WTrack

 Features

Edition tools

• Step-by-step edition: Click on map to create new track points, move points by dragging them, and create intermediate points by clicking on grayed markers. Click on a marker to get detailed information about this track step, and get the option to delete it.
• Routing edition: Click on map to set the starting point and destination, the routing engine will automically compute the track following map constraints. Click on the route to create intermediate waypoints that you may drag around.
• Create named waypoints: Click on map to set points of interest. Click on a waypoint to edit its name.

Statistics

Real-time statistic data about your track

• Distance: One way (→) and round-trip (⇆) lenght of the track
• Duration: Estimated duration (one way and round-trip) of the track itinary based on the activity type. This computation is based on elevation profile and my personal experience ;) [hopefully in the future it will be configurable]
• Maximum and minimum altitudes of the track
• Cumulated climbing and descent heights

Compress

• Reduces file size
• Consumes less browser memory and processing, leading to faster editor execution
• Simplifies step-by-step track edition, by only keeping most relevant points

This tools looks at each point in a track, and measures its distance from the line between the previous and next points. If this distance is smaller than the configurable value (eg 5 meters) then the point is deleted.

Elevate / Flatten

Performs bulk operations on track points' elevation:

• Elevate computes the elevation of each point of the track. If an elevation value was already stored, it is overridden with new computed value. Due to the elevation service payment fees, we limit the number of computed elevation values to 512 per track.
• Flatten resets all track points' elevation to zero.

You can display a graphical interactive height profile of your track by clicking on the statistic table at the bottom of the map.

Trim

Trimming is an easy way to quickly delete track points at the beggining or at the end of your track. Select which end of the track you want to trim, then use the slider to define the number of points to remove. The map shows the result in real-time.
