摘要
以福建省森林资源基础地理数据为研究对象,论述了数据改造的过程及其关键技术。通过解析福建省森林资源基础地理数据的现状,分析了数据误差来源,探讨数据标准化、数据整改、误差处理、矢量精度修正、格式统一及转换等过程的关键技术。研究表明,改造后的福建省森林资源基础地理数据的质量得到了提高,满足了全省森林资源管理的需要。
Based on the studying of forest resources foundation geographical data in Fujian Province, the process of data transformation and key technologies were elaborated in the paper. Through analyzing the current status of forest resources foundation geographical data in Fujian Province, the data error sources was analyzed, and key technologies, such as the data standardization, the data reorganization, the error correction, the vector precision rectification, the process of date format unification and transformation, were discussed. The study indicated that after the quality of transformation forest resource foundation geographical data in Fujian Province quality had been improved to meet the needs of the forest resources management in Fujian Province.
