so so we're in Germany at
the point than others 7
seconds that is the case so it's
not exactly half the perfect so this giving next presentation on the and led administration communities profits from open source OK yes thank you for having me here and my name is of Castilla work to spatial and it was during that it's president and I'm all about open source open data and open standards and how did I end up in the land administration JDiff was just asking me and I end up there because somebody from UN Habitat office Oscar Athena us from the OGC where they could have software from the Open standards guys to use as open source so there were a little confused and she's all walk over to that guy and he will tell you and that's how I ended up on land
administration which is really interesting because in the past 4 years I have learned enormously because I'm German and I live in Germany for cadastral systems in Germany and we have like a precision of several mm which is not good should be better and every piece of land is old by somebody somebody construct something on it and then you can hire it you can live there you have tenure security and I'm really happy that you give this presentation because they don't have to repeat all of this so I what am I going to talk about that
lentil network Introduction to STD the social 10 you're domain model then assume online architectures software prototype and Demo server the positive impact of open source and future development so sold the bill
and to network is an alliance of regional and national partners want to copy contribute to poverty alleviation through land reform improved land management and security of tenure I have no idea how many members it is by now I think 50 or more so it's pretty big organization but a very loose 1 so you don't pay anything you don't you sign a memorandum of understanding understanding and always dual the organization and g this partner is a member of of this network and on UN Habitat through GOTO works with partners including civil society organizations and professional bodies so I'm a professional body I guess so and most developing countries use commercial and administration I the certain 30 % of thing here you said between 70 and 90 % on our are not so we're about the same the same level of of coverage but what does it mean most developing countries use conventional
theory on now we have std m and as TDM answered Duration extension implementation something like this of lady and that's the land administration data model by ISO which is a standard that has been developed by a soul more or less so I would say data schema where you can map all this kind of new relationships and other property and place and put it into context and the social but in your domain model takes the standard and extends it because what I was just saying this precision of having a place in living there and having contracts around that is very different in other places and as colonial developing countries that we are on we tried to tell other people what to do so when I walk to another country and tell them all you should split up your land little pieces and give it to everybody but maybe they have different concepts about living in a place maybe they are in a place for some
time and then pass through In our systems in Germany they're very precise but they cannot deal with that they just cannot deal with the the community using some kind of fuzzy area in a fuzzy time amount when there is grass because it has been raining and only every 2nd year come on this is not possible if we Germans for exact this doesn't work so how are you going to take care of this fuzziness and this is what comes in with the social to new domain model and the core values are pro-poor equitable sustainable affordable it should be systematically large-scale scalable and gender-sensitive so we have an issue here we have a code of conduct so that the few women who come to our conference feel like they're welcome around but in other countries it's different nations there's different roles and with different different ideas about a whole gender works and we're trying to take account of this aspect to so why taking into consideration good governance subsidiarity and the continuum of land rights and this continuum of land rights is something from the high precision we have in the so called developed word down to I have no idea that I should own this place if I want to walk through it that's just completely different concept in mind set so on the social turn your domain
model and information tool focuses on 3 things there's a concept model and an information tool I I came in here as the information tool so they told me yeah we have this concept and model you should you supposed to implement the suffer so I open my doctor God map server OpenLayers a little double to get ETL like stuff in stuff out and then starts to set up the thing is that done and has held on all he didn't understand it's a lot more complex because it's fuzzy and your suffers not fuzzy for you suffers exact it doesn't work you have to change that so I had to learn about the model and then to learn about the concert and I'm not done yet but I hope that eventually will understand the whole the whole complexity of this thing but I've learned a lot sold the concept is about so job is to bridge this gap between our having a clear relationship and something not so clear by providing a standard for representing people and relationships independent of the level of formality legality and technical accuracy the differed and get us to something about technical accuracy so in some cases it's it's even better to have that point information with the precision of 20 meters somebody is there instead of having an exact milimeter exact boundary over part and parcel so this isn't there's there's a big a big up there but also legality like you're really old list most slum-dwellers owns the place there is no security but yet there is some kind of security because the municipality doesn't want to evict all of them at the same time because where where those
