choropleth- pre- defined boundaries. This usually contains shading. An example would be a political map like the US States.
isarithmic- Data define boundaries; contour map. (ex: weather map 40’s 50’s)
standard deviation-features are placed in classes based on how much their values vary from the mean
Union-preserves all features from the inputs. The area extent of the output combines the area extents of both inputs
Intersect-preserves only those features that fall within the area extent common to the inputs.
Symmetrical Difference- preserves features that fall within the extent that is common to only one of the inputs (pg. 227) *I don’t know if we need this one, i dont remember ever talking about it in class.
