Abstract: This paper describes the design and implementation of Regional Land Information Integration Model(RLI2M).Different Land Information System(LIS) cannot communicate with each other because of its inner workflows and data structure.Authors proposed a Regional Land Information Integration Model(RLI2M) to solve the problems which is caused by numerous rigid land resources management laws and regulations.By separating fundamental geo-spatial data and business data,the model can bring out various business applications on one map.By enlarging the definition of Operating Data Storage(ODS),RLI2M utilized a Land Information Operating Data Storage(L-ODS) to reduce redundant spatial data.Therefore,the developing of LIS would focus on business functions instead of data organization.The OLTP data structure design reduces the system respond time to a reasonable level.In addition,RLI2M integrates different business systems by using the message/return mechanism in UML even though each of them is different in inner workflows and data structure.Compound message contains simple orders,geometry features as well as attribute tables.That means business systems can send complex signals to each other for communications.In that case,RLI2M successfully strengthen central management which can prevent the disadvantages brought by independent business systems.This article also introduces an application based on RLI2M which was implemented in Liuzhou City,Guangxi Zhuang Autonomous Region.
