I was doing my project and I had to transform a shapefile from Bessel to gcs_wgs_1984, that went fine. Now I have to put it again to projected coordinate system.
Please could someone help me transform it from WGS_1984 to UTM wgs_84 zone 33N?
Sure, you should be able to go to Toolbox->Data Management->Projections and Transformations->Feature->Project.
There, simply select your dataset and then click the button for output coordinate system, where you can browse to Projected Cordinate Systems->UTM->WGS 1984->Northern Hemisphere->WGS 1984 UTM Zone 33N.prj and press Open, Apply then OK.
If you press OK again then it should do it. Normally to do a transformation like this, you would have to specify a specific transformation (in the last box), but Arc does not seem to have any valid transformations in this case (for me at least), so I would say that you should be careful to check that it has worked properly (by checking that it lines up properly with some other data).
How is that?
