Where a lot of vertical cliffs (benches) were classified as building

Hey @coumbsek :wave: thanks for the PR! We can't merge this as-is. Make sure to use the correct LAS ASPRS codes when classifying the point cloud? See the README for instructions.

Hi, The dataset is a cloud generated by ODM that I edit, as per the recommandations. I change some 6 to 2 but it's the only edit I made. So there are points with 1, 2 and 3.

pierotofy commented 1 year ago

The classification codes of the contributed file are in the range 33-35 (which do not match the required codes).

Maybe it's a problem with the export in CloudCompare, does it work if the file is exported in LAZ 1.4 instead of 1.2? (If that's the case, we need to update the README).

Also, sorry for all the confusion! We're still ironing out the quirks of the contribution process :pray:

coumbsek commented 1 year ago

That is really really strange. I was not sure so I re-download the file from github to be sure. I check with CloudCompare and have the good values... BUT then I realised that I re-install it just before to get rid off my alpha version (after reading the instructions on the repo) just to re-install another alpha version... I am dumb :( With the stable release I have the same values as you. I will change all the values and re-upload it later (next week I think).

Don't worry it's how things progress, we are paving the way for the next, one stone at a time
