Just wanted to do a quick straw poll to see where and how QGIS is being used in the UK.

1. Organisation
2. Use: Full adoption / in migration / used by few / just me.
3. Number of users
4. Data storage - postgis / sql server / Oracle / flat files
5. Savings made.

Would be great if you let me know ahead of Tuesday's user group.

Thanks,

Matt

1. NPA (small environmental consultancy)
2. Full adoption of FOSS4G stack not just QGIS (mainly 1.8 actually as most users do not need functionality beyond what it provides, I also find it to be stable and install friendly, although I am hoping to move eveyone up to 2.4 soon)   
3. 3-4 regular, 10+ casual 
4. PostGIS but of course (Some shp and csv for intermediate) 
5.  Mapinfo licences for 2 years, about 4k in monetary terms (but the use of FOSS has meant many other users within the company can have access to GIS, leading to a much wider adoption of GIS in general.)

Has any one had experience of using QGIS over a citrix network?

We have someone coming next week to the user group who is asking this question.

I'm thinking of doing a short presentation at the next QGIS event entitled:

"Things you always wanted to know about QGIS but were afraid to ask..."

If you've got something you want me to add no matter how small give me a shout.

How about "how to create a custom QGIS installation using config files"?  Not that I'm gonna make it but I'd be interested in seeing the slides.

I saw this: Self-Paced Introduction to QGIS Course
 
A new course on learning the open source GIS package, QGIS, is being offered to free via Canvas, an open-source learning management system.  The QGIS course, which is in beta, was developed by Richard Smith, an Assistant Professor at Texas A&M University-Corpus Christi, and Kurt Menke, a GIS Specialist at Bird’s Eye View.  Students can start enrolling now in this course shell and provide constructive input before the course is published in August of 2014 on Github.
The open enrollment course is self-paced, which means unlike a MOOC, there are no instructors to provide ongoing support.  There is a discussion section where students could post topics and potentially receive peer support.
There are seven modules which contains a lesson introduction, videos, and a lab which includes package GIS data.  The stated purpose of the course is to guide students in exploring and managing GIS data using QGIS Browser and QGIS Desktop (version 2.2).  The course lists the learning outcomes as:
The student will describe the fundamental concepts of Geographic Information Science and Technology.
The student will demonstrate proficiency in the basic functions of geospatial software.
The student will demonstrate awareness of fundamental remote sensing and spatial analysis techniques.
The student will demonstrate basic proficiency in map creation and design principles, including thematic map display, employment of map projections, and cartographic design.
The student will demonstrate proficiency in the creation and acquisition of spatial data.
To register for the course visit: https://canvas.instructure.com/enroll/LA4DR9

Hi everyone, we have a mixed MapInfo / PostGIS setup here and are in the process of slowly migrating all our MapInfo layers into PostGIS.  We are finding that when our MapInfo editors want to edit a layer in MapInfo it says that "the destination table is currently locked".  I think that because we have the same TAB file open by another user and being viewed in QGIS then QGIS is locking the TAB file so that editing isn't possible.  This problem will probably disappear once we have all our data in PostGIS but until then, has anyone got any ideas how me might avoid this issue. Thanks Dave.

Thanks for all the replies - re: the map catalog Mike, we have flat TAB files so don't have a mapcatalog but if there are any utilities that may be of use to us then by all means put them on the github - all gratefully received.  We can get most of our TABs into PostGIS pretty quickly Ross but a few are linked to and edited by 3rd party software which is reading flat TABs at the moment.  This situation is changing over the next few months though.

Openlayers plugin/Google satellite not aligned...

Anyone noticed the Openlayers plugin/Google satellite not aligning with OS anymore? Everything was pretty reasonably aligned for me until very recently. I'm using the OSTN02_NTv2.gsb grid transformation (http://dragons8mycat.wordpress.com/2014/03/03/gis-tips-getting-ostn02-to-work-with-qgis-2-2/) but even if I use the 'standard' QGIS 7-parameter transformation it is similarly misaligned...

I know there are issues specifically with the satellite only layer at high zoom levels. Try using the hybrid layer.

Legend elements on Composer in Map Units

I've been playing with Composer in 2.2 and came across the following peculiarity with the symbology of lines. The symbols in the legend do not conform to the size specified and appear to be affected (in some non-obvious way) by their size in map units. In order to separate out the road layers (in a group) I needed to use a large separation size, and also the symbols seem to extend closer to the text than is desirable. (I can produce a rather nastier version of the legend if any one wishes to see it).

You can separate out all the different elements making up the legend by selecting it and then editing the item properties under Spacing.

