Re: [Qgis-user] [QGIS-Developer] web based spatial MIS/Dashboard

Hi Janneke,

Did you take a look at Lizmap? Here is a good example of a map and a 
dashboard reacting to selections:

Cheers from FR :)

Hi Rosa,

thanks for the quick response - I am also not sure exactly what my 
question is, so all answers are probably helpful. I am now having a 
look at streamlit and seeing if that helps me get a better picture. 
It's definitely interesting!


cheers from Tz :-)

Hi, Janneke
I am, not sure whether I understood your question correctly.
For a web app with dashboard you may need a data server + app server  
+ front-end

There are several libraries that you can use to create what you want.
I have use D3 and openlayers for the front-end (interactive select + 
doing something)

Porgresql as DB server and QGIS server (Geoserver is a common option)
https://streamlit.io/ is gaining traction and something you may want 
to look at it.


Hope this helps,
Cheers from NL.

Subject: [QGIS-Developer] web based spatial MIS/Dashboard

Dear QGIS developers and users,

In my work as a freelance GIS consultant I work with QGIS as much as 
possible and try to convince clients that it will address all their 
GIS needs despite not having to pay a license fee for it (and no, it 
is not user unfriendly).


More and more, in addition to wanting 'a GIS system', there are 
requests for a web based management information system which shows 
both maps and a dashboard with selected KPIs, and where selecting a 
feature on the map will update the graphs and charts in the 
dashboard. So far, I have not been able to find out if this is 
possible using Open Source software, what it would require in terms 
of setting it up/configuring/additional development. I assume it is 
technically possible to develop it.


Does anyone have experience with this? How did you set it up? Any 
examples I could have a look at? I guess strictly speaking it is not 
a QGIS question, but seeing that some other proprietary GIS software 
vendors are offering web dashboard functionality 'out of the box' it 
does get associated with the GIS software procured.


Is there a demand for it (from my limited view - yes)? Are there 
thoughts about developing such functionality more 'out of the box'
within the QGIS community? What would such development require? My 
impression is that there is more (very tentative) willingness from 
donors to consider contributing to Open Source software development 
as part of development projects, but it may mean that it would need 
to be written into tender proposals with indicative figures for the 
required funding.


I have a limited understanding of what is out there (I've just 
dabbled (so far unsuccesfully) with chartbrew and grafana the past 
few days to see how dashboard creation works) so I am not sure what 
are the right questions to ask. I realise my questions are still 
rather broad. I have some time at hand so I would be available to do 
more research and become more specific if there is an interest in 
this topic.


Looking forward to your ideas!
Janneke

Dear QGIS Users

On Friday, 30th September 2022 we will be holding our monthly QGIS 
Open Day! What is a QGIS Open Day you may be wondering to yourself? It 
is an initiative to replace the wonderful community meetups we used to 
hold every six months when times were different. Like our in-person 
meetings, the event is organised on the principle of self-organisation 
and community participation.


Programme

  * Session 1: Model Design for Watershed Delineation YouTube Link
, Jitsi Link

  * Session 2: Book review session on QGIS for Hydrological
Applications - Second Edition and Discover QGIS 3.x - Second
Edition YouTube Link , Jitsi Link

  * Session 3: Set up your own vector tile server to use with QGIS
YouTube Link ,Jitsi Link


Where to watch

Please see the event wiki page at QOD-September-2022 Wiki

Re: [Qgis-user] qqis project to a web platform

2022-06-14 Thread Nicolas Boisteault via Qgis-user 

Hi Alexandru,

You can test QGIS Web Client 2, gw3suite, Lizmap to just name a few...

Hi all!

I have a few projects that I need to upload on the internet. As I am 
completely new to webgis platforms, I would appreciate few hints and 
directions (from your experience) where should I start looking to get 
a better understanding on how it works.

In simple words, what i am looking for:

  * is to have a qgis project uploaded 'somewhere' and it looks
exactly the same as i designed it (without too much hassle), it is
also easily editable (in terms of changing an attribute, polygon,
line, color, etc.)
  * i expect it to be able to show me a range on attributes when i
click on a feature
  * with tools like measuring distances and surfaces
  * and maybe to print something from it quickly

I would appreciate any opensource (better) or proprietary software 
that would help me. Or maybe where is the best place to store our data 
on a webserver so it is easy interchangeable with a local computer. I 
would also appreciate any help on how to setup a webserver.


Thank you in advance!
Best,
Alexandru

Hi,

I suggest you to try Docker with docker-composer.

Here is an example :

Re: [Qgis-user] What happened to "Update SQL Layer"?

Thanks for the tip!

To answer my own question, I had a little discussion with the 
developers here: 
https://github.com/qgis/QGIS/pull/45801#issuecomment-1065101963 and 
learned that the previous behaviour involved a silent (and 
irreversible) conversion of an PostGIS layer to a query layer. Now you 
have to explicitly create a query layer either using the DB manager or 
the browser.
