Dear all,

I have a excel file with xy coordinates for points in the ITRF 2005 format. I am trying to convert the xy coordinates to xy coordinates in the  WGS 84 format. Any ideas how i can go about this or the conversion. Please take a look at the attached excel table of my ITRF 2005 xy Coordinates that i need to convert to xy WGS 84 values.

Hi Ali,

I'm taking a look at your data, and the points are projected (looks like UTM, but they're definitely not Lat/Long).  Do you know the original projection in order to reproject them to WGS84?

Other than that, the step by step is:

1) Set dataframe projection to match your source data (Projection/ITRF2005 datum)

2) Add your XY data to the map

3) Export as a new feature class or shapefile

4) Run 'Project (Data Management)' tool to project your shapefile/feature class to your new projection and save it.

5) Create new XY fields containing the new coordinates of your new projected feature class/shapefile

6) If you require it, export them to a new excel table.

Dear Todd,

Thank you for the response. I followed what you outlined earlier but i keep getting an error when i try Project the ITRF 2005 Point feature class to WSG84 UTM Zone 35S using the data management Project tool. It gives an error with feature class empty.

Thank you Todd and Melita i finally got it projected in WGS84.

Your original points are in UTM coordinates or possibly Gauss-Kruger. We don't have any geographic/datum transformations between ITRF and WGS 1984 because WGS 1984 is kept more or less coincident with ITRF. So, I would follow the steps 1-3 Todd Blanchette​  but immediately set the coordinate system of the XY data in ArcMap to WGS 1984 whatever-zone-the-data-is-in. If you need WGS 1984 decimal degree values, you can then continue with steps 4-6.
