Hi, I got involving license of ENVI 5.1. I'm testing it now. I'm have big interest about mosaic tool, specially, color correction option. I'm working with hyperspectral data (CASI images), so my main issue intensity normalization between the lines. I tried mosaic two lines. Each line is aprox 15GB, 48 band image. The mosaic tool worked aprox 1h and then stopped. Finally, no result. Only output file name without information. No header for the file also. I made 3band subset for both lines, then perform a mosaic tool. Result is perfect but only for 3 bands. Now i'm increasing the band subset to see how many bands tool could handle. So, my question. Are some data limits for this tool? If are, what are those limits. How many band image should i use. Best regards, Jevgenijs
