From William Modesitt:
Import and view GPS eXchange format (GPX) files. GPX-Viewer views GPX files exported from many GPS devices and other apps that create GPX files. Import the files using iTunes file sharing, your Dropbox account, eMail, an URL, or from iCloud. Choose Apple Maps, Google Maps, OpenStreetMaps, or others. Chart elevation vs. track points or distance. Send the waypoints to Apple Maps. Email the file. Disable screen auto-lock to keep the device from sleeping. Create folders to better organize your GPX files. Set different location tracking modes. Selected routes show as a different color to easily visualize. Hide or show the waypoints on the map. View track points on map. Track points show distances and other values. Show a Google street view of the selected pin (when available). A sample file is included. We also have a GPX Viewer and GPX Editor for the Macintosh computer. Visit our web site for more info.
Edit GPS eXchange format files extracted from GPS devices and saved on mac. The suite supports accessing file content, editing numbers and coordinates, creating copies, viewing and managing waypoint parameters, routes, tracks, etc. Track chart monitoring is included.
