[IDV #QFA-384481]: Question about typhoon data



Murray,

Here is a better solution. Select declutter and experiment with the Density 
slider to the right of the declutter button. In addition, experiment with the 
zoom level. It is not that the IDV is confused so much as the labels coming 
from the shape file are too dense.

Best Wishes,

Unidata IDV Support
