This plugin corrects the elevation of GPS tracks using SRTM
elevation data, which is automatically downloaded from the official SRTM download server. The plugin can also download enhanced SRTM data from Viewfinder Panoramas
where available. In addition, custom elevation data provided by the user can be used for elevation correction. (Users in the United States seeking the most accurate elevation correction are encouraged to use National Elevation Dataset (NED)
data, which can be downloaded from the National Map Viewer
.) All available digital elevation models are listed on the plugin settings page, and the priority between them can be changed. There is an option to automatically correct data at import, plus an option to exclude selected sources from automatic correction, and an option to download elevation data covering all activities in the logbook, so that no further downloads will be needed to correct the activities. The plugin also adds a pointer mode where you can click on the map to view the corresponding elevation (click on Edit and change to Elevation to enable), and an optional activity detail page for comparing elevations (enable from the plugin settings page).
If you wish to use custom elevation data, you will also need to install the GDAL plugin
The downloaded file should have a .st3plugin extension. Some users have reported the downloaded file for this and other plugins being incorrectly renamed to .zip. If this happens to you, just rename the .zip file to .st3plugin.
I use the data from the US National Map Viewer. In my region, eastern Pennsylvania, the data is accurate to the foot. I do some runs on a track with a football field in the middle. The track has a constant evelation at every point and the football field center line is 1 foot higher. One thing I would like is more precision on the distance so I can calulate grades. 0.1 increments is not ehough. Otherwise it is terrific.
Very useful plugin, thank you.
The GPS-Watch showed hundred of meters up and down on a flat round.
With the Elevation Correction it seems to be correct.
Alle wichtigen wetterdaten und noch mehr...
Da bleiben keine Wünsche offen. Funktioniert tadellos
Extremely simple and efficient. A must-have with any GPS device. Simply brilliant.
This is a useful, easy to use plugin and is highly recommended for anyone with a GPS device. The raw GPS data has poor elevation information, which this plugin compensates for
