EPSG:8826

NAD83 / Idaho Transverse Mercator

Available transformations
to EPSG:4152

Selected transformation

Method: NADCON

Grid Files: wmhpgn.las wmhpgn.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 1716.
