At this early stage we are still discussing it internally but your request was just yet another one which got us to think that we should continue the discussion in Wiki fashion asap. Drop us a note if you think this makes sense. Initially it was planned to join with universities here in Germany but they are rather slow to react. They do not want to advertise software products because a university has to stay independent which is OK. But what they don't see is that they are already extensively doing just that - promote proprietary software by running courses and educating people in using it. So then we planned to come up with a first short-term certification (just a few weeks of work) around september this year which would involve a rather heavy fee for those of us who can't wait and need to spend money. Because all relevant material is licensed under the GNU/FDL *and* online access to most e-leraning environments is also free (would that be the GNU/FSL - Free Service License?!?) this should be a stable basis to create a free-of-cost appreticeshiop as you have in mind. We get our funding from the commercial lectures (for those who can't wait) that we have in our commercial curricula for years now. Hopefully there will always be enough people who need know-how quick and are willing to pay. We alredy have a lot of e-learning components up and running, that part is technically stable but we still lack an access provider that will not suck us dry if we should be slashdotted. Therfore it is not made public just yet. (Which made us think again on how to convince universities, but now that we are competitors of a sort it will not make things easier). We had quite a few discussions on this topic at the Open Geospatial in Minnesota and most everybody told us to push on to close the gap with some sort of official certification with or without university backup. You can contact Torsten (brassat at geo-consortium.de) or me if you are interested in further details. Best, Arnulf.

Another glitch can be found in the downloadable EULA: http://www.ermapper.com/downloads/down/download_product.aspx?PRODUCT_VERSION_ID=275 In Setion "ECW JPEG 2000 SDK FREE USE LICENSE AGREEMENT" it says: [...] The intent of this license is to allow unlimited decompression and limited compression (500MB per image) of ECW JPEG 2000 images within free or commercial applications. [...] Ont the homepage you find another definiton under "Updated ECW JPEG SDK EULA": http://www.ermapper.com/downloads/download_view.aspx?PRODUCT_VERSION_ID=275 [...] Free GPL style EULA (for non-commercial free software including server based software): * Unlimited decompression * Unlimited compression [...] Before using compression i would therfore strongly recommend to check back and ask them for clarification. Regarding the term "commercial" there is still a lot of midsunderstanding going on - even on this list. Most everybody still says "commercial vs. Free" although it should say "proprietary vs. Free" or "closed vs. Free" depending of the point of view. But what the heck, learning takes time, give people time to understand. Resulting from this confusion of definitons currently ERM does not provide a license for "commercial free software". Besides that i am pretty excited at having them open their licensing agreements to such a far degree. It is really very complicated to do this, especially if beforehand you did provide your software under a closed license (talk to any merited manager and he will be ignorant as a child to what you tell him). You collect all sorts of restrictions on components that have become integral part of your software a long time ago. So i think we should very much appreciate their initiative. To retrospectively GPL (as a verb) a software in european law it additionally requires you to contact every single developer and have her sign an agreement which allows you to do this - tribute to European authorship legislation. > That's really too bad for them, because both issues you mention can be > resolved pretty easily: not changing the format itself can be achieved > with a trademark enforcement and the same trademark can avoid the > distribution of modified ECW software (since I guess that ER is afraid > that somebody distributes a modified sdk that doesn't work well and they > risk losing their credibility).

I don't much about available shareware GIS, but I rather recommend to build a Enterprise GIS on Free GIS Software. In fact 'the' Enterprise GIS does not exist. GIS is stongly component oriented. Enterpise-Level components for Windows are e.g.: UMN MapServer, PostGIS, deegree, uDIG. The question whether it is possible or not is already answered ;-) There are a number of companies delivering such solutions for many years.

