It would be nice if GIS info were available to taxpayers! poke. poke.
And if GIS browsing site had more features.
Basic bookmarking/linking would be nice.
Anyone want to write a cloudy app?
It's not fantastically wonderful data really .. maybe,

for (( i=87198 ; i<=88123 ; i++ )) ; do
echo i=$i;
wget -c $BASEURL/$i.jpg ;
done

for (( i=87198,j=0 ; i<=88123 ; i++,j++ )) ; do
ln -s $i.jpg $j.jpg;
done

# -r is framerate in fps, -b bitrate

Ummm... who are you poking?

I'm poking OSI.
Set the data free!
Or at least allow basic datasets available at reasonable cost.

And the Queen of England - Set the tidal data free!
http://www.wxtide32.com/faq.html#faq02

Set it free so people can do stuff with it.
Like sharing/publishing science vs keeping it secret.

Maps for Ireland for SatNav I think are not from OSI because they're too expensive.
The Americans successfully made the argument that the organisations collecting map data were all tax funded so the data belongs to the public.
And it's a reasonable position economically anyway.
You're not going to make tons of money off of basic data anyway especially if you price it off the market.

For basic map data openstreetmap is going to takeover the world anyway Muaghahahahaaaaa :) http://www.openstreetmap.org

Jumping completely off topic almost, these guys have nice new maps (just pdf format): http://www.dublinmountains.ie/home/
