Re: [Qgis-user] getting started for a complete GIS beginner
Thanks! Slowly were building up the resources (exercises, notes, projects, references). We try to center our class towards free data, use of FOSS, collaborative content management, and Philippine geospatial applications. The course is more of vry basic understanding of GIS. There's really one major obstacle, up to know were borrowing time to the school's computer lab. With no dedicated pc's for GIS. Mostly we do exercises via a live-cd [http://epmgis.wikispaces.com/live-cd]. Feel free to use and edit the pages. maning On 11/27/07, Agustin Lobo <[EMAIL PROTECTED]> wrote: > Good job, excellent course organization! > I'll try to do a similar wiki with my students > > Agus > > Maning Sambale escribió: > > We are using QGIS and GRASS for our Basic GIS course: > > http://epmgis.wikispaces.com/ > > > > You might find some things useful there.

[Qgis-user] Distorted Map Display
Greetings all, I've seen this question asked a few times, but have never come across a workable solution. Whenever I open any map data from my area (Lethbridge, Alberta) in qgis (or grass) the maps are distorted (ie. east-west roads look longer than they should, north-south roads look shorter, or both). See this example: http://farm3.static.flickr.com/2375/2069180643_c7f175a11e.jpg?v=0 I've taken a screen dump of the qgis display and compared it to a mapedit display. These are both of the same shape file at the same projection (NAD83). The mapedit display looks correct...east-west (township) roads are two miles apart, north-south (range) roads are one mile apart (the pink square is one square mile). Even though the display looks wrong in qgis, the data is actually correct. I used the measure tool and came up with 1,640.30 degrees (which I'm guessing is meters) for the length of segment a, and 3,260.79 degrees for segment b. Segment b is (almost) twice the length of a, even though it does not look like it in the display. Just for interest...the "QGIS User Map" on the QGIS homepage uffers from this same distortion. Alaska looks quite a bit wider than it really is. So, is there any way to fix this or am I just going to have to get used to seeing (and printing) distorted maps from qgis? I've tried various steps to re-project the maps but the display does not change. Any ideas? Thanks in advance. -- Peter Pankonin, digitalcrucible There are 10 kinds of people in the world, those who understand binary, and those who don't. ___ Qgis-user mailing list Qgis-user@lists.qgis.org http://lists.qgis.org/cgi-bin/mailman/listinfo/qgis-user

Several years ago, I wrote a simple Mac-only thematic mapping application that does one thing: produce maps using data from a spreadsheet or text data file. It's less GIS and more the 'make map' analog of 'make chart." It goal is to serve users who work primarily with spreadsheets and want to visualize their data without learning too much GIS. It is useful only for the United States because it relies upon US Census boundary files. The user opens a data file first and chooses the id column. The application then retrieves boundary files based upon ids present. Finally the uses chooses a data column and classification technique. You may want to check it out as an alternative to learning GIS. However, it does much less than a full GIS application. Visit http://www.compassowl.com and follow the 'More info' and then 'quick start' links. The application can also be downloaded and will map up to 15 items in demo mode. If the 'quick start' tutorial (one page) makes sense to you and you are able to do all your data calculations using a spreadsheet, this may save you some learning time.

