GPS POSITION REQUIREMENTS



A coordinate reading from a GPS unit is required for all traffic counts (including manual traffic counts) at the count location. Coordinates are to be recorded as Latitude/Longitude or UTM (Universal Transverse Mercator). Coordinates will be confirmed by the main office.

For UTM, GPS units must have the following settings:

• Datum: NAD 1983 (NAD = North American Datum)

• Units: meters

For Latitude/Longitude, GPS units must have the following settings:

• Datum: WGS 1984 (WGS = World Geodetic System)

• Units: decimal degrees

If unable to record coordinates, leave the UTM columns and the Latitude/Longitude columns blank. Enter a note in the Comments column explaining why coordinates could not be recorded.

The coordinates must be saved in an EXCEL (.xls) spreadsheet. The naming convention of the EXCEL file must be in accordance with the following rules:

GPS-R[region number]WW[work week number].XLS

The filename for the example below is GPS-R11WW43.xls.

The EXCEL template file is downloadable at the following address:
