An air carrier pilot reported that his aircraft's egpws detected an obstacle at 15;000' about seventy miles west of veils intersection. A balloon was once tethered at that location but is no longer there. The egpws database accuracy is questioned because of the possible existence of new hazards not in the database.

Narrative:
Just an FYI. On departure off of msy and about 70 miles west of veils intersection our GPWS database indicated [an obstacle] in red numbers '150'. That's a pretty high obstacle down there or anywhere for that matter. I asked the center controller if it was a moored balloon. He indicated that the balloon disappeared during the katrina hurricane and had not been replaced. That was about 5 years ago. How often are the GPWS databases updated?
