Start Gmap4 and display a topo map on smartphones, tablets or computers

This link starts Gmap4 and displays a high resolution topo map centered on Yosemite Valley California.

Gmap4 can display topo maps on iPhones and iPads and other smartphones and tablets. Do you have an Android cell phone? Yes, Gmap4 can display topo maps on Android mobile devices. The same Gmap4 link will also open on laptops and desktop computers. All of this is possible because Gmap4 is a browser app, not a native app. It works in most browsers on most devices.
