土地数据集成方法探讨

The Study for Integration Method of Land Data

土地信息系统的迅速发展和广泛应用导致了土地空间数据多源性的产生,为土地数据综合利用和数据共享带来不便。探讨土地空间数据多源性的产生和表现,指出多数据格式是多源土地数据集成的瓶颈;提出了多源空间数据集成的原则与方法,展望了土地多源数据集成的发展方向,并将其在土地管理中的应用做了有益的探索。

The quick development of land GIS and its wide use produce the multi-sources land spatial data which makes the comprehensive utilization and information share of land data very difficult. In this paper, we discuss the appearance of land spatial data, pointing out multiple formats is the bottle neck for integration of land spatial data. Then, we put forward the principles and methods for multi-sources spatial data integration and prospect the development orientation. At last, we explore application for land management.
