I am trying to create a mosaic from a number of geotiff images. By default, transparent areas are black. If I select band_4 for the alpha channel in symbology, the entire mosaic disappears.
I have tried creating the mosaic with Mosaic To New Raster, and Create Raster Dataset then Add Raster To Mosaic. Both workflows have the same problem.
If I drag and drop a raster onto the map, it works great. The alpha channel uses band_4 by default and the rest of the image is visible.
Is there an ArcPy equivalent to drag and drop? If so, can that be added to a mosaic? Are there other ways to create mosaics that handle transparency better? Am I missing a step that is causing the transparency problem?
Ultimately this needs to be automated. Any help is appreciated.
