Re: [Qgis-user] Small towns and villages of France

He. Hamish, EuroGlobalMap is a free source from the collaborating EU mapping 
agencies, it has a layer BuiltupP (for points) that goes down to rather small 
villages (<2000 in. or so). See screenshot attached.

Hi,
Please could someone recommend which of the components of Natural Earth will 
give me the smallest populated places in France (e.g villages) or an 
alternative copyright free source for France to use with qgis?
Many thanks for your help.

Re: [Qgis-user] QGIS in the commercial world

2020-04-16 Thread b.j.kob...@utwente.nl 
Just a side-note: I filled in the survey and said I work in an organization of 
>100 employees. That is because my university has almost 800 staff. But only a 
max of 50 or so use QGIS regularly. On the other hand we have 3200 students of 
which also a proportion uses it...

In other words, don't make assumptions on actual QGIS users based on that 
survey question!

Hi Michael,

Yes, I interpret it is the nr of employees using (Q)GIS on a regular basis 
within an organization. And it is based on self-declaration and there is no 
control about the numbers whatsoever.

We have quite a nr of municipalities that support us on the "small" level as 
sustaining member.

All is based on a voluntary contribution anyway and you are not required to be 
a member in order to use QGIS.

Greetings,

Andreas

Sustaining membership works  out a bit steep for us if you follow the guideline 
– about 10 times what we currently pay for commercial software (Manifold).
Is it reasonable to interpret number of employees as GIS users rather than 
total employees?
I see my local council is on there as small, and I’m sure they have more than 
10 employees.

Obviously no limits apply if we go with donations without membership.

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

Anita

Hi Hamish,

Yes, copyright has to be taken into account for any data sources you use in 
your QGIS project.

Esp. base maps. Note, f.e. that you cannot use Google Maps as a background 
layer for your new map. The terms of Google Maps disallow to create any new 
maps based on their data, if it isn't using the Google Maps API and keys.

You can use OpenStreetMap as a base map, but they also have a copyright: you 
have to mention that you use their data, if you want to use it.

And you are not allowed to derive any data from Google Maps base data.

Text and images, as you say, also have copyright.

Andreas

Hi Hamish,

Your assumptions are right. As the map author, when you are creating new maps 
in QGIS, you are the copyright owner of your map.

However, as Paolo pointed out, if you load data from various sources, you'd 
have to first check the copyright conditions of the data you use to create your 
maps.

Good morning,

I am an historian looking to bring to life a work for publication illustrated 
by annotated physical and cultural maps inspired by examples seen from QGIS 
training videos. As a stumbling beginner I have already invested many hours 
trying to master the basics. However, before I invest many more hours and 
finessing maps I need to know urgently if I will have to pay copyright 
permission to use my maps in a publication. Am I being naive in thinking maps 
created become my own property and copyright just applies if I attempted to 
develop software using elements found through QGIS? The latter is my impression 
scrolling through terms and conditions. I.e maps produced are free and become 
my copyright in a publication?

Thank you in anticipation of your time.

Best wishes

Re: [Qgis-user] QGIS 3 - Joins

2019-10-18 Thread b.j.kob...@utwente.nl 
Another way would be to leave the joining up to Postgres, i.e. create a VIEW 
with the Join and load that view as a layer in QGIS...

Dear list,

I have a postgres layer that is connected to other postgres lookup tables 
via joins. QGIS does not take these joins into account when copying a layer (to 
another project) or when creating style or layer files. This is really annoying 
if you have to rebuild the joins by hand over and over again. Am I doing 
something wrong? In the dialog window "Edit Vector Join" I see no further ways. 
I only activated the option "Cache join layer in virtual memory". 

Any hint is appreciated, thanks. 
I'm using QGIS LTR 3.4.12

Re: [Qgis-user] Upsampling TIN

2019-10-04 Thread b.j.kob...@utwente.nl 
?? a point in between what? A TIN is a set of triangles, where each corner 
represents an X,Y,Z point in space (on a surface usually). So where do you nwat 
to have and extra vertex...? Sounds like you are not wanting aq TIN in the end, 
but something else...

Hi,
I am more interested to have a point in between rather than the triangles, 
basically interpolate the data twice, to have an extra vertex between the 
existing one.
