Pix4D Desktop generates two types of orthomosaics:
- project_name_mosaic_group_name: Orthomosaic with the type and number of bands of the input images. To generate this orthomosaic, select GeoTIFF Without Transparency in the Processing Options. For more information about this option: Menu Process > Processing Options... > 3. DSM, Orthomosaic and Index > DSM and Orthomosaic.
- project_name_transparent_mosaic_group_name (generated by default): Orthomosaic with one extra band (transparency band), which results in a transparent background of the orthomosaic.
The difference is the following:
|project_name_mosaic_group_name gives a black color value to the no value data pixels.||project_name_transparent_mosaic_group_name does not display color information (it applies a transparent band) to the no value data pixels.|
