Horizontal control station have Latitude, Longitudes displayed to 5 places and are identified by attribute POS_SRCE = 'ADJUSTED'Lesser quality Latitude, Longitudes may also be preset in the dataset.These are identified by a POS_SRCE attributesHD_HELD1, HD_HELD2, or SCALED.These lesser quality positions are described at:http://www.ngs.noaa.gov/cgi-bin/ds_lookup.prl?Item=SCALEDVertical control stations (those with precise Orthometric Heights) were established in accordance with FGDC publications \"Standards and Specifications for Geodetic Accuracy Standards\" The final Orthometric Height of these stations were in most cases determined by a least squares adjustments of the vertical observations but in some cases may have been keyed from old survey documents. Vertical control stations have Orthometric Heights displayed to 2 or 3 places and are identified by attribute ELEV_SRCE of ADJUSTED, ADJ UNCH, POSTED,READJUST,N HEIGHT,RESET,COMPUTEDLesser quality Orthometric Heights may also be preset in the dataset.These are identified by a ELEV_SRCE attributesGPS_OBS, VERT_ANG, H_LEVEL, VERTCON, SCALED.These lesser quality orthometric heights are described at:http://www.ngs.noaa.gov/cgi-bin/ds_lookup.prl?Item=SCALEDIMPORTANT - Control stations do not always have both precise Latitude, Longitude AND precise Orthometric Height. A horizontal control station may have a orthometric height associated with it which is of non geodetic quality. These types of heights are displayed to 0, 1, or 2 decimal places. Worst case being off by +/- 1 meter. LIKEWISE - A Vertical control station may have a Latitude, Longitude associated with it which is of non geodetic quality. These types of Latitude, Longitudes are displayed to 0, 1 or 2 decimal places. Worst case being off by +/- 180 meter. Refer to http://www.ngs.noaa.gov/cgi-bin/ds_lookup.prl?Item=SCALEDfor a description of the various type of methods used in determiningthe Latitude, Longitude, and Orthometric Height.Attribute POS_CHECK and ELEV_CHECK indicate whether or not an observational check was made to the position and/or orthometric height. Care should be taken when using \"No Check\" coordinates.If attribute ELEV_SRCE = 'VERTCON' then the Orthometric Height was determined by applying NGS program VERTCON to an Old NGVD 29 height. In most areas VERTCON gives results to +/- 2 cm. See http://www.ngs.noaa.gov/TOOLS/Vertcon/vertcon.html for a moredetailed explanation of VERTCON accuracy.Ellipsoid Heights are also present in the dataset. The ellipsoid heights consist of those determined using a precise geoid model, which are displayed to 2 decimal places and are considered good to +/- .005 meters, and those displayed to 1 decimal place and are considered only good to +/- .5 meters | Quantitative Value: 95 percent confidence level for geodetic quality data. | Quantitative Test Explanation: Geodetic Data are continuously being processed; their standards and specifications are being reviewed for next publication release. \"Standards and Specifications for Geodetic Control Networks\", 1984 and \"Geometric Geodetic Accuracy Standards and Specifications for Using GPS Relative Positioning Techniques,\" FGCS (formally FGCC) publication version 5.0 1989, are most current published documents.\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Horizontal Positional Accuracy\r\n \r\n \r\n The description of tests are explained in \"Geometric Geodetic Accuracy Standards and Specifications For Using GPS Relative Positioning Techniques,\" FGCS (formally FGCC) publication version 5.0, 1989.; Quantitative Value: .05 meters, Test that produced the value: Horizontal positional accuracy statements pertain to horizontal control stations only. i.e. Those with geodetic quality Latitude, Longitudes.

Geodetic data comprise the results of geodetic surveys to determine, among other things, latitude, longitude, height, scale, and orientation control. The National Geodetic Survey original field survey project observations and final reports are accessioned into records system of the National Archives and Records Administration of the U.S.A. These surveys provide information valuable for a variety of uses in the mapping, charting and surveying community.The NGS' final product is the geodetic data sheet. Geodetic data sheets are comprehensive summaries of all published information for a given geodetic reference point, including: the geographic position and/or height based on the current reference datum, condition of the survey mark when it was last visited, a description of where the point is located and how to reach it, and an explanation of the terms used in the data sheet. In support of these geodetic data, the NGS provides software, publications, and various user services, including geodetic advisor program, instrument calibration, surveying standards, and technical workshops.This dataset contains certain information extracted from the above mentioned data sheet.\r\n \r\n \r\n \r\n \r\n \r\n \r\n Source Contribution: The geodetic data must be submitted in the digital formats specified in the FGCS (formally FGCC) publication \"Input Formats and Specifications of the National Geodetic Survey Data Base\" which describes the formats and procedures for submission of data for adjustment and assimilation into the National Geodetic Survey Data Base.
