How to create a real Canada course with Lidar data

[David Shen]

Hello Everyone，
I am very new player on TGC 2019, and start to create real course by Chad's Tool. The two most important parts for a real course are Lidar data and layout. The Layout part is no problem with using the Open Street Map. But the most challenge part is how to get the lidar data that Chad's tool can recognize.

After 2 days research, I have got the lidar data from Ontario Land Information Website. Everyone can also get that lidar data for free from the following link. https://geohub.lio.gov.on.ca/dataset...9.847%2C46.309


I can open and see the land elevation files from QGIS software(an open source software). I want to build my home course Cardinal Red Crest, the following is that area.


Every thing looks good so far. But finally, I realized the Elevation Data file what I downloaded are in DEM raster formats (.img/.tiff with.xml) not the raw LiDAR point clouds format (.las/.laz) that Chad's tool supported. So the next thing is to convert DEM raster format to point clouds format, but it is a very difficult thing. After another two days research, I can convert the .tiff files to .las files with SAGA GIS latest version(an open source software). Please check the following screenshot.

It looks good again. 😃
But when I copy the .las file to my course building folder and run Chad's tool, it report an error that it needs a metadata file(.xml) for the .las file. Then I manually create a metadata file (.xml). Then the next error is "Sorry, this lidar data is not classified and I can't support it right now. Ask for help on the forum or your lidar provider if they have a classified version."

This is the point I went so far. I need help. Is there anyone know what I did wrong? what is the correct way to build a real Canada course with Lidar data in DEM raster format？

Any idea how to remove or move OOB area form the map? found the solution... space bar key

Do you guys have Lidar for Barrie? Looking for the Barrie Golf +CC and National Pines.

Yo, I'm an up-and-coming designer who thus far has only really done British Columbian courses.
I used this thread to find Lidar for Ontario and I've found Lidar for B.C here.

I was wondering if there was somewhere I could find a consistent source of Lidar across the other areas of Canada.


My courses:
Canada
Victoria golf club
Meadow Gardens golf course
Big Sky Golf Club
Stuart Lake Golf Club
Coldstream golf course
Radium Hot springs: Springs course
108 golf resort.

Myron have you done any Lidar golf courses in Alberta. I was hoping someone may have done D"Darcy Ranch Golf Course in Okotoks. Is there Lidar available for this area?

[RVPar]

Sorry proper course name D'Arcy Ranch.

I have the same problem with the metadata error. I would like to build a course in Germany. The course is already created in openstreetmap. How can I use my .laz lidar files there now? Do I have to use qgis for this? If so, how should I do that?

[jpotas]

I published two courses in Germany, I was able to donwload Lidar for free for one of them. The other one required a purchase. My client made the purchase and then emaled the Lidar to me to create the course. Both were actually from the governemnt though,

The two courses are Levin's Erfurt and Levin's Altenholf.

I downloaded the laser data here.

https://geodaten.bayern.de/opengeodata/OpenDataDetail.html?pn=laserdaten

But I don't get a separate metadata file there. Do I need this or is it a course creation or can it also be done with the data that is available there?

Thank you very much for your help.

That looks like you should b able to get a LAZ file or files. Which is what you need. You just have to find teh area that you need, download it, and put the files into whatever folder you are using to create the course.

[LinderA]

Which files are required for this to work? I tried it exactly like that but then got the error with the metadata.

[jpotas]

Are you using Chad's Tool? Did you enter an EPSG?

[LinderA]

Yes, I use the Chad Tool. Where can I get the EPSG data for my coordinates?

[jpotas]

try looking it up on a google search for your area, or look at www.EPSG.io, or even try opening the LAZ file with notepad or wrod. It is often listed in the file. Better yet, ask the source where you downloaded it.Or send the LAZ to me at jpotas67@gmail.com and I can extract it for you.

I sent you an email. Thank you for your help.

[jpotas]

Check your email. I ran the course for you and emailed you the course file. Happy designing now!!
