I am trying to convert speciality maps for use in avionics software. I have converted the mbtiles to CADRG, and they import and display in the computer software, falconview properly. However I import them into the aircraft they display all black.

 

The only thing I can tell is the CADRG has been exported with. 217 color tables bet pallet, with the last table being 0,0,0 which I think is causing the display to be all black.

 

many ideas with resolving this issue? Thanks.

Hi @alanrcrawford​ it could be that the 217th colour table (used for transparent pixels) is causing the issue. To workaround this you could try writing the raster without transparency to see if that helps. To do so, you would need to use the RasterBandNodataRemover before the writer.
