Bonjour de France, just a small view of the result with LIDAR data made on the 200km coastline of my sector

Verry cool.

What's your workflow?

Why you don't delete the land datas?

Are the land datas as LIDAR and the depth datas as sonar datas together and was it a raster or a vector data set?

The free data is in the form of an X, Y, Z (200giga) file made for monitoring erosion, and preventing the invasion of the land by the sea during high tides and storms, from where the file sea and land, just to realize a limit to keep only the part that interests me.

Hi Nitro
Can you tell me what "projected" parameters you have set.
I loaded the .xyz files of Litto 3D but I did not find the parameter 'Lambert-93', so I am not aligned with the map of Finistère.
If you can help me
thanks in advance
Phil

Hi Nitro
Sorry, I did not look well.
I found the parameter "Projected" = NationalGrids, RGF1993Lambert 93`
But put Latitude = 2, Longitude = 1
I get closer but there is a gap, I find myself in the land not far. There must be a parameter to align the set.
