Green/FW transition made easy

[sandsaver01]

Ariel - one way you can get the widths you want using Lidar is to put Chadgolf's little "Splines.json" program into your course file (see whole file below) and edit the widths and secondaries as you want them.

{
"bunker": {
"pathWidth": 1.7,
"handleLength": 1.0,
"tightSplines": true,
"secondarySurface": "",
"secondaryWidth": 2.5
},
"green": {
"pathWidth": 1.7,
"handleLength": 0.2,
"tightSplines": true,
"secondarySurface": "rough",
"secondaryWidth": 2.5
},
"teebox": {
"pathWidth": 1.7,
"handleLength": 2.0,
"tightSplines": true,
"secondarySurface": "rough",
"secondaryWidth": 3.5
},
"fairway": {
"pathWidth": 2.0,
"handleLength": 3.0,
"tightSplines": false,
"secondarySurface": "rough",
"secondaryWidth": 3.5
},
"rough": {
"pathWidth": 1.7,
"handleLength": 3.0,
"tightSplines": false,
"secondarySurface": "",
"secondaryWidth": 0.0
},
"heavyrough": {
"pathWidth": 1.7,
"handleLength": 3.0,
"tightSplines": false,
"secondarySurface": "",
"secondaryWidth": 0.0
},
"cartpath": {
"pathWidth": 2.0,
"handleLength": 4.0,
"tightSplines": false,
"secondarySurface": "",
"secondaryWidth": 0.0
},
"walkingpath": {
"pathWidth": 1.7,
"handleLength": 2.0,
"tightSplines": false,
"secondarySurface": "",
"secondaryWidth": 0.0
},
"pond": {
"pathWidth": 0.01,
"handleLength": 0.2,
"tightSplines": true,
"secondarySurface": "",
"secondaryWidth": 0.0
}
}

This seems to work well when you useChad's program to make Lidar courses with OSM.


Just to clear any possible problem - I said above to put the splines.json program into your course file when it should be in your courses FOLDER. Sorry about that

If people want an easy method to do this with LiDAR / OSM then here’s how;

Map out the green spline on OSM and then when you do the fairway spline make sure to go around the green and share the points exactly with fairway and green, this will align your spline points perfectly once ported into the game giving you perfect transition.

You will also get a collar of light rough now seamless around the green as part of the fairway.

If you find that bits of fairway are showing round the perimeter of the green just nudge the green spline wider into the settings to 1.8 or 1.9 or make the fairway spline .1 narrower.

If people wants a photo tutorial of this I’m happy to share

This heavily depends on how the green shapes were mapped out compared to their actual size. On Black Creek I mapped the greens much farther inside than I normally do, as I desire very straight edges without waviness in the path. Most of the time, what you described is what I do, and then to better match fairway width with actual (I still spline my fairways a bit inside, always) I usually end up reducing path width to around 2.4-2.5 or so. It varies per hole but I haven't had any issues getting fairway width to +/-1.5yd of actual measured width on google earth.

I also learned from Black Rock that, since the game can move fairway splines around a bit accuracy-wise, that the light rough around greens is not as consistent as one might expect it to be without tedious assuring that fairway points stay a consistent distance inside the green fringe. That is why I came up with that 'differential method.' I will try this setting 'tightsplines' to true in chadgolf's adjustment file, however.

I still think having a little ribbon of fairway around greens if not edited looks far cleaner than abrupt 90 degree transitions do.
