I've had the iPod Touch app of this program for a couple years. It's pretty neat, and I've used it to good profit.
A couple suggestions for improvement:
1. There should be some way to show the ocean if the peak is close to it. The intro panorama from Mount Woodson does not show the Pacific at all (nor does it show Clemente and Catalina Islands).
2. The views do not go to their maximum extent. For example, check out the summit panorama from Mount Whitney and then compare it with the one Jonathan de Ferranti has generated at Viewfinder Panoramas:
http://www.viewfinderpanoramas.org/panoramas/AME/WHITNEY-N.gifhttp://www.viewfinderpanoramas.org/panoramas/AME/WHITNEY-S.gifEverything over about 125 miles out does not show up on the PeakFinder program, most notably Charleston Peak, San Gorgonio Mountain, and Mount San Antonio (Mount Baldy). I saw Charleston and Baldy myself from Whitney 2 yrs ago (and MAYBE Gorgonio). Granted, this type of view doesn't show up most of the time, but for those of us devoted to long lines of sight, it can be a little frustrating not seeing these distant peaks on the software.
http://www.heywhatsthat.com provides a good way to see on a map what is visible from the top of a peak. It remains to convert that to a "landscape format" much like what this program and Jonathan has done......
It is my hope that perhaps these issues can be further addressed, but substantially I greatly approve of this software! Thanks for creating it.
