What is the difference between snapping tolerance and cluster tolerance in ArcGIS Pro?

Used when snapping is enabled to control the accuracy of the pointer. Snapping tolerance aids in aligning, connecting, and measuring features accurately.

Workflows involving a snapping tolerance include editing and digitizing spatial data, as it is useful for ensuring features, such as lines and shapes, are positioned at specific locations or existing features.

Used in topology workflows. Cluster tolerance aids in simplifying complex or large datasets by grouping nearby points together.

Workflows involving a cluster tolerance include spatial data analysis and processing, as it is useful for generalization, reducing the number of vertices, and improving performance.

• XY tolerance – the 2D planar distance between the pointer and a geometric element.
• Z tolerance – the vertical distance between the pointer and the nearest z-value stored with a 3D surface or z-aware feature.

• An x,y tolerance to find vertices within the horizontal distance of one another.
• A z-tolerance to distinguish whether the z-height or elevation of vertices are within the tolerance of one another.
