[OSGeo-Discuss] designing databases, organizing data formats to work with open source and proprietary GIS
Karsten,Interoperability with ESRI GeoDatabases (SQL, not file) have their difficulties but they aren't insurmountable.To address such interop one must make clear distinctions at differing tiers.The first is that the chosen "storage format" is the "native" one for the chosen database product: That is Oracle's SDO_Geometry, Microsoft's geomery/geography, or PostgreSQL/PostGIS's geometry/geography. Interop with ESRI's ST_Geometry is possible butwidespread support across different proprietary and open source product is problematic.The second is the database data model. One should not use ESRI's GeoDatabase Design Tool as the ONLY tool for defining the data model.Use it, yes, for the ESRI side of the data model/access question, but additionally, one should use a horizontal market data modelling tool(like Enterprise Architect which supports ArcGIS data model xml) to QA the model produced by the ESRI tool, to specify more open datatypes, to add additional documentation (that most ESRI customer shops do in Word documents by hand), and to forward engineer those components of the model that ESRI rather likes to keep to itself and not share with others (eg constraints, lookup tables/coded domains, foreign keys etc).The final aspect is ensuring that ESRI software can do what it believes it needs to be able to do if you are using topological rules,versioning etc.In essence the activities are: 1. Define the model so that it can serve an intelligent data to multiple clients independent of vendor. This is best practice data management fully in line with database theory.2. Then "configure" the ESRI interface (treat ArcSDE as a JDBC interface for ESRI clients) so that it can use the model as if it created it itself.I have had success with this in the past. It isn't rocket science though the latter can require a bit of clever thinking.regardsSimon Original Message Subject: [OSGeo-Discuss] designing databases, organizing data formats to work with open source and proprietary GIS Date: Wed, 10 Aug 2011 10:42:55 -0700 From: karsten vennemann Reply-To: OSGeo Discussions To: Hi all, in the near future I will have the opportunity to help design databases, decide on data formats (files data) for an international organization that wishes to be able to use both proprietary and open source based systems, mostly in web mapping solution but also possibly on the desktop.

Re: [OSGeo-Discuss] Re: Board Nomination - Gérald Fenoy
Dear all, Sorry for so late reply get some painful "hollidays issue" ... First, I want to thank Jeff for this nomination to OSGeo board of directors. Working for 7 years in web GIS development, OSGeo shown me the way to go. Indeed, I've always find, through OSGeo, an answer to my questions. Sometimes it was about searching for a solution to a specific problem, sometimes it was about the way to use specific software, sometimes it was about problem occuring using software. Anytime I had to ask, I can find quickly a solution by asking people from OSGeo all over the world using various kind of communication media. There is always somebody wake up at OSGeo, you can reach us. This is an impressive help for everybody which is using the software or just want to know about software solution for the problem they face off. In 2006 I got the chance to join the event where most of the people involved from all over the world in Free and Open Source Software four GIS was present. Then, I always join the event thinking that it is key event to learn about GIS innovative solutions and meet people which make this solutions possible. OSGeo is spreading knowledge by providing more and more hight quality material to learn on your own how to use solutions. You came to OSGeo with questions and you find your answer but also more questions with answers... new ideas. As OSGeo help me so much by providing solutions and materials, it sounds obvious to me to promote it everywhere I go. Promotion, including translation, training sessions, workshops, talks or simple discussion.

David, Thank you very much for this nomination. It is a great honor to be so well respected by you. It is also with much regret that I decline your offer. I really had intended on accepting this, but after thinking about the extra responsibility this position would require, I realized I would be spreading myself too thin,feeling a bit out of my element, and regret later not being able to serve OSGeo as well as I wanted to. I would also be possibly depriving others with more energy and will from making their impact. We have a bright and very energetic group of nominees, and I'm looking forward to seeing many of them, including David serve on our board.

[OSGeo-Discuss] Board Candidate's Statement: David Bitner
Thank you very much for your consideration to become a member of the OSGeo Board. I have been involved with the community that came to be OSGeo since working on the planning committee for The MapServer Users Meeting in Minnesota in 2005 (the immediate predecessor to the FOSS4G conference) and helping to found the Twin Cities MapServer Users Group (now a local OSGeo chapter) with the others who were involved in planning that conference. I have been the OSGeo Public Geospatial Data Committee chair since 2007. It is my experience with that committee that leads me to want to work more strategically with the OSGeo Board. The Geospatial Data Committee has been largely ineffective and dormant throughout it's existence. The importance of geodata has always been recognized as a critical part of OSGeo leading to the formation of this committee alongside the founding of OSGeo. There have been a number of false starts at creating a central catalog on OSGeo resources. There have been loosely affiliated efforts such as the FlightGear Scenery Project and Open Aerial Map take 1. The only truly successful geodata project coming directly out of OSGeo has been led not by the Geospatial Data Committee, but by the Education Committee with the set of data pulled together for educational usage. I don't see the inactivity of this group as a failure, but more as a recognition that while an absolutely critical component of using OSGeo products, there simply is not the energy within our organization to tackle everything that we would like. I have been very excited to see the partnerships and MOUs that have been coming down the pipe recently. One critical way that we can help to prevent spreading our resources too thin that we are ineffective is to work with other like minded groups. The partnerships that we have with the OGC and now in the works with several educational groups is a great way for us to leverage the strengths and particular audiences that these other groups bring in. In particular, I think that there are significant opportunities for OSGeo to support and partner with domain-specific groups. Having worked significantly in the humanitarian/emergency response world through my involvement with the Sahana Software Foundation, OSGeo software is being heavily used throughout this domain by people and projects like Sahana, the Humanitarian OpenStreetMap Team, CrisisMappers, and Crisis Commons. By supporting these groups through cooperation we can help more people in this domain become aware of and use OSGeo software (and correspondingly can make more OSGeo folks aware of opportunities that they may have to support these humanitarian efforts). I see additional opportunities in finding ways to work with groups that have traditionally been stovepiped. In particular there is much work being done in domains such as public transportation, aviation noise, city/county public information, large government or organization SDI. Whether through creating MOUs or informal partnerships with groups that are already supporting these domains or extending our local chapter concept to create domain users groups with mailing lists this is the key direction that I would like to push for OSGeo. Again, thank you very much for your consideration and I look forward to seeing many of you in Denver!

