Re: [Qgis-user] Local Government for QGIS

[Milo van der Linden]

That is a great summary Falk!

I think the GIS community is lacking strategic marketeers and solid
branding. I personally tried to take that road once, thinking I was backed
by a solid group of open source professionals teamed up in a cooperation. I
was wrong. It is my opinion that the businessmodel where "one that does the
work gets paid" and "one that invests in relations does so on his own
account" needs tuning to put open source on the agenda of government
descision makers.

[Qgis-user] (no subject)

[Dominik Abrahám]

Hi,

I need to write QGIS script, which removes features with same value of
specific attribute - in output will be only features with first occurrence
of value. I know, how to check duplicity, but I don't know, how properly
create output from my script, when I need it to use in graphical modeler.

Also, what is the best way to get inputs into the script? I am beginer in
QGIS scripting, but I noticed that the basic scripts deal with inputs
differently than any downloaded user scripts (which follow this
documentation:
https://docs.qgis.org/2.6/en/docs/user_manual/processing/scripts.html).

Thanks for any advice.

Re: [Qgis-user] Local Government for QGIS

[Johanna Botman]

I, too, work for local government - in New South Wales (Australia).

We were an exclusively MapInfo shop until I came along. Not that I can
claim the move to QGIS ... but adding me to the staff meant that the
opportunity was there to explore open source software and how it would fit
into Council's IT and GIS.

There are hiccups, of course, but I find QGIS to be as robust as MapInfo,
sometimes better and sometimes not as good. I think, though, that this can
be said of any software comparisons.

Our reasons for changing were as the OP described - an unwillingness to be
locked into proprietary formats and expensive licensing agreements. We may
not be on QGIS forever, either. We are open minded enough to examine the
alternatives as they present themselves and take advantage of opportunities
as they arise.

While we are being asked to do more with less resources, we see this as the
most appropriate course at this time.

We have the support of consultants who know and understand QGIS and who are
partners with enterprises who fund and develop changes and improvements
with QGIS. And personally, I have found the help and support available
through this mail list to be invaluable. Through this mail list I have been
able to deal directly with the developer of a particular component of QGIS
and had it fixed in the nightly build.

Re: [Qgis-user] Local Government for QGIS

[Falk Huettmann]

Dear all,

thanks,
I find this is a very essential discussion to have, and with
QGIS, GDAL/R etc at its core and solution.

Much can be said, and should be said and changed,
but here a few points for a start:

-mapping relates to land, health and water management questions; many of
these are widely unresolved nor do many people really want it to be
resolved even.

-mapping is, and remains, a highly strategic and military topic.

-mapping affects economic growth and our neoliberal economy policy.
Software is directly embedded in that; now all driven by online developments
and its drivers.

-mapping and its tools and data are part of democracy.


Thus, a (tried) control of mapping, its data, and its tools, must come of
no big surprise. It's a heavily vested subject.
(one can add easily remote sensing perspectives in that discussion, and one
really should).

These things are not new, apply globally, and are part of any good
Geography textbook really.
I would go that far and put it as a major topic for Climate Change!

So I think the current status of GIS & governments and its inertia can
widely be derived from there.
We have much experience in that, world-wide (happy to share if somebody
wants to know; just ask...).

What about a good set of GIS and Remote Sensing ETHICS ?

Yes, I find it's time things change for the better.
Keep me posted please.

 Very best and thanks
 Falk Huettmann

Re: [Qgis-user] Field calculator - output layer CRS bug

[Nicolas Cadieux]

Hi, 
I don't use the field calculator in models but I would ask myself the following 
questions: Is there a projection file associated with the input .shp file?  Is 
that projection the same as the project or are you relying on projection on the 
fly?  If your using modules from an other program, does the program support 
that projection? 
You can also try to see if you can use another function instead or maybe you 
can add the projection afterwards. 
Hopefully, you will get an answer from someone who uses the field calculator 
the graphical modeler. 
Cheers!

Re: [Qgis-user] Local Government for QGIS

[James Keener]

Yeah. I used to intern in Pittsburgh, Pa's Dept of City Planning and there
were 3 people with Arc licenses that were always too busy to help the
neighborhood planners so we just emailed kml files around. (Much of my
summer was also (poorly) copying as-builts into Google Earth, because no
digital plans exist (or are owned by the city at any rate).  There is so
little that could make a huge improvement, and I want to help make those
improvements.

