Abstract:
The following is excerpted from the metadata provided by NOAA:

"This data contains a set of geodetic control stations maintained by the National Geodetic Survey. Each geodetic control station in this dataset has either a precise Latitude/Longitude used for horizontal control or a precise Orthometric Height used for vertical control, or both.

The National Geodetic Survey (NGS) serves as the Nation's depository for geodetic data. The NGS distributes geodetic data worldwide to a variety of users. These geodetic data include the final results of geodetic surveys, software programs to format, compute, verify, and adjust original survey observations or to convert values from one geodetic datum to another, and publications that describe how to obtain and use Geodetic Data products and services."

Purpose:
The following is excerpted from the metadata provided by NOAA:

"Provide a base of reference for latitude, longitude and height throughout the United States."

Attribute_Accuracy_Report:
The following is excerpted from the NOAA metadata:

"Horizontal control stations (those with precise Latitude, Longitude) were established in accordance with FGDC publications "Standards and Specifications for Geodetic Accuracy Standards" and "Geometric Geodetic Accuracy Standards and Specifications for Using GPS Relative Positioning Techniques." The final Latitude, Longitude of these stations were determined by a least squares adjustments of the horizontal observations. 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 attributes HD_HELD1, HD_HELD2, or SCALED. These lesser quality positions are described at:

< <http://www.ngs.noaa.gov/datasheets/> >

"Vertical 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 station have Latitude, Longitudes displayed to 2 or 3 places and are identified by attribute ELEV_SRCE of ADJUSTED, ADJ UNCH, POSTED,READJUST,N HEIGHT,RESET,COMPUTED

"Lesser quality Orthometric Heights may also be preset in the dataset. These are identified by a POS_SRCE attributes GPS_OBS, VERT_ANG, H_LEVEL, VERTCON, SCALED. These lesser quality orthometric heights are described at:

< <http://www.ngs.noaa.gov/datasheets/> >

"IMPORTANT - 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=SCALED> for a description of the various type of methods used in determining the Latitude, Longitude, and Orthometric Height.

"The attributes 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 attribure 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 more detailed explaination 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."

Process_Description:
The following is excerpted from the NOAA metadata:

"The National Geodetic Survey produces geodetic data. 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."

Shapefiles for each Indiana county were downloaded from the following URL of NOAA:

<http://www.ngs.noaa.gov/cgi-bin/datasheet.prl>

The shapefiles that were downloaded were those specified as "Any Horiz. and/or Vert. Control" and "Any stability." The shapefiles were then imported into ESRI ArcView 3.3 and merged together using the Geoprocessing Wizard. The resulting merged shapefile was then re-projected in ESRI ArcToolbox 9.0 from Geographic Coordinates to UTM Zone 16 NAD83 coordinates.

ELEV_CHECK - Y = Observational Check was made for the orthometric height, N = NO Observational Check was made for the orthometric heights

VERTCONED - Y=Orthometric Height was determined by applying VERTCON to an old NGVD 29 height. N = Orthometric Height determined by observations.

DIST_RATE- Distribution rate for POSTED and READJUSTED benchmarks which do not have an Order and Class are as follows "Posted bench marks" are vertical control points in the NGS data base which were excluded from the NAVD 88 general adjustment. Some of the bench marks were excluded due to large adjustment residuals, possibly caused by vertical movement of the bench marks during the time interval between different leveling epochs. Adjusted NAVD 88 are computed for posted bench marks by supplemental adjustments.

A range of mean distribution rate corrections is listed for each posted bench mark in the data portion of the publication. A summary table of the mean distribution rates and their codes is listed below. The mean distribution rate corrections which were applied to the original leveling observations is a good indication of the usefulness of the posted bench marks' adjusted NAVD 88 heights.

Distribution Rate Code Distribution Rate Correction

---------------------- ----------------------------

"a" 0.0 thru 1.0 mm/km

"b" 1.1 thru 2.0 "

"c" 2.1 thru 3.0 "

"d" 3.1 thru 4.0 "

"e" 4.1 thru 8.0 "

"f" greater than 8.0 mm/km

POSTED BENCH MARKS SHOULD BE USED WITH CAUTION. As is the case for all leveling projects, the manditory FGCS check leveling two-mark or three-mark tie procedure will usually detect any isolated movement (or other problem) at an individual bench mark. Of course, regional movement affecting all the marks equally is not detected by the two- or three-mark tie procedure.

ELLP_ORDER - Order of accuracy for the ELLIP_HT Should be 1,2,3,4, or 5 if present. The following ellipsoid height order and class relative accuracy standards have not yet been adopted by the Federal Geodetic Control Subcommittee, but are currently in use by NGS-

Ellipsoid Height Classification Maximum Height Difference Accuracy

------------------------------- -----------------------------------

1 class 1 0.5 (mm)/sqrt(km)

1 class 2 0.7

2 class 1 1.0

2 class 2 1.3

3 class 1 2.0

3 class 2 3.0

4 class 1 6.0

4 class 2 15.0

5 class 1 30.0

5 class 2 60.0

The ellipsoid height difference accuracy (b) is computed from a a minimally constrained correctly weighted least squares adjustment by the following formula [ b = s / sqrt(d) ]. Where "b" = height difference accuracy, "s" = propagated standard deviation of ellipsoid height difference in millimeters between control points obtained from the least squares adjustment, and "d" = horizontal distance between control points in kilometers

ELLP_class - Class of accuracy for ELLIP_HT Should be 1 or 2 See details under ELLP_ORDER

1_RECV - Date when the station was first monumented or in the case of landmarks, first observed.

LAST_RECV - Date when the station was last recovered.
