> Dear Unidata:
> 
> IDV is a great tool for viewing and analyzing satellite data.  I commonly use 
> it to display and mark volcanic ash clouds using the Drawing Tool.  When I 
> try to write the lat/lon coordinates of a polygon to a .csv file  however, I 
> notice that the coordinates are written to only a precision of 0.1 degrees.  
> The screenshot below illustrates the problem.

> Is there an easy way to increase the precision of the coordinates when 
> writing them out?

You can increase the precision by changing the preference:

Edit > Preferences, and Format & Data, you can increase the precision there.
