I have something that appears to be working. The steps are as
follows:
Create map
Add one time listener for tilesloaded
in tilesAreLoaded() {
create kmlLayer
add one time Listener for defaultviewportChanges
start window timeout
}
in kmlViewportChanged() {
stop the windows timer
enable rest of kmllayer
}
in window timer function {
delete timed-out kml layer
reload kml layer
}
You can see this code in action at
http://www.jtphillips.com/cgi-bin/AtcInspectionForm.cgi
but you need to complete the steps select a State, select Segment,
select line, and then
apply before the page includes the java scrip.
