Design and implementation of Regional Land Information Intergration Model: An improvement

This paper describes the design and implementation of Regional Land Information Integration Model (RLI²M). RLI²M is used to solve the problems of land business systems´ incompatibility in China due to numerous rigid land resources management laws and regulations. By separating the fundamental geo-spatial data and land business data, this 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 system respond time was reduced 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. This article also introduces an application based on RLI²M which was implemented in Liuzhou, China.
