Point feature class and related table containing the Precise Surveys measurement time series. Measurements include elevations, Northings and Eastings, distances, and point-to-point measurements. Northing and Easting measurements are in CA State Plane Coordinate systems, Elevations measurements are provided in NAVD88 or NGVD29. This dataset is for data exploration only. These measurements and point locations are not considered survey-grade since there may be nuances such as epochs, adjustments, and measurement methods that are not fully reflected in the GIS data. These values are not considered authoritative values and should not be used in-lieu of actual surveyed values provided by a licensed land surveyor. Please contact Richard Carter at Richard.Carter@water.ca.gov if you need the official measurements, adjustments, and epoch information. Data is a point feature class presenting the mark locations, mark names, and appropriate data about the mark used for the survey measurement. Related data and time series are stored in a table connected to the point feature class via a relationship class. There may be multiple table entries and time series associated to a single mark. Data was assembled through an import of Excel tables and import of mark locations in ArcGIS Pro. Records were edited by DOE, Geomatics, GDSS to resolve any non-unique mark names. This dataset was last updated 4/2024.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "summary": "Survey data as part of the 'Precise Surveys' project has been collected from points along the State Water Project.
