Re: [Qgis-user] QGIS in the commercial world
Dear Iain, Yes, QGIS has an entity: QGIS.ORG is the worldwide association of QGIS users and developers. QGIS.ORG is constituted as a Swiss ‘association’ (https://qgis.org/en/site/getinvolved/governance/charter.html) but it is not a registered charity. To help support QGIS, organizations are invited to become sustaining members of QGIS.ORG. The details of our sustaining membership program are described in: https://qgis.org/en/site/getinvolved/governance/sustaining_members/sustaining_members.html You can also see who's already supporting QGIS: https://qgis.org/en/site/about/sustaining_members.html Regards, Anita On 15.04.2020 02:13, i...@jcis.net.au wrote: Andreas wrote /It was also good to see that 103 out of 1691 respondents represented an organization with >100 users.

Re: [Qgis-user] Refresh Layer at Interval not working
I've created a minimal script which generates a random point, more or less in The Netherlands..: https://duif.net/cgi-bin/gj.py If you load that script as a vector layer /Protocol/GeoJSON you will see one point in The Netherlands. Upon hitting F5 (menu: View/Refresh), you will see the dot moving as it is requesting the data everytime.. For what I know this worked for all datasources? Not sure if this is what you try to achieve, but that is also possible with python (though I do not have it with me here...)

Re: [QGIS-it-user] Analisi di visibilità
poiché fai l'analisi su un dtm e non su dsm, puoi aggiungere un offset, cioè un'altezza che aggiungi al valore di quota della cella dtm senza alterare il raster. quindi una persona di 1.75 m che si guarda intorno stando in una cella avente 320 m slm di quota porta ad un'analisi in cui l'osservatore è a 321.75 m slm. inoltre, dato che un punto vede ed è a sua volta visto, aggiungi l'offset all'altezza delle turbine (ad esempio 15 m). dato che ti occupi di turbine ti consiglio questo lavoro [1]: tre autori (annalisisa minelli, pierluigi de rosa e ivan marchesini) frequentano questa lista e quindi ti possono spiegare meglio.

Più che altro, vorrei ben capire dove è opportuno inserire l'altezza massima della turbina e perchè? In un video ho visto che il campo dell'altezza della turbina è inserito nella voce "field value for observer height", ma vorrei capire il perchè.

Ciao, sto effettuando un'analisi di visibilità di un parco eolico tramite la visibility analysis di qgis. Ho creato uno shapefile per definire nome e altezza massima delle turbine. Devo creare adesso i "viewpoints" e vorrei per favore da voi conferma sui parametri che utilizzo. Il mio obiettivo è verificare la visibilità delle turbine ad una distanza di 10 km. [image: image.png] A parte i dati certi che sono lo shape delle turbine, il raggio dell'analisi e il dem da utilizzare, vorrei capire se è corretto inserire come "Observer height meters" 1,75 m cioè l'altezza media dell'uomo che osserva entro un raggio di 10 km, e come "target height meters" l'altezza della turbina. Così facendo, l'output del sistema è la visibilità di un osservatore di 1,75 m posto a 10 km che "osserva" una turbina di h m? Inoltre, se io avessi creato uno shapefile, invece di inserire l'altezza della turbina in "target height meters", ottengo lo stesso risultato se in "target height meters" lascio 0 e in "field value for target height" inserisco la colonna dello shape che riporta le altezze?

Re: [Qgis-user] Pavement defects Identification
Hi, My experienced in the field of road surface and condition survey is, that it is a very tough task to create a robust procedure. There are so many outliers and special situations. Because of this, many companies evaluate the raster images manually anymore. A state of the art method would be deep learning using a convolutional neural network. The Technical University Ilmenau (Germany) has a project group working on this topic with very good results. If you have just a small area with big, easy detectable defects, than it could be possible using the semi automatic classification plugin mentioned before.

Re: [Qgis-user] Refresh Layer at Interval not working
Hi Ayyala, Since the option is in the tab called "Render" I think it will only re-render the layer and not reload the data. I tried this: - create 3 points in a geojson layer - set a 2 sec refresh interval on it - open the geojson file in a text editor and add an extra point - save geojson The extra point should show up within 2 seconds in qgis but it does not. Even after panning or zooming it does not show up. I think it would if I used a postgis layer or a shp-file? Could this be dependent on the data format? If you need an example of a refreshed layer, you can type "hackfests" in the Coordinate input at the bottom. It will show you the hackfest locations with "moving" markers. @other users: Does QGIS have an option to reload data for a layer? In the GUI, similar to the "Update Extents" button?

Re: [Qgis-user] Pavement defects Identification
Hi, It would be possible, though it would depend on the raster and the bands (Red, Green, Blue, NIR etc..)you have available. It could be possible to use raster Classification to map these features, though I believe you would have quite a lot of false positives, due to shadowing, surface finish changes..etc.. If you where to look at it I would recommend the Semi-Automatic Classification Plugin https://fromgistors.blogspot.com/p/semi-automatic-classification-plugin.html It can be installed through the Plugin installer. Please also see the Link below, it may be of further interest. https://link.springer.com/article/10.1007/s12544-015-0156-6 As you may see from the above, it does suggest that you supplement the Raster Imagery with additional datasets, which should help in the detection of road defects and the overall accuracy of your results.

Re: [Qgis-user] LTR usage survey
Hi Anita, Thanks for sharing these stats. I also had a look at the question labeled "In an ideal world, how often would you prefer to have new LTR versions?" 431 out of 1691 (25%) would like to have a longer time span than 1 year for LT versions If we filter this by organization size, this number increases (as expected) with the size of the organization. In the category 11-100 users, the number increases to 29%, in the category >100 users, it is already at 40% who would like to see a longer life time of the LT version. Probably if we had another category with even larger organizations, that value would go beyond 50% ;-) It was also good to see that 103 out of 1691 respondents represented an organization with >100 users. I expected a lower number in this category and was quite surprised.
