Get original XYZ coordinates of input pointcloud

[mikepianka]

Hi - I am trying to read in a pointcloud that is using state plane coordinates with XYZ values around 351000, 1621000, 1300. After reading the file, cloud.points has XYZ values around -62, -38, -11. To add the original XYZ coordinates as new columns on the dataframe I tried the code snippet shown below, but something doesn't seem right because I notice there are z_world values that are less than cloud.las_header.z_min. I'm trying to bring the points into a Geopandas GeoDataframe so I can try making a convex hull of the points. Any help is appreciated. Thanks!

cloud = PyntCloud.from_file(las)

points = cloud.points

x_offset = cloud.las_header.x_offset
y_offset = cloud.las_header.y_offset
z_offset = cloud.las_header.z_offset

points["x_world"] = points.x + x_offset
points["y_world"] = points.x + y_offset
points["z_world"] = points.x + z_offset

points.head()

I noticed my issue was actually that for each "world" column I was adding points.x to the offset instead of the correct points value. Things are working fine now. I would just have deleted the discussion but I can't seem to.
