This morning I wrote a post about how to avoid geocache placement density issues. In a follow-up exchange with a member of the Ontario Geocaching Association I was challenged on whether or not an API to check distances would actually work. That’s when I remembered that perhaps one already exists.
If you have a my.garmin.com account you can already search for geocaching.com caches. This means that Garmin already has access to to the Groundspeak data. Unlike other sites Garmin is in a position to check to see if a cache being listed on opencaching.com is too close to one already listed on geocaching.com. Not only could Garmin check if the geocache was too close they could also return caches that are listed on geocaching.com directly into the opencaching.com interface.
It will be a major advantage for Garmin over the other alternative listing sites if Groundspeak continues to let them access their database as they are now. Questions about number of available caches and density issues go away if Garmin can return the Groundspeak data into the opencaching.com website.
