Vector Topology Repair

When To Use

  • •Use before overlay, dissolve, or network analysis on vector data.
  • •Use when polygons contain slivers, overlaps, or self-intersections.
  • •Use when line features require snapping and connectivity cleanup.

Workflow

  1. •Run topology diagnostics and categorize issue types.
  2. •Repair invalid geometries with deterministic methods first.
  3. •Apply snapping, simplification, or dissolve rules with explicit tolerances.
  4. •Re-validate topology after each repair stage.
  5. •Produce a repair report: counts fixed, remaining issues, and manual-review cases.

Guardrails

  • •Preserve source data by writing repaired outputs as new layers.
  • •Do not use aggressive tolerances without documenting tradeoffs.
  • •Escalate unresolved or ambiguous fixes instead of forcing silent edits.
