Photo Interpretation and Remote Sensing - Mod 3
This week's lesson was to classify a TIFF image to Level II. A polygon shapefile was created and two fields, Code and Code_Descr added to the attribute table. Next an editing session was started and the boundaries for the different classifications needed to be digitized. Digitizing each of those islands was a very long, drawn out process, but the most difficult part was determining how to classify everything. So many things could be either one thing or another. Fortunately most of what I was uncertain about fit into the same category so I didn't have to make a final determination. If I had had to drill down to Level III there were several things I wouldn't have known how to classify. There were a couple buildings that could have been schools, hospitals or nursing homes. Fortunately they all belonged to the Level II Commercial and Services category so I didn't have to decide.
This lesson was pretty intense. There was a lot of reading material to cover and so much information it was difficult to absorb it all.
