Re: [Qgis-user] On-the-Fly Projections Versus Manual Re-projections

[Nicolas Cadieux]

Hi,
Indeed, in QGIS 3, on the fly is default. You can change that in the project 
properties by going to project/properties/CRS select No Projection.  It’s not 
exactly like turning off on the fly in QGIS 2 it does help when trying to 
trouble shoot projections or if you want to mesure distances in a Euclidian 
space.

Good call.
Nicolas

Thanks so much Nicolas---this is extremely helpful! Two more quick 
questions, and then I will stop pestering you! :-)


First, if I change my project back to 4326 now, will that cause any 
problems given that I have already loaded 12-15 layers into the project?
When In doubt, save the project before making a big change.  In this 
case, you can move back and forth without trouble.


Second, are there circumstances in which it would important to have 
the project set to a geographically-specific EPSG (and ensure that all 
the files are in that same EPSG)? For example, if you are using an 
elevation model to delineate a particular river basin or wanting to 
measure the acreage of intact forest in a county in the US, will your 
results be significantly different based on whether you have 
transitioned all of the files to the "local" EPSG? Basically, I am 
just trying to get a feel for when one needs to worry about changing 
the EPSG.


Your example is very good.  Let's add more info.  Imagine the following:

 * Raster DEM Elevation is in WGS84 Long/lat (epsg 4326) (a global
   Geographic CRS).  With this, you make a basin file.
 * County file is in WGS84/UTM ZONE 20N (in metres) (epsg 32620) (local
   CRS)
 * Your spatial query: What county is in what basin?

If you create the basin in 4326 you need to know exactly how the spatial 
query will be made by the software.  If there is no reprojection, files 
will not align and the query does not work. If the software (or plugin) 
does a reprojection, you need to know what algorithm will be used and 
trust it.  Results can change according to the method used.  See the 
documentation with the plugins or contact the person responsible.


The other way is to do all the work yourself so you don't have to trust 
a coder. You could


 * Reproject the Raster from 4326 to 32620 then make the vector basin
   file or
 * Make the vector basin file in 4326 then reproject that in 32620. 
   This is probably better and will lead to better results as
   reprojecting a raster does change the raster a lot depending on the
   algorithm chosen (nearest neighbour, bilinear, cubic...) (
   https://www.gdal.org/gdalwarp.html)

Basically, you need to evaluate the impact of the reprojection on each 
data source and make the best decision... or trust that the software is 
doing a good job.  If your research depends on it, you better do it 
yourself.

Hi,

Unless you have a specific problem with the project being in a
certain CRS like 3125, there is no need to change that in the
project.  If Project on the fly is working with every layer, all
is good.  If your project is in 3125, have one file in 3125 and 10
in 4326, then you need to know that QGIS is reprojecting 10 files
to 3125.  That takes time especially if you have very big .shp
files or rasters.  In that case, it may be faster to change the
project in 4326 to speed rendering up.  Occasionally,  you will
have plugins that do not work unless all the files and the project
have the same CRS.  Keep that in mind.

Apart from that, it comes down to the look and feel of the map and
even that can now be changed in printing layout (since Qgis 3 I
think).

Cheers!

  Well, Nicolas gave you an answer tha may apply to your case.

  By the the side, it seems that Qgis3 does on the fly re-projection
automagically, it seems that there is no way to turn this off.  Even so,
when you look to layer properties it will state what thw original
projection was.   That is, if your layer was produced in EPSG 4326 and is
loaded in a EPSG 3125 project, Qgis3 will re-project it to the project
reference system, but keep informing you the original projection of the
layer.

  In this case you most probably will have to do nothing.

Re: [Qgis-user] Can't find Python

[Clifford Snow]

Daniele,
Thanks - pip is likely the cause. I use pip often but have been ignoring
where pip installs. In the future I will be sure to use pip(3) --user.  Now
I have to go through and reinstall a bunch of python modules.:-)

Snap may also contribute to the problem. Unfortunately Fedora doesn't
always have the apps needed or are badly out of date. For example I use
Nextcloud. Nextcloud version is currently 14.03. Fedora, last I checked, is
still on version 10.

