GeocachingAustPrint

printing Geocaching Caches

Currrent the GeoCaching.com website uses MapQuest data which is fine the the US where these maps have good coverage but for us Ozzies, particularly outside the main Citys there the maps are pretty useless

GreaseMonkey

This is an addon to Firefox [GreaseMonkey website]

The Script

This code will replace the MapQuest graphic when viewing Cache data on the Geocaching.com site "when formatted for Print" . ie you have selected the link which formats the page for print friendly output. Install the script as filename : GeocachingAustPrint.user.js (then open with Firefox) or click here.

This substitutes the lame MapQuest map on cache printout mainly for an
OS map (where MapQuest coverage is not that good)
