84 traced features across 8 layers for Mystic Oak Golf Course, drawn over NAIP 2019 aerial imagery. The map itself needs JavaScript; the geometry is a plain GeoJSON file either way.

Every figure as published except Card yards (derived), which is summed from the card below and shown only where a published figure is contested; a blank cell elsewhere is one nobody publishes. Front 9 and Back 9 are summed from the per-hole yardages on the scorecard.

The Red tees publish a yardage total the scorecard below does not add up to. Both figures are published and nothing we hold settles which one a round plays to, so the Yards column keeps the published figure, marked contested, and each tee's own yardage row from the card below is summed beside it, marked derived.
