[IDV #QBD-872656]: IDV - idv questions

Hi John,

Yes. In the Data Chooser there should be a "Directory" tab. (Assuming you are 
running 2.0
or 2.1). This allows you to specify a file system directory to look at and to 
select the
latest N files in that directory. Make sure you select "netCDF Point Data Files"
for the Data Source Type. See attached image. You can specify  polling for auto 
updates
if so desired. Also - these same settings  can be accessed from the data source 
properties.

By the way - you should notice a *big* performance improvement over the point 
data reading
that you were experiencing at the summer unidata workshop. We did alot of work
last summer on that.

Assuming you are running IDV 2.1 you can set a spatial subset either in the 
Field Selector
or from the data source properties.

Unfortunately not. For now, we can only access radar and satellite imagery for 
0Z onwards.
