[IDV #QIA-177254]: UNAVCO IDV viewer

Dave,

While waiting for a fix to the issue described below, there may be a fairly 
simple workaround. Note the earthquake data is available in CSV 
http://earthquake.usgs.gov/earthquakes/feed/v1.0/csv.php.

This can easily be read in to the IDV. For example, enter the 
http://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/all_hour.csv URL in 
the IDV data chooser. You will be prompted to specify the format of the data. 
See more details about this process here 
http://www.unidata.ucar.edu/software/idv/docs/userguide/data/TextPointData.html.

Moreover, you will note that 
http://earthquake.usgs.gov/earthquakes/feed/v1.0/csv.php has many more data 
feed options so this may be a better solution anyway. 

Please keep us up-to-date on your progress.

Best,

Unidata IDV Support
