基于土地利用数据库重建的技术思路

Thought on Land Use Database Reconstruction Technology

以SPOT5卫星数据为信息采集源,利用GIS与遥感相结合的方法对黑龙江省某县原有的土地利用数据库进行更新。着重阐述了进行更新的方法步骤。在更新过程中,卫星数据和原有土地利用数据库两种数据能够充分发挥各自的优势,做到相互补充和印证。

Taking the SPOT5 satellite data as the information collecting source,combining GIS with remote sensing method,the original land use database updated for a county in Heilongjiang Province.The paper focuses on the introduction of the updating method and steps,and the two kinds of data,namely the satellite data and reconstruction land use data,can play their respective advantages and complementary role during the updating.