Hi Robert, You may be interested in a paper I had published in the SECOND INTERNATIONAL SYMPOSIUM ON GIS/SPATIAL ANALYSES IN FISHERY AND AQUATIC SCIENCES. See http://www.esl.co.jp/Sympo/2nd/pdf/contents.pdf which lists the paper by Brent Wood on constructing a Fishery GIS from free/Open Source components. (This was not formally presented at the symposium, but arose from another paper I presented, which used OS GIS tools & generated sufficient interest to have the second paper written for the proceedings) I have also given presentations on standards based GIS, where the various functional components of a corporate GIS are different (but interoperable) GIS packges. The focus was on not buying into proprietary systems, but ensuring that the components of a corporate GIS adhered to appropriate standards (eg: OGC) so the user could choose the most appropriate package for their needs out of the available commercial or Open Source offerings to build a customised suite of GIS tools to best meet their needs. I guess such a suite could equate to an enterprise GIS. > I am having trouble finding literature on this topic. > > Can anybody out there help me locate published studies, reports, > presentations, books, conference papers... > Cheers, Brent Wood From cresques at gmail.com Thu Jul 7 02:15:25 2005 From: cresques at gmail.com (Cresques) Date: Thu, 07 Jul 2005 02:15:25 +0200 Subject: [Freegis-list] Thesis on Enterprise GIS In-Reply-To: <20050706233404.57255.qmail@web33201.mail.mud.yahoo.com> References: <20050706233404.57255.qmail@web33201.mail.mud.yahoo.com> Message-ID: <42CC741D.2030004@gmail.com> Hi, Brent Wood wrote: >--- "Brundage, Robert G" wrote: > > > >>Hello Group: >> >>I am interested in doing my thesis on whether it is possible to compose an >>'Enterprise GIS' scenario using shareware software on a Windows computer >>network. >> >> > >Hi Robert, > >You may be interested in a paper I had published in the SECOND INTERNATIONAL >SYMPOSIUM ON GIS/SPATIAL ANALYSES IN FISHERY AND AQUATIC SCIENCES. > >See http://www.esl.co.jp/Sympo/2nd/pdf/contents.pdf which lists the paper by >Brent Wood on constructing a Fishery GIS from free/Open Source components. >(This was not formally presented at the symposium, but arose from another paper >I presented, which used OS GIS tools & generated sufficient interest to have >the second paper written for the proceedings) > > > I'm interested on this paper.

Thought I'd provide a quick rundown on the licenses available for the ECW JPEG 2000 SDK for the benefit of this thread. The SDK is covered under three licenses: "Free Use", "Public Use", and "Commercial Use". None of these licenses either does, or is currently intended to conform exactly to the GPL or BSD licenses, or to the requirements of free software. We refer to the Public Use license as a "GPL-style" license because it contains a copyleft restriction, and imposes no other very significant requirements on use or distribution. There seems to be an implication in the SDK EULA that the Public Use license can only apply to free (as in beer) software. I will review this point and get back to you. It is true that we have mainly anticipated the Public Use license applying to the development of non-commercial software. We refer to the Free Use license as a "BSD-style" license because you can do to a large extent what you want with the code (no copyleft). The only restrictions on the use of this code are as follows: - size of input datasets for ECW and JPEG 2000 compression tasks is limited to 500MB - development of "server software" components is prohibited These restrictions are in place for business reasons. Note: they do not apply to the Public Use license. The Commercial Use license is functionally the same as the Free Use license, except with the restriction on the size of input datasets for ECW and JPEG 2000 compression tasks removed. The other "value added" in an instance of the Commercial Use license is packaged support. About the issues surrounding modification of the ECW format and redistribution of modified codesets: I'll review the wording in the EULA and possibly suggest changes may be needed (thanks for the input on trademark enforcement, Stefano). I can tell you now that we care more about the issue of the integrity of the ECW format (which ends up being a sizable chunk of the ER Mapper support burden) than the redistribution rights. The latter is mainly an exercise in image protection. Our ultimate goal with the licensing is to find free licenses for the SDK which are in line with our business needs and with common OSS practice. We're slowly getting closer to that :-) Hope this clears up some of the confusion in this space. Feel free to add questions and criticism. We are open to new ideas on the licensing. cheers -- Tom Lynch Development, ER Mapper Phone: +61 8 93882900 Fax: +61 8 93882901 Email: tom.lynch at ermapper.com Web: http://www.ermapper.com Forums: http://forum.ermapper.com From tflynch at gmail.com Thu Jul 7 02:34:27 2005 From: tflynch at gmail.com (Tom Lynch) Date: Thu, 7 Jul 2005 08:34:27 +0800 Subject: [Freegis-list] Re: free ecw?

