### 25 Must-Know Editing Tools in GIS

There are countless ways you can slice, dice, and edit data in GIS.

Densify, simplify, smooth, planarize, trim, fillet, divide, and explode… You can do so much!

So, that’s why we’ve created this handy visual guide with the essential GIS editing tools.

From basic to advanced editing, this is your cheat sheet to creating and modifying GIS data.

And if we missed any of the essential editing tools, don’t forget to let us know with a comment below.

### CREATING FEATURES

## 1 Straight SegmentConstructs straight line segments by pointing and clicking each vertex. |
## 2 Streaming FreehandGenerates vertices based on the movement of the mouse pointer. |

## 3 Right-Angle SegmentSquares off edges for all line segments forcing orthogonal (90°) corners. |
## 4 Arc SegmentAdds curvature to line segments by setting a circular or bezier arc. |

## 5 TraceCreates new vertices by following along an existing feature. |
## 6 RadialGenerates outward directional lines from a center radial point. |

### ALIGNING EXISTING FEATURES

## 7 MoveMoves features into a new location without the modification of any vertices. |
## 8 RotateSpins a feature in a circular motion from a central pivot point. |

## 9 ScaleResizes a feature proportionately in size by either increasing or reducing it uniformly. |

### RESHAPING EXISTING FEATURES

## 10 Edit VerticesSelects, adds, deletes, and moves vertices from an existing feature. |
## 11 ReshapeUpdates the vertices from an existing feature using an input digitized line segment. |

## 12 ReplaceExchanges geometry from one feature to another feature. |
## 13 ExtendIncreases the length of a line to snap to an existing feature boundary. |

## 14 TrimDecreases the length of a line to snap to an existing feature boundary. |
## 15 FilletAdds curvature at the bend of two line segments by creating a circular path. |

## 16 Generalize (simplify)Removes vertices from a line or polygon reducing the complexity of a feature – while maintaining the basic shape. |
## 17 DensifyAdds vertices to a line or polygon at a set distance, offset, or angle. |

## 18 SmoothInserts vertices at corners to soften corners and reduce jagged edges in geometry. |

### DIVIDING AND MERGING EXISTING FEATURES

## 19 SplitCuts a polygon into separate features based on an existing line. |
## 20 MergeCombines two separate features into a single feature. |

## 21 BufferWidens a point, line, or polygon at a specified distance. |
## 22 DivideCuts a line or polygon by distance, percent, or into equal parts. |

## 23 PlanarizeSplits geometry where features intersect. |
## 24 ExplodeSeparates a multipart feature into individual single-part features. |

### Coordinate Geometry (COGO)

## 25 TraverseFollows along a traveled path (traverse survey measurements) using direction, distance, and radius. |
