||I have received a file of geographic (lat/long) coordinates that I need to convert to UTM Zone 10 NAD83. The locations are in British Columbia, Canada. The data are in horizontal datum NAD83-CSRS.
When reprojecting the data in ArcToolbox, there is no datum transformation method listed that is applicable to NAD83-CSRS in BC. As far as I can tell, the CSRS methods listed are for other parts of Canada.
What is the appropriate datum transformation method to use?
I'm using ArcGIS 9.0 -- we have the more recent upgrades but haven't installed them yet. Is the BC NAD83-CSRS datum transformation method available in more recent versions of ArcGIS?
What degree of error would be introduced by treating the input data as regular NAD83 instead?
