资源一号02C卫星数据在地质公园调查中的应用 ——以天津市蓟县为例

Application of ZY1-02 C remote sensing data to the investigation of geoparks：Taking Jixian County,Tianjin City for example

随着地质旅游资源开发的不断深入,建立了大量的地质公园,迫切要求对地质公园内的地质遗迹进行全面、系统的调查,查明地质遗迹的数量、性质和特点等.利用遥感技术可以全面了解区域地质遗迹分布,探索和拓展新的地质遗迹,还可以监测和保护已有的地质遗迹,国产卫星的陆续发射升空为开展地质遗迹遥感调查提供了很大便利.以天津市蓟县国家地质公园为例,探讨了资源一号02C卫星在地质公园调查中的应用,首先利用影像建立了中新元古界地层解译标志,并结合高分二号卫星影像对典型地质建造进行了提取和分析,最后生成了盘山花岗岩地貌景区三维影像,为地质公园参观路线提供了直接资料.研究结果表明,资源一号02C卫星数据具有清晰的纹理结构,对地层单元的细分具有一定优势;高分二号影像结合DEM生成的三维遥感可视化场景对于地质公园参观路线的优选具有实际应用参考价值.

With the further development of geological tourist resources, a large number of geoparks are established, which urgently needs the comprehensive and systematic investigation of the geo-heritage, finding out the quantity, quality and traits. With remote sensing technology, the distribution of the regional geo -heritage can be fully understood, new geo-heritage can be explored and expanded and the existing geo-heritage can be monitored and protected. The successive launch of the domestic satellites provides great convenience for the remote sensing investigation of geo - heritage. This paper takes Jixian National Geopark as an example, probing into the application of ZY1-02C satellite to the investigation of geo-heritage. The interpreting marks of middle-upper Proterozoic strata are created by using images, and combined with GF -2 satellite image, the typical geological formation is derived and analyzed, finally generating the 3D image of Panshan granitic geomorphologic landscape, which forms the direct material for the visiting route in the geopark. The result indicates that the data of ZY1-02C satellite has clear texture, better for the subdivision of stratigraphic unit; the 3D remote sensing visual scene produced by the combination of GF -2 satellite image and DEM is worth the reference for the selection of the visiting route in the geopark.
