     The Visual Quality Analysis Model (VQA) is a series of pictures that has a ranking system of 1 to 10, with 10 being the highest value.  Each student will select the value they feel is the best representation for the picture.  These pictures were taken over a period of about 70 years.  They represent one portion of this rangeland over a period of time.  Your job as the student is to rank this rangeland by its given picture according to your knowledge about the given area.  Once your values have been submitted, they will be compared to the class average as well as those of Professors who are experts in the field.
