[Qgis-user] geospatial PDF problem

2016-09-14 Thread Mac McKay

I would like to report an apparent bug that occurs when attempting to
create a geospatial PDF using Raster Translate in 2.16.2 (see below). My
search of the bug repository show that this problem may not yet be known.

I have requested a login id so that I may report it here:

Re: [Qgis-user] QField error data source is not valid

2016-09-14 Thread Reginald Carlier

Tyler,

What is a OGR dataset? I’m using a aereal photo raster and a shapefile in my 
project. There are no date fields in the shapefile.
The documentation gives a 404 error. Who is the developer of this app?
Where can I find his mail address so I can give a notice about the broken 
website.

Reginald;
I have been having problems with OGR datasets that have an assigned vertical 
datum. I suspect Matthias is correct but if that doesn't solve the issue and 
you are using a vertical datum that might be the issue.
On the documentation site http://www.qfield.org/ there was amention about some 
possible issues with OGR datasets but I get a 404 error now so I cannot 
reference the specific passage under the supported data formats.
Hope that helps some;
Tyler

Hi,

I’m testing QField. On my desktop I made a project with a shape point layer 
made to inventarise streetbenches.
Then I put this project in the storage folder (DCIM) of my android phone.
On my phone I open QField and I browse to the project and I open it.
In stead of a map I see only a point marker in QField.
The error message I see is: OGR Data source is invalid()
What am I doing wrong?
Also I could not find any documentation on QField. Any pointers in this 
direction?

Re: [Qgis-user] Organizing considering Dates

2016-09-14 Thread Tyler Veinot

Thank you, Tyler.
my table was built with the sampling dates wells, however, every time the
sampling was done ... was created a line with the same coordinate to update
the sampling.
I believe so is being very difficult to establish a filter.

Bia;
Not sure though how that would effect filtering, one of those things where
I would need to see the data and try some expressions.

I would almost break the table up into 2 tables; Sampling Dates and Well
Points. Then use a relationship between the 2 tables (well_id pk in wells
and a well_id fk in samples). That should make the data simpler, and
perhaps provide a better ability to organise and filter.

Re: [Qgis-user] Fail to commit changes to SQL database

I have seen similar behavior with SQL Server 2012, so I would be interested to 
hear from the user community as well. 

Johanna,
What version of SQL and is this SQL Spatial (ST Geometry)?

Thanks,

Peter,
Yes this is almost what I am looking for, 80% there... you appear to
be copying and pasting the whole xml, as opposed to reading a file
directly to postgres, which is what I need.
What I relay need to do is create a batch file for windows, which I can
drop into the folder with the xml's and batch insert. Unfortunately, my
knowledge of batching is not as good as I would like. The other option,
even more daunting, is to utilise Python to do the batching.
Thanks anyway for your help, its a better start, than the rest of the
web was offering!!
Regards,

Richard.

Actually, this problem could be easily solved, if there was only a single
line of explanation added next to each of the repositories in the install
instructions, so the uneducated or doubtful can be told and convinced
which package ships which flavour.
And yes, I was told to change this myself and given privileges to do so a
while ago, but I couldn't find the energy to fiddle myself into the
system. And I am still confused myself, cause behaviour seems to change
 from release to release a bit.

At the moment, I can hardly write cause my right hand is in plaster and
writing and pushing a mouse is a nightmare. So could not some less
handicapped and more literate guy add some explanations to the website?

Re: [Qgis-user] Organizing considering Dates

2016-09-14 Thread Tyler Veinot

Bia;
In 2.16.2 you can right click the column header and choose sort, this will
bring up an expression builder. In there just add the field you want to
sort by "Field_Name" or you can get fancy and say you want to sort by a
number and a string field. Then you would do something like
this "String_Field"||right(  ('' || "Numeric_Field"), 8) Notice the
"" being added, that is because the expression treats the number
like a string. Padding it with zeros sorts allows it to sort in order
1,2,3,4 if you do not pad you will end up with. 1,10,11,12,etc...
Dual sorting with date is a bit tricky but you can store the data as a
,MM,DD type and it should sort for you. If your date is stored in
another way, i.e. DD/MM/ then you will have to format it to ,MM,DD
for proper sorting, i.e. Year("Date")||Month("Date")||Day("Date") should
work to that effect.
As for sorting one column Ascending and another Descending I am at a loss,
have not been able to figure that one out but someone here might add to my
answer if you need to do that.
Additionally if your using an older version of QGIS that does not have the
"sort" function you could write the expression to a virtual field and then
sort it by clicking the column header of the new virtual field.
Hope that helps.
Tyler

Hi,
Could the scale be tied to an different object or a hidden map window in your 
layout?  If so, it could be giving you a scale for a different map window.

