Horizontal Datum

HORIZONTAL DATUM: CCS 83', CA, ZONE 5, EPOCH 2017.50, PER G25-002 The coordinates shown hereon were derived from Real Time Kinematic (RTK) surveying using two independent observations tied to four independent California Real Time Network (CRTN) stations with baselines limited to 20km. Under optimal conditions, with a clear line of sight to the sky and minimal interference, RTK surveying tied to the CRTN network can provide horizontal accuracy of up to 1 cm + 1 ppm (parts per million) and vertical accuracy of up to 2 cm + 1 ppm. These values reflect the precision achievable in real-time with differential corrections broadcasted by the network. The purpose of this survey is for Geographic Information Systems and Asset Inventory purposes and the relative horizontal accuracy of the coordinates shown hereon is such that it complies with the accuracy classifications for Geographic Information Systems (GIS) and Asset Inventory as shown in the table for Network Applications in the Joint Publication of the California Land Surveyors Association and California Spatial Reference Center GNSS Surveying Standards and Specifications Version 1.1 dated December 10, 2014.
