[OSGeo-Discuss] How to convert lat/lon to x/y (in pixels) for a given GeoTiff file
Hello all, I'm a Geo newbie working on a weather project using a lot of epsg:900913 country maps in GTiff format. These country maps will be converted to jpg and will be used as static background images for doing javascript-powered weather maps. I am trying to find a way to translate the lists of geodetic lat/lon points (ICAO stations for each country) to x/y coordinates for the relevant country map. Could you suggest a software tool for that purpose? The original maps were WGS84 Equirectangular and it was very easy to get x/y pixel coordinates from lat/lon, but the maps were too elongated, so I translated them with gdalwarp to epsg:900913, and this is were I get lost. Any suggestion would be higly appreciated... __ Do You Yahoo!? Tired of spam? Yahoo!

[OSGeo-Discuss] Can we use a LiveDVD for workshops and labs at FOSS4G 2009?
I'm wondering whether it will be achievable and desirable to use a GeoFOSS LiveDVD as the only installed operating system at workshops and labs at FOSS4G 2009. If we can achieve this, it will have many benefits: * Labs will be easier to configure and setup * We would avoid M$ licence costs as the image is based on linux * After FOSS4G we would have a proven LiveDVD which can be used for workshops and labs at smaller OSGeo events around the world The cost to us as a community is that we will need to invest in getting all our software packaged up into the LiveDVD (which of course will have many spin off benefits) as per: http://cameronshorter.blogspot.com/2008/10/creating-geofoss-distribution-pipeline.html So my questions to communities are: Do you and your project think you would commit to packaging your project into a debian based LiveDVD before FOSS4G in October 2009? For presenters, would you want to add tutorial material to the LiveDVD, which would mean using an Open licence like Creative Commons?

So we only had to deal with three different hardware-types. Our first idea was to use Live-DVDs and create one broad LiveDVD for all workshops or an individual LiveDVD-Image for each workshop. This wasn't practical, because it would have been necessary to burn a big bunchof DVDs. The other problem we had to deal with was, that one type of notebooks we used were IBM tablet-PCs - without any DVD-drive. So it came out that the best solution might be to configure a big Server to work as an tftp-boot machine and boot all the Workshop-Images via PXE. It was very impressive how good it worked. We used a custom PXE-boot prompt where the participants were asked to choose there Workshop and the chosen individual Workshop-image booted via Net. One very good side effect was that it was possible to provide the individual workshop-images days before the conference to the workshop leaders as iso-Image. So they had the possibility to check if the Image works exactly as expected. Updating and building a new image took about half an hour. Of course you need a good network as requirement. Our Server just had 1GBit-Port available. The Notebooks were connected via 100MBit. It was o.k. to boot 20 Notebooks parallel - this was enough for our maximum of two parallel workshops. The boot of all systems took about 5 min (not the best you can get but o.k.). After the boot the network traffic wasn't a problem. Another side-effect was that we were able to have a Internet-Cafe also using PXE-boot. The visitors could use the "normal" prepared @-Cafe-Image or boot one of the Workshop-Images to have a closer look after they participated at a workshop, ... For future conferences I'd recommend the following equipment: - - 1 workshop-server, able to spit 10 GBit - - each workshop room connected with 1GBit (up to ~5 parallel workshops possible) - - each notebook connected with 100MBit (up to 20 notebooks/workshop possible) Very nice scenario - I'd like to see this working. Marco P.S. of course the best side effect was, that we didn't have to install anything on the notebooks. We wanted to have a M$-free conference. And our university computing centre told us not to modify the Windows-Installations on the notebooks :-P By the way also the session-notebooks were only equipped with OS-Software (Ubuntu/OpenOffice/...) and the speakers could handle that. The FOSSGIS 2008 was definitely free as Freibier in Freiburg ;-) Especially if you keep that participating the conference is for free (you have to register - about 500 did) only the workshops cost about 80EUR each.

I've heard of people using Slax or systemrescuedisk to help get the net boot process running, but I haven't tried it yet.

Re: [OSGeo-Discuss] Can we use a LiveDVD for workshops and labs atFOSS4G 2009?
I see that Knoppix is debian based, like the FOSS4G 2008 LiveDVD which started from a xubuntu distribution. As I understand it, there are 2 ways to build a debian based LiveDVD: 1. Bundle all packages up as .deb files, then you can apt-get the packages into whatever linux based distribution you wish, including LiveDVDs. 2. Manually install packages onto your linux computer, then take a snapshot of your image, as a LiveDVD. Ideally, the .deb packaging can be rolled into each project's build process thus simplifying distribution and LiveDVD build processes, which should ease GeoFOSS installation in numerous distributions and LiveDVDs, and hence increase GeoFOSS uptake. This does require an initial up front investment from each project in setting up a .deb build process. I think that the investment is worth it based upon the marketing and outreach projects will receive. Is .deb packaging something that projects are interested in?