There most OWS are non-soap, but either KVP (Keyword Value Pair encoding = CGI style) or XML encoded. During the last years the discussion about usage of SOAP and corresponding standards took place at almost all meetings of OGC and there was no general answer found if using SOAP makes sense or is a necessity for OWS. So there is now a slow transition towards these standards, the newer OWS specification such as Catalog Serivce now include a SOAP binding, so it is possible to implement them with or wittout SOAP. Similar bindings will be developed during the next months and years for most/all OWS. Hope this is the answer you are looking for. regards Markus Christopher Jon Jursa schrieb: >Hello, > >I am performing research in geospatial web services.

I have not read the Autodesk license, but this sounds like the same thing the BBN legal people made us do with the OpenMap license. The issue they could not figure out was how to be sure that they would receive notice of mods people made. Assume developer X makes some mods and releases them. The question is, how would BBN be sure to find the mods made by X if they just randomly show up on the net. The answer, to them was, make X also provide the mods back to BBN, thus ensuring they are informed. I think in general, for most FOSS projects, X would make the mods known to the originators since otherwise the mods themselves are less likely to get back into the main release tree.

Mark, I believe the OGR NTF driver supports treating a directory of NTF files as a single dataset. So, dump all your address point files into one subdirectory, and then use the subdirectory name as the input for ogr2ogr. It should create one merged Mapinfo dataset. BTW, I'm not too sure what version of ogr2ogr you are using, but a fairly recent one is pre-built as part of the FWTools kit at: http://fwtools.maptools.org/ Best regards, -- ---------------------------------------+-------------------------------------- I set the clouds in motion - turn up | Frank Warmerdam, warmerdam at pobox.com light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | Geospatial Programmer for Rent From dipankarcpatnaik at gmail.com Thu Jul 14 11:15:04 2005 From: dipankarcpatnaik at gmail.com (dipankar c.patnaik) Date: Thu, 14 Jul 2005 14:45:04 +0530 Subject: [Freegis-list] shpfiles import into SPRING Message-ID: Hi all please tell me as to how do I import a shapeflie fom arc view or an arcinfo coverage into the SPRING software this is very urgent, please reply soon and help me i have been having problems with the category definition while importing and as the help files are in Spanish or portugese, i am at a loss to understand em and solve it on my own alsoe please tell me the sites where from I could get some informative materials about SPring usages thank you bye for now take care dipankar India From jan at intevation.de Thu Jul 14 11:34:19 2005 From: jan at intevation.de (Jan-Oliver Wagner) Date: Thu, 14 Jul 2005 11:34:19 +0200 Subject: [Freegis-list] shpfiles import into SPRING In-Reply-To: References: Message-ID: <20050714093419.GB22110@intevation.de> On Thu, Jul 14, 2005 at 02:45:04PM +0530, dipankar c.patnaik wrote: > please tell me as to how do I import a shapeflie fom arc view or an > arcinfo coverage into the SPRING software > this is very urgent, > please reply soon and help me > i have been having problems with the category definition while > importing and as the help files are in Spanish or portugese, i am at a > loss to understand em and solve it on my own > alsoe please tell me the sites where from I could get some informative > materials about SPring usages For the archive: Spring is (still) no Free Software.

