Hi Kristian > Full Name: Kristian > Email Address: address@hidden > Organization: IMEDEA > Package Version: 2.6u2 build date:2009-02-13 19:03 UTC > Operating System: Linux > Hardware: Java: home: /usr/lib/jvm/java-6-sun-1.6.0.07/jre version: 1.6.0_07 > j3d:1.5.2 fcs (build4) > Description of problem: > > We are trying to do "Vector plan view" of the variable derived Flow > Vectors and we get the following error: The problem is that the u and v are on different lat/lon points so the IDV needs to resample the v to the u points. To do that, you need to have more than one level selected. By default, the IDV only selects the first level for plan views to avoid a lot of data downloading. You can select 2 or more levels from the Levels subset tab or select All levels. If you are going to look at several levels, I would suggest the latter. However, be aware that you will have to download a lot of data for all the timesteps/levels.
