I have added a few enhancements to the Cave Atlas recently that I feel are good tools.  The first is the ability for you to rate the cave system.  This is simply an overall rating.  My belief that the mean of the ratings will eventually show the true feeling the community has about a system.  The second enhancement I have made is to how regions are handled.  Since the Cave Atlas was originally created for Florida caves the database was designed for County, State.  Later I added Country to handle international and just tweeked the County and State to make it work.  The problem was handling caves in other States in the US.  Well, that has been fixed.  You will now see some caves in Missouri.  In the cave listing, you can simply click on the State name and the list will be filtered to that State. 

A feature that I feel is underutilized is Mapping.  One the Location tab, you are presented with an overview map.  Simply click that map and you will have many, many more options.  A popup window will show a hybrid map from Google Maps.  Look closely and you will see the map style is called "Cave Map".  In some instances, I have created custom tiles that show the actual cave map overlaid on the Google Map.  I recommend checking out Peacock Springs to see this the best.

I am always looking for ways to enhance the Cave Atlas and make it a better resource for everyone.  Please let me know what ideas you have.
