extract golf course hole, fairway, and hazard geometry from openstreetmap data

Steps
Reference the leisure=golf_course tag for the overall course boundary (clubhouse, parking, ancillary areas) and the golf=hole tag for individual hole ways
Query golf-specific sub-features (golf=fairway, golf=green, golf=bunker, golf=tee, golf=water_hazard, golf=path) via the Overpass API or a planet/regional extract, filtered to the area of interest
Read hole-level tags like handicap (stroke-index ranking 1-18) and par values recorded as gender-specific keys (e.g., golf:par:men, golf:par:women) where mappers have added them
Cross-check completeness using a purpose-built editor like OpenCourseMaps, designed specifically for contributing and reviewing golf course data on OSM
Validate geometry quality manually per course, since golf tagging density and accuracy vary widely by contributor and region
Known gotchas
Coverage is crowd-sourced and inconsistent — many courses have only a boundary polygon with no hole-level detail, while others are fully mapped down to bunkers and greens
Duplicate features are a known issue (OSM help docs warn to update existing hole/fairway ways rather than creating overlapping new ones), so de-duplication logic is needed when aggregating
OSM data licensing (ODbL) requires attribution and share-alike compliance for derived products — factor this into any commercial course-mapping use case
