were converted to LAS-format files through Neuralog. The LAS files, included in Tables 1 and 2, were created from scanned Tagged Image File Format (TIFF) files (Fig. 3) that were in turn converted to an LAS format (text file) via Neuralog. Once transformed to an LAS format, the file was accessible in an LAS viewer (e.g., GeoGraphix Prizm) where ...You may use las2ogr (las utility application), but your GDAL libraries must be built with libLAS. Convert las file to txt using las2txt (las utility application) and use ogr2ogr converting CSV file to DXF; Convert las file to txt using las2txt (las utility application) and load it to QGIS as a delimited text file and save as DXFSo, is there a better way, more efficient, more pythonesque way of injecting the .las file points (from laspy) to the GeoPandas dataframe without passing through a numpy array? No, and I'm not sure why you think this is the least efficient way to go. laspy is underneath the covers making a memoryview to the data and the Numpy array is a wrapper ...

ArcGIS Pro can use the LAS files directly, but often these come as a collection of adjacent files. To work with a collection of LAS files you create a LAS dataset which stores reference to one or more LAS files on disk, as well as to additional surface features.The las file contains a mixture of LWD measurements and two images. As las files are flat and don't support arrays, LWD image data is often delivered as individual sectors. The second file we will load is the survey, this allows us to understand the deviation and azimuth of the wellbore and is useful for calculating accurate formation dips. ...
