Hello @ValmirSantana The outputs from D2M are all tiff files. Conversion to ECW is not available as this is a licensing restriction from Hexagon. Only Hexagon products can write or update ECW files. If you take the image into ArcGIS Pro you can use the Copy Raster tool to convert to Jp2 which can provide equivalent compression. Personally, I would leave as tiff as it is transportable to other applications. If you just want as backfround imagery then CRF is a faster option than JP2.
