I am trying to change my WGS84 data to NAD83 for Alberta data. My research tells me that I need to use the NAD_1983_TO_WGS_1984_8 Datum Transformation which is in the AB_CSRS.gsb. I can not find this gsb file for download on the internet. I did manage to find and obtain the NTv2_0.GSB but that seems to only be for NAD27 To NAD83.
Does anyone know where I can get the AB_CSRS.GSB file?
