QUICK ANSWER
Is it possible to convert RTMAP to GEOTIFF?
No - not a direct conversion.

No converter exists for RTMAP to GeoTIFF. If you need the map data in an open GIS format, contact the original map publisher and request a GeoTIFF or GeoPackage download directly - most providers offer multiple formats.

Why convert RTMAP to GEOTIFF?

RTMAP is a proprietary tiled raster map format from CompeGPS / TwoNav with no public documentation or open-source parser. A complete map requires multiple .rtmap tiles plus an .imp control file for georeferencing. GeoTIFF embeds coordinate reference system metadata inside a TIFF file and is a widely supported open format. No tool has implemented reading the closed CompeGPS binary to produce GeoTIFF output, because the format has no public specification.

How to convert RTMAP to GEOTIFF

TwoNav Land FREE

Within the TwoNav ecosystem, TwoNav Land can convert .rtmap to .rmap (the single-file format TwoNav recommends) - this does not produce GeoTIFF but keeps the map usable on TwoNav devices.

About these formats

.RTMAP CompeGPS / TwoNav Tiled Raster Map

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…

Quality & what to watch

  • The RTMAP format is closed and proprietary with no published specification, so no GIS tool outside TwoNav can parse it.
  • A complete RTMAP map requires multiple tile files plus an .imp control file - a standalone .rtmap tile has no usable georeferencing on its own.
  • If you need GeoTIFF, contact the original map publisher and request an alternative download format; most commercial and governmental map sources also offer GeoTIFF or GeoPackage.

Frequently asked questions

Is there any tool that converts RTMAP to GeoTIFF?
No - no consumer or professional GIS tool supports this conversion because the RTMAP format has no public specification.
What GIS software can open RTMAP files?
None outside the TwoNav ecosystem - if you need the map in QGIS or similar software, you need a GeoTIFF or other open raster format from the original source.
Can I rename a .rtmap tile to .tif to view it as an image?
A single tile may open as a raw image, but all georeferencing is lost - the result is just a picture with no coordinate information and is not useful for navigation or GIS work.
