Abstract

The invention discloses a data producing, organizing, storing and accessing method of an electronic atlas system. The method comprises the steps of: acquiring grid pictures; performing naming; entering metadata; establishing a description folder, a legend folder, a thumbnail folder, a picture folder and an index file, and organizing production of an atlas; cutting a single map into map tiles; dividing map products into single maps, map pairs, series maps and atlas; uploading the map products to the cloud server to establish the atlas database index; downloading the map tile data into the innercard or directly pre-loading the data into the inner card; putting different map tile data into different wild cards; carrying out map inquiry and reading as required. The invention greatly improvesthe retrieval speed of map data search, reduces the storage pressure of mobile equipment, enables people to read map with or without a network, and realizes the purpose of dynamically opening and sharing the atlas data based on the background data center.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to a data production, organization, storage and access method of an electronic atlas system. Background technique [0002] With the application and development of geographic information technology, map products are in the process of converting paper maps to electronic maps. Most maps are based on raster data format. Raster format maps not only have a large amount of data, but also have a large delay in user interaction operations. The organization, storage, access and reading of map data have become the core technical issues of the application system. At this time, A more efficient and flexible data storage and interaction method is needed to improve user interaction experience; for massive map data, how to store massive data, how to manage massive databases, establish an efficient data storage access mechanism, and improve the performance of the system in response to user data operat...
