土地利用现状数据缩编方法探讨

Study on method of current land use map generalizing

在国家第二次土地调查数据通过核查后,要求各省在此基础上开展多比例尺的数据缩编工作以利于成果的各类应用。本文就如何开展土地利用现状数据缩编工作进行了探讨,重点介绍了数据缩编工作的技术路线,对各类空间要素的缩编处理进行详细阐述。通过对典型区进行缩编实践,最终得到了满足国家技术指标要求、符合地方实际的数据。

The work of map generalization of multi-scale maps is required to be conductive to the application of the result data of the Second National Land Surveying. The paper discussed some questions about map generalization, put forward technology route of this work, and introduced data processing step especially. Through experiment on typical area, it put out the result map, which according to national technology requirement, also adapted to the current situation of native land use.
