Orthomosaic Bands

PIX4Dmapper
1

The output from Mapper generates orthomosaic that can be used in ArcGIS fine however cannot be used as an image service if using Esri Fields Map, furthermore, CAD such as Rhino or AutoDesk and in some occasssions basic windows explorer window cannot view the images given the orthomosaic is 4 bands (RGB and Alpha).

Is there a setting somewhere I missed that makes the outout to be 4 bands not 3?

I dont think its a setting on the Mapper because the Cloud does the same. The lengthy way to rememdy this is I make a new image using the R, the G and B using tools in the ArcGIS Pro but would ideally want to elimate the extra step.

Hello,

There is not an option to remove the alpha band in either PIX4Dcloud, PIX4Dmapper, or PIX4Dmatic. However, have you tried using GDAL to remove the alpha band? This is a very easy and fast method. You can use GDAL translate to remove the alpha.

gdal_translate -b 1 -b 2 -b 3 input.tif output.tif

As for AutoDesk, our orthomosaic is compatible with Civil3D. However, the MAPIINSERT has a limitation of 128 characters for the complete image file path and the world file path. If the combined length exceeds this limit, the command may fail.

@Rio_Hondo_GIS_Progra just in case this feature is critical for you, in PIX4Dmatic, you can export the orthomosaic without alpha (transparency: Off):

Morning! This is great thank you! But not mapper I assume? For projects with several thousand images and dozen gcp would the matic do fine over the mapper?

Hi @Rio_Hondo_GIS_Progra PIX4Dmatic is more efficient than PIX4Dmapper in processing large datasets. This article is quite outdated, but it shows that already with very early versions of PIX4Dmatic, processing is faster than with PIX4Dmapper - up to 70% faster at the time. Datasets that would typically fail with PIX4Dmapper, due to their size, process smoothly with PIX4Dmatic.

If you end up of testing PIX4Dmatic, please let me know how it goes. You can have a look at this video to get started: https://www.youtube.com/watch?v=mSk4o6rGAf4&t=6s.
