Day 3: Wednesday, July 8, 2015

This morning I used ENVI for several hours to try to understand it.  I downloaded new satellite data from the USGS website, then used several image sharpening systems to practice with them.  Image sharpening algorithms take some time to process the images, so in the future, cropping the images before this stage should greatly reduce the processing time.  After lunch, I spent the remainder of the day attempting to layer the bands into a single file to facilitate data manipulation.  Although my attempts were in vain, I did figure out many of the less intuitive functions of ENVI such as topographic mapping, band algebra, and regions of interest (and their corresponding functions).
