Embodiment approach

[0054] In this embodiment, before the data slicing unit 112 performs cutting, in order to prevent the quality of the tile files obtained by subsequent tile cutting from being substandard due to the substandard quality of the remote sensing image itself, the data acquisition unit 114 acquires After the remote sensing image, the data processing unit 111 may perform image feature extraction on the remote sensing image.

[0055] Wherein, the image features include but not limited to at least one of band combination data, color depth, and projected coordinate system.

[0056] Any color image has multiple image channels. Generally speaking, according to the different types of satellites that shoot remote sensing images, remote sensing images include three image channels of R (red), G (green), and B (blue) or remote sensing images include R (red), G (green), and B (blue), N (near red) four image channels.

[0057] The color components in the R channel, G channel and B channel of th...

Abstract

The invention relates to a data processing method and device, a remote sensing data service platform and a readable storage medium. According to the invention, a tile file is cut and stored when a remote sensing data service platform acquires a remote sensing image, so that for the remote sensing data service platform, when the remote sensing data service platform acquires an access request, and tile cutting does not need to be performed on the corresponding remote sensing map temporarily so as to improve the access request response efficiency.

Description

technical field [0001] The application belongs to the field of data processing, and specifically relates to a data processing method, device, remote sensing data service platform and readable storage medium. Background technique [0002] With the widespread use of optical remote sensing images in various applications, more and more user groups have access to optical remote sensing image data. [0003] Generally speaking, the remote sensing data service platform is responsible for managing optical remote sensing images. When the traditional remote sensing data service platform manages the remote sensing image, it needs to obtain the remote sensing image provided by the remote sensing image provider and save it. When the remote sensing data service platform obtains the user's original remote sensing image viewing request for a certain area, it temporarily cuts the original remote sensing image according to the geographical space range of the area, thereby temporarily obtainin...
