EPSG:4269 - NAD83

Selected transformation

Method: NTv2

Grid Files: NTv2_0.gsb

Remarks: Uses NTv2 data files. Replaces NTv1 (transformation code 1312) except in Quebec. Input expects longitudes to be positive west; EPSG GeogCRS NAD27 (code 4267) and (code 4269) have longitudes positive east. May be used as tfm to WGS 84 - see code 1693.
