Submit a PLSS or Control Dataset to the SCO

How to add your data

Adding data to Survey Control Finder is easy: simply provide, at minimum:

  • Point ID
  • Point Type
  • Coordinates & Date
  • Coordinate Class/Accuracy
  • Orthometric Heights (if available)
  • Other attributes from Data Dictionary below (if possible)

Email your dataset, preferred formats are GeoDatabase or an ArcGIS shapefile (.shp), to Brenda Hemstead at hemstead@wisc.edu or call with questions at 608/263-4371

Data Dictionary

Point ID: unique point ID

Category: type of dataset (PLSS, Geodetic Control, etc.)

Point Type: section corner, meander, water tower, benchmark etc.

Monument Type & Date: the material or composition (alum cap or marker) and date/year the monument was set/reset

Coordinates & Date:

  • Easting & Northing Coordinates: county coordinates or state plane coordinates along with the reference datum.
  • Geographic Longitude & Latitude Coordinates: latitudes are referenced as positive north and negative south; longitudes are referenced as positive east and negative west along with the reference datum
  • Coordinate System: WCCS, WISCRS, SPC, etc.
  • Date: mm/dd/yyyy (if available) of the coordinates

Coordinate Class/Accuracy: accuracy or reliability for the horizontal coordinate position, i.e., survey grade, sub-meter, approximate, etc.

  • Survey Grade: Coordinates collected under the direction of a Professional Land Surveyor, in a coordinate system allowed by 236.18(2), and obtained by means, methods and equipment capable of repeatable 2 centimeter or better precision
  • Sub-meter: point precision of 1 meter or better
  • Approximate: point precision within 5 meters or coordinates derived from public records or other relevant information

Orthometric Height: refers to the distance measured along the plumb line between the geoid and a point on the Earth’s surface, taken positive upward from the geoid. Include the datum (NAVD 88 or NGVD 27) and units (feet/meters).

Section/Township/Range: i.e., T25N or T3S, R5W or R15E, Section 1-36

URL: full URL path to link each record to link to their tie/data sheet

Comments: any additional information about the point, such as condition, monument type, etc.

Online Tie Sheets: full URL path to link to each record’s corresponding tie/data sheet

URL2: additional URLs to link to other related information

Dataset Metadata: URL to the metadata file

Contacts: contact information for the dataset
