Re: [OSGeo-Discuss] Inquiry: Help please!
Hi, Sid! I would like to develop an algorithm that uses remote geographic sensing data to automatically identify, highlight, and measure rooftops and buildings surfaces and contours using Geospatial data. My preference is to overlay the results on one of the existing map providers such as Google Earth/maps or Bing . My aim is to get the following outputs from the proposed model: - Accurately highlighted and identified rooftops on Google maps (using geo sensing data, elevation? and - Property Address or GPS coordinate. - Surface and square footage available for solar power generation including the position of the property(N-S or E-W). At the exact surface of the south facing portion of the roof. - Integrate sun tool in google maps to calculate shading for each building. - Total surface/square footage of the roof. I would appreciate your guidance on the following: - Any individual developers or companies active in this area who would be willing to undertake this challenge - View on technical do-ability of the project… - What free geospatial data is available/needed to build the model and who the providers are? (I understand that US cleared higher resolution imagery for domestic ) - An idea about the overall cost for such a model. Best regards, Sid Just want to mention two things: 1) Building outlines are available for some locations in both commercial maps (Google and Bing, for instance). In OpenStreetMap, if buildings have not been mapped for a specific area you're interested in, you might be able to get local mappers to do it. (Of course, the building outlines obtained that way may not be accurate. Many times, the building outline is simplified from the actual building as it's only needed to indicate, there is / was a building here, e.g. for rescue workers looking for survivors after a natural disaster.) 2) If you use satellite imagery (or possibly low-elevation imagery if you have accurate info on the camera path and orientation), then the shadows cast by buildings can be used to estimate their height. A very brief web search turns up a fair number of papers on this -- just one example, with references to earlier work that may be more relevant: http://www.asprs.org/a/publications/pers/98journal/january/1998_jan_35-44.pdf -- Pat ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss
Re: [OSGeo-Discuss] [Election 2014] Nomination of Vivien Deparday
+1 for this nomination. I have worked with him in InaSafe/OSM related activities here in Sri Lanka. He is extremely energetic, never get tired when he is doing OSM/GeoNode work and very importantly advocates open source initiatives in difficult situations. He has excellent capacity to link different people with OS-Geo projects. Nimalika On Fri, Aug 1, 2014 at 10:22 AM, Paolo Corti pco...@gmail.com wrote: I definitely second this nomination.

Thanks for adding this to the Board agenda Eli (your draft text looks good), I agree it makes sense to keep Charter Members aware of this, even though it is unlikely to happen. -jeff On 2014-08-02 1:04 AM, Eli Adam wrote: When I approach someone who I want to nominate for charter membership, I sometimes explain that their only real functional role in OSGeo as charter members is to be aware of and respond to hostile takeover attempts of OSGeo or OSGeo funds/assets. And to serve as the pool from which board members are drawn. As unlikely as hostile takeover attempts are, recognizing and responding to that is the only thing that charter members can do that non-charter members can not (other than serving on the board). In most cases, individuals have already long been doing and can continue to do all the positive actions and attributes listed, http://wiki.osgeo.org/wiki/Membership_Process#Positive_Attributes I get some are you serious responses for approaching people this way but do think it is worth reminding people of this important (although unlikely and hopefully never needed) role. I think that the process is self-actualizing, i.e. since we have a policy in place that prevents or guards against hostile takeover attempts, there will be no attempts since it would not work. Since we have a maybe somewhat cumbersome process to guard against something that will never happen since the process exists, it makes it look like the process is entirely unnecessary and a pointless headache. I think that this function is sufficiently obscure that the board should consider adding it to the positive attributes sought from charter members and have taken the liberty of putting it on the board agenda [1]. If the board has time and so desires, they may undertake this. I'm not trying to ignore the important role that charter members play by serving as the pool of potential board members, it is just that most charter members will never serve on the board but all charter members can and should actively be aware of and respond to potential hostile takeover attempts (which once again are unlikely and will probably never happen so long as we have effective policies in place to prevent them).

Re: [OSGeo-Discuss] [Election 2014] Nominations finish tomorrow!!
Dear all Charter members, this method of electing Charter members looks good to experiment with. Yes No and Abstain.. I have seen quite a few mails supporting candidates. As a Charter member I go by the recommendations, as it is impossible to really know each 'charter member to be elected'. But.. 'No and Abstain', if these are going to be used then some explanation is also due, before the election process begins. Because personally I believe, many of us will vote 'YES' (hopefully) to every 'charter member to be elected'. So it is likely they may find a place on the charter inspite of an 'Abstain or even a NO' by some who know them. I hope many of the charter members view this as a genuine predicament..

The reason for the bylaws is to avoid hostile take-over. Admittedly very unlikely, but still possible. So we have changed our voting processes to try and be as inclusive as possible, basically aiming to ensure that everyone who is interested, and actively contributing toward OSGeo should be voted in for charter membership.

Perhaps I am the only one not aware of the new election rules. Can you clarify please. Venka Hi Venka, thanks for raising the question. On previous years the Board allocated a number of seats and if there were more nominations than seats then elections were conducted, so some people could not get the membership if they were at the end of the ranking. Other years no election was needed because there were less nominations than seats, so everyone was automatically accepted. As was discussed in June[1], a new procedure was designed[2]. On this new procedure, there is no limit of seats for new charter members, the nominations are carried as every year but instead of having a number of seats, we will have a different criteria for accepting new members. Another difference is that instead of voting by e-mail, with 180 members, we will use an electronic voting system. For every nominee, current Charter Members will have to decide say Yes, No or Abstain for their acceptance. This way we assure that supported nominees are accepted. The criteria will be: - The nominee needs to have more Yes than No - The nominee needs to have more than 5% of Yes of voting members. And then we arrive to one VERY important point in my opinion. For me, the +1 and seconds on discuss mean a LOT, because maybe a I don't know the nominee, but I know many of the nominators and seconders, and I trust their criteria so they add points for me to vote a *Yes* instead of an *Abstain*. There are more than 60 nominations, so checking every nominee discussion will take a while for Charter Members, but it's a very important excercise to be responsible on our vote on who will be accepted. Sorry for the long mail, I hope it makes sense!!

[OSGeo-Discuss] [Election 2014] Nomination period finished
Hi all Nomination period for the OSGeo Charter Members elections have finished. I've extended a grace period of 12 hours but we can't wait more. So I'm really sorry for those that haven't confirmed their nominations. Doing this process in July/August is not the best time to assure most of people are available. For the next year we should start in May more or less. That's all our fault as a Board, and more prominently mine for non being more proactive in May, but we preferred to have a good discussion on the process on June instead of deferring it for the next year. Anyway, we have more than 60 excellent nominees[1], more than any other year[2]. Today I'll finish the set up of the electronic voting system that will send an e-mail to every charter member (using the address provided to the Charter Members mailing list) with a personal link to access to the voting system. If you have changed your mail recently, please contact us (c...@osgeo.org) to update it properly. Nominees, check your data on the wiki page[2] and if you have any amendment sent it privately to us so we'll correct it ASAP. It's been an intense couple of weeks, I haven't sent so many mails before and wrote to so many people. Thank you all for your patience and good luck to everyone with the elections.
