Paper Abstract

This article discusses the synchronous update mechanism and implementary policy for real-time network of the land survey database based on multi-level distributed heterogeneous structure of "state-province-city-county", and to design and realize the incremental update network system in application to web service model and incremental updating mode of the land survey data. The main procedure of real-time network synchronous update policy in this article includes: data standardization transition, web services network asynchronous transmission, data processing and checking, spatial entity data increment updating. This paper also experiments, tests and validates the model method and updating policy as Laoren village land block data update for an example.
