[Qgis-user] Drill hole section with QGIS 3

[jwellman]

To help elaborate the mechanics involved for using drill information I will try 
to cover the data and steps.
 
1)  The data consists of at least 3 files. 
 
The first file (Collar) contains 1) the name of the drill hole (Primary Key) 
(surface perforation, bore hole, etc.), 2) the drill hole surface coordinates 
(x,y,z), and 3)  the drill hole length. 
 
The second file (Orientation) contains 1) drill hole (Primary Key), 2)  Azimuth 
(0-360), 3) Inclination (Usually a number from 0 to -90), and 3) the depth, 
i.e. the distance from the start of the drillhole for that particular set of 
measurements.
 
The third file (Attributes) contains 1) the drill hole (Primary Key), 2) A FROM 
or START distance value for the start of the attributes,  3) A TO or END 
distance value for the end of the attributes, and 4) as many as needed columns 
of Continuous or Classified values.
 
 
Often a dialog controls how the drill hole attributes are displayed.
 
 
The creation of 'Sections' entails creating a constrained 3d 'window' into the 
data with it's own set of contents, and dimensions on all axis.  Then the 
script would automate the output of the view such that for an area of interest, 
there would/would not be overlap between views, and there would also be a Plan 
View strip at the top.  Achieving this while displaying real world coordinates 
is preferred.
 
 
>From what I gleaned about the new 3d capabilities, the idea of draping a 
>registered raster onto a DEM or set of 3d contour (poly) lines appears to be 
>the primary functionality sought.  As it is the early stage, I assume the 
>wish-list que is longer than the accomplished que.
 
What does it take to setup a 'working group' to explore how to achieve 
something like this.  My reaction is to utilize python as much as possible.
 
I don't know QGIS so well yet.   I am proficient in some of the other 
commercial GIS packages.

Re: [Qgis-user] Drill hole section with QGIS 3

[Bob and Deb]

In the past, I've was hoping to make a QGIS plugin to do Liquefaction
Analysis .  This analysis
uses a borehole database, ground motion grids, and historical high ground
water grids.  What prevented me from doing it was that QGIS Relations can
not work with composite keys .  So, I
hope that any work on getting QGIS to work with boreholes would address
this problem.

This is also of interest to the archaeological community, in terms of 3-D 
representations of excavations, soil strata, location of artifacts, etc. GRASS 
has Voxel capabilities that allow this, but additional tools like this would be 
of interest to archaeologists.

Hi Calvin,

In geology, we use a set of drill holes into the ground to interpret the space 
in the earth between them. Depending on what the geologist is interested in, we 
might be plotting the location of an aquifer, or a gold seam, an oil reservoir 
or some other feature. Note here, that I’m deliberately picking things that 
have length, breath and depth, so just interpolating a surface is not the same 
thing.

So, things that you might want to be able to do include:
 display attributes of the drill hole on a string representing the drill hole 
(or drill trace) in real 3D space.
 Create slices (sections) of these drill traces (so depth is the right and left 
side), with windows of included data on either side of the slice.
 Draw polygons snapped to the drill trace to link areas with similar features 
between holes.
 Build a mesh/wireframe model that links the polygons together
 Get a volume of said model
 Create a voxel model of an attribute/s distribution within the mesh.

This is probably a slightly economic geology skewed view, but hopefully I’ve 
left enough geo-jargon out that it’s understandable[1]

Depends on how complex you want to be. A well known GIS package in my neck of 
the woods trumpets the ability to do the slice and dice and section bit, but 
really it’s making up non-earth plans and dressing them up as having proper 
depth (a section). For some people that seems enough.
But - that sort of approach makes it really difficult if what you’d really like 
to do is show just the bits of the drill holes with say, gold grades greater 
that 20g/t - leaving any other result as transparent - and spin it slowly 
around in 3D so that you can get a sense of the go/d’s distribution pattern. 
This last one is much more complex and only possible if you’re working in a 
truly 3D environment.

Hope that makes some sort of sense. Feel free to ask for clarification.

Ramon.

There is active interest in developing a drill hole plugin for QGIS3 now that 
3D is more fully supported.  I also work with drill holes and have been running 
them in QGIS fairly easily in plan view where I just calculate traces to a plan 
view (either in a spreadsheet or using code) and apply theme patterns based on 
the attributes I kept with the segments.  This has worked reasonable well with 
grade and lithology which are two of the main things you want to see.