Not like it matters much in this case.
We have packages in qgis.org/debian/ against the plain versions of the
distributions (debian and **ubuntu**) and in qgis/ubuntugis/ packages  
against

newer dependencies from - and only from - ubuntugis-unstable.
Looks like it's hard for people to accept that there are also ubuntu  
packages
in a directory called debian and that probably makes them jump on the  
other

because it has ubuntu in it's name.


I was thinking about it last night (and I was up way to late) and it is  
a bit confusing for the casual user. They've installed Ubuntu (or  
mint/debian/>xubuntu/etc) and they may not understand ubuntu is based  
off debian. So like you said - they see debian but want to use Ubuntu.  
They go to >UbuntuGIS and they see the repositories for UbuntuGIS and  
the choice is unstable (and no one likes unstable software) and stable  
(which doesn't >contain the newest software). So you end up going "Use  
Unstable because it's stable and current".



Under my /etc/apt/sources.list.d directory I made a qgis.list file
and put the following in there:
deb http://qgis.org/debian xenial main
deb http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu  
xenial main
Why?  That are the packages not based on ubuntugis with the  
dependencies from

ubuntugis.


Do I have this wrong? I thought I had the repositories for the install  
correct based off the directions on qgis.org. Which I could completely  
have it >wrong. With the above repos I'm getting QGIS 2.16.x and GDAL

By defining the field "record" as xml, I can use XML functions within

Is this the sort of information you're after?

Re: [Qgis-user] QField error data source is not valid

2016-09-14 Thread Matthias Kuhn

Hi Reginald,

It's most likely that your project is not portable (i.e. paths inside
are not relative).

The documentation can be found here:
http://www.qfield.org/docs/

And about the portable project in particular here:
http://www.qfield.org/docs/project-management/index.html

Best regards
Matthias

[Qgis-user] QField error data source is not valid

2016-09-14 Thread Reginald Carlier

Hi,

I'm testing QField. On my desktop I made a project with a shape point layer 
made to inventarise streetbenches.
Then I put this project in the storage folder (DCIM) of my android phone.
On my phone I open QField and I browse to the project and I open it.
In stead of a map I see only a point marker in QField.
The error message I see is: OGR Data source is invalid()
What am I doing wrong?
Also I could not find any documentation on QField. Any pointers in this 
direction?

Regards,

Are you using the OpenLayers plugin?

[Qgis-user] Map composer. Wrong map scale

2016-09-14 Thread Carlo Cormio


Dear all,

I'm using QGIS 2.12.3 on Windows 10. After printing a map using QGIS map 
composer, I checked some distances and found that map scale was 
different from the expected one.
I set ISO A3, portrait, as page size. QGIS project has EPSG:3857 (due to 
the use of a google satellite layer), but most of the other layers have 
EPSG:32633. I tell you this in case it could affect prints.
Map scale in print composer was set to 1:5000, but when I measured 
distances (I also put a scale in the composition) I found it was more or 
less 1:3500.
The strange thing is that the ratio between the two scales is 1,41, that 
is exactly ISO A3:A4 ratio.

What did I do wrong? Is there a setting I missed?

Hope I gave all the necessary information.

Regards,

Carlo

Re: [Qgis-user] Raster calculator script failing for multiple rasters

2016-09-14 Thread R HG

Thanks Nicolas for your reply.

It does seem to be a memory problem, although it doesnt show the typical
"Memory Error". Without the script I could do that operation with the same
rasters. It involves four files and it is basically (a-b)*(c-d).

GDAL also failed to load all files at once, so I finally splited the
operation in 3. (a-b) then (c-d) and finaly the multiplication of the
outputs. Its much more time consuming but it works.

I still dont understand why using the tool directly from the UI it wrks and
it doesnt from the script. Will write back if I find the correct way.
