, what is root mean square error 1. and what does it have to do with digitizing or
scanning? - ✔✔it measures accuracy of the transformation and is reported in map units

points,lines,polygons
union - ✔✔combines 2 polygon layers keeping all areas and merging attributes for both
layers
buffer - ✔✔a spatial query that delineates areas that fall within a certain distance of a set
of features
append - ✔✔copies features from 1+ input data sets to a target data set that already
exists
merge - ✔✔combines features of 2+ feature classes and puts them into a new feature
class.
