I am using ArcMap 10.7.
It comes down to needing to get my data into a local custom spatial reference system. I have not yet been able to project my data into it.
Desired coordinate system/spatial reference: Calgary_3TM_WGS_1984_W114
Projection: Transverse_Mercator false_easting: 0.0 false_northing: 0.0 central_meridian: -114.0 scale_factor: 0.9999 latitude_of_origin: 0.0 Linear Unit: Meter (1.0) Geographic Coordinate System: GCS_WGS_1984 Angular Unit: Degree (0.0174532925199433) Prime Meridian: Greenwich (0.0) Datum: D_WGS_1984 Spheroid: World_Geodetic_System_of_1984_GEM_10C Semimajor Axis: 6378137.0 Semiminor Axis: 6356752.314245179 Inverse Flattening: 298.257223563
So far I have tried a number of the datum transformations included in ArcGIS for NAD83 -> WGS84 but none have worked, resulting in errors such as 'geographic transformation not valid'.
To create a new custom geographic transformation I was never taught, and looking online has extremely little information on doing so, and the printed material simply explains what geographic transformations are and no further. I have so far only found a single video, which brings up the issue of the 'method' of the transformation. I haven't been able to find anything from Esri on the subject (but perhaps I am not looking in the right place).
What am I doing incorrectly, or what must I do in moving forward on this?
