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 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 for 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.
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 (90°) corners.
4. Arc Segment
Adds curvature to line segments by setting a circular or bezier arc.
Creates new vertices by following along an existing feature.
Generates outward directional lines from a center radial point.
Aligning Existing Features
Moves features into a new location without the modification of any vertices.
Spins a feature in a circular motion from a central pivot point.
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.
Updates the vertices from an existing feature using an input digitized line segment.
Exchanges geometry from one feature to another feature.
Increases the length of a line to snap to an existing feature boundary.
Decreases the length of a line to snap to an existing feature boundary.
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.
Adds vertices to a line or polygon at a set distance, offset, or angle.
Inserts vertices at corners to soften corners and reduce jagged edges in geometry.
Dividing and Merging Existing Features
Cuts a polygon into separate features based on an existing line.
Combines two separate features into a single feature.
Widens a point, line, or polygon at a specified distance.
Cuts a line or polygon by distance, percent, or into equal parts.
Splits geometry where features intersect.
Separates a multipart feature into individual single-part features.
Coordinate Geometry (COGO)
COGO (Coordinate Geometry) follows along a traveled path (traverse survey measurements) using direction, distance, and radius.
GIS Editing Tools
In GIS, editing tools play a pivotal role in weaving accuracy and detail into spatial data.
As we conclude our exploration of these tools, it becomes evident that their power extends beyond mere data manipulation.
They are the brushes and chisels that refine the canvas of geographical information, enabling us to craft maps that mirror the intricacies of the real world.
With precision, efficiency, and a touch of artistry, GIS editing tools allow us to shape, update, and maintain geospatial datasets.
This ensures that our maps not only reflect reality but also guide decisions and assist in action in a rapidly evolving world.
