 +===== How to export statistics and graphics data? ===== 
 +\\ 
 +Before computing statistics and displaying graphics of a track, the application will process its raw data (usually recorded using the GPS) based on the chosen settings to remove recording inaccuracies and discrepancies. You can export the processed data in a .CSV file: 
 +  * In the details view of a track, click on the action menu {{:​icon_01.png?​nolink}};​ 
 +  * Select ''"​**Export as...**"''​ {{:​icon_02.png?​nolink}};​ 
 +  * Choose ''"​**CSV file / Profile (Data file)**"''​ {{:​icon_03.png?​nolink}}. 
 + 
 +{{:​icon_help.png?​nolink}} After the export, you can easily share/​upload the generated file using the ''"​**Share**"''​ button. 
 + 
 +{{ :​en:​help:​v2:​landmarks:​statistics-4.jpg?​nolink }} 
 + 
 +The following fields are exported: 
 +  * ''"​**Longitude**"''​ and ''"​**Latitude**"'',​ the coordinates of the location buckets in the WGS84 (GPS) datum. A location bucket is a set of one or more locations from the original track, grouped together for algorithmic reasons; 
 +  * ''"​**Distance**"'',​ the cumulative distance from the start point of the buckets, in meter (m); 
 +  * ''"​**Time**"'',​ the cumulative time from the start date of the buckets, in second (s); 
 +  * ''"​**Elevation**"'',​ the mean elevation values computed for the buckets, based on the GPS altitude values, in meter (m), over the EGM96 (Geoid) ellipsoid;​ 
 +  * ''"​**Speed**"'',​ the mean speed values computed for the buckets, in meters per second (m/s); 
 +  * ''"​**Slope**"'',​ the mean slope values computed for the buckets, in percent (%); 
 +  * ''"​**Sea-level pressure**"'',​ the calibrated, sea-level equivalent mean pressure values computed for the buckets, in hectopascal (hpa); 
 +  * ''"​**Pressure**"'',​ the un-calibrated,​ raw mean pressure values computed for the buckets, in hectopascal (hpa); 
 +  * ''"​**Barometric elevation**"'',​ the mean elevation values computed for the buckets, based on the pressure values, in meters (m), over the EGM96 (Geoid) ellipsoid;​ 
 +  * ''"​**Accuracy**"'',​ the mean accuracy (with a 68% confidence) values computed for the buckets, in meter (m); 
 +  * ''"​**Elevation (diff.)**"'',​ the mean difference values between the GPS elevations and the barometric elevations for the buckets, in meter (m);

 The gain is an important value that helps to appreciate the overall profile of a track. A small gain means that the track is mostly flat, a high gain means you'll have to climb a lot. The gain is an important value that helps to appreciate the overall profile of a track.
