I want to reproject a few raster datasets from GCS_WGS_1984 to NAD_1983. The data is for the province of British Columbia in Canada. Could someone help me choose the correct transformation? My options range for NAD_1983_To_WGS_1984_(1 through 8). There is no mention of British Columbia in this ESRI document (http://resources.arcgis.com/content/kbase?fa=articleShow&d=24159) describing each of these transformations.
