NAD 83 should be EPSG:4269, not EPSG:4629
Created by: das-g
EPSG:4629 (Tahaa 54) (SR-ORG) is for French Polynesia, while EPSG:4269 (NAD 1983) (SR-ORG) is for the whole of North America (and AFAIK usable globally, even).
We currently have them mixed up and transform to EPSG:4629 when 'NAD 83' is selected.
