Hello,

I am working in NAD_1983_UTM_Zone_13N and have acquired data in NAD_1983_CSRS_UTM_Zone_13N. I was using the Project tool and the NAD_1983_CSRS_To_WGS_1984_2_ + WGS_1984_(ITRF00)_To_NAD_1983 transformation on my shapefile. Does this seem correct? I was just looking for clarification.

Thank you in advance.

Sincerely,
Sarina

Hello Sarina,

The transformation is putting together two transformations that try to account for the differences between NAD 1983 / NAD 1983 CSRS and WGS 1984. If you can acquire the NTv2 grid file, SK83-98.gsb, for Saskatchewan (I assume that's where the data is located), that will give you a direct transformation and should be more accurate. Here's some information:

Thank you Melita.

I just tried to contact Larry Cook at ISC and the email address on the link you provided is no longer valid. I will try to acquire the NAD_1983_To_NAD_1983_CSRS98_2  NAD_1983_To_WGS_1984_7 transformation from another contact at ISC.

Melita,

How do I copy this transformation into my pedata folder?

Thank you in advance.

Hi Sarina,

You just need to copy the gsb file to pedata\ntv2\canada in your ArcGIS installation folder. You will probably need to create the canada folder.
