[IDV #TTT-288053]: Attempting to load point data into IDV



Greetings Eddie,

Try adding this header to the beginning of your text file:

(index)->(Time,Latitude,Longitude)
Time[fmt="MM/dd/yy 
HH:mm"],Latitude[unit="degrees_north"],Longitude[unit="degrees_east"]

Once you have the data loaded, you can manipulate the symbol using the
layout model editor:

http://www.unidata.ucar.edu/software/idv/docs/userguide/tools/StationModelEditor.html

In order to get the upside down triangle, add a "shape" to the layout model, 
then
double click it in the editor. In the popup box that appears, click on the 
"Rotate about
Z axis" tab. In the "Rotate By Parameter" box, enter Default, and then in the 
"Degrees"
boxes at the bottom of the tab, enter 180 into both.

Let me know if you get this to work,

Sean

PS: I noticed you are using an old version of the IDV; you should upgrade to the
latest version (4.0u1). After June 1st, you will no longer be able to access 
data
on our data server unless you've upgraded, due to changes in the THREDDS
and netCDF-Java software.