Cross sections have been harder, but those are still “maps” in non-Earth

either a spreadsheet or by code.  This is not as easy to work with as plan view 
so I am very interested in seeing the developing interest in getting a drill

Hi Calvin,

In geology, we use a set of drill holes into the ground to interpret the space 
in the earth between them. Depending on what the geologist is interested in, we 
might be plotting the location of an aquifer, or a gold seam, an oil reservoir 
or some other feature. Note here, that I’m deliberately picking things that 
have length, breath and depth, so just interpolating a surface is not the same 
thing.

So, things that you might want to be able to do include:
 display attributes of the drill hole on a string representing the drill hole 
(or drill trace) in real 3D space.
 Create slices (sections) of these drill traces (so depth is the right and left 
side), with windows of included data on either side of the slice.
 Draw polygons snapped to the drill trace to link areas with similar features 
between holes.
 Build a mesh/wireframe model that links the polygons together
 Get a volume of said model
 Create a voxel model of an attribute/s distribution within the mesh.

This is probably a slightly economic geology skewed view, but hopefully I’ve 
left enough geo-jargon out that it’s understandable[1]

Re: [Qgis-user] Drill hole section with QGIS 3

[Stefan Giese (WhereGroup)]

The gis representation of a drill hole is normaly a point with some 
stratigraphic or lithological information of the underground behind it 
(a 1:n relation, 1 drill = n strata). In qgis2 there was the midvatten 
plugin which does such drill hole sections (see attached image).


hope this makes the drill hole thing a bit more clear...;-)

Pardon my ignorance on the matter, but what does a drill hole

There is active interest in developing a drill hole plugin for QGIS3
now that 3D is more fully supported.  I also work with drill holes
and have been running them in QGIS fairly easily in plan view where
I just calculate traces to a plan view (either in a spreadsheet or
using code) and apply theme patterns based on the attributes I kept
with the segments.  This has worked reasonable well with grade and
lithology which are two of the main things you want to see.

Cross sections have been harder, but those are still “maps” in
non-Earth coordinates.  Again I’ve tended to build those with
projections to a plane in either a spreadsheet or by code.  This is
not as easy to work with as plan view so I am very interested in
seeing the developing interest in getting a drill hole section
plugin for QGIS.  That will really finalize QGIS as the logical
choice for geological exploration work.

I’ve cc’ed the others I know using QGIS so I hope you can be
included in the list of interested users.

Pardon my ignorance on the matter, but what does a drill hole capability
mean? Is it simply making a hole in a polygon or is it much more complex.

Re: [QGIS-it-user] Comandi GDAL in QGIS 3.0

[Tony75]

Ciao
Se leggi sotto Ho inserito un post dove parlo proprio di questo problema.

Per curiosità hai problemi anche con grass e python?

[QGIS-it-user] QGIS3 - errore plugin Profile Tool

[Gabriela Osaci Costache]

 Ciao a tutti e tutte!
Su due portatili (Windows 10-64bit, QGIS 3 installato tramite osgeo4w 32 bit) 
ho lo stesso problema con il plugin Profile Tool usando un DEM tipo .tif : non 
è possibile disegnare la linea del profilo. Da qui l'errore python che 
incollo:2018-03-14T20:35:28 WARNING Traceback (most recent call last): File 
"C:/Users/Catalina/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\profiletool\tools\ptmaptool.py",
 line 78, in moved 
self.profiletool.rubberband.addPoint(QgsPoint(self.pointstoDraw[i][0],self.pointstoDraw[i][1]))
 TypeError: QgsRubberBand.addPoint(): argument 1 has unexpected type 'QgsPoint'

Profile Tool funziona alla grande con QGIS 2.18.16 e 2.18.17 con lo stesso DEM.
Grazie,Gabriela___

Re: [QGIS-it-user] Qgis3 - Problemi persistono - OSX

[Tony75]

ciao Salvatore
E se disinstallo tutto e uso  Homebrew    per
installare gdal?

O ripetere l'installazione con KyngChaos ? Seguito da:


echo 'export PATH=/Library/Frameworks/GDAL.framework/Programs:$PATH' >>
~/.bash_profile
source ~/.bash_profile

E dopo per verificare : gdalinfo --version


Mi restano anche altri due problemi sostanziali.
1)non trova Grass e mi dice che non esiste ( ma se apro il plug in mi fa
vedere le icone del programma, ossia riconosce l'interfaccia ma non lo
script. PS: Ho installato anche la versione di Grass 7 per mac esterna a
qgis e la devo testare)

2) gli errori di riconoscimento degli script Python.  Come posso verificare?

Grazie
