map service, it is mostly implemented by publishing multiple image services. [0003] In this context, the following problems arise: [0004] 1) Affecting the display of the front-end system, when the data is updated, the front-end system needs to be shut down, and the new service address is updated to the front-end system configuration. ...
