Introduction

A number of modules are accompanied by small examples. These examples focus mainly on the module itself. The examples on this page use several modules and are more 'real life' examples.

trk2rte

The purpose of the trk2rte example is to accept multiple GPX files with track information, optional optimize these tracks to reduce the number of points in the track and then export all tracks as waypoints and routes in one GPX file or in a OZI waypoint and OZI route file.

For reducing the number of points the trk2rte example uses the angle method: if the bearing of the next segment in comparison with the bearing of the current segment is smaller than the threshold, the intermediate track point is removed.

The trk2rte example uses the following modules:

• snl - Generic Single Linked List
• str - Dynamic Strings
• tos - Text Formatter
• xis - XML Parser
• xos - XML Writer

trk2rte requires FFL version 0.8.0.
