June 2004 there will be the LinuxTag in Karlsruhe/Germany, the largest fair and conference about "Linux and free software" in Europe. The slogan is "Where com meets org", therefore a lot of big and small companies and several community projects are represented. The conferences consist of a wide spectrum of different topics, where everybody findes several interesting ones. German address: http://www.linuxtag.org/2004/linuxtag.html English translation: http://translate.google.com/translate?hl=en&sl=de&u=http://www.linuxtag.org/2004/index.html I think this would be a good place to me for the "Open Source GIS Community" too. On the QGIS channel I suggested it to the other developers there and three (with me) of the europeans will come to the LinuxTag. It'll be nice for getting to know each other better, talk about interesting stuff and ideas and certainly heavy hacking. As QGIS has a plugin for opening GRASS stuff now and we want more GRASS integration in the future we thought we could bring the idea of a "Open Source GIS Community" meeting also to the GRASS people, as a lot of the main developers (Markus, Radim and the guys of Intevation) and users are from Europe or even Germany and it therefore would be easy for them to attend. Intevation will have a booth there (they had also the last years) afaik. Any interest? About my experiences with LinuxTag: 2002 I were there only for one day, joined some lectures and looked at the different booths. 2003 I were with a friend for two days. He works on php so we mainly were at there booth, we got to know the guys there, had some coding sessions (I helped the guys of DBDesigner4 to build a RPM for there project) and were invited to some beer in the evening, after the LinuxTag, at a need beer garden. The beer was sponsored by MySQL (who was also there). It was a nice evening and we went to bed late, at the stadion of the University, in sleeping bags. On the next day we also joined some lectures and looked at different projects. Beside the congress center is a big park which also contains a zoo, so for relaxing you can go out, lay on the grass, have lunch there or program on a laptop. WLAN is available in the fair and the conference area and perhaps in some parts of the garden too. Is there now any interest on meeting there?

There are many Free Software solutions for this. www.freegis.org has them, but it might take some knowledge to get them assembled. (This would not be different from proprietary solutions, though.) Note that you asked for a pure GNU solutions. To be very precise only software belonging to the GNU project, are purely GNU. The GNU project contains many key component of Free Software systems, but it is not possibible to build software purely from GNU components. Common GNU/Linux operating systems for instance contain Linux and X11. It is possible to build operatings systems with applications that only run Free Software! Most applications listed on www.freegis.org are not part of the GNU project, but all of them are Free Software. > In my projected app ach point is a customer, so my intention is to use a > projector to show a map over the wall at the control room, and ligth on a > spot in the location of the customer that has an event. > In the movil computers in the cars, i wish to spot the customer > location, and the possibles iterations from the point the car is to the > customer location.

You are comparing Free Software solutions with proprietary solutions. http://intevation.de/~jan/infos/dont_oppose_commercial_and_free_software.en.html There are many commercial Free Software solutions to your problem.

For fun I like to call it GNU/Linuxtag or GLT, because it actually is more about the operating system and not the famous kernel. It indeed is an impressive event, but this is also one of the problems: There is so much stuff going on that it is very hard to actually have a relaxed special purpose meeting. > German address: > http://www.linuxtag.org/2004/linuxtag.html > English translation: > http://translate.google.com/translate?hl=en&sl=de&u=http://www.linuxtag.org/2004/index.html > > I think this would be a good place to me for the "Open Source GIS > Community" too. I consider myself part of the "Free Software GIS Community". It is important to me that I'll make a stand for the mid term, business and social aspects of Free Software. > On the QGIS channel I suggested it to the other developers there > and three (with me) of the europeans will come to the LinuxTag. > It'll be nice for getting to know each other better, talk about > interesting stuff and ideas and certainly heavy hacking. > > As QGIS has a plugin for opening GRASS stuff now and we want more > GRASS integration in the future we thought we could bring the idea > of a "Open Source GIS Community" meeting also to the GRASS people, > as a lot of the main developers (Markus, Radim and the guys of > Intevation) and users are from Europe or even Germany and it > therefore would be easy for them to attend. > Intevation will have a booth there (they had also the last years) afaik. Yes, Intevation will have a booth. Drop by and say hi if possible! Intevation's GLT booth will be focused to explain our GIS services and other commercial Free Software offerings to potential customers. This is a bottleneck in the success of Free Software in my view: We need to connect to the users with more political and financial power. In the GIS area I consider the barrier higher as with other areas of Free Software use, like the desktop or webbrowsers. > Any interest? For the two reasons above a FreeGIS hack session at GLT would overload my schedule. I would love to do one, though, as hacking Thuban and GRASS development infrastructure is fun. So maybe next time for me. Hope to see you at GLT, Bernhard ps.: Mail-Followup-to set to freegis-list. -- Professional Service around Free Software (intevation.net) Experts for complex webmapping!

