Embodiment Construction

[0034] In many remote sensing applications such as agriculture and the environment, the application of remote sensing image data is to use its multi-spectral characteristics to analyze specific ground conditions, such as the growth of crops and the degree of environmental pollution. In these application fields, the remote sensing image data formed through professional processing means, and the result information attribute carried by it is the core information displayed to the user. Since the results of this type of data application are usually limited in scope, and there are multiple periods of data display in the same location, it is necessary to support continuous addition of new data and replacement of original data, and the flexibility of the data is stronger; in addition, due to the attributes carried by the data Information is very important. Each image pixel can show the development curve of its data through multi-period data, and then show the growth trend of crops. The...

Abstract

The invention discloses a remote sensing image data space rapid visualization method based on lerc, and the method comprises the following steps: 1, obtaining a to-be-processed remote sensing image, and carrying out the orthographic and fusion processing of the remote sensing image; 2, carrying out format conversion on the obtained remote sensing image; and 3, scheduling the generated new file byusing a visual scheduling algorithm to realize rapid visualization of the remote sensing image data space. According to the method, the problem of rapid visualization of the remote sensing image on the premise that attribute information is not lost at the user side is solved.

Description

technical field [0001] The invention belongs to the technical field of remote sensing, and relates to a rapid spatial visualization method of remote sensing images. Background technique [0002] Remote sensing images are widely used in various industries, and remote sensing image data visualization is the most common application or display method, and it is an important service export of remote sensing applications. However, for high-resolution remote sensing images, especially push-broom satellite remote sensing images, the amount of single-scene data is often stored in the form of gigabyte-level large files. How to display a large amount of remote sensing image data in front of users is an important part of the application. [0003] At present, there are two mainstream methods for remote sensing image data visualization. One is to cut the image data and generate pyramid tile files, and realize multi-resolution display through the tile scheduling method related to the view...
