Site Identification of the GNSS Monument Site Name : WUHAN Four Character ID : WUHN Monument Inscription : I.G.S. Reference Station IERS DOMES Number : 21602M001 CDP Number : Monument Description : PILLAR Height of the Monument : 2.46 m Monument Foundation : GRANITE BLOCK Foundation Depth : 2.99 m Marker Description : CHISELLED BRASS NAIL Date Installed : 1993-01-08T00:00Z Geologic Characteristic : GRAVEL Bedrock Type : SEDIMENTARY Bedrock Condition : FRESH Fracture Spacing : 1-10 cm Fault zones nearby : NO Distance/activity : Additional Information : The monument is a solid granite pillar ~5.5m in length it sits on a buried brick rampart built in 1957. 3m are buried and 2 meters are exposed. The surface extension of the pillar consists of a series of steps starting with a width of 1.24x1.24m and stepping through 0.72x0.72m, 0.70x0.70m, 0.56x0.56m, 0.50x0.50m, 0.455x0.455m. The antenna is attached to the top of the pillar. The entire pillar is enclosed inside a building with a dome that functions as part of the roof of the building (see photos). 2.