Thanks for your help,
Clifford

no, python3-qgis isn't a requirement of QGIS, it's an optional dependency
(like GRASS). It's true that QGIS without the python support is missing
several extended features, but the main capabilities of QGIS do not depend
on Python. This is well described both on the official documentation and on

The problem is here */usr/local/*lib64: it looks like you are not using the
standard PyQt5 distribution available via the official Fedora RPMs
(otherwise QtCore.so would be under /usr/lib64 and *NOT* /usr/*local*/lib64).
It's probable that the QtCore version offered by
/usr/local/lib64/python3.6/site-packages/PyQt5/QtCore.so doesn't match the
one which QGIS is compiled against, which is 5.10:

$ rpm -qf /usr/lib64/python3.6/site-packages/PyQt5/QtCore.so
python3-qt5-base-5.10.1-4.fc28.x86_64

You must make sure that QGIS is using the libraries provided by official
Feodra RPMs or at least (even if still dangerous) versions of libraries are
matching the same API level.
Generally speaking overriding Python system libraries installed via RPMs is
a bad idea. You should use virtualenvs instead (or the user prefix at least,
like via pip --user) and leave the system clean.

Hi,

These are two very different projections. I would load a base map from 
Quickmap services plugin to see if files are being loaded correctly.  If 
the files are in 4326, and are loaded in 4326, then all is good if they 
are well georeferenced (use the Quickmap base map to make sure).  If 
files don't have a CRS, they may been incorrectly loaded if you have the 
"use project CRS" or "Use a default CRS" in the options/CRS/CRS for new 
layers menu.


If a file is in 4326 but incorrectly loaded in another projection, you 
need to correct the CRS not reproject it with GDAL WARP.    Simply right 
click on the layer in the layers panel, change the CRS (Set CRS/set 
layer CRS) (Qgis 3x) and save the file under a new name.  That should 
change the CRS and the file position on the map.  If you are still in 
the wrong place, you need to make some guess work.

I don't know why you're saying not having a working installer with GRASS, the 
last few versions have been working as far as I know, I haven't heard of any 
problems recently.  Yes, this one was broken, now there is a new version to 
download that is fixed (and shouold stay fixed in the future, for this specific 
problem).  Really, a polite "GRASS is not working, it's doing this, or not 
doing that" on the mailing list, or better a bug report, is all that's needed.

You might want to check out Missing Maps, missingmaps.org. I've been
involved with a number of efforts to map areas for just your purpose. MM
uses the HOT tasking manager tools [1] to break the work up into manageable
size and then opens it up so everyone can contribute. It just takes someone
willing to create a task and help spread the word. Andhra Pradesh is a
large state so I would suggest starting off with more vulnerable areas,
like coastal areas, first.

I did check OSM - overpass reported more than 200Mb of buildings - that's
before the query crashed from the size.

QGIS TimeManager supports WMS-T but it's a bit of a hack:

If you have development skills and are interested in improving support,

The issue should have been fixed now, changes backported to GS 2.14.x and

Re: [Qgis-user] Question

[Nicolas Cadieux]

Hi,

Others have responded.  I will only add that Google Earth uses OSM data and 
data from local governments, like NRCan in Canada.  You can always vectorize 
the data from Google but all you will get for Google is a pretty picture.  I 
would contact local governments for data if it exits.  You can always look at 
what is available from satellite imagery from the various space agencies.  I 
imagine you are looking for roads?  You can also use data from openlayer plugin 
or better, the  quickmap plugin.  That plugin has additional providers that you 
can add in the plugin properties.

Re: [Qgis-user] Question

[Phil Wyatt]

Hi Mayank,

 

What sort of information were you hoping to gain from Google? The underlying 
imagery that can be used to digitise features into Open Street Map is often as 
up to date as Google. Maybe you could contact local OSM or Humanitarian teams 
and support adding further information to Open Street Map.

 

If you want to look at Google imagery in QGIS then you can do so from the Quick 
Map Services plugin.

 

Cheers - Phil

Thank you for replying.

I was working on a detailed map development of a certain state (Andhra Pradesh)

 in India. This would be useful in disaster management and would be accessible 
by all. 

Openstreetmap does not provide detailed features of the place that is why 
wanted to check if someone has found a way to use google information.

Any leads in this regards are appreciated
