Re[2]: Generating weather maps

Yes, this would be really useful. I already use a simple sort of
caching, that is generating the map on the first request and storing
it. Every other request in the next half hour gets the cached version
of the map. Image generation itself is quite fast, getting all METARs
takes a lot of time. So perhaps scheduling the METAR fetch might be
sufficient.

Another problem is that I have to fetch the METARs twice - one time in
the map-generating script, the other time in the HTML-page to display
the onMouseOver-Information for every station. Even with the built-in
caching of phpWeather, I still have to query my database two times.
Has anybody got an Idea how to solve this?

Nice idea. World map generation can also be done with the script I
use. We also need positions for every country, so it would
even be possible to generate the ImageMap to select a country
dynamically.
