Muted locks

The dataset shows the location of muted locks and districts that are not included in the location table (globis locations). In 2004, a map and aerial photo study was carried out, in which all attenuations with the help of aerial photographs and topographic maps were obsolete. In many attenuations, the damping material was unknown. A follow-up study in 2007 has tried to find out what these so-called unspecified dampings are filled with. The dampings at which this was successful are included in the location file of Globis (bottom information system).本数据集收录了静音锁具（muted locks）的位置，以及未纳入Globis位置表（globis locations）的区域的位置。2004年，研究团队开展了一项结合地图与航空照片的调研，本次调研中，所有借助航空照片与地形图识别得到的阻尼装置（attenuations）均已失效。多数阻尼装置的所用阻尼材料均未明确。2007年开展的后续研究旨在探明这些所谓未明确阻尼装置的内部填充介质。成功完成该项探查的阻尼装置已被收录至Globis（底层信息系统）的位置文件中。
