[Qgis-user] Export GeoPDF Mac

2020-05-15 Thread Adam Sneath 
Hello there. I want to export a georeferenced PDF from my QGIS project, and I 
am unable to tick the box as I need GDAL 3.0. However, my colleague is using 
windows (I am using a mac) and he is able to export as a GeoPDF without any 
issue, despite him not having GDAL. I hoped you could help me towards a 
solution. Thanks___

[QGIS-it-user] Richiesta tiles da indirizzo webgis

2020-05-15 Thread athanatos 
Buongiorno a tutti,ho una domanda riguardo a QGIS. In questo periodo sto realizzando un file con vari strati WMS riferiti alla mia regione (Valle d'Aosta) di cui esiste un webgis reperibile al seguente collegamentohttps://mappe.regione.vda.it/pub/geoCartoSCT/Non viene fornito l'indirizzo WMS dell'ortofoto che si vede sullo sfondo pertanto vorrei provare una strada alternativa. Ho aperto il webgis in Chrome, ho premuto la combinazione di tasti CTRL+MAIUSC+I (ispeziona) e sono andato nella sezione Network. Da qui si vede che le varie tiles hanno questa forma (ne allego una a caso)https://mappe.regione.vda.it/INVA/config/config.ashx?https://mappe.regione.vda.it/cache/rest/services/Foundation/Mista/MapServer/tile/1/146/163Ho provato ad inserire il link in QGIShttps://mappe.regione.vda.it/INVA/config/config.ashx?https://mappe.regione.vda.it/cache/rest/services/Foundation/Mista/MapServer/WMTS/?request=getcapabilitiese riesco ad ottenere un layer... ma non vedo nulla.Secondo voi è possibile modificare questa stringa (magari con {z}{x}{y}) in modo da poter vedere il layer dell'ortofoto in QGIS? Pongo questo quesito perché vorrei sovrapporre l'ortofoto al layer del catasto. L'ortofoto é fondamentale per non commettere errori (le foto satellitari non sono rettificate).Ringraziandovi in anticipo,Saluti___

Ciao

hai provato qui

http://metadati.partout.it/geoportal/catalog/search/resource/details.page?uuid=r_vda%3A03413-META%3A20170519%3A105500


nella scheda
Distribuzione dei dati
[image: Apri/Chiudi sezione] Accesso on-line
NB: da verificare se funziona!!

Normalmente un servizio WMS, se fornito, lo trovi nella scheda dei metadati
(quando no pubblicato in chiaro)

Se non è fornito in chiaro, spesso, non è fruibile...

Re: [Qgis-user] Map contest: mapping Pi for the 3.14 splash screen

2020-05-15 Thread Andreas Neumann 

Hi Richard,

Nice thoughts - and really nice photo of the ice with penguins!

I could envisage a very nice splash screen with a map of antarctica with 
a nice azimuthal (stereographic or gnomonic) projection, the islands of 
Pi and a pair of compasses on top of it, similar to this 
https://www.mandalana.de/media/images/zirkel-kreis-zeichenvorlage-zeichnen-vorlage.jpg 
but with a map and a marker of the Pi Islands in Antarctica.

As you may have noticed, the next release version will be 3.14 and

Usually our versions are named for community meeting locations and the

For 3.14 we are looking for creative maps that capture the essence of Pi.

All submissions will receive an honorable mention in the release blog post.

The winner will see their map on the release splash screen and banner on

Wow, if you go to Google Maps on that position they show you a Photo of
a Hari Das:

THAT is worth a splashscreen (if he is ok...):

Re: [Qgis-user] Viewshed From Specific Elevation?

2020-05-15 Thread Kirk Schmidt 

Chris:

Super. In retrospect, the negative observer height should come back with 
a null result as you cannot see much if you are standing in a well.


You could run a buffer of 2 m around every observation point and 
recalculate your raster DSM values to a set elevation (ie 10m) and 
calculate your observation elevation by  subtracting 10 m from your 
actual observation elevation.  That way, your observation height will be 
modeled correctly.


Have fun

I’ve done what you described – select a point away from the edge and 
manually adjust the observer height. This does work.


I also tested negative observer height. If it is surrounded, the 
viewshed simply shows nothing (neighboring pixels only).


However, I’m going to be doing 100+ points over multiple locations. 
Ideally, when I setup a viewshed point (including elevation), I can 
just run an analysis from that location and ignore the first 2m or so. 
I think manipulating every point will be cumbersome.


Thank you, Chris

You could try converting the first lidar returns to a raster layer and 
using a negative elevation observer value or select point that is one 
or 3 pixels away from the edge of the roof.  I am not sure if the 
negative observer height will work but it may.  If you need to remove 
obstructions, you can create a mask and recalculate the elevations if 
the obsructions below the observer height and rerun the viewshed.

Subject: [Qgis-user] Viewshed From Specific Elevation?

I am attempting to test viewsheds from multiple heights below the 
roofline of particular buildings. I have been identifying viewing 
positions from directly from LiDAR data, but I cannot find a way to 
use absolute values for elevation.  The build-in visibility analysis 
seems to always use the raster elevation value plus the relative 
observer height.


I would like to use an absolute Z value, and have some immediate zone 
that is ignored (i.e., ignore the first 2m of obstructions) so that a 
viewpoint that might be lower than the raster elevation value can get 
outside of a building.


Is there a plugin or alternative visibility analysis tool that can do 
this? I was able to get it to work in Manifold Viewer, but I would 
like to keep the workflow within QGIS if possible.


Thank you, Chris
