Tip: For Clip, provide an overlay polygon in Layer B. Line features are strictly clipped — we split lines at polygon boundaries and keep only inside segments. For Dissolve, click Scan Attributes to pick a field.

Line features are strictly clipped: split at polygon boundaries and only segments inside the polygon are kept.
Dissolve is optimized for polygons. Points are grouped; lines are merged per group when possible.

Notes:
  • Buffer distance is in meters (turf.buffer).
  • Clip expects B to be polygonal; points are kept if inside; lines are strictly clipped to the polygon (boundary‑split, inside segments only).
  • Dissolve unions polygons (all or by property). Lines are merged per group when possible.
