We are attempting to reproject several raster and vector datasets from GCS_GRS_1980 to WGS_1984_Web_Mercator_Auxiliary_Sphere. I have tried a several different transformations but each time there is a noticeable shift in the data. Does anyone know the correct transformation to use? Our data is mostly in the SE United States, mainly Georgia, South Carolina, & North Carolina. We also have a few datasets that span the entire USA.
I'm having the same problem determining the correct transformation from state plane (GA FT, SC Int FT, & NC FT) to web mercator. Any ideas?
Thank you very much in advance!
