Lab 8

Working with ArcMap to manipulate and work with IMG files taking a basemap and overlaying and image file.

To sattelite image and overlayed it on the basemap and accentuated a portion of them map by using image analysis toolbar. Tools: DRA (exentuate the part of the map I wanted to focus, and clip to take out the piece I wanted then overlaying that on the original. Shown is how to export the clip into a raster file since the clip is not saved just heald in the clipboard. (**important** clips need to be exported this way so they are not lost)

ISODATA cluster unsupervised classification
>spatial analysis tool>multivariate>ISODATA cluster unsupervised classification
made multiple with 16/17(originaly 20 but would only allow 17)/8 to see how each one limits

ISOCLUSTER 1: 16

ISOCLUSTER 2: 17

ISOCLUSTER 3: 8

Each version allowing designated # of categories to the data though lower numbers would not allow for much manipulation later on so if I got farther through my work at need more categories to display would have to start over so planning is important.

Reclassify allowed me to take similiar attributes and combine them results before and after below

Played with display so that I could see the base map underneath changed to a transperancy of 60%

The program manipulated to color but that was maintained in the legend, was not sure how it was done in the lab slides but I think this would be close.

NDVI

Final with addition of data collected during the fieldtrip setup in layout view and added north arrow, legend, scale, and title.
