Rasterize Empty cells interpolate

[TahmidTowsifAhmed]

I have tried rasterizing a las from UI where I selected Empty cells Fill with as interpolate. I have attached the image.

But when I tried to run it from the command line, I could not find the command. I used the following command.
"C:\\Program Files\\CloudCompare\\CloudCompare.exe", "-SILENT", "-O", "-GLOBAL_SHIFT", "AUTO", las_file_path, "-RASTERIZE", "-GRID_STEP", grid_step_str, "-OUTPUT_MESH", "-OUTPUT_RASTER_RGB", "-SAVE_MESHES"

Can anyone help me with the command?

See the '-EMPTY_FILL INTERP' option (https://www.cloudcompare.org/doc/wiki/i ... _line_mode)

And if you can, use the latest 2.13.beta version (there's a small bug with the 'max edge length' parameter in previous versions).

Thanks Daniel.
It worked fine.
However, the area around the raster becomes black. Is there a way to solve this?

In the latest versions you can use 'Kriging' interpolation instead of Delaunay. You can use the '-EMPTY_FILL KRIGING' sub-option.

I've just updated the wiki documentation (I forgot to do it before!).

Hi Daniel,

There is a new problem I have encountered recently and I want wondering if you can help me with it.

For a .las file, I have generated .tif files from CloudCompare, while a friend of mine did it from another resource. He is getting way too much better resolution here.

The tiff file from cloud compare is the one on the left.

I was wondering if you have any suggestion on how can I improve the resolution.

Hi,

Hard to say without the data in hand, but:
- you don't seem to use any interpolation?
- have you tried to reduce the step size? (you'll probably need to interpolate while doing that ;)

i have tried the following command

command = ["C:\\Program Files\\CloudCompare\\CloudCompare.exe", "-SILENT", "-O", "-GLOBAL_SHIFT", "AUTO", las_file_path, "-RASTERIZE", "-GRID_STEP", "0.007", "-EMPTY_FILL", "KRIGING", "-OUTPUT_MESH", "-OUTPUT_RASTER_RGB", "-SAVE_MESHES"]

here i have tried with different grid size but still did not get any significant improvement.

It doesn't seem the Kriging was applied... What's does the log tells?

And have you tried the same thing in the GUI version?
