The National

GOLF COURSE IN BELGIUM · 23 HOLES MAPPED

In OpenStreetMap this club has more holes than a single round, or hands out numbers more than once. Which hole belongs to which course is not in the data: the holes carry no golf:course:name. Where that tag is present we separate the courses and show them one by one. Here all holes stand together, and whoever writes the book makes the choice. Tagging the holes in OpenStreetMap settles it for everyone.

The National is a golf course in Belgium. 23 holes are surveyed here from OpenStreetMap, 7,777 yd7,113 m of playing length in total. A par is on record for 18 of the 23 holes, which is not enough for a total. The longest hole is number 18 at 587 yd537 m, the shortest number 19 at 82 yd75 m. Worked out in advance: the distance to the front and the back edge of the green for 23 holes as well as the carry distance over 56 bunkers and 7 water hazards for 22 holes. For 23 holes the elevation change between tee and green is on record as well.

Every hazard carries two numbers: the first reaches its near edge, the second carries past it. Drawn from OpenStreetMap, exactly as the app draws it.

THE HOLES AT A GLANCE

All figures in yards, converted from the metre values in OpenStreetMap.All figures in metres. The length follows the line of play from the back tee to the middle of the green and takes a dogleg with it. Carry distances count from the tee to the near edge and to the far edge of the hazard. The stroke index ranks the holes by difficulty from 1 to 18 and decides where net strokes fall.

ELEVATION CHANGE

For 23 of the 23 holes the elevation profile is calculated. Hole 17 has the most cumulative elevation change along the played line: 14 yd (1 yd up, 13 yd down; -12 yd net tee to green).Hole 17 has the most cumulative elevation change along the played line: 11 m (0 m up, 11 m down; -11 m net tee to green). The basis are official elevation models (BE-VL).

COURSES NEARBY

WHERE THE FIGURES COME FROM

The basis is the map of this course in OpenStreetMap. Lengths, distances to the green edge and carry distances are calculated from it, not copied: every hole is projected onto its line of play and the arc length from the tee is counted. This replaces neither an official course measurement nor the club's scorecard. If you spot a mistake you can report it through the course page in the app, map it in FairwayMapper or correct it in OpenStreetMap straight away. Data as of 2026-09-14.
