An overview of the Editing toolbox

The Editing tools allow you to apply bulk editing to all (or selected) features in a feature class.

Many of these tools fall into data clean-up category, for example, after data is captured or digitized with an inadequate precision or lack of a snapping environment resulting in polygon boundaries that are not closed (have gaps) or lines that undershoot or overshoot their intended intersection with other lines. To Editing tools provide rich set functionality to quickly address these types of data quality issues.

Tool	Description
Densify	Inserts vertices along line or polygon features. Also replaces curve segments (bezier, circular arcs, elliptical arcs) with densified line segments.
Erase Point	Deletes points from the input that are either inside or outside the Remove Features, depending on the Operation Type.
Extend Line	This tool extends line segments to the first intersecting feature within a specified distance. If no intersecting feature is within the specified distance, the line segment will not be extended. Tool use is intended for quality control tasks such as cleaning up topology errors in features that were digitized without having set proper snapping environments.
Flip Line	Reverses the from-to direction of line features.
Generalize	Simplifies the input features using the Douglas-Peucker simplification algorithm with a specified maximum offset tolerance. The output features will contain a subset of the original input vertices.
Snap	Moves points or vertices to coincide exactly with the vertices, edges, or end points of other features. Snapping rules can be specified to control whether the input vertices are snapped to the nearest vertex, edge, or endpoint within a specified distance.
Trim Line	Removes portions of a line that extend a specified distance past a line intersection (dangles). Any line that does not touch another line at both endpoints can be trimmed, but only the portion of the line that extends past the intersection by the specified distance will be removed.

Tool	Description
Integrate	Integrate is used to maintain the integrity of shared feature boundaries by making features coincident if they fall within the specified x,y tolerance. Features that fall within the specified x,y tolerance are considered identical or coincident.
Delete Features	Deletes features from the input feature class or layer. If the input is a layer with a selection, only the selected features will be deleted. If the input is a geodatabase feature class or shapefile, all features will be deleted.
Delete Field	This tool deletes one or more fields from a table, feature class, feature layer, or raster dataset.