people go they would go just around the corner and cause trouble at another place so how do you do with those people so legality of the thing is very very ah very difficult to to actually manage and the formalities same thing if there is no form of government that supports something like this then there is no formality there's no process you can goal to a could also office and actually asked to be registered because the office is not there or you only get in there if you have a certain status or a certain connection to somebody else who knows so bridging the gap a complementary approach to
customary and informal tenure the concepts the
model is a specialization of the ISO approved land administration data model and this took place in parallel of the STD and concept and model development so those work together but the energy and what is more the formal things like biosolar and it's clearer nasty game is always evolving and sometimes it even looks different in different places where you implemented the somehow I
didn't have this in the real so this already mentioned suppose rest posters Q gestural the reports and many more that's the basic stuff we used the 1st thing we did was we implemented as a plugin for choosing just because you can just you installed on your machine and runs and runs off line you don't need to be online you can do whatever you want to use feud reports to print paper because you don't want to run with that of 1 of these things and so or in the rain forest or whatever so you put a paper or a plastic or on fabric maps 1 of my favorite max speed is there and what we use is only something that has been graduated so maybe you have been in the country this morning my liking talker was talking about graduated suffered which makes sense because it has all his here so these ones are great they're washable there where you can paint and put to draw something on them for
them in the washing machine and use them again so this kind of stuff also works nicely
so this is a very simple architectures sketch so you have that huge rendering engine you have on that data and imagery data that you can import into in with Mojito GR into the system and then you have printed output there's a map there's a 10 year certificate and there's a report and this 10 year certificate sometimes is the only thing that identifies the person at a place so many people they don't have an identity mentioning this in your in your context so this is the 1st time that they actually have an identity that potential to an authority in the ideal case an NGO doing aid work in in a developing country will use this offered to produce a report together with the
municipality and together they have something that people can sign and cat that get the stamp on so that as they have some kind of tenure security that's the background
future developments everybody said 0 yeah you should do this online which I had sometimes wonder whether really make sense but you're mention that you have a lot of long underwear phones and probably it will make sense more and more as we go along so there will be an online system which is not really a big problem but we have to just data storing data model that security and privacy layers that we didn't have so far because if everything's on that machine that's the security you close it you on that and it's gone it got stolen then it's gone but so on Security and Privacy when you go online is quite a different different topics and also and online components like in the so that adolescents 13 simple and easy to import and export it should be kept aligned with that idea we support OpenStreetMap and Open Data licenses when we want to use Open Data licenses then we have to think about security privacy because exposing the data on the Web requires a highly secure environment transport policy transparent policies and good governance so the security architecture something can be solved technical open governance is something is much more difficult I measure we have this open source system known it's available for download under types people can use it and can say I am a provider of this approach your security how do you know that this guy actually provides new security maybe it's a it's a kind of the criminal mind that wants to get information about people and to find a way to mm it's easier to do land grabbing get get older land so there must be some kind of certification process that those who offered this service have some kind of point where they can be accredited because otherwise you don't know what's going on and
transparent terms of services is also something we're very very short and we want to have in the system that at every point you can say export told staff to whatever data whoever it who's databases so you don't want you try this with Facebook does work in the there was once a part of a group in internal group and they had this export the from Google get everything that is about the person will put it into his if I give it to me and deleted from will the group doesn't exist anymore because it's too complex but something like this should be implemented here so that you can say you can always get all metadata on my private stuff out of the system so the next level of the architecture all looks a little
like this the same thing except that you have a map here with the map service it's secure domain you have a web server delivers this is a browser probably in HTML 5 apples and a query and you have other information so from the desktop from and portal authoritative services OpenStreetMap and all these can now be easily linked into the system and this is a cool thing you can just take them and link them into the system without having to ETL to your local machine so that is a big advantage to going online with the system softened
standards on the system is based on open source suffer components including besides others pose present you just as what we started with and now we have maps are players and Apache and genetics or Apache depending on what you want an open open standards side we have interestingly what you the data format which is what we use of posters impose press but also the ISO lady and data content and all we had watches the W-mass WFS s and du packaged for transport so that you can say I want to get the stuff out of the system goes on to undue package you could just carried away so online
