    摘要:

    [目的] 开展基于高分遥感的生产建设项目提取技术的研究,全面、及时地掌握生产建设项目分布信息,满足水土保持监管的迫切需求。[方法] 以陕西省榆林市的部分区域为研究区,利用2013和2014年两个时相的GF-1影像,通过面向对象的直接比较法,提取变化信息,并结合光谱、形状等特征,去除伪变化,获取区域范围内新增的裸地和不透水面。另外,结合专家知识,提取疑似施工期生产建设项目信息。[结果] 新增裸地和不透水面的发现精度达到83.53%, 疑似施工期生产建设项目的发现精度为95.56%。[结论] 该方法能够有效地提取施工期生产建设项目分布信息。

    Abstract:

    [Objective] To study the technologies on the extraction of information on the production and construction projects based on the high resolution remote sensing data in order to provide a quick way to timely capture the overall information on the distribution of production and construction projects, and to monitor soil and water conservation.[Methods] Taking some areas in Yulin City of Shaanxi Province as the study area, using GF-1 images acquired in 2013 and 2014, we used the object-oriented direct comparison method to extract the change information. Then combined with spectrum analysis and shape characteristics, pseudo changes were removed, and new bare land and impervious surface were acquired. In addition, with the help of expert knowledge, the distribution information of possible production and construction projects in the construction period was obtained.[Results] The accuracy of new bare land and impervious surface reached 83.53%, and the accuracy of possible production and construction projects in the construction period reached 95.56%.[Conclusion] This method can effectively extract the distribution information on production and construction projects in the construction period.