So far, most datasets are Public Domain or some BSDish license, some are GNU GPL. Some CC are interesting as well. For FreeGIS, this remains an open discussion. Of course some things are clear, such as: limited use or no right to distribute renders a dataset non-free. I'd love also to see a license discussion come up. Many projects are looking for better licenses for their geodata. GNU GPL is definitly for Software and of limited applicability for geodata. A more suitable license with the same base idea as GNU GPL is something I am personally interested in.

A couple of points on this: The licence used by Land Information New Zealand (LINZ, see "Licence Agreement" link at http://www.linz.govt.nz/rcs/linz/pub/web/root/core/Topography/TopographicData/topodtabase/index.jsp ) seems similar to the BSD licence. Once purchased ($2500NZ), you can just about do what you like with it except hold LINZ liable. You can sell/give/rework as you desire. Overall, I like it. I believe (but haven't checked recently) that much of the Australian and Canadian government data is under a similar licence. I'm sure someone here knows the US situation better than me, though I do get a great deal of useful data from various US sources. However, the LSLIFF format LINZ supply the data in is pretty useless without a reformatter. Local distributors of commercial GIS software purchase the data, reformat for their software & resell as a commercial product. So the LINZ freely redistributable data has not really been freely available. I have recently obtained a free copy of the LSLIFF data & have it converted to shape files, so it can be given away & used wherever. (I'd like to set up a mapserver with a PostGIS database, but 'tis another story...) Third+ hand recipients/users of the data must still be covered by the LINZ copyright & disclaimer, as well as any licences required by the intermediaries who may have added some value, and can therefore apply a commercial licence to their version of the data. Up until my "free as in speech & beer" version, the only useable versions of this data were covered by restrictive commercial licences (on top of the LINZ copyright & disclaimer) and commercial prices, (justified as being for a range of supposedly added value). This at least is one example of a national dataset of vector (& ortho's) being provided under a pretty facilitative licence. Also worth perusing if this topic is gonna be discussed, is a book covering this topic, from a different perspective, but with some interesting points, 'tis at http://www.nap.edu/openbook/0309092671/html/4.html I understand data licencing was also a topic at the GeoBusiness Conference 2000, regarding European datasets, but this was mentioned in passing, I don't know relevent/useful it was.

One uncertainty remains: what are in fact the rights of a third party receiving the data. Maybe an official inquiry to LINZ could clarify that?

To complement this point, some information about the Geobase initiative (http://www.geobase.ca) follows. "GeoBase is a federal, provincial and territorial government initiative that is overseen by the Canadian Council on Geomatics (CCOG). It is undertaken to ensure the provision of, and access to, a common, up-to-date and maintained base of quality geospatial data for all of Canada. Through the GeoBase portal, users with an interest in the field of geomatics have access to quality geospatial information at no cost and with unrestricted use. GeoBase responds to Canadians' requests for access to data at no cost to users. It is built on partnerships and innovative technology. By working together, multiple levels of government are increasing their efficiency in collecting and maintaining geospatial data. This also reduces duplication of efforts among agencies." "GeoBase is a key component of the Canadian Geospatial Data Infrastructure that has been promoted and facilitated through GeoConnections. The GeoConnections program has provided significant funding for the preparation of, and accessibility to, GeoBase data and the GeoBase portal complies with GeoConnections' vision and principles." The text of the license under which data are released can be found at: http://www.geobase.ca/geobase/en/licence.jsp In France, free software seem to be more and more considered as reliable solutions especially for webmapping applications. Nevertheless, the deployment of such applications is hindered by licensing conditions often applied to data ... The definition of a free geodata license has thus been undergone by some geomaticians. This license is named PGL, which stands for Public Geodata License: "In the french context, very few geographic datas are freely available: many of them came from National Imaging and Mapping Agency or from US Geological Survey... Even in the most advanced public experiences, licenses generally prohibits free web uses and downloads. According to french laws, the producer of datas may be prosecuted if an accident happens by a data-related way. Lawyers haven't experienced many trials yet, but they all think that metadatas may legally secure the producers either the users. Nowadays, networking and interoperabilty improvements, like Web Map Services, turns into new GIS architectures. In the same times, public, private, and social needs for geographic datas increase. So why not building with a specific license for geodatas the same benefits than the GPL license for software ? Cooperative GIS initiatives are now much easier, so they are much numerous. A specific license could help geomaticians, enterprises and administrations to trust into massive-GIS projects, and to contribute in the same ways than free softwares developpers do since many years. Because access to public geographic datas is not only a french problem, such a license may help many geomaticians worldwide. This is the idea of the "PGL", Public Geodata License (In french, DGL, which mean "Donn?es g?ographiques Libres". A "beta version" is available for improvements (at http://sig.cwiter.org). A first release is projected for the end of year 2003. A short abstract could be: Public Geodatas License is equal to GPL-like license plus metadatas. Contributions welcome !" (source: http://2003.rencontresmondiales.org/program/view_topic.php?topic_id=22#lecture99) A first version of the text of the PGL license can be found at: http://sig.cwriter.org/index.php/PGL/PGL+version+0.1/contenu . Unfortunately, the text is only in French but my comprehension of it is that the sentence "Public Geodatas License is equal to GPL-like license plus metadatas" summarize very well its content. Th.

