Design of geographic information data storage system for land change survey based on ArcGIS

In order to realize the unified storage of geographic information data of different structural types of land change survey, a geographic information data storage system of land change survey based on ArcGIS is designed. As for the system hardware, data server, data collector and data storage are designed to form the system hardware structure. The software part sets the group key, stores and processes the geographic information data of land change survey, and completes the design of data storage system. The experimental results show that the storage performance of the designed system is good, with excellent user interface, response speed, data synchronization, security, expansibility and compatibility. At the same time, the data storage processing delay of the system in this paper is low, which can meet the needs of large-scale geographic information data storage.
