Editing Shapefile Bounding Coordinates

I've been given a new shapefile that is not posting correctly with my other raster and vector data.
I've noted that this new shapefile's geographic (decimal degree) Bounding Coordinates (as viewed in ArcCatalog) appear to be corrupted; my project is over southern Chile in Patagonia.

Can bounding coordinates be edited? I've been trying a number of methods to no avail.

Here is what the Bounding Coordinates look like in ArcCatalog:

Horizontal
In decimal degrees
West: -69.000667
East: -69.000648
North: -0.000420
South: -0.000465

In projected or local coordinates
Left: -74.270841
Right: -72.133334
Top: -46.438227
Bottom: -51.448022

Kind regards,
gleonard

Hi,

I'm sorry that I've taken so long to respond. I was out of the office. I did write up a response on my phone a few days ago, but it didn't get saved and published.

The data has a projected coordinate system assigned to it. When calculating the decimal degree extents, the software takes the projected/local values and unprojects them to the PCS's geographic coordinate system. If you look at the projected/local values, you should see that these are already in decimal degrees. Redefine the data in the appropriate geographic coordinate system, and it will display correctly.

If you want to make a copy that uses a projected coordinate system, use the Project Tool, not the Define Projection Tool or the data's property page in ArcCatalog.
