Using ArcMap, i created a 'Feature Dataset (FD)' and set it to WGS84, F23s.

If i export a shapefile in SAD69 F23s, to this FD, it automatically project the shapefile to WGS, using the "SAD_1969_To_WGS_1984_14" transformation (WKID 1877).

I want to make the same operation, but instead of using this transformation, using the "SAD_1969_To_WGS_1984_13" (WKID 1876).

Is it possible?

    Can you explain "the way i need", and what transformation is used instead? What software are you using? – AndreJ Jul 27 '16 at 18:31
  • I edited my post, so i think its better explained. – raphael Jul 27 '16 at 19:52

    Those two transforms cover two distinct areas. Is your data in Brazil or Venezuela? – Mintx Jul 27 '16 at 20:07
  • My entire data is in Brazil. But for some determinations of the company who hired us, we must use the 14. – raphael Jul 27 '16 at 20:24

A transformation is used when projecting features from one Coordinate System to another. A Feature Dataset does not store the transformation, but rather the features are stored in the Coordinate System they have been saved in. The transformation happens at projection.

You will need to project your features first, selecting the desired transformation when projecting.

See Project - ArcGIS Desktop Help

Once they have been projected you can then load them into the Feature Dataset.

  • But i did some tests, and the system apply a transformation, just simply exporting the shapefile to a Feature Dataset. So, it does the project with some transformation. I just want to set up exactly which one, i want to use. – raphael Jul 27 '16 at 18:39

    +1 If you need to store the geotransformation used for each feature, I suppose you could add an field and populate it with the Wkid of the geotransformation, e.g. 6195 for SAD_1969_96_To_WGS_1984_2. – Kirk Kuykendall Jul 27 '16 at 18:43

  • @raphael to specify the transformation use the project tool rather than an export. The project tool will allow you to specify the transformation – Midavalo♦ Jul 27 '16 at 18:50

    Try setting the default transformation in the gp environment, but you may have to use a gp tool rather than "catalog." – mkennedy Jul 27 '16 at 23:46
