[Qgis-user] Swap atributes

[Christoph Schumacher Planungsbüro Schumacher]

Hello group!

Is there an easy way to swap attributes from two objects on one layer?  
I didnt found a easy tool to do that.

Christoph

Hi Christoph,

the latest version of the DigitizingTools extension [1] contains a 
function to exchange the geometry between two selected features in the 
active edit layer.

Add this function was in my plans for the last QGIS Hackmeeting, but

Dear QGIS users and devs,

we did a progress with our new generation of GIS.lab Web client built on top
of QGIS Server. There where a few WFS service problems, which caused switch to
QGIS master and slight delay on schedule, but I really hope that until the end
of the next week we would be able to show something (including proposal of
mobile friendly UI, WFS filtering and other features).

GitHub repository has been moved [1].

BTW, is there anybody going to attend FOSSDEM at the end of the month ?

thank you for your message. What do I have to do to "hire a developer or

I'm new to QGIS and the development process, that's why I have to ask.

Re: [Qgis-user] how to save output of Topology checker?

[Luigi Pirelli]

you can start asking in the qgis-developer list :)

in that list you can find different cases of successful crowdfunded
funcionalities (Lutra, QGISCH, Radim,...)

btw strange case of the life... a person, just today, asked me similar
stuffs about where to invest public funds if in the Topology Checker
plugin or in the Geometry Checker plugin.

what do you mind?

Hi Philip,

I just tested the plugin both in 2.8, 2.12 and current master, and it is
working fine. Both in epsg:4326 as in a projected crs.

are you working with a strange crs maybe? Or is the layer you are
working in other then the crs of your project?
Maybe OTF en/diabled?

If all fails, you could try to contact the plugin author via the issue
tracker of the plugin:

http://plugins.qgis.org/plugins/rectovalDigit/

But as said, with me the plugin just works.

Richard Duivenvoorde

Hi Richard,
of course I did. But it doesn´t work: The alignment in the section "Data

I want to realize curved labels with specific alignment.

Thanks for further inputs.

Hi Nikolai,

did you have a look into the label properties?

a LOT of options I see there.

you need something else?

[Qgis-user] Problem with decimal places in coordinates

[Giacomo Minotti]

Good morning friends
I have a big problem.

When I import in qgis ambient a .csv file with known coordinates at a given
number of decimal places, and I create a SHP file the decimal places of my
coordinates change.

For example: in .csv file a coordinate input type is X 15.67; when I save
as .shp file, the coordinate becomes 15.669 ... (with 15 decimal places
and not 2).

It there any methot to mantain the same number of decimal places?
Is it possible to choose the number of decimal places when I save a .csv
file to .shp file?

Thanks
Domenico

How about using the "SIFT" method to find GCPs and then run i.rectify
to bring them together?

Or, mosaik with SIFT, then georeferencing the resulting mosaik map to
a modern orthophoto mosaik.

Or, run each tile through i.ortho.rectify for a full approach.

And then deal with the rail lines...

Just an idea,
Markus

[Qgis-user] Problema cifre decimali

[Giacomo Minotti]

Buongiorno a tutti



volevo chiedere se qualcuno può aiutarmi.



mi capita questa cosa, quando importo su Qgis  un CSV di punti con
coordinate note e con un determinato numero di cifre decimali, e genero un
SHP i decimali delle mie coordinate cambiano.



Ad esempio: ho sul csv una coordinata in ingresso tipo X 15.67, quando la
importo e genero l'shp, diventa 15.669...(di default mi riporta 15
cifre decimali)



C'è un modo per mantenere in ingresso il numero dei decimali.



E poi si può impostare il numero dei decimali (di default mi riporta 15
cifre decimali) delle coordinate in uscita quando esporto un CSV da un SHP.


Grazie
Giacomo

Re: [Qgis-user] best way to download Large datasets from OSM

[Clifford Snow]

I just found this [1] morning. Looks like a good way to get started. I does
require installing PostGIS. The instructions are for Linux but Boundless
geo has installation pages for OS X and Windows. I have no experience on
Windows. The advantage of using a database back end is being able to run
queries for just the data needed. That should allow QGIS to run without a
30GB load.

You can share your QGIS styles with the repository for others to use.

