If not, create a field and populate with unique label based on the top left lat/long value. Shapefiles are not a single file. If you look in your directories you will note they consist of a SHP, SHX and DBF file. The DBF file is a standard database file that can easily be imported into Excel, Access or similar product. This DBF file contains your attribute data. These DBF files can be safely read by external packages (Excel, Access, LibreOffice Calc). Don't update or change them however as it will cause problems with the SHP and SHX files. Say you are using Excel. Import each DBF into a sheet. Since each record is tagged with a unique QDS code you can then sort and summarize all you want. If you set the DBF files up as a database source then as you update your Shapefiles in QGIS the changes will appear in Excel. -- Cheers Simon Simon Cropper - Open Content Creator Free and Open Source Software Workflow Guides Introduction http://www.fossworkflowguides.com GIS Packages http://www.fossworkflowguides.com/gis bash / Pythonhttp://www.fossworkflowguides.com/scripting ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Re: [Qgis-user] Stress about release plans
Hi All, It is hard to figure out where in the conversation to interject but Victors counter-suggestion appears appropriate to me. Being involved in several open source projects, creating tutorials for these and having in the past been involved with trying to contribute to the main documentation for these packages it is obvious to me that developers need to be involved in documentation. Users rarely are able to decipher code and trying to figure out when and how to use a particular feature can be quite daunting even for the most experienced person. Developers must provide at least basic information on what each new feature does and what each feature (drop down box, radio button, etc) is for. Without this users need to ferret through hundreds of emails and forum posts, and pester the developers anyway. It is easier for devs to provide a simple skeleton -- this does this, that does that, here is a link, check out this bug etc. All this information is available at the developers fingertips while they are working on the new feature anyway -- it is just committing 30 minutes at the end to put some details down on he page. With this basic information, documenters are better equipped to present the feature in context and explain how it should be used. On 22/07/14 20:01, Victor Olaya wrote: +1 to what Otto said. Very good point. Those creating training materials should coordinate and help the core QGIS documentation (both the manual and the training manual) improve. The solution is very simple: Require up to date, accurate documentation for all commits of new features. This is one for the PSC. After all, what's the point in having tons of features if no-one knows how to use them or what they do? Will it slow down new feature feature commit? Probably, but I figure that's a small price to pay for actually having documentation. And from that documentation, universal training materials can be developed much more easily. -1 from me. Features are also documented by people using them, not just by the devs. We like to say that you can contribute to open source projects not just by coding, but if we do that, I don't think we are going to get many contributions from users, leaving the documentation to be written only by developers. I try to keep the Processing documentation up to date, but only documenting the interface itself and the framework, not the algorithms. That's the reason why a large part of algorithms in Processing are not documented. Fortunately, some users have contributed documentation, and they have added descriptions of several algorithms, but the have done that *after* using the (hitherto undocumented) algorithm and becoming familiar with it. No one is going to document something that he cannot use yet. Let's encourage developers to commit features when they are well documented, but let's also give some flexibility, since that's not always going to be possible. my 2 cents Cheers Víctor -- Cheers Simon Simon Cropper - Open Content Creator Free and Open Source Software Workflow Guides Introduction http://www.fossworkflowguides.com GIS Packages http://www.fossworkflowguides.com/gis bash / Pythonhttp://www.fossworkflowguides.com/scripting ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Re: [Qgis-user] QGIS 2.4 open att.table makes noise and works slow
This is just an extension of the wrong codepage. Chatter in the forum suggests that people that use special characters in the directory names have sound. Change the directory to just have 'ASCII' characters and all works. As I stated, rendering a symbol that the program or OS does not understand can cause the system to behave incorrectly. I had a similar issue with using the degree symbol (as for Degrees Celcius) in a spreadsheet. The whole application went mad with the image being rendered all over the place and sound coming from the speakers. Removing the symbol got ride of the problem. If the file does not render then the directory name may be the issue. If only the attribute data causes a problem it is most likely the data in that table.

Re: [Qgis-user] How to get rid of the rest of the World?
Marcus, I think what you are asking is can you just view the area that you are working on and have QGIS hide or filter out those feature not within the area of concern. From my understanding is no. Well not exactly. My understanding is that shapefiles will allways be processed regardless of whether they are visable. Feature may not be visible if they are outside the view or transparent. You have two simple solutions to this problem. 1. Create a routine to, or manually, clip all the shapefiles in your project based on a reference polygon bounded by your lat/longs. 2. Create a polygon covering the world and punch a hole through it, essentially creating a window bounded by your lat/longs. The polygon can be made opaque/white making it the same as the screen/page or semi-transparent, essentially fading the underlying features (nice effect in reports).

