<section><title>Apply DEM data</title>
<para>
If any DEM data is loaded, this will apply the DEM data to give the track elevation data.
+Two ways of applying DEM data are offered:
+<orderedlist>
+<listitem><para>Keep. Retains the existing elevation data of trackpoints and only those missing an elevation value are set.</para></listitem>

+<section><title>Smooth Missing Elevation data</title>
+<para>
+In various locations across the world, there are missing DEM values (AKA DEM Holes) from the SRTM data.
+This is particularly noticeable in mountainous areas.
+Two ways of applying elevation data to trackpoints that do not have elevation values are offered:
+<orderedlist>
+<listitem><para>Interpolated. Missing elevation data is interpolated between the previous and next known values.</para></listitem>

+Converting from a Track to a Route may involve a loss of information, in particular timestamp values (hence you are required to confirm this operation before it happens).

+<title>Anonymize Times</title>
+<para>
+Timestamp information of a track can be shifted to be all offset from 1901-01-01.
+</para>
+<para>
+Thus the timestamps themselves will no longer reveal exactly when a track was taken.
+However the relative difference between the timestamps is kept thus one is still able to calculate some properties such as speeds along the track.
+</para>
+<para>

+This is not available for routes, as they have no timestamps.
