[worldKit-dev] multiple events at single locations

[Bruce Thomas]

Mikel,

Thanks for the link and the info. I didn't realize about the zoom level
effect, and I like your refactor ideas, interesting.

Two questions:

1.) Using <window>_javascript:foobar</window> I get the lat, long, and
idfrom the annotation click, but the
link is missing. I wonder if the link is ignored when not using the
<window>_blank</window> or <window>_self</window> options?

2.) I want RSS 1.0 (RDF) for GeoRSS with one geo:lat and geo:long in each
<item>, and then include several plants collected at that point. Any
pointers?

More about me:

I work at the city of Riverside, California and I'm trying worldKit for
mapping locations of plant
collections<http://www.riversideca.gov/museum/plantcom/plantcom.htm#pcmap>from
San Jacinto Mountains on the Riverside Museum pages. I've been able to
implement a Google map on some of the plant pages as a demonstration
project, and I've shown people the worldKit too. There is more excitment
about the worldKit using topo map images and Landsat WMS, and being able to
click them back and forth instantly (once the Landsat WMS images load of
course). I wish I could make the topo map more or less transparent with a
slider (another refactor idea?). I used  VB.NET, JavaScript, ArcIMS, and
GeoSmart for other sites at the city of Riverside:

Thanks again,
