Keeping original thermal DN values in orthomosaic
« on: April 24, 2017, 05:47:16 PM »
I am processing images from a FLIR Vue Pro which are 14 bit. But when I export the orthomosaic generated by Agisoft it is only in 8 bit. I need to preserve the original 14 bit DN contained in the images as these have the raw data I need to convert to temperature. Is it possible to generate an orthomosaic that preserves the 14 bit DNs? Thanks!

Hello julia_geographer,

Are you using any raster transformation when exporting the orthomosaic and which export format you are using?
Best regards,

Thanks Alexey, that was a simple fix just to make sure 'None' is selected under raster transform when exporting as a TIFF file. Thank you for your help and prompt response
