The Map window has some nice (hidden) features. So it is worth a separate post.
What to show
By default the map shows the caches in the active folder. So the caches on the map are the same as the caches listed in the cache list of the main window. When you click on a cache symbol, the cache becomes the selected cache in the main window.
Only the additional waypoints of the selected cache are shown in the map. When you zoom out too far, the additional waypoints are hidden.
When you click on the little triangle button in the bottom right corner, a little panel pops up with some extra options. Here you can select which caches you want to see (all caches in the current Folder, or only the selected ones) and which additional waypoints you want to see.
iCaching has more maptypes to show than listed in the window. There are (standard Google Maps) buttons for roadmap (r), satellite (s), terrain (t) and hybrid (u). In some areas there are also 45 degrees aerial pictures available. You can also toggle between these views by the keyboard shortcuts as listed between brackets. But there are two more maptypes: OpenStreetMap and OpenCycleMap. You can show these by using the o and p keys.
For the time being (but hopefully not for too long), the Map is based on Google Maps. This has as disadvantage that it’s speed is not fantastic when you have a lot of caches. So when you have a big number of caches within iCaching, don’t open the Map when you are in the ‘All Caches’ folder, but from folders with about 3.000 caches max.