Like I said, I'm just starting up, but I am defiantly interested in putting
resources towards helping with the tooling and documentation.  Honestly,
from my opinion, the push back I've been getting is more that the people
who need these tools aren't technically inclined and don't have the
time/don't want to/don't think they can build up their GIS skills.

Beyond all of that, it's just insane that most of these municipalities
don't even own their data, the engineering firms they use have it all and
the municipalities never seem to want it, or would know what to do with it.

I'm trying to help on those two fronts.

Sorry if that was a bit long -- I'm excited!

Re: [Qgis-user] Local Government for QGIS

[James Keener]

I'm actually in the process of starting a company that sells GIS services
and consulting to municipalities.  I'm basing it on CartoDB for a web front
end, and then, unless they beg to use ESRI, QGIS for things like topology
and analysis.

I really do think there is room to break into the market, especially since
many municipalities are still using paper maps or just offload their GIS
needs to their default engineering firm.

I'm defiantly willing to help build software, models, documentation, &c
aimed around open source municipal GIS.

Re: [Qgis-user] Local Government for QGIS

[Randal Hale]

I've contemplated the same thing. I've been working on an openforestry 
template (which I'm failing to update on github) for that very reason 
(well two - to see if I could do it and because I want to provide an 
alternative).


It's doable - it's just finding a coalition of the willing to start 
piecing it together. ESRI does have a lock with all those models: small 
government, utilities, forestry. Everyone gets roped in and then they 
get stuck. My current shaking my head moment is the ESRI Parcel Fabric 
model. You get so deep into that one on just the conversion work you'll 
never get out of it cleanly (I assume - I've never tried).


QGIS is the desktop component to make that happen with a database 
backend (right now for me it's postgresql/postgis). Support is the next 
biggie - people want someone to call and yell at when it doesn't work.


My .02 cents,
Randy

Re: [Qgis-user] Opengeo (Geoserver) - QGIS 1:n relations

[Jonathan Moules]

Hi Pedro,
Generally speaking GeoServer doesn't do 1:n relationships.
At the base level, any GeoServer layer represents just one database table.

There are 3 exceptions:
1) Where GeoServer has been pointed to a View (see Alex's reply)
2) Where you have a layergroup. As their name suggests these contain many 
layers grouped together to appear as one.
3) If you're using an SQLView - 
http://docs.geoserver.org/stable/en/user/data/database/sqlview.html

I've not used the OpenGeo plugin so don't know what it's doing when it does the 
1:n relationship business.

Cheers,
Jonathan

Subject: [Qgis-user] Opengeo (Geoserver) - QGIS 1:n relations

Hi,

I'm using Opengeo plugin in QGIS top publish at Geoserver.
Have a problem that I don't know how to handle it.

At QGIS Project Properties established a relationship between two postgis 
tables (1:n).
So when  when I open an object editor got the information from the two tables. 
(just 1 table have a geometry column).

By submitting the project to the Geoserver (with OpenGeo plugin) it takes the 
individual layers, i.e.,  it lose the relationship between the tables.

Are you aware if there is a way to keep this 1:n relationship in Geoserver?


Thanks,
Pedro

Re: [Qgis-user] Issues with QGISConefor Plugin

[Ricardo Filipe Soares Garcia da]

Hi Niccolo

I am the author of the plugin. Thanks for trying it out and reporting this
problem. I'll investigate and fix it. In the meanwhile, I've opened an
issue in the plugin's bug tracker:

http://hub.qgis.org/issues/12936

I'll report back when the issue is fixed, which should happen until the end
of the week and I'll upload a new version of the plugin.

Best regards

Re: [Qgis-user] Template Composer

[Christine]

Hi Paolo,

a QGIS map composer template is not the same as an ArcGIS LYR-File. It saves
only the arrangement of your map composition elements, but no references to
the data of your map (as I remember). Actually that makes it easier to
transfer a certain layout (location and dimensions of map window, legend,
company or agency log etc.) to other projects with other data. 

To insert your data in an imported layout (*.qpt) you have to select the map
in the map composer, go to the 'item properties' tab and then in the section
of 'Extents' you have to click the button 'set to map canvas extent'. Your
data should be turn up in the (composer) map. Probably you need then to fit
scale and perhaps some other properties to your needs. 

Good luck, Christine

Here's a whole bunch of working examples. These can all be installed
from the download script in Processing now (under the R section).

I think you're missing a variable to return the answer with?
