Comparing pictures- Find the differences- Lab 4

Comparing pictures to find the items and missing or changed things has been one of my favorite pastimes.  This exercise was an extensive grownup version of a familiar child's activity.   There's an amazing science which has developed to statistically calculate the accuracy of the human verses the computerized (production) method of classification.   We take an undated aerial of Pascagoula, MS and Moss Point, MS (next to one another) and verify our original land use/land cover classification.  Here we had to split hairs so to speak so if the point did not land exactly on something the spot was invalid.  We did not calculate a "within radius" of any intended target which may have raised the accuracy some.   Anyhow, I was 9/30  at 30 percent, not so bad for the first attempt.  My truthing points were truly placed as quickly and as randomly as possible to keep from having a "selected spot" type bias which likely accounts for many of them landing "out there".   Here's the map and my table of truthing with notes.
