-==== How to add elevation data to a track ====
-\\
-----
-Elevation data are downloaded from internet, so in order for this process to complete you need to have internet connection in your device. Before the actual process of adding elevation data into a track we strongly recommend you creating a copy of a file which contains this track, if you also want this new elevation data to overwrite original elevation data in the file.
-Below are steps describing how to add elevation data to a track in GPX Viewer PRO:
-  - Open **left main menu**.
-  - Tap on **Track/route info** button.
-  - In **Track/route info** screen tap on **...** button and from menu select **Add elevation data**.
-  - If track already contains elevation data, GPX Viewer PRO will show you dialog if you want to overwrite this elevation data with new elevation data from internet. If you want this, then tap on button **Yes** in the dialog.
-  - After a while (adding elevation data can take up to 1 minute, but it depends of how many track points track contains and where it is located) elevation data will be added and GPX Viewer PRO will show you a dialog if you want overwrite elevation data in file which contains this track.
-  - We strongly recommend you creating a copy of a file which contains this track if something went wrong in the process or if you won't be satisfied with elevation data precision. If you have done so, you can tap on button **Yes** in this dialog.