Re: [Qgis-user] best way to download Large datasets from OSM

[Ramon Andiñach]

There's a nice blog entry by Anita about this sort of thing. 
A guide to GoogleMaps-like maps with OSM in QGIS. 

OSM has some really large index numbers now which means you probably need to 
bump it into some sort of DB for it to be useful.

Re: [Qgis-user] Styles and PostgreSQL

[Bernhard Ströbl]

Hi,

the relation is public.layer_styles. The problem is the xml fields. I 
once noted for myself to

SET XML OPTION DOCUMENT;
prior to importing the dump. Didn't do it for a while so I am not sure 
if it works.
Another option is to dump layer_styles as plain SQL and then import it 
into the other machine.

Hi,

I use QGIS 2.12.2 and PostgreSQL 9.5 + PostGIS 2.1.8 (Windows x64).

I´ve saved styles using the option 'Save in database (postgres)'.

It works fine when I add a table to another project with 'Add to
canvas', it brings the style associated with the table.

But when I backup a schema and restore it in another machine I lose the
styles.

Where are stored the styles? Can I move a schema or a database to
another machine without losing the styles?

Thanks a lot for your answer!

Greetings,
Roberto.

Perhaps I'm being dense but none of those questions apply to a user land

Re: [Qgis-user] best way to download Large datasets from OSM

I just found this [1] morning. Looks like a good way to get started. I does
require installing PostGIS. The instructions are for Linux but Boundless
geo has installation pages for OS X and Windows. I have no experience on
Windows. The advantage of using a database back end is being able to run
queries for just the data needed. That should allow QGIS to run without a
30GB load.



I suggest to import OpenStreetmap data into Postgis using the standard 
osm2pgsql. For Windows, the latest builds are linked here:

Update:

Since you are looking for a small bit of the whole OpenStreetmap data, 
it is worth filtering the data before feeding it into the database. 
osmfilter and osmosis are useful tools to do that on raw OSM data.

Actually - just a warning - that plugin leaks memory badly. Do a few
edits and eventually QGIS will grind to a halt.

[Qgis-user] Styles and PostgreSQL

[Roberto Jesús Dip]

Hi,

I use QGIS 2.12.2 and PostgreSQL 9.5 + PostGIS 2.1.8 (Windows x64).

I´ve saved styles using the option 'Save in database (postgres)'.

It works fine when I add a table to another project with 'Add to canvas',
it brings the style associated with the table.

But when I backup a schema and restore it in another machine I lose the
styles.

Where are stored the styles? Can I move a schema or a database to another
machine without losing the styles?

Thanks a lot for your answer!

Greetings,
Roberto.

Re: [Qgis-user] Problem with decimal places in coordinates

[Nicolas Cadieux]

Hi,
There are 2 problems.  The first is that not all number can bit 
represented on a base 2 representation (we normally use base 10 for 
finances and banking).   Wiki that and you will find it.  It's normal 
for things to change a bit.  The second problem is the number of 
decimals in the field.  When you create a shp file, you can specify the 
length of the decimal place.  If it's there, you can probably use the 
field calculator to create a new field with your specified length and 
copy the data from 1 field to the other.   (It may be too much trouble 
for a non significant error if that is the case.) There may be a plugin 
that may change number of decimal.  (If you do, backup your original). I 
may help if you specify the type of collumn you are importing in the 
csv.  This may help.

Re: [Qgis-user] control position of line labels

[Joris Hintjens]

I remember a discussion here, about year ago about redering labels along lines. 
It was a requested feature the. 

I advise a search in the archives.

[Qgis-user] best way to download Large datasets from OSM

[Joris Hintjens]

Hello,
Ive been spending the past few hours trying to find out what is the best way to 
download large chunks of OSM data.

I have no understanding of Databases nor of programming, so I am limited to 
predefined tools, algorithms and/or plugins. 

I want t create a map of all the (navigable) rivers and canals in Europe.
I downloaded the osm.bpf of Europe (30 Gig) and when I try to start a query, 
QGIS freezes.

Downloading from overpass only the rivers with Quickest plugin) , gives me 
timeout error (even after increasing the timeout parameter) 

any other suggesting welcome.

Joris
