GIS 4035 - Final Project - Estuary Comparison - Sediment Deposition

For the final project of Photo Interpretation and Remote Sensing we were tasked with performing manual or automated image processing techniques on remotely sensed data. The landsat imagery for this project was obtained from USGS.com utilizing their GIS database known as Earth Explorer. The imagery I chose was captured by the Sentinel II satellite. Preprocessing techniques for this project involved clipping, scaling and visualizing the imagery to assess for estuary location, bay shape, water color gradient, and tidal influx/outflux.Programs utilized to perform this analysis included Erdas Imagine and ArcMap. Utilizing Erdas Imagine I was able to perform a supervised classification for the study areas of Pond 6 and Saultsman Cove.
 

Utilizing ArcMap I was able to create the following map deliverable, a combination of two maps showing study area, supervised classification, state extent, and spectral Euclidean distance for the two selected estuaries. An overall dark Euclidean distance output being indicative of pixels that have a higher likelihood of being classified correctly. My map, displayed below, contains not only all deliverable map elements including scale bar, north arrow, study area extent, legends, credit, and author, but also class area and total area derived from tables created and imported from Excel after analyzing attribute table data added in Erdas for each respective study area. In conclusion, I found this project to be an accurate assessment for testing an array of GIS skills related to land use land classification. In performing this sediment deposition analysis I have learned that by analyzing pixel coloration one can determine sediment deposition accurately. Sediment deposition rate was assessed for by analyzing the area values for high, medium, and low sediment classifications for each respective study area, and Pond 6 was found to have a higher chance at silling up the quickest.
