hi adnan, 1. First stack the multispectral bands except the thermal (band 6) and panchromatic (Band 8). In your case may be 1, 2, 3, 4 Using ERDAS: Image Interpreter ->Utilities->Layer Stack Now you have one multistektral image with 30 m and panchromatic (in Landsat ETM Band 8 ) with 15 m. 2. Fusion the stacked image with panchromatic ERDAS: Image Interpreter -> Spatial Enhancement -> Resolution Merge Select high resolution input as panchromatic image Multispectral as stacked image There are several chose for methods you can tray which one more suitable I hope it will help

layer stake will not improve the spatial resolution of result image right way is image fusion
