EPSG:3739

NAD83 / Wyoming West (ftUS)

Available transformations
to EPSG:4152

Selected transformation

Method: NADCON

Grid Files: cohpgn.las cohpgn.los

Remarks: Accuracy 67% confidence level. Uses NADCON method which expects longitudes positive west; EPSG GeogCRSs NAD83 (code 4269) and NAD83(HARN) (code 4152) have longitudes positive east. May be taken as approximate transformation NAD83-WGS 84 - see code 1712.

Attributes

Unit: US survey foot

Geodetic CRS: NAD83

Datum: North American Datum 1983

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG
