provides a framework and tools for performing analysis and managing geographic data

two primary uses of geoprocessing

perform specific task or chain together sequences of tools

7 geoprocessing tools

extracts a subset of one feature class using one or more of the features in another feature class

features or portions of features which overlap in all layers and/or feature classes will be written to the output feature class

used to know the area in common among multiple feature classes

useful when conducting a land use and land cover change analysis across different periods

all features and their attributes will be written to the output feature class

output feature class will have all features from the input data, including attributes

combines multiple input feature classes of the same data type into a single, new output feature class

tends to aggregate features based on specific attributes

creates an area specified distance

only those portions of the input features falling outside the boundaries are copied to the output feature class

attributes of the original features are preserved in the output feature class

useful when your input datasets have different attribute structures

output feature class will have all features from the input data, including attributes.

create new polygons if the input feature classes contain overlapping features

useful when your input feature classes have the same attribute structure

output feature class will have the same attribute structure as the input data and contain the features from both feature classes
