I'm trying to create a raster .tif from a ground classified point cloud file using PDAL (https://pdal.io/en/latest/).
I installed PDAL following the Quickstart instructions provided in the PDAL documentation (https://pdal.io/en/latest/quickstart.html). I successfully created a classified point cloud file. I want to create a raster digital elevation model (DEM) using writer.gdal. I have GDAL installed on conda using the following command: conda install -c conda-forge gdal
I wrote a pipeline using Visual Source Code following this tutorial (https://www.youtube.com/watch?v=tvL25Y7O-Dw).
{
"pipeline":[
"ground_north.laz",
{
"type":"writer.gdal",
"filename":"north_dem.tif",
"gdaldriver":"GTiff",
"output_type":"all",
"resolution":"1.0"
}
]
}
When I call the pipeline using this command 'pdal pipeline to_raster.json' I get the following error message:
PDAL: Couldn't create filter stage of type 'writer.gdal'.
You probably have a version of PDAL that didn't come with a plugin
you're trying to load. Please see the FAQ at https://pdal.io/faq
How can I fix this?
I'm very new to using conda, and I apologize if this isn't clear. I'd appreciate any and all help/tips/advice!
You have a small typo in your type, it should read writers.gdal
not writer.gdal
.
A sample pipeline is below.
{
"pipeline": [
{
"filename": "ground_north.laz",
"type": "readers.las",
},
{
"type":"writers.gdal",
"filename":"north_dem.tif",
"gdaldriver":"GTiff",
"output_type":"all",
"resolution":"1.0"
}
]
}
If you're trying to isolate specific classes for your raster you'll also need a filter in your pipeline something like:
{
"type": "filters.range",
"limits": "Classification[2:2]"
},
