Hello all, I am trying to create a time-series visualization which shows the progression of a wildfire over the course of ~2 weeks. I started with 3 MODIS single-band rasters (bands 1, 2 and 7) for each day and produced a 7-2-1 composite for each day. I am now trying to display these composites as a comic strip or animation so the growth of the burn scar as the fire progressed can be visualized. My issue is getting these images to have a consistent stretch so that they can be compared accurately and effectively. The range of values for each band do not vary greatly from day to day, except that some days have heavy cloud coverage and/or saturated areas that cause the minimum value to be very far away from the rest of the data. Ideally, I would like to apply a stretch to an image (call it image X) that does not have any extraneous values (no cloud coverage or saturation) and then use that stretch for the other images. More specifically, I wish have the values of the other images that fall within image X's range to be displayed the same way as image X, and the values that fall outside of that range be "grouped together" and displayed all the same color (white, perhaps). What is the best way to do this in ENVI 5.0? I would like to keep the original values, but for display purposes wish to "cut off" these unwanted values. Is there a way to do this in IDL so I can iterate through all of the composites (or a batch process mode in ENVI)? Thanks for your time.
