[Qgis-user] 3D View incl. Buildings from DGM and Shapefile in SketchUp

[Simon Haufe]

Dear QGIS-User,

it is my aim to get a 3D-View in Google SketchUp.
The data basis consists of a DGM with > 100.000 points of elevation 
(ASCII-File with x,y,z) and a shapefile with the contours of some 
buildings. The buildings should be located on top of the Elevation-View 
in SketchUp.


Do you have any suggestions how I can do this with QGIS and/or GrassGIS 
oder another OpenSource Software?


Kind regards,
Simon Haufe

[Qgis-user] Where is the invert color ramp in QGIS 3

[C Hamilton]

In QGIS 2 when you apply a pseudocolor color ramp to a DEM there was an
Invert color ramp check box. I cannot find it in QGIS 3.0.3. Am I missing
something or has it been dropped? I use that feature all the time.

Thanks,

Calvin

Re: [Qgis-user] QGIS3 Zonal Stat in raster Analysis fail count

[Mensio Federico]

But the raster and vector have the same CRS.
The raster is 20X20m, the grid 100mX100m and the two files have the same
origin.

 Can you share sample data and the parameters you use?

Re: [Qgis-user] QGIS3 Zonal Stat in raster Analysis fail count

[Mensio Federico]

Ok. I prepared the data. Because they are very large i post here the
wetransfer link (available up to 06/12)  https://wetransfer.com/dow
nloads/7639472c353a5c3c151972d694fa148d20180605134054/6594c2
39a24a7e346bb3bd5b0a38533220180605134054/21473e
All vector data are stored in a Postgres DB, exported to a csv (with header
comma delimited) and they are:
grid.csv, the grid zone where i need to calculate the number of pixel
contained in the raster file uf.tif. All pixel have vale of 1
uf_qgis2.csv the result of zonal statistics using qgis 2.18.15 that is
correct
uf_qgis3.csv the result of zonal statistics using qgis 3.0.3 that is not
correct

If you compare the uf_count or uf_sum fields of the two files you can see
difference

thanks in advance for explain and eventually solve the problem

[Qgis-user] Deleting a part of a geotiff file.

[Xero]

Hello I would like to delete a part (ereatic generated data) of a geotiff
file I've already imported in a raster layer.
Anyone know if it is possible and if yes how to do it.
Cheers ;)

Hi,
You could create and save a style based on the attributes.

I am surprised that Qgis can use the styles found in the dxf.

[Qgis-user] QGIS Processing Modeler : Raster Calculator output issues

[Juliette Ortet]

I currently work with rasters and I'd like to create a QGIS plugin. To do so, I 
use the QGIS Processing Modeler. I need to use the raster calculator.
When I use the raster calculator in the QGIS toolbar (out of the Processing 
Modeler), I get the good results for my formula. But when I use the raster 
calculator with the same formula in the QGIS Processing Modeler, there are some 
issues with the output raster:
1. on QGIS 3.0 (Girona): the output raster only contains "no data" values.
2. on QGIS 2.18 (Las Palmas): the process is done, but there is no output 
raster.
3. on QGIS 2.6 (Brighton): the process is done, but the output raster isn't 
properly generated and can't be loaded and saved.
Any ideas to face this issues ? Thanks in advance :-)
Juliette

[Qgis-user] Importing Layers from .dxf to .kml

[Pedro Amaro (Infratec)]

Hello.



I am trying to create a .kml file with the information contained in a .dxf
file.



I already can upload the .dxf file to QGIS and keep the dxf's layers'
information. Also, QGIS presents the .dxf drawing with its original colours.



I also can create the corresponding .kml file. The problem is that this .kml
file presents every element with one colour only. I can select manually
different colours for different .dxf's layers, but usually I have dozens of
layers and doing so manually takes a really long time. Is there anyway I can
create the .kml file keeping the .dxf's colours, as QGIS presents? I do not
know if it is useful, but I have an attribute that has the RGB colour.



Thanks!

[Qgis-user] QGIS 3.0 processing modeler : resampling raster to a higher resolution

[Juliette Ortet]

Hi everyone,
I work with Sentinel-2 images. I use Band 02, Band 03, Band 04, Band 08 and 
Band 11. Unfortunately, Band 11's resolution is only 20m, whereas the others is 
10m. I'd like to change de Band 11's resolution to 20m.
I work with QGIS 3.0 (Girona).
I tried to use RasterCalculator while keeping the same projection and defining 
the output file resolution at 10m. It doesn't seem to work, because after that 
I use RasterCalculator one more time with a formula including Band 11 and the 
other Bands and the output raster is empty.
I also tried to use SAGA Resampling tool, but the output can't be loaded by 
QGIS, disappear and seems to be lost forever.
I finally tried to use GRASS r.resample tool, but again the output can't be 
loaded.
At the end of the day, I wanted to export the model as a python script to 
create some new function to resample my image, but you can't do so on QGIS 3.0.
So I tryed to rebuild the same model on QGIS 2.18.20 (Las Palmas), but the 
process fails when I use WRAP (reproject) tool (however, it seems to work on 
QGIS 3.0).
Any ideas to achieve my goal ? Thanks in advance :-)