(b) INPE is the Brazilian organization responsible for building the satellite and distributing CBERS imagery. (c) INPE has adopted a data and software policy that prescribes that, whenever possible, data and software should be distributed using a free policy. That policy is already adopted with regards to our GIS software (TerraLib/TerraView), and the GIS data on Amazon deforestation (see www.obt.inpe.br/prodes). (d) Based on this policy, CBERS-2 imagery is being made available for free, without any restrictions, to Brazilian users since 20 April 2004. (e) Since CBERS-2 is a joint chinese-brazilian development, the data policy for international users has to be agreed by both parties. The joint negotiations on international data policy for CBERS-2 are still under way. Before a joint policy is agreed, INPE cannot distribute CBERS-2 data outside Brazil.

I am new to the list so please excuse if this already became an FAQ... I read the FAQs, HowTos and docs I was able to find on the net but did not come to any conclusion, so I am asking here now. What I want to do is to start an open project to create street maps. I intended to use GPS data as base for the maps since GPS devices have become such cheap and many users can afford one - subsequently there are many potential contributors out there. What I am looking for are software tools to create decent maps from those GPS tracks. What is needed is a quite comfortable tool to first import the GPE/NMEA data into some GIS application. From my research I found that maybe GRASS could be a potential target - though GRASS seems quite complex to use. The next thing that needs to be done is editing and annotation, maybe Thuban can be used for parts of this. The tracks have to be split into seperate streets and the streets have to be identified and annotated. And last but not least the resulting data has to be pretty-printed so that a user can finally use those resulting maps. Lot of stuff! And above all a colaborative method has to be found so that users can contribute GPS recorded tracks in a manner so that an already recorded street is not added twice to the resulting database - the second reconrding could be used to achieve a higher accuracy? I would like to start the whole project by making myself more familiar with the whole GIS and mapping system. I have to admit that I know how to operate my GPS but know almost nothing about GIS. What I do know quite a bit about is (system) programming. I could offer to create the data aquisition application, i.e. a nice user friendly frontend application that records GPS tracks in a certain format for various devices - PDAs, notebooks, etc. What I need help with, at least in form of hints, is the GIS system, i.e. how to import the GPS data in a system like GRASS, how to postprocess it and how to generate some form of map from it. The result could become a community effort and project. I do intend (take this as my word and promise) to make this like an opensource project, i.e. have users contribute GPS data, help annotate, etc. and make the result available to the community again. All software sources and all intermediate data should also be open to all interested users under a free license. In some years we might be able to have a decent street map set for several countries and maybe one day an opensource navigation software. I am willing to spend my spare time on writing software for the areas I have some expertise with and to contribute my GPS data. But I need help for the GIS part. At the moment I want to investigate the feasability of such a project. If anyone here on the list is interested in such a project you are absolutely welcome to contact me by personal email or, if the others of the list agree, discuss such a project here on the list. I am open to any suggestion! If this idea has already been discussed, please excuse my ignorance and point me to some archive of that discussion.

As end users, we are trying to set up a complete GIS system, based on free software only. I must say things are not very easy, but generally everything is quite functional and powerful. One issue that remains, I believe, is easy map printing (ArcView style). As I see it, several solutions are possible, but all suffer from one or more limitations: - -GRASS: ps.map accepts only one raster as background (not possible to tile rasters, unless one patches them, which can be quite difficult for large projects at high resolution); "printing" to a png monitor does help, but scale and legend are missing, and quality is not very good for vector data - -qgis only exports png maps, without scale and legend; I did not find a way of setting output resolution - -gmt is very far from "normal" usage, I believe - -mapserver is apparently more flexible, but I did not try it yet (no .deb package). In addition, many of these programs are not packaged for major distributions (debian, redhat, mandrake...), and this definitely does not help. If I am missing something, I would appreciate your suggestions. I am sure if we could set up a short guide on how to do easy free map printing, this could be useful for other users too.

At Intevation we also came to that conclusion and already explored a couple of other options. My current vision of this is something that what I call "Thuban-MAP-SVG". The design idea is that for the final touch of any map, you will need a very powerful page-layout/vector drawing application. Those applications exist, but usually do not know much about maps. So the idea is to make an interactive geoviewer play nicely together with a genral vector drawing applications. With proprietary software the chances for this to happens is low, because each vendor always has the tendency to try to add more feature to his proprietary product to increase sales. With Free Software on the other hand it is possible to modify both applications and sell a combined solution. So we had a Diplom-Thetis by Markus Rechtien written here at Intevation which implemented this prototype model for Thuban and Skencil (0.7.x). Now Thuban (CVS version) can export a Thuban-Map-SVG, which is fully compliant SVG, but contains more information which Skencil will need to handle the included layers and labels nicely. As Skencil is among the most stable, scriptable and powerful Free Software vector drawing applications, you can then make nice maps. It is just a prototype of and we would welcome more help with Skencil and Thuban, as well as more implementation of the Thuban-MAP-SVG. I believe that it has the possibility to beat the proprietary solutions for printing queues, because it decouples the tasks of map composing and map printing layout. Another usuable predecessor of that Thuban-Skencil(0.7.) solution is the Skencil Geo-Plugin, it will let you place several Shapefile layers on top of each other. Note that Thuban also has a standable vector printing support which is sufficient for many cases. Bernhard -------------- next part -------------- A non-text attachment was scrubbed...
