This data is suitable for my questions because it has an isolated bedrock with 1 arc second resolution for the California coast. Because the ETOPO data is in different resolutions it is important to pay close attention to the arc second vs. arc minute resolution. For the purposes of this analysis, 1 arc second data will be used because it has the highest resolution.  I will look for topographic anomalies by using imaging processing techniques on the shape files.  I will establish a search criteria through image processing (histogram matching/analysis) for "man-made" interventions - ultimately leading to machine learning (this is very ambitious, and would be happy if I could just begin to compare a few histograms).
