The South African National Mapping Agency acquires multispectral imagery (R,G,B and NIR)and currently compresses its aerial imagery with JPEG compression with a TIF wrapper. So we give out JPEG (Q3) compressed TIF files. This has a serious limitation in that it does not support 4 band compression. Due to this limitation we give our RGB.tif as well as CIR.tif. This situation has obvious duplication of bands.
We are thinking of moving to 4 band JPEG2000 compression for our workflow as well as giving clients 4 band orthorectified jp2 imagery.
Does JPEG2000 support this 4 band combination of (R,G,B,NIR) ?
