## 25 Must-Know Editing Tools in GIS

There are countless ways you can slice, dice, and edit data in a GIS. Densify, simplify, smooth, planarize, trim, fillet, divide, and explodeâ€¦ 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 Segment

Constructs straight line segments by pointing and clicking each vertex.

#### 2. Streaming Freehand

Generates vertices based on the movement of the mouse pointer.

#### 3. Right-Angle Segment

Squares off edges for all line segments forcing orthogonal (90Â°) corners.

#### 4. Arc Segment

Adds curvature to line segments by setting a circular or bezier arc.

#### 5. Trace

Creates new vertices by following along an existing feature.

#### 6. Radial

Generates outward directional lines from a center radial point.

### Aligning Existing Features

#### 7. Move

Moves features into a new location without the modification of any vertices.

#### 8. Rotate

Spins a feature in a circular motion from a central pivot point.

#### 9. Scale

Resizes a feature proportionately in size by either increasing or reducing it uniformly.

### Reshaping Existing Features

#### 10. Edit Vertices

Selects, adds, deletes, and moves vertices from an existing feature.

#### 11. Reshape

Updates the vertices from an existing feature using an input digitized line segment.

#### 12. Replace

Exchanges geometry from one feature to another feature.

#### 13. Extend

Increases the length of a line to snap to an existing feature boundary.

#### 14. Trim

Decreases the length of a line to snap to an existing feature boundary.

#### 15. Fillet

Adds 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. Densify

Adds vertices to a line or polygon at a set distance, offset, or angle.

#### 18. Smooth

Inserts vertices at corners to soften corners and reduce jagged edges in geometry.

### Dividing and Merging Existing Features

#### 19. Split

Cuts a polygon into separate features based on an existing line.

#### 20. Merge

Combines two separate features into a single feature.

#### 21. Buffer

Widens a point, line, or polygon at a specified distance.

#### 22. Divide

Cuts a line or polygon by distance, percent, or into equal parts.

#### 23. Planarize

Splits geometry where features intersect.

#### 24. Explode

Separates a multipart feature into individual single-part features.

### Coordinate Geometry (COGO)

#### 25. Traverse

COGO (Coordinate Geometry) follows along a traveled path (traverse survey measurements) using direction, distance, and radius.

Thank you for this product

Hi there,

Would you mind sending me any update information.

Instructions on how these tools can be used in a software environment (e.g., QGIS) would have been helpful.

How is this a handy guide? There’s no content, no instructions on how to do these techniques or use these tools, lol.

Thank you. This is indeed a handy guide.
