could I request a enhancement to the Dashboard to include distance for the event caches

ie http://geocaching.com.au/dashboard/au/

it makes a just a little easier to determine potential events to visit, I'm not sure we need exact kms just some indication

actually what would be super-cool is a feed that would automatically put these in your calendar via http://en.wikipedia.org/wiki/ICalendar

For performance reasons, the dashboard is cached and therefor is the same for everyone, adding that may cause some issues, however we can perhaps address this when we go to new hardware.

Good idea!

a pity this calculation can't be done on client-side?

that's a very clever idea!

You of course can do the calcs yourself as they are fairly easy

Depending how acurate you want to get... the rough mud math way is to just use pythag (ie right angle triangle) but throw in a cos(latitude) for good measure.

distance in km = sqrt((abs(lon1 - lon2) * cos((lat1 + lat2) / 2))^2 + (abs(lat1 - lat2) * 100)^2)

Of course if you want to get precise you need to use the great circle distance formular, but the above is good enough for most cases.

We have a function in the codebase but as previously stated we don't want to impact on the performance by doing this for individual page reguests.

Or you can use this page

It's just not on the dashboard.

Well do what the other person suggested, put the load on the client side rather than server.

I would prefer not. Javascript is unreliable across browsers, it takes more code to download and not everyone has it turned on. To cater for the most we do it server side. Use the other link which is generated in real time based on your home co-ords.

btw what happens to caches like this... http://geocaching.com.au/cache/ga1037 a FTF still available

Basic math functions aren't questionable, and you can easily use noscript tags for those with it disabled on a per site or entirely.

Most problems with JS is related to displaying, or layout etc.