RE: [OSGeo-Discuss] Can we use a LiveDVD for workshops and labs at FOSS4G 2009?
Hi folks. As you all know, there is a growing interest in open source for Windows. Especially with Microsoft's release of its developer tools in free "express" editions and the availability of such tools as SharpDevelop and Mono. MapWindow is .NET based and the bulk of our developers and users are strictly MS based. I don't think this makes them any less human, it just says that their threshold for open source is set such that a $90 Windows operating system is considered acceptable but a $1 GIS is not. We had a great turnout at the MapWindow lab and worshop in South Africa and got lots of "hey it's great to see .NET open source GIS here" comments. So, call us mudbloods, but it's an approach that we see has a huge added value for lots of folks. Bottom line, if having Windows on some lab computers doesn't add a huge expense, then we'd hope that Windows based labs and/or workshops would be encouraged. Indeed, consider the opportunities for demonstrating QGIS and GRASS and others on Windows to help convert Linux avoiders over to OSGeo. - Dan -Original Message- From: Dave Patton <[EMAIL PROTECTED]> Sent: Sunday, October 19, 2008 3:02 PM To: OSGeo Discussions Subject: Re: [OSGeo-Discuss] Can we use a LiveDVD for workshops and labs at FOSS4G 2009?

I have no skin in this game, but I would second the above sentiment. While "not free as in beer" should not be as much of a problem as "not free as in speech," ignoring Windows is perilous and foolish.

I think it would be more appropriate to change developing to using. It is much slower from my experience trying to develop on a windows system, and if you're talking Open Source, you really should be(wish list) talking cross platform or open platform. I'll also toss in that the free versions of Visual Studio leave out certain things that make it impossible to compile certain apps or to compile them without Visual Studio. Don't get me wrong, I think Open Source is open source in all it forms and I appreciate it all it's forms. But even if you only use windows or linux or mac acknowledging the others and working across is a good thing.

Re: [OSGeo-Discuss] Can we use a LiveDVD for workshops and labs at FOSS4G 2009?
Thanks Daniel, It is good to know that there are projects which depend upon Windows. For MapWindws, (and any other windows based workshops), what should we install on our lab computers? Can we cover everything using OSGeo4W? Or should we use something different? Maybe we should set up the lab computers to dual boot with Windows + OSGeo4W / LiveDVD. Daniel P. Ames wrote: Hi folks.

So my questions to communities are: Do you and your project think you would commit to packaging your project into a debian based LiveDVD before FOSS4G in October 2009? For presenters, would you want to add tutorial material to the LiveDVD, which would mean using an Open licence like Creative Commons? I would start by asking a different question - does anyone foresee any issue with not having MS Windows available as an option for Workshops/Labs for FOSS4G 2009? We might not want to restrict the discussion to "OSGeo projects". What if a Sponsor, or Exhibitor, or 'some software company', or 'some non-OSGeo project' submitted a proposal to deliver a Workshop/Lab, and it merited consideration for inclusion in the conference, but it required MS Windows? Were there Workshops/Labs at FOSS4G 2008 that could not have been delivered without having MS Windows? If we assume that there was 'some need' for MS Windows for FOSS4G 2009, but that it wasn't needed for "all the PCs", how would people react to Workshops/Labs that required MS Windows also requiring a higher registration fee? (i.e. higher by the incremental cost of the license to use MS Windows on the PC for the Workshop/Lab) P.S. It helps if everyone uses the term "Instructors" when referring to Workshops/Labs, because "Presenter" makes people think of "Presentations", and sometimes that causes confusion. -- Cameron Shorter Geospatial Systems Architect Tel: +61 (0)2 8570 5050 Mob: +61 (0)419 142 254 Think Globally, Fix Locally Geospatial Solutions enhanced with Open Standards and Open Source http://www.lisasoft.com ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

But to split hairs, if MapWindow is .NET based it is not entirely open source as it is dependent on a closed source platform. Now if it also works on Mono (as in developed with that in mind), that's no longer true. Does it? I would also suggest that developing an open source project inside an environment controlled by one of the companies most damaged if the open source development model becomes the norm is inviting failure. OTOH I would be a supporter of having Windows available on the LiveDVD in VirtualBox, partly for reasons you suggest below and partly so "Linux avoiders" can realise you can also gain from avoiding that $90 tax on your PC. The use of Windows in VirtualBox should be legitimate if the host machines have licences. Legitimate as in defendable at least; not sure how pragmatic Australian courts are on software licencing and some of the more ridiculous terms companies include in them... NB would require two versions of the DVD as it could not be distributed including the Windows VM. And come to think of it, given Window's special size requirements as an OS, it would probably require a Bluray disc instead of a DVD ;) Chris > > We had a great turnout at the MapWindow lab and worshop in South > Africa and got lots of "hey it's great to see .NET open source GIS > here" comments.