Have you checked the QGIS issues list to see if someone has reported it?  If not, you should submit a bug report / feature request.  https://hub.qgis.org/

Morning all,

I'm trying to style some flooding probability data from SEPA.  It's in PostGIS and I'm using QGIS master (same issue in 2.0 and 2.2 though).  My polygon layer has a probability field with values H, M and L (for Hiya, Morning and 'Lo)  If I select a categorised style using the probability field I get the expected three values.  And an extra one.  And the data is drawn using the style of the extra category - in the screenshot the pink lines and not the blues as expected.

So, is it a QGIS style engine problem or a PostGIS data problem?  I should add that the same data from PostGIS draws perfectly in ArcGIS and is styled as expected.  Maybe I should switch back...

Anyone else had similar experiences?

About this community

The UK Quantum GIS (QGIS) User Group has been setup to primarily provide a forum where UK QGIS users can share information and experiences of QGIS and other Open Source GIS resources. The purpose of forum is not for individuals to ask general question about QGIS, these should be directed to the GIS Stackexchange.

The GraphicalWeb 2014 conference in Winchester from August 27 to 30 may be interesting for the UK QGIS user community. See http://www.graphicalweb.org/2014/

Next to the regular presentations, keynotes and panels there will be introduction courses for QGIS, R, d3, WebGL, leaflet and others. The QGIS and R courses are taught by the BBC visual journalism team ;-) See http://www.graphicalweb.org/2014/index.shtml#day_3 for the workshop schedule.

I will be there. Would be nice to meet some UK QGIS people.

Hi All,
I'd now like to announce the first Midlands QGIS user group meeting on Tuesday November 25th, to be held in Warwick. More details will be forthcoming in the future months, along with ticketing and a programme. But for now you might want to pencil it into the diary. We're anticipating a nominal charge to ensure attendance and help with costs (£20 corporate types; £10 everyone else).

Suggestions for topics of interest or speakers etc are welcome.

More details soon(ish).

Hi Mark,
Good point, we did consider that but unfortunately we're constrained by the availability of the rooms we're using. We can't get them any earlier and if we go later it'll be during the xmas period.

If you fancy coming to sunny Dartmoor to learn more about QGIS and hear what others are up to then pop along to our  QGIS-UK South West event there's still plenty of space available. 

https://www.eventbrite.com/e/qgis-uk-south-west-event-tickets-11605007891

If you've already said you can make it would you mind going to get a ticket as I need to start getting the orders in for lunch.

Cheers

Matt

N.B. good weather not guaranteed

Afternoon all,

Having a slight problem with zonal statistics, I get this message (see below) when I attempt to use it on my workstation un-yet it works fine with the same dataset on my colleagues.  I have tried reinstalling QGIS and all of it's components using OSGEO4W but I have not had any joy.

Any ideas?

I think I have gotten to the bottom of this but perhaps a few people could try it and confirm?  I think that the issue is copies of QGIS installed with OSGEO4W.  I have tried to analyse the same set of raster data (Carbon emissions form NAEI) on three machines with the OSGEO4W version installed and two with the standalone installer version installed.  It worked on the machines with the standalone and threw back the error (in the screen shot) on the OSGEO4W machines.

Can anyone suggest a suitable device for using QGIS in the field?.  We're happy to spend for a good solution.   We are ok with setting up QGIS, forms, spatialite etc.

Text annotations and the Print Composer

I've submitted a bug report (https://hub.qgis.org/issues/10400) about this but it would be great if any of you could confirm this for me.

Create a bunch of text annotations across the map canvas.  Create a print composer and add a map frame.  Zoom in so you can see some of your text annotations but making sure that some are outside the map frame or "off screen".

Items drawn on the map canvas should stay there and respect the boundaries of the map frame drawn in print composer.  See attached image for an example.

Hi Nathan, rules based renderer didn't work.  What did work though was going back to the source data and checking it and the PostGIS table.  The probability field was a char field 50 characters wide, i.e 'H and then 49 spaces'.  I reloaded the data into PostGIS with the field as varchar and now it works as expected (although I still get the extra category added and I can delete it) cc +Phil Barlow +Morgan Commins

Hi All
don't know if this is the correct forum - if not I apologise.
I am a new user and work with a local, Telford, Volunteer Community Archaeology Group. I am struggling to get to grips with QGIS, although I am an experienced CAD and IT user.
Is there anyone nearby who could spare a few hours to set me on the straight and narrow. I am happy to put my work on a memory stick and travel. I use QGIS under Win 7.

Make that 4 to turn up - depending on what day of course. Though sadly from my point of view I don't know enough to contribute - all take and no give I'm afraid. Also depends on cost - I'm retired.