( I recall a while back someone complaining of GML?s verbosity, and others replying that?s ok, you can always gZip it ) Our case: my people are testing all sorts of permutations of clients seeking data from WMS and WFS, and are making a series of Excel charts documenting what happens in each case, varying the number of simultaneous users (they generate multiple user threads to attack the server), the server characteristics (RAM, O.S.), and the data size as retrieved. Among other things they are finding that retrieving a several megabyte GML as generated by MapServer?s WFS, is not possible under the generous 10 minute timeout limitation with client and server on machines in the same laboratory and connected via 100 Mbit switch. However, when they fast-Zip a 100+ MB file (manually) they find that it is reduced to about 5MB. So it would seem to be a good idea for the server to do this, under certain circumstances. So, who is doing this? Is there code available? How are we on the issue of GML compression? Or on the occasional use of GML-binary?

That's why OpenOffice's format is XML-inside-zip-archive. gzip compression for transport should be transparently handled by the web server. It is specified in HTTP 1.1 at least; see e.g. mod_gzip for Apache. The point is that the http *client* should 1) advertise gzip capabilities when sending requests, using 'Accept-encoding: gzip' in the headers sent along the GET/POST request and 2) handle decompression. Modern browsers do. I don't know about current WFS/WMS clients. Do try to sniff the connection to find out. Hope this helps. Daniel.

Or on the occasional use of GML-binary? Yes, we wrestled with this in GeoServer for awhile. Some said that it should always just be the http server that you set up in front of your WFS to deal with. Like Daniel says, Apache is easily configured to do this, and then you can use a connector to tomcat, or whatever servlet container you like. Browsers will transparently handle the requests. And then wfs clients could also be coded to do it at the level of http transport. In GeoServer we also support gzipped gml2 as an output format (use 'GML2-GZIP' for the outputformat param), and the gml production will go through a gzipping output stream. Some thought it might be useful, so it's just an extra format. No one's asked about this for awhile, but I think it should work. We no longer advertise it in the capabilities document, because it breaks the CITE conformance tests, which is a bit annoying to say the least. I think the schema can support additional output formats, but CITE only recognizes a certain subset. Or at least that's what I recall, it's been awhile. Gabriel Roldan (cced) was the author of the capability, and he also looked into bxml encodings for GeoServer. If I recall correctly it wasn't as big of a performance win as we were hoping. He may be able to tell you more. But if MapServer is taking too long to generate the GML file, then I don't think gzipping on the fly will help - I assume your networks are fast and it's not the transport, but the making of the GML file.

