LiDAR issues/tool issues

[bongabaz]

qq. i am trying to run a lidar for a course in scotland, which is split over 2 laz files. running into an error:



Processing: NT07SE_2PPM_LAS_PHASE2.laz

Problem looking up epsg with prj2epsg.org and/or spatialreference.org, try running the tool later.

prj2epsg.org may be down, using backup for force_epsg

Overwriting projection with EPSG:27700

Unit in use is 0.9999999946369966

Proj4 : pyproj.Proj('+units=m +init=epsg:27700 ', preserve_units=True)

Processing: NT17SW_2PPM_LAS_PHASE2.laz

Proj4 : pyproj.Proj('+units=m +init=epsg:27700 ', preserve_units=True)

Could not load NT17SW_2PPM_LAS_PHASE2.laz Please report this issue.

it runs through 1 file ok but doesnt include the full course.

thoughts?

The website prj2epsg.org that the Tool uses is no longer available. You will have to "Force EPSG" in order to get the file to be used. Chad's latest version of the tool recognizes that prj2epsg.org is gone, and I think it looks for an EPSG somewhere else in the .las file, but it often does not find one.

thanks. downloaded Chad's  latest version, but still having trouble with the second LAZ file. redownloading. maybe using wrong EPSG for Scotland. using 27700 for UK
