Explain why the process “dissolve and merge” often follows vector overlay operations
Outline the possible sources of error in overlay operations
Compare and contrast the concept of overlay as it is implemented in raster and vector domains
Demonstrate how the geometric operations of intersection and overlay can be implemented in GIS
Demonstrate why the georegistration of datasets is critical to the success of any map overlay operation
Formalize the operation called map overlay using Boolean logic
Explain what is meant by the term “planar enforcement”
Exemplify applications in which overlay is useful, such as site suitability analysis
AM-03 - Buffers
Compare and contrast raster and vector definitions of buffers
Outline circumstances in which buffering around an object is useful in analysis