Just at the lower layer of functionality, that is, the codec itself, not a JAXP adapter. We based our work on the same dataset that CubeWerx used for demostration of its C based parser, though we wanted to go far than that parser, since it is very limited and does not complains with the BXML discussion paper in the sense that is unable to handle different char encodings. So we used java nio classes and implemented our codec. Then found that the gain in parsing a bxml stream is considerable, as well as the reduction in content size. But encoding time isn't far better than using jaxp, since almost 80% the time is consumed by the caracter encoding classes. Anyway, I'm just hoping to find the time to continue the development of the parser and integrate it with the geotools gml stuff to support encoding well known gml elements (mostly geometries) in an optimal packagins (foe example, encoding the coordinates as a real array of doubles or float instead of a long string), and may be finding a way of optimizing characted encoding at least for the most common used ones. My impression: bxml would be a huge gain for WFS inter-communication, and my testings shows that at least at the extent I was able to test, the gain in bxml production is not so considerable, but in parsing a bxml encoded stram will be. gabriel.

Message-ID: <42E8B170.5090207@ekoi.lt> Dear Colleagues, Sorry for (possible) cross-posting, but I hope that this information (on behalf of the Baltic Sea Regional Project - BSRP) will be useful for at least some of you. As one of the tasks specified in the BSRP GIS Coordination Center work plan, a new Baltic GIS portal was recently launched at the Institute of Ecology of Vilnius University. The internet link (temporarily) is this: http://www.ekoi.lt/gis . New GIS data layers and postings are being uploaded almost every day, so don't forget to periodically check it later. All data available for download so far is FREE for registered users. The ambition of this service is to integrate the GIS/RS - related information, strengthen the community of GIS users and process/distribute public domain databases covering the Baltic Sea drainage basin, thus providing technical assistance to HELCOM, ICES and, if necessary, EEA. I hope you will find this service useful and contribute to its further development with your advice, postings and information. We would also appreciate if you publicize this service among your colleagues.

I'm working on writing some programs to analyse raster datafiles. So far, I have used gdal to load up the rasters. In order to carry out our analyses, we have downloaded from an Oracle Spatial database, the locations and atributes of a number of polygons, which have been subsequently rasterised to cover the same region and cell spacing as the rasters which we want to analyse. This works, and works pretty well. However, I would like to automatise that, because the data in the database changes every so often. Ideally, I would like to just point the program to the database and let it get the data, generate the vectors and carry out the pixel selection. I'm not familiarised with the libraries that might be used to accomplish this. I would appreciate views on how to accomplish this (in its totality or even in parts!), what free sofware options are available, etc. Many thanks for your time, Jose From fwarmerdam at gmail.com Fri Jul 29 15:13:15 2005 From: fwarmerdam at gmail.com (Frank Warmerdam) Date: Fri, 29 Jul 2005 09:13:15 -0400 Subject: [Freegis-list] Rasters, Vectors and spatial databases In-Reply-To: <91d218430507290506653dc98@mail.gmail.com> References: <91d218430507290506653dc98@mail.gmail.com> Message-ID: <931f8ea905072906136ac143fe@mail.gmail.com> On 7/29/05, Jose Gomez-Dans wrote: > Hi! > I'm working on writing some programs to analyse raster datafiles.

Either at the commandline with ogr2ogr, using the C++ API or perhaps from Python. I'm not sure what you have been using to rasterize he polygons so far, but I do know of folks doing this sort of thing with MapServer. The whole process could also be automated in GRASS which includes GDAL raster access and OGR vector access as well as good polygon rasterization for masking, and sophisticated sorts of raster analysis. You might need to be somewhat handy with shell scripting to automate it in GRASS. A variety of other options also exist of course.

Has versions for Linux/Windows/OSX. It has a plugin for displaying point data stored in a text file, you enter the delimiter character & which columns have the X & Y data & it is a layer on your map. This plugin is supplied with the standard QGIS install. If you want to use a database to store the data instead of text files, it also supports PostGIS.
