Public golf, measured.
Every course drawn hole by hole from open map data and 1 m lidar. Every round measured from the watch on my wrist and the card in my pocket. Kept by someone who took up golf in 2025.
Steel Canyon Golf Club, Sandy Springs. Golf features © OpenStreetMap contributors; terrain from USGS 3DEP lidar.
Know the course before the tee time
One page per course, built from the ground up: every hole drawn to scale, how far it climbs or falls, how big each green is and which way it tilts. Rounds add the walk, the pace and the conditions.

Two files per round, and nothing typed twice
The watch and the card each record what only they can. The build works out everything else, the same way every time.
-
The watch records the walk
A GPX file from the watch: the route and the clock, second by second. It knows nothing about golf, so it never holds a score.
-
The card records the golf
Strokes, putts and fairways, copied from the scorecard the same day. Anything not written down stays blank, never zero.
-
The build measures the rest
Maps from OpenStreetMap and USGS lidar, time on every hole, distance on foot. Every total and every trend is computed, never typed in.
Latest rounds
The log starts on the first tee

What you can trust on this site
Measured or absent
Every figure traces to a file: the watch, the card, the map or the lidar. If nothing measured it, the page leaves it out.
The walk, not the ball
Maps show where we walked and rode. No shot tracking, no drive distances, no landing zones.
Each player sets their privacy
Scores publish per player. Heart rate stays private, and a playing partner's never enters the data at all.
An honest beginner
Written by someone new to the game. The progress page will show the bad rounds with the good ones.
