EPSG:3161

NAD83 / Ontario MNR Lambert

Available transformations
to EPSG:4152

Selected transformation

Method: NADCON

Grid Files: tnhpgn.las tnhpgn.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 1733.
