Learning Objectives:
Identify situations in which shape affects geometric operations
Develop a method for describing the shape of a cluster of similarly valued points by using the concept of the convex hull
Develop an algorithm to determine the skeleton of polygons
Find centroids of polygons under different definitions of a centroid and different polygon shapes
Calculate several different shape indices for a polygon dataset
Compare and contrast different shape indices, include examples of applications to which each could be applied
Explain what is meant by the convex hull and minimum enclosing rectangle of a set of point data
Exemplify situations in which the centroid of a polygon falls outside its boundary
Explain why the shape of an object might be important in analysis
