Seismotectonic maps in the vicinity of the lower Wabash Valley, Illinois, Indiana, and Kentucky - Digital Spatial Database: Global Positioning System stations

This cover contains the location of global positioning system
stations that are located within the project boundary. Several GPS
networks with various monument spacings are being used to monitor
deformation in parts or all of the Mississippi embayment. One network
is regional, and two of the network stations are located in western
Kentucky within our map area.

本数据集包含位于项目边界内的全球定位系统（Global Positioning System，GPS）台站的位置信息。本研究采用多组标石间距各异的GPS监测网，对密西西比河凹陷区的部分或全部区域开展形变监测。其中一组为区域级监测网，该网内的两台站位于本研究制图覆盖范围内的肯塔基州西部。
