[Qgis-user] Log Messages Panel is missing, how do I revert or undock it from the python console?

[Thayer Young]

I have lost my Log Messages Panel in my default User Profile, when I switch to 
another profile I can open the Log Messages Panel by clicking on the button in 
the bottom right hand corner with the three dots in a callout bubble, or by 
selecting View:Panels:Log Messages.  In my default profile the button 
flashes the screen, but nothing after that. Selecting in the View menu opens a 
blank gray window in the last place where the panel was docked.  I have 
been using the Python Console a lot and I think I may have docked the Python 
Console into the Log Messages Concole. Is there a way to undo this?  
    One thought I have is to copy files from the QGIS/QGIS3/profiles folder of 
a profile that is working, but I am not sure which one to choose. Would this be 
in the qgis.db file? Thanks for any advice.

Re: [Qgis-user] PostGIS connections time out in Database Manager

[Cliff Patterson]

Hi Larry,

Both those settings are set to default. I create/delete many PostGIS
connections, so I suspect at this point that something in the profile data
folder is buggy. My plan is to delete the profile folder, reinstall from
scratch, and see if the problem persists.

Will report back.

Re: [Qgis-user] Creating Rectangle Around Central Point

[gam17]

Hi Mike,
   you can use QAD plugin, run POLYGON command to draw a regular
polygon.
The command will ask the following parameters:

Enter number of sides <4>: 4
Specify center of polygon or [Edge]: 
Enter an option [Inscribed in circle/Circumscribed about circle/Area]
: Circumscribed about circle
Specify the circle radius <100>: 100

The radius of the circle will correspond to the square dimension.

if the center of the polygon is specified in a coordinate reference
system different from the current one:

- if the coordinate reference system is projected:
enter x,y (SRID). For example 1491621.64817, 4915622.63154 (EPSG:3003)
is a point with coordinate X=1491621.64817 and Y=4915622.63154 in the
projected coordinate reference system EPSG:3003

- if the coordinate reference system is geographic:
enter latitude, longitude (SRID). For example 44º 24' 48N/ 08º 50' 15E
(EPSG:4326) is a point with latitude 44 degrees 24 minutes 48 seconds
and longitude 6 degrees 50 minutes 15 seconds in the geographic
coordinate reference system EPSG:4326.

Re: [Qgis-user] Where is the read me for MacOS installer referred to install 3.1.12 securely?

[Ramon Andinach]

It’s a frequently asked question.

QGIS hasn’t been officially checked by Apple (notarised), so macOS puts up the 
error.

If you trust it, then you can add an exemption by right clicking 
(control-click) on the QGIS.app and select open.



I think the readme comment relates to the alternate build, when you really do 
need to read the readme.

[Qgis-user] Where is the read me for MacOS installer referred to install 3.1.12 securely?

[Headington Heritage]

Hi

I have just downloaded QGIS, MAC OS 3.12 and it fails to verify – “App can’t be 
opened because Apple can’t check it for Malicious Software”

The installation page states:


Mac Installer Packages for macOS El Capitan (10.11) and newer.

Installation instructions are in the Read Me on the disk image.

But there are about 20 Readmes , and going through these I cannot see one the 
describes how to do this, reluctant to just use generic methods to bypass the 
security.

Also, it took quite a while to get into the dmg image and open it to view 
contents.

Any help as to the safest way to install would appreciated!



Thanks

Re: [Qgis-user] Creating Rectangle Around Central Point

[Christine]

Dear Mike,

have you already tried the tool 'Rectangles, Ovals, Diamonds' of the Vector
geometry group in the QGIS Geoprocessing ?

The tool requires the input of points (you have one: your GPS coordinate).
You may choose 'rectangle' as the desired shape and the width and height of
the rectangle with 1 km. 

Should work. Problems may occur perhaps, if you are trying to apply the tool
with a non-projected coordinate system. GPS devices often return only
geographic coordinates. Maybe you should reproject your central point before
applying the tool and ensure you have set a projected coordinate system with
Meters as a measure unit in your QGIS project.  

Regards and good luck,
Christine

[Qgis-user] new plugin Closest Points

[Christoph Jung]

Hello everybody,

Some months ago, I asked you about the possibilities in QGIS to calculate the 
closest points from one layer to another. It is a very easy task in PostGIS, 
but the discussion figured out, that QGIS has no tool/plugin or something else 
to get the closest point geometries on an easy way. It is only possible to 
create a join between two layers via the field calculator or the function „join 
attributes by nearest“. Because of this, I created a new plugin (after a long 
time with a low priority for this project ^^) called Closest Points. It creates 
a point layer with the closest points using the PyQGIS functions nearestPoint() 
and distance(). For me this tool is very helpful, maybe Someone of you could 
need it too :)

Sincerely,
Christoph

[Qgis-user] Creating Rectangle Around Central Point

[Michael Jabot]

Good Morning

I am trying to create a square 1km X 1km around a central point that has
GPS coordinates.

I have tried every suggestion and plugin suggested but am struggling.

This is intended to be used with students as part of their science field
work once I figure out what I am doing wrong.

Thank you in advance for your help.

Re: [Qgis-user] QGIS 3.10: Dimensioning with on-board equipment

[Richard McDonnell]

Hi,
All you need to do is modify the label. It uses an expression round( $length ) 
|| ' m' if you change this to round(100*( $length) ) || ' cm'
Hope this helps

Hallo,

I have successfully implemented Paolo 
Cavallini‘s proposal for dimensioning:

https://geoobserver.wordpress.com/2018/02/05/qgis-bemassung-mit-bordmitteln/#comments

But I have not found out how to improve the accuracy of dimensioning from 
meters to centimeters.
I would be very grateful for a hint.

Best regards,

Hartmut

During certain operations, the main window will automatically resize itself to
