Output
Why is georeferencing important? - answer-measure or visualize geospatial relationships
perform geospatial analyses
Vector Data - answer-is best for non-continuous types of data

Georeferencing - answer-aligning a single layer to its geographic location or extent
Spatial registration - answer-Aligning/overlaying all layers by their geographic layers so that we can compare across
layers
Map layers at same display scale, covering same geographic area, but showing diff data
