I use the app PeakFinder all the time and it’s incredible for determining what mountain is what when you’re on the go!

I used to use PeakFinder, but then it was withdrawn and the free version disabled. Now it costs $5.

Someone spent lot of time on developing it. This is one app that is absolutely worth $5.

I’d like to be able to determine the location of a landscape photo. Should be able to calculate the panorama for 5x5 mile regions of earth, and use some matching algorithms to find the closest profile to my picture.

I thought about this when watching geowizard:

There is a widely spread myth that Mt. Diablo in Oakland has the second largest viewshed in the world after Mt. Kilimanjaro[1]. With this tool you can actually compare them directly, which is pretty cool: Mt. Diablo: https://www.heywhatsthat.com/?view=K1JW43D4 Mt. Kilimanjaro: https://www.heywhatsthat.com/?view=ME9CTRPG 1: Debunked here: https://www.kqed.org/news/11808501/does-mount-diablo-have-th...

Mt. Diablo is in Contra Costa County, not Oakland.

Thanks for the correction. It felt a lot closer, but I haven't been there in a long time.

The way of getting the land area of the viewshed from this presentation is not immediately obvious.

My non-scientific method was to put the two windows side-by-side, and click the "zoom out" button three times to eyeball the difference.

I can never remember what the name of this site is when I need to use it. I should set up a redirecting domain.

One thing I constantly look for in new place is where can I see sunsets? Where can I see unobstructed views of town? Which hill in San Franscisco can I climb to see panoramic sunset?

It would be great to take this tool to next level to answer such questions.

What about Mt. Taranaki?

Mostly ocean, but it seems to cover a wider area.

I was thinking the same thing. I recently found apps that let you see the direction of sunrises and sunsets (as well as moon directions) for any given location, but you wouldn't really know if the view is obstructed.

Thanks so much for sharing, their website has just helped me to better understand the horizon of my city. https://www.peakfinder.org

Thanks! I've been looking for an app like that....
