The script I developed stacks and mosaic satellite imagery, and the resultant imagery is in some cases "50GBs" in size. Therefore opening the image in a GIS environment to check the mosaic is sluggish and slow.
Is there anyway I can quickly create a JPEG/PNG overview/preview (it can be very coarse) of the big mosaic so that the users can quickly check the imagery using the preview file instead of opening/loading the 50GB image mosaic?
