Slide7objectives
Horizontal Datum Horizontal accuracies to comply with California Public Resources Code 8856 having a positional accuracy of two centimeters or better.GPS static measurements to the California Continuous Operating Reference Stations (CORS). Geodetic coordinates for CORS stations USLO, P516, and P513 used as the basis for this survey.Benchmarks and GIS mapping referenced to the California Coordinate System 1983, CCS83, (epoch 2011), Zone 5.
Slide8objectives
Vertical Datum Vertical accuracies to comply with California Public Resources Code 8858 having a positional accuracy of five centimeters or better. Benchmark "Beach 1974“ elevation held for this survey, having a published elevation of 122.42' feet.Benchmarks and GIS mapping referenced to the North American Vertical Datum of 1988 (NAVD88) through ties to established local benchmarks within the City of Pismo Beach.GIS Data
GIS Layer containing the newly established benchmark locations incorporated into a geodatabase
along with attributes with spatial links to field notes and digital imagery for each point.
Slide9Techniques and Equipment used
Primary ControlPrimary benchmarks observed for 30 minutes and post-processed using Trimble Business Center software version 2.5 along with CORS stations USLO, P516, and P513 . Least Squares adjustment processed using Trimble Business Center software version 2.5 Residuals printed and included in the surveyor's report.