interfaces we use state of the art technology minimize Web traffic support older hardware and any platform is very important we tried you suffer there has been around on the market for atleast 5 years and ideally has Latino requirements on the hardware so we don't take the bleeding edge has stuff whatever great thing we tried to stay low key on mapping components report generation and an anonymous data open data so so we think we believe that some of the data that in a questionnaire in a slump is being evaluated is good to be published as
Open Data but we don't want to have a private catalog of people living there being public so the data model that we developing is being split into private stuff and public service and the public suffers more more generalized and something that you miss municipality can use to calculate how much waste what to remove the the need how much freshwater homage medical services are required in this area and things like that Saul online interfaces use state of the
art technology man is bittersweet right always going online here when and the 5 minutes left I would click here and show you something online let's see whether I can I can finish this there's 5 is there so all the In conclusion source development has proven to be the right choice for STD and standards help to build a sustainable and open system which is easy to use with powerful functionality extendable and customizable into and standardized and transparent and secure so I think I'm not going to show you the online stuff because it's the same
you know you can click in go and see things and it looks nice where some sentence data now there because we're talking to other people here and when the analysis is 1 of the companies here with a microscope and has is grass
engine you click on a button and the just as atmospheric correction and could you could e-mail and then you have the service and I just have 1 button were into the capabilities document and suddenly I have a central data from yesterday on my new mapping area while at school so I could show you this but you know it's just pick stuff but what is interesting is that there is quite a lot of 8 projects and I think this is a
big problem on because they have hard 20 million dollars to spend in 3 years what do they do they're dying 5 thousand licenses a specific suffer then the 3 years project work there and their and their and their then the license runs out what happens the data has gone there's nothing left and this is not just fantasy there's really happens this it happens out there the this suffers being bought or licensed and never used or is being used and like lots of people do lots of great work but after it runs out everything's losses nothing and that's 1 of the main reasons why a habitat has decided to go open source and try to use a sustainable approach and provide a system that people can use themselves now we currently do we have the problem that this technology is way too complicated for many NGO so they don't know how to install this how to maintain it is how to updated or how to teach the local people to actually use it so a combination of providing this as an online services could already does and providing the infrastructure is an open source version is is probably a good valuable way to go for and I think that's enough for me so thank you and there are some questions discussion few questions right highly rounds was the 1st question he and what I have a
question concerning the implementation timing yesterday and all the uh has been around for I think maybe 8 years the least uh I mean I've seen different projects where where this as the section on the agenda to use the the energy MODS CDM for the development and and really seen so far implementation there was also uh that was also an initiative from the FAO to do so which is also an open source toolbox for I don't know if you know about so more yes absolutely uh which had some some pilot implementations in Nepal has gone on this Samoa analyzing so Western which actually is is used to so what was what went wrong and and were locked in and is steady implementation which actually is really adapted by abided by government because I mean who's doing the of blackness in nearly a new set of with NGO and matching is a good thing tells a different matching projects but it has to be adapted by the by the government in the and well that's a question that we're trying to move current you find out so there were several questions 1 of them is doing also oppositional and all the project lead to left so sometimes role but this good suffered as a different the different name that we have it's more aimed for governments this is not aimed for governments this is aimed for N G O's and local little projects so hopefully eventually somebody will be interested in also having this set as the national level but are usually they get caught in up and and in larger organizations so if you say yeah this is open source tool that think it's not really viable so on and we're trying to just get on the ground and get things done there's other implementations not only so others so to more and we're trying to get interactive them but they have all different approaches solve solar is more our Java-based and they try to do everything with their stuff we are more we don't have any software all we have is a lead you just plug that's all all the rest is existing stuff because I don't want to rewrite the MAP engine when there is some change in an OGC standard in 3 years to come let the guys do it at all to do it the years Stefan my or last sort when there is a change you will do it maps are so I don't have to care about this so thing is totally modular and what we care about is the data model and the way that people can actually use it that's the more important aspect not on the other question is like you know we're currently talking to Afghanistan of the MAP agency of the canister and they had this really bad experience 1 of the big sponsors and everything is lost now and they're thinking about not taking the approach to map the whole country 