Re: [OSGeo-Discuss] designing databases, organizing data formats to work with open source and proprietary GIS
All, esp Karsten, I wonder if you've given consideration to the feasibility of a solution based on web services; If feasible, this could bypass the issue you correctly raise re "what data storage solution you would recommend ", since the function of the service wd be to return data in one of the standard/common formats regardless of the origin. It's a non-trivial effort to design a suitable API, but such an implementation cd provide the data to suitably-connected desktop applications, as well as to conventional browsers, of course AS On Wed, Aug 10, 2011 at 2:19 PM, Mr. Puneet Kishor wrote: > Karsten, > > On Aug 10, 2011, at 11:12 PM, karsten vennemann wrote: > > > Hi all, > > > > in the near future I will have the opportunity to help design databases, > decide on data formats (files data) for an international organization that > wishes to be able to use both proprietary and open source based systems, > mostly in web mapping solution but also possibly on the desktop.

Re: [OSGeo-Discuss] designing databases,organizing data formats to work with open source and proprie
Karsten, I've not tried it myself, but this Q&A indicates that with 10.1 you can read directly from PostGIS. Although not entirely clear, simple editing may be available as well but not "complex spatial data and transactions ... ( i.e., topology, rasters, networks, replication, and archiving)." http://events.esri.com/uc/QandA/index.cfm?fuseaction=answer&conferenceId=DD02CFE7-1422-2418-7F271831F47A7A31&questionId=3949 Depending on particulars, PostGIS data in ESRI products may be totally trivial.

[OSGeo-Discuss] C# DotSpatial Library Workshop at FOSS4G
Hey all, Just a quick invitation to sign up for our C# DotSpatial Library workshop at FOSS4G. We're excited to show you all what the DotNet/DotSpatial group has accomplished in the last year, and for any of you who like to code in C# (or want to learn) we hope you'll enjoy this workshop. By the end of the workshop you will be fully equipped to design and deploy a full GIS desktop application. Tutorials include working with projections, using the map/legend controls, working with vector/raster data types, etc. Also, although the focus is on C#, we will also have materials available to do the tutorials in VB.NET. - Dan P.S. For those of you who are unfamiliar with DotSpatial: it's goal is to bring together all the best .NET based FOSS4g tools into a single well-integrated programming suite as an alternative to ArcObjects for custom GIS software/tool development. P.P.S. A DotSpatial OSGeo project incubation application is being prepared, so this workshop will also be used to introduce the project in general for that purpose. -- Daniel P.

[OSGeo-Discuss] designing databases, organizing data formats to work with open source and proprietary GIS
Hi all, in the near future I will have the opportunity to help design databases, decide on data formats (files data) for an international organization that wishes to be able to use both proprietary and open source based systems, mostly in web mapping solution but also possibly on the desktop. The task will be to design and organize the data stores in a way that both types of systems - open source (e.g. MapServer, OpenLayers) and proprietary systems (ESRI Arc Server) can use them well, and along the way to try to avoid too much data duplication (having to store data in multiple formats just to make them accessible) . This sounds to like a exiting & useful, fun task, but given the limitations of both systems (regarding input data that might not work out of the box- namely file Geodatabases in open source solutions, and PostGIS data in ESRI products) might be not totally trivial ;) I was wondering if anybody has done work on this, has implemented systems facing the same issues or knows of projects or reports that have been dealing with similar issues. Also I anybody has comments about what data storage solution you would recommend and comments about the pro and cons of certain storage designs please send it to the list. Looking forward to hear what other have come up with.

The "A Complete Web Mapping > Stack" looks really good... as does "GeoNetwork for dummies, or how to > setup and use an SDI in 3 hours"... From your past conversations it sounds like you need some kind of "stack" focused session that covers several layers of tools, so I think you're on track with that one. You probably can't go wrong unless you chose a more advanced topic or one that is looking only at one piece of the larger architecture (like PostGIS). Just a thought, hope you can make it!

Re: [OSGeo-Discuss] Workshops filling up...
Tyler - I'm having a bit of trouble deciding what to choose! I'm going to choose today, I think... One quick question - I'm thinking the Introduction to Geospatial Opensource would be the best for me... It appears that I can pay $150 for the full day event ... is that true? Other than that, there are so many to choose from - Geoserver, Geomoose, PostGIS, Mapfish, and Geomajas. The "A Complete Web Mapping Stack" looks really good... as does "GeoNetwork for dummies, or how to setup and use an SDI in 3 hours"... Based on what we discussed, what would you suggest if I were to sign up for 1 or 2 workshops?

RE: [OSGeo-Discuss] Candidate's Thoughts on OSGeo
First of all impressive list of nominations. My hope is that all the would be directors of OSGeo Board from which ever background they come, give due importance to the education efforts. I believe this will be very important for the long term. The students of today will be the GIS leaders and decision makers of tomorrow. Having focus on education is key for global perspective, building collaboration, supporting local chapters and providing strategic vision for OSGeo for the future.
