What is the <strong>IDV</strong>?<br />
�� Visualization and analysis toolset for<br />
data<br />
�� Freely available Java Java framework<br />
and application – multiplatform<br />
�� <strong>Integrated</strong> 2D/3D/4D displays of a<br />

�� Community driven capabilities
Why use the <strong>IDV</strong>?<br />
Its USEFUL, CUSTOMIZABLE, EXTENSIBLE,<br />
DAZZLING, FUN, and FREE!<br />
“I I was floored at the capabilities of this<br />
software. I've only been looking at for an<br />
hour or two. WOW is all I can say! I'm<br />
surprised nobody has mentioned this before.” before.<br />
<strong>The</strong> <strong>IDV</strong> has the Fastest growing user base in<br />
the international Unidata community

an OpenDAP server. Only the full resolution data in the green<br />
box is loaded on the client. <strong>The</strong> histogram stretch utility has<br />
be used to emphasize land features in band 1.
