ArcMap Geoprocessing: Creating Buffers and Erasing Features with ArcToolbox

Geoprocessing is a GIS operation that automates many data transformation tasks. A buffer creates a new spatial representation of a point, line or polygon that encloses the feature at a specified distance. The erase tool removes parts of features from other features.

To use data from this task sheet, visit the NRGIS website and follow these links: under State-wide Data click Administrative and Political Boundaries > Iowa_border, and under State-wide Data click Recreation > Trails.

For more information on the NRGIS website, consult task sheet PM2082-09Q regarding Downloading from the Iowa DNR.
