Geometrical spatial dataintegration in geo-information management

Abstract

Geospatial information systems provide users with both absolute and relative locations of objects and their associated attributes. Partly, and to achieve this, the users need to use different geospatial data sets from various sources. The problem is that, there will inevitable exists some geometrical mismatch between these data sets and thus making it difficult to fit the data sets exactly with each other. This paper develops a conceptual mechanism for geospatial data integration that can identify, compare, determine differences and adjust spatial geometries of objects for information management.
