EPSG:26773

NAD27 / Indiana East

Available transformations
to EPSG:4326

Selected transformation

Name: NAD27 to WGS 84 (79)

Method: NADCON

Grid Files: conus.las conus.los

Remarks: Parameter files are from NAD27 to NAD83 (1) (code 1241) assuming that NAD83 is equivalent to WGS 84 within the accuracy of this tfm. Uses NADCON method which expects longitudes positive west; EPSG CRS codes 4267 and 4326 have longitudes positive east.
