Abstract:
In 1991, Dodge County was part of a three county consortium effort to regionally densify the Wisconsin HARN (High Accuracy Reference Network). The project was done in cooperation with the Wisconsin Dept. of Transportation and Rock and Jefferson Counties. Following the "Request for Proposal (RFP) on the Establishment of a High Precision Geodetic Network Using Global Positioning System (GPS) Technology for Dodge, Jefferson, and Rock Counties, Wisconsin" (November 11, 1992), Dodge County developed a locally densified geodetic network at the primary (5-1ppm stations), secondary (14-2ppm stations), and tertiary (57-4ppm stations) levels. THE RESULTING POSITIONS COMPRISE THE DATA DOCUMENTED HERE.

Purpose:
Dodge County GPS Net geodetic positions are intended to be used as the primary spatial reference system for surveying and mapping activities in Dodge County.

Data_Quality_Information:

Logical_Consistency_Report:
These data have been reviewed by the Wisconsin Department of Transportation for the validity of values and relationships between geodetic stations and their reported positions.

Completeness_Report:
This data set has been reviewed to assure that it contains all the stations comprising the Dodge County GPS Net.

Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal accuracy of these digital data ranges from 1-4 ppm and is based upon their relationship to the National Spatial Reference System, and in particular, the NSRS stations that comprise the Wisconsin High Accuracy Reference Network (HARN) - an independent source of higher accuracy.

These geodetic positions were produced using the survey standards and specifications contained in "Request for Proposal (RFP) on the Establishment of a High Precision Geodetic Network Using Global Positioning System (GPS) Technology for Dodge, Jefferson, and Rock Counties, Wisconsin" (November 11, 1992), an enhancement of the Federal Geodetic Control Subcommittee's "Geometric Geodetic Accuracy Standards and Specifications for Using GPS Relative Positioning Techniques" (draft, May 11, 1988).

Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The vertical accuracy of these data (ellipsoid height) ranges from 2 to 3 centimeters and was tested by comparison to the Wisconsin HARN - an independent source of higher accuracy.

The project RFP contains the geodetic network design and GPS survey standards and specifications used to complete both field and office work.

Process_Step:
Process_Description:
Western Geophysical, under contract to Wisconsin DOT, obtained the GPS survey observation, processed the data, and performed a least squares adjustment of the stations which would comprise the Wisconsin HARN.
Process_Date: 1991

Process_Step:
Process_Description:
The National Geodetic Survey reprocessed the raw data obtained by Western Geophysical, readjusted it, and published those results. Those NGS published positions are the ones accepted and used for work involving the Wisconsin HARN.
Process_Date: 1991

Process_Step:
Process_Description:
Aerometric Engineering Inc., under contract to Dodge County performed additional GPS survey observations in Dodge, Rock and Jefferson counties, using stations of the Wisconsin HARN as base points. The field data was processed and adjusted in accordance with the project RFP. The Dodge county portion of the densified and adjusted network forms the Dodge County GPS Net.
