 You can use the following free and open source software to open the files generated in ODM:
  * .tif (GeoTIFF): [QGIS](http://www.qgis.org/)
  * .laz (Compressed LAS): [CloudCompare](https://www.cloudcompare.org/)
  * .obj (Wavefront OBJ), .ply (Stanford Triangle Format): [MeshLab](http://www.meshlab.net/)

 **Note!** Opening the .tif files generated by ODM in programs such as Photoshop or GIMP might not work (they are GeoTIFFs, not plain TIFFs). Use [QGIS](http://www.qgis.org/) instead.
