Adze is a GPS data editor which you can use to edit track points, automatically split tracks at rest-stops, optimize away redundant data, and more.

Features:

• View document, track or selection statistics such as distance, duration or gradient
• Edit document and track metadata
• Export tracks for display in Google Earth
• Clear, offset, sort or overwrite timestamps completely with new values based on speed or start and finish dates
