And for most map display engines, no matter what resolution the user needs to view the map, it is to directly load a large amount of basic pixel data of the image for display. For the map display engine, the huge amount of data loading will undoubtedly Increase the system load and reduce the loading speed, so that users cannot quickly view the map content

Abstract

The invention discloses a method for processing vector and raster slice data in an electric power GIS. The method comprises a collection step, a slicing step, a storage step, a request step, a first extraction step, a compression step, a first transmission step, a decompression step, a splicing step, a determination step, a detection step, a second transmission step, a merging step and a display step. By cloud storage, high system redundancy and security are provided and convenient storage is achieved. Due to the application of raster slice data and vector slice data, the access frequency of cloud storage is reduced, the server pressure can be effectively reduced, and the network load and the network delay are reduced.

Description

technical field [0001] The invention belongs to the technical field of electric power geographic information, and in particular relates to a method for processing vector and grid slice data in electric power GIS. Background technique [0002] With the continuous development of high-precision detection technology, more and more massive image data are gradually produced in various application fields, such as high-resolution satellite remote sensing image data in the field of remote sensing, high-definition medical images in the field of medicine, and laser points in the field of 3D scanning. Cloud data, etc., due to the characteristics of large data volume and rich information, the emergence of massive image data poses higher challenges for corresponding storage, management and display technologies. [0003] With the development of Internet technology, one of the main development directions of geographic information system is multivariate data access, which requires that in di...
