GPS Visualizer - online utility


Stumbled across this site the other day:
GPS Visualizer is a free, easy-to-use online utility that creates maps and profiles from GPS data (tracks and waypoints, including GPX files), driving routes, street addresses, or simple coordinates.

GPS Visualizer can read data files from many different sources, including but not limited to: GPX (a standard format used with many devices and programs, including Garmin's eTrex, GPSMAP, Oregon, Dakota, Colorado, & Nüvi series), Google Earth (.kml/.kmz), Google Maps routes (URLs), (.loc), FAI/IGC glider logs, Microsoft Excel, Google Spreadsheets, XML feeds, Garmin Forerunner (.xml/.hst/.tcx), Timex Trainer, OziExplorer, Cetus GPS, PathAway, cotoGPS, CompeGPS, TomTom (.pgl), IGN Rando (.rdn), Emtac Trine, Suunto X9/X9i (.sdf), Fugawi, NetStumbler, and of course tab-delimited or comma-separated text.

GPS Visualizer is based in Portland, Oregon, and has been on the Web since October 2002.
I've played with it, and it seems useful.