Re: [Qgis-user] getting started for a complete GIS beginner
Hi All --8<--snip-- As one of the developers of QGIS I've found this thread quite interesting. We certainly would like think that QGIS is approachable for novice GIS users but I guess there is always one more level of simplification required. While pondering this I couldn't help but think how more mainstream software like word processors or spreadsheets aren't really any better. They all make fundamental assumptions of knowledge of the problem domain. Word processors expect you to understand selections and fonts and styles and tabs and all sorts of things before you can do much more than just view documents. We have to balance the needs of novice users with the needs of those itching to do a little more than just the basics. I enjoyed Agustin's comments about being a contributor - I've always been of the opinion that just by using QGIS, people contribute to it - if for no other reason than the knowledge that people use and enjoy the software we work so hard on is to a large part the main incentive and reward for us to do the work in the first place. That said, I'd love to see the QGIS community step forward and address some of the topics raised in this thread. We once had an initiative to make little tutorial screencasts for QGIS, but I think more a more fundamental resource of good documentation would cover a llot more ground. Many of you using QGIS are GIS practitioners and lecturers etc and I'm sure you have numerous resources that you have created but not fed back into the project. We've also seen some fine examples in this thread of tutorials etc that have made their way into the public domain. With that in mind I'd like to offer the following challenge to the QGIS user community: - mobilise yourselves : create a working group (we have a document writers mailing list and a wiki that would be a good place to start). Make your selves known to Otto Dassau, QGIS Project Steering Committee member who oversees documentation and community effort. - outline your plans : draw up a bullet list of things you would like to achieve. From this thread I would make the following top level summary : - create free and open documentation for GIS concepts for new users to have a good starting point. Included lots of screenshots and images to make it easy to digest - document every tool in QGIS and contribute your work back to the project. If every person on this list documented just one tool we would probably have extremely complete documentation. QGIS has an infrastructure for context help provision but in most cases nobody has had the time to write such documentation. - where context help does not apply well, work with Otto to augment the use rmanual to close up the gaps. - define standards and working practices so that these things can be done in an orderly way with no duplication of effort, and so that documentation is consistent and coherent throughout QGIS. QGIS started as just a few simple little application that Gary wrote to view data in PostGIS. Many people plugged away at it and contributed small updates to make it better. We can do the same with the documentation - you dont need to be a coder / developer, all you need to do is be prepared to donate a few hours of your time and write about a feature in QGIS to contribute something valuable back to the project. QGIS 1.0 will be released next year and nothing would give me greater pleasure than to see it fully documented by the very people who are using it.

Re: [Qgis-user] getting started for a complete GIS beginner
Thank you Agus and Micha and Don for your explanations and patience. I understand the situation much better now. Agus is correct, of course, that one needs to learn the jargon of any field before progressing in it. But what's also important to note is that people new to a software project like QGIS might be users migrating from some other software -- who already know it -- and they might be users coming to it afresh -- who have to learn it someplace, but may be in process. I suspect that a product like QGIS which is presented as a simple GIS solution, and which has a very uncluttered and unthreatening (and therefore appealing) UI, will get more than its share of dumb users like me, for better or worse.

[Qgis-user] 0.9.1 Release plans
Hi All December is coming up fast and our bug triage has been quite a success with over 52 bugs squashed, many small patches and enhancements applied and a general focus on getting rid of bit-rot. Many thanks to the people listed here for the great contribution they have made to the bug fixing spree: https://svn.qgis.org/trac/wiki/BugTriage0.9.1 We are aiming to release 0.9.1 on December 10. Things were a little bit chaotic in our last 0.9. release because we were still figuring out how to get packages made using cmake after the code was tagged. I'd like to make things a little smoother this time since we have all the packaging stuff in place now. So I propose the following timeline for the release: Saturday 1 December: * String freeze in trunk. No more patches or updates should be made to any UI or tr() strings. Saturday 1 December -> Wed December 5 * Packagers make test packages for all platforms and commit any packaging related changes to SVN. Please note the GRASS folks have requested we use: http://grass.itc.it/grass63/source/grass-6.3.0RC2.tar.gz For platforms where we are bundling grass together with QGIS (Win and Mac really). Markus to advise if there is any change in the above advisory. * UI Translators update any small string changes that have arrived in SVN Trunk over the last month. Wed December 6 - Tag Release * Tag release as 0.9.1 in SVN. * Create source tarball * Send out request for final packages Wed 10 December - Press annoucements and publicity Notes: - Otto - do we need to do any coordination for the users manuals? After 0.9.1 is tagged work can continue in trunk. Please note that unlike how some other projects work, we are using trunk for stabilisation. This means beyond bug fixing, any new features committed to trunk should first be approved by the PSC. If you want to work on some new features, you should do so in a branch - contact us if you feel the need for a new branch. We will aim to do folllow up 0.9.2 (or 0.10.0 release number to be decided by PSC) release with possible merges of raster transparency branch, advanced editing branch and diagramming branches early in the new year. If you would like to see these features incorporated into trunk, please test them and report bugs! Test packages for the above branches have been making their way into: http://qgis.org/uploadfiles/testbuilds/ Many thanks for all your help in reporting and squashing bugs. The bug triage idea will be repeated after the next round of features get released. I'm hoping with a few more bug triages we can get rid of all the minor annoyances and land up with a core list of issues only in the bug queue.