More specifically, how to make a rectangular area of longitude and latitude coordinates that enables to cut away the area not needed in other layers? Since stuck with a quarter of the World or even the entire World in my little project. This question is for shape file layers mostly, have not gotten to the .tiff yet. They are not global though larger then needed. So a universal solution for both types would be nice. Is there a python console command to do this? Is there a plugin to do this? Is there a online service to create such a layer? Is it possible from within QGIS? Have tried the make a rectangle plugin, it cuts out zero features. Also tried clipping with a layer of not the right shape and it says that they do not have the right projection, even though it looks as they do, and end up with a blank layer. Sure plenty people have this problem, though the forums do not have any clear explanations as I found nothing that really explains, even youtube got one but that is for regional borders. Is there some way of just knocking in the longitude and latitude to do this? Please assist. Do not get why this should be so difficult. Why does not QGIS ask first thing which area of the planet you wish to work on a project? And then just filter out it automatically when you load layer that include more than that? Perhaps this could be a feature of a future release? With hopes for many answers and simple solutions. I repeat just want a specified area that easily can be determined by longitude and latitude coordinates. Yours hopefully..

Cheers Lester ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user Lester, Most of the responses to date have focused on the print composer. Another option is to create you standard non-geographical map in UTM, Lambert or whatever. Turn on reproject on the fly. Then, add a new vector file representing the boundaries of the gradicules you require. If viewed in this vectors native projection it the grid would have parallel lines but when reprojected it curves as you would expect. See Figure 4 on my tutorial on Datums and Coordinate Systems used in South-eastern Australia -- this is a good example of the technique. http://www.fossworkflowguides.com/gis/tutorials/7/index.html I have 5' and 10' grids for Australia that I created using Sextante, which is now available in QGIS. So in summary, rather than use the print composer to put gradicules on, add the gradicule as a vector file like any other vector file. The only issue is that you need to insert labels yourself in places that make sense within the map -- rather than external to the 'map proper' as you would expect in a gradicule created by the print composer. -- Cheers Simon Simon Cropper - Open Content Creator Free and Open Source Software Workflow Guides Introduction http://www.fossworkflowguides.com GIS Packages http://www.fossworkflowguides.com/gis bash / Pythonhttp://www.fossworkflowguides.com/scripting ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Re: [Qgis-user] Can I add a shapefile from a network location to QGIS 2.0?
You can mount a Windows volume quite easily on the fly or permanently by configuring you fstab file. The command to do this is... mount -t cifs It does take a bit of fiddling to get the credentials to automatically work but once setup the process is painless. The issue you are encountering has to do with spaces on the name. For example, if I copy a shape file to the My Documents directory on my Windows Mount, QGIS and gvSIG does not see the file. If I put the file in Data and ensure the filename has no spaces, e.g. My_Shape_File.shp then the issue disappears. The file appears in the vector open dialog box. I hope this helps.

Re: [Qgis-user] Getting landuse information for several circular polygons
Manuel, Once you clip the layers, break the multi-part components apart use the following menu sequence Vector Geometry Tools Multiparts to Single Parts -- then they can be summed. You will need to relate you bits back to your buffer layers however, to match which bit goes in which buffer. Alternatively, and easier in my mind, you could Union your layers. This creates an exploded layer where each bit has attributes of both parent layers. You can then delete those elements that do not have a buffer value. Two steps but less messy.

Re: [Qgis-user] Getting landuse information for several circular polygons
Manuel, I am not aware of any specific tutorials for doing this work in QGIS. No offense but these tasks are relatively basic. Your comment I found this task kind of difficult to do in QGIS is suggestive that you have difficulty in either basic GIS concepts or extrapolating your existing knowledge from a commercial package to QGIS. *Assuming you stick with QGIS* Micha Silver has provided a tutorial called GIS basics with Quantum GIS http://www.osgeo.org/node/1058 that may help you master the basics. The QGIS website has a great section called How do I do that in QGIS? that covers alot of material http://hub.qgis.org/projects/quantum-gis/wiki/How_do_I_do_that_in_QGIS#How-do-I-do-that-in-QGIS. Note the large number of videos on youtube -- sometimes seeing it done can help. *Assuming you are considering an alternative* The OSGeo Educational Content Inventory also has a wide variety of other educational material available that might also help fill in the gaps. http://www.osgeo.org/educational_content Finally, QGIS is not the only fosGIS out there. Check out what is on offer on the LiveDVD (http://wiki.osgeo.org/wiki/Live_GIS_Disc). Personally, I found using gvSIG relatively easy when moving from ArcView. Unfortunately the bulk of the tutorials are in Spanish; unlike QGIS which are predominantly in English. See my website for details and a list of ecological tutorials I have prepared to date. *Final Comment* All this material is predicated by the premise that you actually know what things are called. Reprojection and transformation is a good example. Projection, SRS and CRS another. When stuck, posing a problem on the forums can help as others can help you with terminology and suggest methods to solve you problems. I hope this helps.
