Zeppe,
There were enough little annoyances that looked they would take a long
time to fix and a lot of custom programming that I decided to go with
OpenLayers as the front end interface to my KaMap backend "tiling machine".
This gives a much more googlemaps-ish interface, and Paul Spencer
blessed the union back in the Summer :-)
My understanding is that kamap is positioning itself as a tiling
mechanism, perhaps the one that satisfies the description at
http://wiki.osgeo.org/index.php/Tile_Map_Service_Specification
:-)
Here's a site that I am using to test the latest code from CVS,
http://geospatial.research.pdx.edu/~bjpd/openlayers/examples/ngmdb4.html
We'll be putting a version on the USGS production site within the next
week or two at http://ngmdb.usgs.gov/ngm_compsearch_map.html, replacing
the kamap IFrame that you see there and adding a bunch of "AJAX-y" stuff
like immediate updated number of hits in the database for the current
search criteria.
Basically every time the user moves the map or zooms, the extents are
updated a query is sent off to the database to find out how many records
we have for that area.
Let me know if you want more info on OpenLayers/Kamap config. I actually
promised to put something together, and have been remiss in doing so!
Cheers,
Percy
