A sea island data management method and system

Abstract

The invention provides an island data management method. The method includes the steps of pre-sorting and storing all acquired data of islands according to different data types, storing space coordinates carried in the data; calling the data used for decreasing a geographic area required to display by a user according to the space coordinates of the geographic area, and organizing the called data of different types into a scene to be displayed in one layer. The invention further provides an island data management system which comprises a master database and a slave database. The master database is used for pre-sorting and storing all the acquired data of the islands, calling the data used for describing the geographic area according to the space coordinates, and organizing the called data of different types into the scene to be displayed in one layer. The slave database is used for storing thematic data, and storing the space coordinates carried in all data. The management method and system are low in management complexity.

Description

technical field [0001] The present invention relates to the technical field of sea island management, in particular to an island data management method and system. Background technique [0002] Island, in modern Chinese, refers to a small piece of land surrounded by sea water. Sea islands are the remote bases and fulcrums for human beings to develop the ocean, and they are the second marine economic zone, and they also have a special and important position in national land demarcation and national defense security. Therefore, it is an important research topic for technicians in this field to do a good job of monitoring and managing islands, and to reflect accurate, timely and comprehensive relevant data. [0003] In the process of island monitoring, a large amount of data will be generated, such as the topography data of the island itself obtained through remote sensing measurement, various business data for the development of the island, the name of the island, the area, a...

AI Technical Summary

Problems solved by technology

[0005] Since the island itself contains many types of data, this layer management data method needs to set up different layers. Even if only one layer is used for the same data type on a national or global scale, the number of layers is large. increases the complexity of management

However, if the same type of data uses the same layer in a larger range, when the user requests to display each scene in the range, the data of other scenes in the layer will also be called at the same time. For example, when the user only needs When learning the names of islands in the South China Sea on the electronic map, if the name data of the islands within China’s territorial waters are all set on the same layer, then when displaying the names of the islands in this scene, the relevant data of other islands will also be called, obviously. This part of the data also occupies the resource space of the cache, but it has no practical effect, which causes a waste of data resources

However, if the same type of data is divided into different layers according to the administrative region to which the island belongs, for example, according to the administrative region to which the island belongs, then multiple layers are added on the basis of multiple layers caused by different data types , the increase of layers will undoubtedly increase the complexity of data management

[0006] To sum up, the islands in the prior art are managed according to the data management method of layer management, and there are technical problems with high complexity
