Site Identification of the GPS Monument Site Name : Easter Island Laser Station Four Character ID : EISL Monument Inscription : JPL 4008-S IERS DOMES Number : 41703M003 CDP Number : None Date Installed : 1992 hh:mm UT Geologic Characteristic : (BEDROCK/CLAY/CONGLOMERATE/GRAVEL/SAND/etc) Bedrock Type : (IGNEOUS/METAMORPHIC/SEDIMENTARY) Bedrock Condition : (FRESH/JOINTED/WEATHERED) Fracture Spacing : (1-10 cm/10-50 cm/50-200 cm/over 200 cm) Notes : (multiple lines) Additional Information : East South Pacific Island, about 500 kilometers : east of the crest of the East Pacific Rise. : The island is the product of three principle : volcanic structures. : Some evidence suggests that the island is on a : microplate at the edge of the Nazca Plate. : Geological information from "NASA Space Geodesy : Program: Catalogue of Site Information", : Technical Memorandum 4482, March 1993, p99. 2. Site Location Information City or Town : Easter Island State or Province : Country : Chile Tectonic Plate : Pacific/Nazca Approximate Position X coordinate (m) : -1884951.8173 Y coordinate (m) : -5357595.8630 Z coordinate (m) : -2892890.5180 Latitude (deg) : -27.14820869 Longitude (deg) : -109.38329771 Elevation (m) : 114.5179 Additional Information : Latitude, Longitude and Elevation derived from : "IERS Technical Note 20, Results and Analysis : of the ITRF94" March 1996; Table 6 "ITRF94 : Class B Station Coordinates at Epoch 1993.0", : pT68. : The site is located on the southwest part of the : South Pacific Chilean island, Easter Island. The : facility is located inland about 2.5 miles : northeast of Mataveri Airport. : To reach the station from the main entrance to : the Mataveri Airport, proceed southeast along a : dirt road that parallels the runway for 1.2 : kilometers to a fork in the road. Bear left : (northeast) onto the left fork and proceed 4.1 : kilometers to the entrance road to the NASA site : on the left (north). This mark was established : for permanent GPS observations. The stainless : steel plate is set flush in the center of a : 0.610 meter diameter concrete monolith that : projects 0.5 meters above the ground. : Site information from "NASA Space Geodesy : Program: Catalogue of Site Information", : Technical Memorandum 4482, March 1993, p99 and : 102a. 3.
