摘要
地理信息系统的迅速发展和广泛应用导致了空间多源数据的产生,给数据的集成和信息共享带来不便。不同数据源,不同数据精度和不同数据模型的地理数据融合理论与方法的研究,对于降低地理数据的生产成本,加快现有地理信息更新速度,提高地理数据质量有着重要的现实意义。本文对多种空间数据融合的原理与方法进行了讨论,给出了空间数据融合的多种应用,并对数据融合的发展方向进行了展望。
Application of Geographical Information Systems (GIS) make the appearance of multi-resources data, but make the data integration and share more difficult. By spatial data integration, the difference caused by multi-resources data, spatial data model, classification and geometry position are eliminated, Meanwhile, data integration can reduce the cost of product, fasten the update of geographical information, and improve data quality. The principles of multi- resources geospatial data integration are discussed in this article, and its applications are given out. At last, we foresee its prospect.