100 per cent which will take I think that calculated that 30 years or something and they say no we don't do this what we do is we go to the area where something is happening so when somebody asked me we send a few people there and do that little area and that's it because we don't have to map the whole country we only have to map those places where there is either a conflict or there is a lot of development and therefore either the tax revenue from the money that comes in from the past or there's too many people and we have trouble to to maintain the people so it's more our project oriented approach but at the same time this Mr. from from Afghanistan he said I don't want another project I don't want another pilot I'm fed up with pilots because they never they never sustainable I want something that can implement now and I know it's going to be there for the next 10 years and this is an option where we can say OK we have to get off the ground and 2 to 3 years we have also educated some of your peoples leaving the university and they will then be able to maintain the thing they will be in your organization you pay them is your people and your system you can start to use it on your own premises does that answer the question there OK and I think a stimulus is actually implements LAT M in this std inversion but it's not been adopted by 1 national companies the cadastre system that's right yes there's time for more questions for the OK welcome then thank you very much OK I can show just this because here online and I have a 3 minutes more so this is the this is the system and I'm going
to have to work with the mouse around the corner so there's going to
be looking very clunky there is the most Jesus to the work of the video gate so this is a different layers of the and this
is an area of photography that they took and provided for this area and when you zoom in you can see some of the yeah the
things that we have already mapped
this is just examples that we did here I flip this up on the 3 years ago it's just for a for a little example but you can also overlay OpenLayers of farming
OpenStreetMap data and then you can see that this area has been mapped already so there's all the little buildings they're not exactly like on the same place but there's a lot of mapping already been going on because this in Haiti thought of balance and we know that something happened there some time ago so there's a lot of OpenStreetMap activity going on there and this makes life easier so people can actually copy their data comes from OpenStreetMap and then add the enumeration reported and from this enumeration report they can produce a certificate so this makes it a lot easier for people from and you also don't have any idea about how this works this juror stuff that just give go with the mouse the and selecting a project here that sector church because it's big enough so it will take it and then you can get it is by you here and say 0 it's not the church or is a church but it's it's the it's the Catholic Church so and then you say updated and this is
so easy that actually anybody can do this so that you can also move base points and you can become more complex so this actually underneath is the same precision that we have in Switzerland or in Germany but we're trying to package it up in a very that people can actually use it and the other thing I wanted to show here and then you for your coffee this will only take this to get way on the
then in the background you see created data that is centered
on the door and I was there when he did it was fantastic
so markers and ask them to do that you shows you what you did there this is the center of data and when you see the origin the raw data
that comes out of the satellite you can't do anything with this and this
is false color information and up here in the port you see something happened in the portrait shows up in red whereas in the RGB you don't see any of that 1 so it's a false color and just don't and several versions and currently talking to them that this is probably not good metadata it should actually describe what's behind their so but this is a a WMS service so this picture here comes from a server in Frankfurt on some of the 1 I was just showing that the church is a server that is in Paris and the other OpenStreetMaps of I don't even know where got the salt and that's that the power of the distributed system you can just included here if 1 of the services doesn't work anymore you just take another 1 and the beta the only data that is really interesting for you is this little little piece here in the middle this
1 here that's the only 1 that you really need and that's 1 if you want to own so this 1 should be on your own premises on your own server maybe even on your own not everything else comes from around the world but this data is your data and you want to have it on your what a bigger bigger about

Abstract The Social Tenure Domain Model (STDM) is a concept, model and information tool to map people-to-land relationships. STDM is developed and maintained by the Global Land Tool Network (GLTN) under the lead of the UN Habitat. The data model was closely aligned with LADM, an ISO standard on Land Management followed by most implementers. When it came to implementing the software tool the GLTN group decided against reinventing the wheel but to check out existing Open Source components (as maintained by the OSGeo Foundation) and Open Standards (as maintained by the OGC). So basically everything from the data model, technology standards and up to all the tools required to do proper Land Administration is already there. But it is too complex for non-technical people to grapple with. Therefore the GLTN group started to implement a software package which shipped with the right data model for the Postgres and PostGIS database, the desktop software QGIS, reporting tools and comprehensive documentation. This presentation will give an overview of the software tool and underlying components to give participants with limited technological background a better understanding of how it works and how they can also profit from the abundance of great Open Source software that is out there.
