How to changes coordinates to lon/lat?

[HelenaAsttrom]

Hey,

I'm a first time user of ArcGis or any GIS software and I've run into the following problem that I do not seem to be able to solve.

I've opened a Landsat image and I need to define the exact location of some dams that I can see in the image in lon/lat coordinates. Now ArcGis shows coordinates in meter units and my problem is that I simply need to change the units of coordinates to lon/lat for the image. How do i do this?

Thank you,
Helena

There are a couple of things that you could do.  You could change the status bar display units by opening the data frame properties > General tab > Units > Display.  Another option would be to project the raster from a projected coordinate system to a geographic coordinate systems such as GCS_1984 using the Project Raster tool.  Lastly, you could create a point feature class or shapefile with the GCS_1984 coordinate system and add points to the map during an edit session.  Then run the Add XY Coordinates tool on the point file and the Lat/Long will be added to the attribute table.
