      Hi,

Here at TopoMerge we provide highly detailed maps for your next adventure.

We have developed a process that takes 7.5 minute USGS topographical maps and merges them into a single GeoPDF that is fully geo-referenced.

TopoMerge maps are intended to load directly into the Avenza mapping app.
      
      
      
      Maps can be created from one of two methods.
      
      
      
      1. Supply us with GPS coordinate's and a desired radius.

2. Send us a set of GPS tracks(.gpx) which we can use to reverse engineer a map, permanently burning your tracks into the map if you wish. See the sample.
