Remote sensing image data processing system and data processing method based on mobile terminal

Abstract

The invention discloses a remote sensing image data processing system and data processing method based on a mobile terminal. The mobile terminal includes a wave band operation module, a color composition module and an image classification module. The remote sensing image data processing method based on the mobile terminal includes the steps: a server terminal releases a plurality of single wave band images and vector data; and the mobile terminal receives the plurality of single wave band images and vector data and performs wave band operation, image classification and color composition on theplurality of single wave band images and vector data. The remote sensing image data processing system and data processing method based on the mobile terminal can save frequent interaction between a client and the server terminal, and can save the computation resource of the server. Besides, in the environment (such as the field) that the network condition is relatively worse, the remote sensing image data processing system based on the mobile terminal can realize real-time display and processing of the image data, can improve the user experience, has relatively lower demand for hardware configuration for the system, is relatively higher in portability, and is relatively lower in the technical cost as the remote sensing image data processing system is completed by means of the open sourcetechnology, so that the remote sensing image data processing system can be widely applied to geological survey, field rescue and other works with relatively higher instantaneity.

Description

technical field [0001] The invention relates to the field of remote sensing image processing, in particular to a remote sensing image data processing system and data processing method based on a mobile terminal. Background technique [0002] With a series of satellites launched by NASA's Global Observing System and other international and commercial projects, remote sensing imagery data has gradually become an important data source in earth science research. In order to better apply remote sensing image data, many scholars regard Web Geographic Information System (WebGIS) as an effective tool to realize the display, spatial analysis, data mining and data sharing of remote sensing image data. WebGIS is a new technology that uses Internet technology to expand and improve traditional GIS, and is an ideal solution to realize GIS interoperability. WebGIS makes up for the shortcomings of traditional GIS in data sharing. Its core is to embed the application system of HTTP standard...

Problems solved by technology

[0004] However, in the existing WebGIS solutions and application cases, a large amount of data analysis work is done on the server side, and the main task of the mobile terminal is to obtain and display the massive remote sensing image data released by the server side through the network in the user interface. , which has higher requirements on the network conditions of the user's environment

The transmission of massive high-resolution remote sensing data will be affected by network bandwidth, delay, etc., which reduces user experience; Efficient use of computing resources on the mobile side
