On aviation mapping  compression image maybe not decode because of wireless transmission interference. UEP(Unequal Error Protection) scheme is put forward about layer and block structure of JPEG2000 image compression method  flexibly enhances local reconfigurable image's quality which is in favor of identifier in the region of interest. 2008 IEEE.  and realizes three degrees UEP of data block  data header  image data via various degrees correction-coding under the condition of obstruct  naked and shade. BCH  RS and Hamming coding are simulated  and image decoding success rate and image's quality are analyzed according to different coding and ROI (Region of Interest) in the Gaussian white noise model and rayleigh fading model. Results shows that the method we putted forward roughly improves decoding success rate  at the same time  almost not increasing bandwidth
