An overview of the Editing toolbox

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

Sometimes data is captured or digitized with an inadequate precision or lack of a snapping environment. This results in polygon boundaries that are not closed (have gaps) or lines that undershoot or overshoot their intended intersection with other lines. You can use some of these tools to address this type of data quality issue. Other editing tools help address vertex density, conflation, and other data issues.



Adds vertices along line or polygon features and replaces curve segments (Bezier, circular arcs, and elliptical arcs) with 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

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.


Simplifies the input features using a specified maximum offset tolerance. The output features will contain a subset of the original input vertices.

Simplify By Straight Lines And Circular Arcs

Simplifies polygon and line features by replacing consecutive line segments or edges with fewer line segments or edges. Lines segments and polygon edges are simplified based on a specified maximum allowable offset. Additionally, circular arcs can be created from consecutive line segments or polygon edges.


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.

Update COGO

Updates the COGO attributes of COGO-enabled line features to match their line shape geometries.



GIS data often comes from many sources. Spatial and attribute differences among various data sources sometimes requires you to resolve the inconsistencies before you can make use of the data. Conflation tools help you reconcile data from multiple sources and obtain the best possible data quality for analysis and mapping.

Related tools



Analyzes the coordinate locations of feature vertices among features in one or more feature classes. Those that fall within a specified distance of one another are assumed to represent the same location and are assigned a common coordinate value (in other words, they are colocated). The tool also adds vertices where feature vertices are within the x,y tolerance of an edge and where line segments intersect.

Delete Features

Deletes all or the selected subset of features from the input.

Delete Field

Deletes one or more fields from a table, feature class, feature layer, or raster dataset.

Other toolboxes also contain tools that are useful in editing and data cleanup workflows including the following:
