3S技术在遗址探查中的应用

常规遗址探查方法,普查难度大,影像上不能直接识别小型遗址.为此,应用3S技术(遥感技术(RS)、全球定位系统(GPS)、地理信息系统(GIS))在遗址探查中的作用和优势,提出了基于地物空间关系知识、多源信息复合探查的思路.应用结果以巢湖柘皋区为例,将该区遥感图像中提取的古河道信息层和数字化后的地形图上标注为独立物(其中包括已知、疑似遗址点)层叠合,在地理信息系统中总结已知遗址点的分布规律,筛选出疑似遗址点,并将其GPS定位信息与近期巢湖文物管理部门野外实测记录对比,提取的疑似遗址点中包含了普查记录的遗址.3s技术的应用表明,该方法可为考古普查工作节省大量时间、人力和物力.

The application of 3S technology in the exploration of site

This paper mainly discusses the effect,conventional method and advantage of 3S technology applied in exploration of sites.Because of the difficulty of general investigation,especially,some unidentified small sites in the imagery,the idea of multi resource geo information exploration composite,based on the knowledge of landmark spatial relationship,was put forward.Take Zhe Gao area in Chao Hu as an Example,old Channel information layer and digitized topographic map extracting from remote sensing image in this area is indicated independent of object (including known and suspected sites) layer laminated,according to distribution law in geo graphical information system of summarized known sites and screened out suspected sites.In the end,compare the information of GPS with recent field measured data of Chao Hu cultural relics management department,it was found that extracted suspected sites contained mass screening recorded sites,and also had obtained the best result.
