Why convert RTMAP to TRK?
An RTMAP (CompeGPS / TwoNav Tiled Raster Map) is a georeferenced raster image - a background map stored as tiles with a companion .imp index file. A TRK file is a GPS track: a sequence of latitude/longitude coordinates showing where someone traveled. One is the map; the other is the path drawn on the map, and a raster image does not contain coordinate sequences.
How to convert RTMAP to TRK
TwoNav Land FREE
Open RTMAP maps in TwoNav Land (twonav.com) and load a separately recorded or downloaded .trk or .gpx file to display the track overlaid on the map - the map and track are separate files, not a conversion.
About these formats
An RTMAP file is a tiled raster map image from TwoNav (formerly CompeGPS). It is not a standalone file - a working map is a set of .rtmap tiles plus an .imp control file that must stay…

Open .TRK details →Quality & what to watch
- RTMAP files contain georeferencing data for positioning the map image correctly, not GPS coordinate sequences - there is nothing to extract as a track.
- TwoNav records movement as a
.trkor.gpxfile during navigation; this file is created separately from the map and must be obtained independently. - A single
.rtmaptile requires the companion.impcontrol file and all sibling tiles to display correctly in TwoNav Land.
Frequently asked questions
Why do search engines suggest converting RTMAP to TRK?
Can I extract location data from an RTMAP file?
.imp control file stores the map's bounding coordinates and projection, not a path or route - you cannot extract a meaningful GPS track from it.Where do I get a TRK file for my TwoNav maps?
.gpx file and open it in TwoNav Land.
