[aprssig] "The New" WXSVR and Canada

[Gregg Wonderly]

I didn't see any responses to my earlier inquiry.  Google Earth provides a 
simple to use mechanism that allows all kinds of geographic/topographic 
information to be integrated and over-layed into very spectacularly useful displays.

My APRSKML server (http://aprskml.dev.java.net) shows how the APRS-IS and TNC 
streams of APRS packet data can be overlayed onto anything else google earth is 
displaying.

The NWS radar images can be retrieved using the KML formatted data that the NWS 
website provides access to.

I understand this kind of thing is harder to use on the road if you don't have a 
stream to the internet for map data.  But in building spaces of EOCs and other 
static locations, it seems like building tools around the KML mechanisms would 
be a great thing to go after.

How many people are using google earth's facilities for external KML sourced 
data to build complex, overlayed views?
