## FC-18 - Adjacency and connectivity

Learning Objectives:
• List different ways connectivity can be determined in a raster and in a polygon dataset
• Explain the nine-intersection model for spatial relationships
• Demonstrate how adjacency and connectivity can be recorded in matrices
• Calculate various measures of adjacency in a polygon dataset
• Create a matrix describing the pattern of adjacency in a set of planar enforced polygons
• Describe real world applications where adjacency and connectivity are a critical component of analysis
