This lab focused on the use of Landsat 4 and 5 satellite imagery to conduct remote sensing analysis. I first calculated the Normalized Difference Vegetation Index for a region including parts of Whatcom, Skagit, and Island counties. To do this, I used the Raster Calculator tool with the expression: ((Float(“Near IR Band”) – Float(“Red Band”)) / (Float(“Near IR Band”) + Float(“Red Band”)))
I then conducted a supervised classification of Bellingham to determine different basic landcover types within the city limits. To do this, I used the Image Classification toolbar in ArcMap to create representative samples of each cover type based on false cover Landsat images. The result can be seen below.
