Embodiment Construction

[0064] The following examples of the present invention will be further described in detail. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0065] A method for processing multi-source map data, comprising the following steps:

[0066] (1) Compose the map request path by splicing parameters; including token token, map range bbox, multi-source map parameter maps, image size, image format and other parameter values;

[0067] (2) Calculate the ground resolution of slices or images (if static images such as slices or images are included), combine the image size parameters, determine the geographic range coordinates of the final returned map, and generate a processed business map to add to the multi-source map gather;

[0068] The specific steps are:

[0069] ①. If the requested multi-source map parameters do not include static images such as slices or images, you only need to calculate the geographic ...

Abstract

The invention relates to a multi-source map data processing method, which comprises the following steps of (1) forming a map request path by using splicing parameters comprising token parameters, map range parameters, multi-source map parameters, image size parameters and image format parameters; (2) calculating ground resolution comprising slices or image maps, determining geographical range coordinates of a finally returned map in combination with the image size parameters, and adding generated service images to a multi-source map set; (3) traversing and fusing all images in the multi-source map set to obtain a finally returned master service image. According to the method, a bottom layer space-isolated data structure is adopted, various images are directly fused, multi-source map images or service image data are integrated, and static images and dynamic images are accurately fused.

Description

technical field [0001] The invention belongs to the technical field of graphic data processing in geographic information systems, in particular to a multi-source map data processing method. Background technique [0002] With the implementation of the "SG186" project of the State Grid Corporation of China, the grid geographic information system platform was born. It is built on the "SG186" engineering integration platform to realize the structured The architecture is an enterprise-level power grid spatial information service platform that provides power grid graphics and analysis services for various business applications. Within the "SG186" integrated platform (including enterprise portal, data center, application integration and data exchange, etc.), build an open grid space information service platform that complies with service-oriented system architecture standards and is oriented to enterprise-level applications to realize various The unified and structured management ...
