## TrackLogs digital mapping (.trl) (dmtlog)

This format can...

- read and write waypoints

- read and write tracks

This format has the following options: index .

This format can be used to convert files from TrackLogs Digital Mapping. The files have extension .trl and can contain waypoints and tracks.

We have seen three different types of this format. Two are binary and one is an XML based format. All three types are supported by our reader.

### `index` option

Index of track (if more than one in source).

Convert track number 'index' from source into dmtlog format.

The known variants of Tracklog 'digital mapping' files supports only one track per file. If you have more than one track in source (f.e MapSource and many others can do such heavy things), you can specify which track should by used for the conversion.

The default index is 1 (the first track of a possible list of tracks).

An example usage you can find at the ignrando format, which uses option index in same manner.
