Re: [Qgis-user] QGIS 2.99 crashing on 17.10 with project properties menu

[Patrick Dunford]

it's reported as a known issue

So I filed a bug report (17662) - but I can't actually say that this is a bug.
I did two tests and both ended up with QGIS 2.99 crashing. So I think it's a
bug. I built a VM off kubuntu and it crashed - this machine has had 2.18 on
it.

If I start qgis and click on the project properties in the lower right it
crashes.
If I start project properties from the file menu it doesn't crash until I click
on the CRS menu.

Any suggestions on what I can do to better describe the issue? I don't see any
chatter on this so I'm thinking it must be my machine. I'm a bit stuck on how
to proceed.

Re: [Qgis-user] LiDAR Data in QGIS

[Randal Hale]

I'm dealing with a different issue here in Tennessee - We have the original 
files except they are locked in zlas (ESRI Proprietary Format) BUT - I can get 
it out of zlas so I can have fun with the LAS files. 

Good news is - LAS was a thing in 2003 
(https://www.asprs.org/committee-general/laser-las-file-format-exchange-activities.html)
 so you might be able to 
get those OR at least a CSV file. 

You might have to go back to the vendor. They probably have them but might 
take some work to pry the files out of them. 2003 might be a life time ago for 
many. 

Good luck though! and take a look at GRASS and PDAL. I feed the LIDAR data 
into GRASS and pull the returns out or reprocess it. I'm not that great at 
doing it but learning.

Re: [Qgis-user] LiDAR Data in QGIS

[Randal Hale]

I've only been watching this thread when I remember - so My apologies. 

If I go back to the original thread - if these are in ADF I believe that's 
ESRI's GRID Format. Which means they are what they are and you can't do much 
with them. They have only the last return (or if I remember correctly returns 
classed 2,8, etc). 

If you have zlas, las, or laz - I would suggest GRASS for processing: https://
grasswiki.osgeo.org/wiki/LIDAR

If you don't have any of the las/laz formats - you might want to do some 
research and see if they were delivered with the LIDAR dataset you have or if 
they weren't request them. They may be sitting somewhere on a shelf/forgotten 
folder on a server. You can do a lot more with the original LIDAR files like 
pull tree heights or possibly rebuild the surface (be it dsm/dtm/dem etc).

Re: [Qgis-user] LiDAR Data in QGIS

[Tyler Veinot]

All;
But if I convert the DEM or DSM to geotiff I still wont get back the hit
order or the classification values will I? I will just have the data I have
as processed in a different format. What I really need is the original
LiDAR datasets if I am understanding this correctly.
As for DTM, DSM, and DEM, The province my municipality is in has decided
that; DTM is a surface model which includes surface features + ground hits
+ breaklines. A DEM is ground hits, and a DSM as is the surface + features
without added breaklines. I have found definitions online to support both
view points on the matter; just an FYI my text books agree with you on the
matter. I blame AutoCAD/CADD users for the discrepancies because, in my
experience according to the EIT's and other CADD users, a DTM is all of the
above and a DSM and DEM doesn't exist lol.
Thanks for the help on this;
Tyler

Re: [Qgis-user] LiDAR Data in QGIS

[Richard McDonnell]

Morning Tyler.
Nick is quite right. The files you have (ADF) are either DTM's or DSM's. 
They are processed datasets.
To fix the GRASS, SAGA issue, you can use GDAL to convert them to 
GeoTiff, using the gdal_translate, which can be found in the Processing 
toolbox and will do it for a few using batch (Note Point one below).

The other option would be to use the Script below to convert ADF to GeoTiff.

*@echo off SET startpath=%1 FOR /R %startpath% %%f IN (w001001.adf) do 
(call :translate "%%f") pause GOTO :eof :translate SET var=%~dp1 ECHO 
Translating %var%hdr.adf to %var:~0,-1%.tif gdal_translate -co 
"NUM_THREADS=ALL_CPUS" -co "TILED=YES" -co "COMPRESS=LZW" %var%hdr.adf 
%var:~0,-1%.tif*


The tool/script works in the following way.

1. *ADF Image names are the containing folder name*
2. You must run this Batch in the Root folder for your ADFs (one level
   up from the ADF files)
3. Paste/save the batch in the root folder
4. Open an instance of OSGeo4W Shell or its Linux counterpart navigate
   to the root folder and run the script by typing */adf2tiff.bat/*
5. It will start to write the Tiff files into the root folder.

Hope this helps, or goes some way to helping.
Regards

Richard.
