【實用生活app】Simple Topo|最夯免費app-綠色工廠好玩App

FREE - NO ADS! Online/offline topo map viewer for the United States. I tried a few of the leading topo apps and didn't like them, so I learned how to use WMS and rolled my own in a weekend.

Simple Topo is so simple it's almost stupid. It simply saves every map tile you see. It uses a Google Map so the gestures and controls are already familiar, but it does not use any Google data. Instead, all map data comes from the public domain USGS National Map. Other topo apps do some sketchy things like like attribute ESRI data to the USGS and then slap their own watermark on it. Not this one! Simple Topo respects copyrights and terms of use.

I wrote Simple Topo for myself, so any improvements I make will be for my own enjoyment and edification. But like most programmers who give their software away, I'm open to suggestions and I love getting feedback. I'm already thinking about intuitive ways to control what is saved and grab tile sets for specified areas and zoom levels.
