Does anyone know how to load the new proprietary MRR files using QGIS or GDAL?

I tried using Add Vector Layer but QGIS did not recognize this file.

  • I believe that the mrr file is a raster format. So opening as a vector certainly won't work. I don't think that mrr is yet supported by GDAl and therefore probably isn't supported by QGIS. I also think the mrr has been around since 2015 so I'm not sure it's that new anymore either. – MappaGnosis Mar 14 at 17:36
  • Thank you. SAFE (FME Server) has a reader for MRR but not sure if it is free. Is there any tool that is free to read such proprietary formats? – transume Mar 14 at 20:55
  • I would suggest not using the .mrr format any more. It is not supported by GDAL and does not look like support is coming for it anytime soon. Mapinfo usage is lower than ever and I am not sure there is any demand for the .mrr format. The only software that supports MRR is MapInfo and FME. Find a license for either somewhere and convert all your .mrr to something more compatible like .tif, .asc or .flt would be the best option. trends.google.com/trends/explore?date=today%205-y&q=mapinfo – MapInfoNewbie Mar 14 at 22:56
  • GDAL has supported all the functionality that mrr purports to offer (multi-resolutions, sparse-raster, massive data etc) for many years (and for longer than mrr has been around in most cases) but in common formats such as BigTif, ECW and MrSID etc so I suspect that is why the mrr format hasn't really taken off. If you need this sort of functionality - I'd stick with GDAL as it is not only the de facto tool set for OpenSource GIS but is also the tool set used under the hood by ArcGIS (and possibly others)! – MappaGnosis Mar 15 at 9:19

.mrr is the MapInfo Multi Resolution Raster and you need MapInfo Pro to be able to create these. It's an additional specific licence over the normal software (usually).

In QGIS you will also have the same issue with there new extended tab format - you need 64bit MapInfo.

It's basically their version of the OGR VRT format.
