The following metadata was downloaded from http://www.nysgis.state.ny.us/gis3/data/dot.nysvydb.html. The data was downloaded (password required) and projected to NAD83 in ArcInfo. The survey point locations within the 10-mile Adirondack Park buffer were selected and converted to a shapefile in ArcView. Two new fields were added to the data table UTM_83_NOR and UTM_83_EAS giving the UTM coordinates of the survey markers in NAD83.

Description:
Abstract:
Point coverage of the entire survey monument database of New York State, extracted from the National Geodetic Survey (NGS) CD-ROM Edition 1997. Approximately 20,000 points are in the database, including the 218 points that comprise the New York State Geodetic HARN Network.
Purpose:
File is suitable for use in locating survey control points for a project. Certain information for each point in the file can be used to extract a complete data sheet description file from the NGS website.

Completeness_Report:
Coverage includes geodetic points from the Survey Monument Database for New York State. Point features are attributed with: point designation; pid; latitude; longitude; horizontal order; horizontal datum; orthometric height; vertical order; vertical datum; position source; county; state; USGS Quadrangle; UTM NAD27 Easting; UTM NAD27 Northing. New York State Department (NYSDOT) Geodetic HARN Network is included (designated as points with a horizontal order of A or B).

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The accuracy of each control point is a function of the position source field. All points with a horizontal accuracy are true to that accuracy minus the datum transformation error (0.1 - 0.3) to NAD 27 using NADCON, in addition to the error from rounding to the nearest meter.

Process_Description:
The National Geodetic Survey CD-ROM 1997 Edition, in the NAD 83 coordinate system served as the original source for the file. NGS extraction software was used to extract geodetic points and their attributes. The latitude/longitude coordinates were converted to UTM zone 18 NAD 27 using NADCON. The Easting and Northing coordinates were truncated, and then rounded to the nearest meter. These coordinates were used to create an event theme in ARC/VIEW. Point features were attributed with fields selected from the National Geodetic Survey CD-ROM 1997 Edition.
