20041231: Plotting Research Data
- Subject: 20041231: Plotting Research Data
- Date: Mon, 03 Jan 2005 11:24:59 -0700
Eric,
No, the GEMPAK data management file only stores lat/lon data
to 2 decimal point precision, so plotting the location data or
storing to higer resolution is not possible. It is possible to
store the DMS data as data, for manipulation there, such as
calculations you might do with, but as location information only
2 decimal points will be used.
