4 months and then I'm going to talk to you about open source to and fro surveying applications especially in the field of what the management so and yes the
you don't know Sunday we're chairs company open-source GS company you can go on a website a number more that's not subjective today
and today I got at you about so 1st the context of the project we will that we realized but then the exact needs to send or about GA has brought to have developed for this project and I talk about data as well and san that most specifically about serving and so that's the heart belts and send the software belts for serving application we developed and I have a world about festooning to and not extends to assimilation and the future of support so but the main but would be a lot of rain had lots of so the context of this
project is of placing will menial which is good divide yet couldn't T and that's about 3 100 thousand people and so actually it's way known because it's so it's called the capital from the hikers uh it's a place where all the people are trying to do fishing to your e-mail icon the itself and that the D interview corrosive and hence sunglasses in noise but do it but that doesn't do some like no more stuff and so uh there is a European project for the what's that what development in this country and so and so they got money to improve alter the water distribution and wastewater as so that some more or less 29 pumping station and 19 with with the station I 1000 committals of a distribution pipes and 250 committals of waste water around so there was there was a strong need for a GA set up that quite nosing to organize this project the project is very go 1 it goes from the planning to uh I t to buying the land and to bang pipes and actually beading so what network distribution of torque every talking about GIS on these or what we see up of the company which is the company in charge of what a distribution so that it was uh a
desktop jails 1st in it it's employer you to be able to do DIS on the classic desktop machine as needed of the data model as well so for what the distributions we you wanted to beads and molding of for that as and it is a centralized data repository as well uh surveying tools which is the main focus here and answers that some very specific needs a given the constraint of the countries had to do offline uh because there is no Internet everywhere so as that to be able to do so varying with offline management and so wanted to do so to uh to have version management of a Data also wanted to be able to do scenarios as summaries and so on and to say OK if we develop this but what's going up and so from 1 version of the data and being able to have different branches and it took a bullet as simulation coping was in Puntland as well so being about to run a simulation for what the distribution and then on the present needs it was map and Web rendering so we provided them with his expertise uh we had to use jet to buy hardware and as for the Jays disturbed and for the serving to use and of course that defines himself to and they were very keen to a pencil so they wanted to software for all of the application and beat so disturbed years serving for us 0 my god and when rendering as well so that reason that's a
bit further on us for the best of GA as with the choice was quite a don't know now you want OQG use so that's the reporter could chose to deploy for desktop application and and so we did a lot of project development aiming to just project development and lower project so as to to mining what object where we were gonna use was a symbol that you would be from uh the different objects uh defining composer to be able to print maps and to edit some specific forms as well as for the user for the best objectives user to be able to enter the data and was good economics I we provide some pride training have you probably know that duties use is very uh extensible as so there was a lot of plug-in development to adapt to the interface to the specific needs so we provided training as well so that they would be able to develop their own protein and for the very specific needs slots for the best
objective as so that the data repository where years was a good choice as well how probably the best 1 the we used version 9 . we and we have a data model designed to do so I talk about that just after every provided training as well and pushchairs lots of was everything new for them and we so used as a special lights for on Beatty data so for us an embedded database and especially for offline management laughter is a GA
as such that you we're we're using so Q juice as a client desktop clients the for our data management said database management so uh uh we pigeon were a bit for us so that the race that those of the central data repository on the server was a suspicion that the basal pose with sequence on and yes and some additional Pfizer's where for west operated thoughts runs on a PC at once on the server and the server here is of the 1 we and paid attention to for this project because of specific and constraint that's offline walls for example so we had a tablets talk about lots of us a lot of mobile clients sets of PC tablets and the data had to be embedded as well inside to the supreme pure material and software so we use specialized and was the lie to data uh onto hardware and between the center repository and besides so embedded database we develop a specific synchronization tour of of foreign of line management and destiny the that's a global pigeons article this and his birth more specifically 1st
or as a data model so we needed to distribution what the distribution data models as well as a waste what a data model as there is no stalled on the Globus on all 4 of our dis water distribution of models so so we talked with uh with Caesar of Swiss and a public of ganization into other for what the distribution and sale of like uh a project which is named Q what's which concentrates on a focus on what as well so we tried to lies efforts to get the same data models lots of our development we could make on our own uh could also be interesting for the same and opposite what they were developing could be used and all of that data so the mother's pretty complex because you get nodes sperm survives leaks by station presses on acceptor tyrosyl lots of different objects and relations but it's a pity may choose a data model for what of distribution and so we're glad to be able to use it and and discuss with them on some modifications we had to make as for wastewater that still walking progress as there is a assistant others words so maybe you can use that but not for sure yet but the
model still serving specifically so 1st thought was getting good a hardware for surveying so
uh we needed the GPS antenna we use the and leak as in those Gigi's usury and the and how will express a lot of me then who chose that but the approaches is that the top of the top antenna GPS dinner pretty expenses and so has as it did want to
use the um is embedded device which was developed with the antenna so choose to buy some of PC tablets of pursuing to tablets so that a rough tablets and the you can use it under any condition that the Panasonic G a but G 1 edited you want it as a very good hardware and there you can see have been to
use it and some thoughts that's a hardware set up so by this indicates a G 1 and it's gets Windows 8 uh and so we need to stay with Windows because drivers for Internet on the available for Windows so we can switch to my next but so I have b we could use Windows 7 which was much better on the tablet so it's high in tablet so it's uh 64 due to rights of 64 bytes architecture for Jacobus from a 100 to tend ice as as the disk and it's got wife good brood do so it's got so for connection attendance at age is creating has good that's status on the slide and it goes quite a lot so as to John of that has 2005 on what the words which is integral sign on 3 to resource and also something the the so hi and of most important part is that it's it's a PC Ataturk so it's not underrated it's not the it's not IOS bits of a Windows tablets with what exactly like a PC so software we could have used q is
just like just like is just are all out of on the understand that because this is a Windows 1 but since it's oriented to so that and and using the stylus like Judas's really not adapted to the ordinal if you tried duties and attaching to just menus who's of fingers it doesn't walk so we have to find something gets which world uh would be more adapted to surveying and uh more that 2 oral specific constraint on all specific field which is what the management thoughts that someone working in the
direct that's a constraint we had 4 of
the Code of tablets of tree so we wanted to see an immediate GPS support which is the internet we have we wanted domain-specific object as well so not like a generate GAS but very specific objects that bites in and and vise and all that wanted to be able to digitize directly in the time that we want to be able to take notes to use a camera to take pictures uh we wanted a good guy and good economy especially for touch and stylus and so we wanted that to be open source configurable translatable into Romanian and we wanted like a q jeez compatibility what does it mean that mean you wanted was what Donaldson of onto best up to be also use borrow onto a serving hard and soft so now let's present you wrong so overwhelming the 2 were made by another on would war walks for DMS in Australia and that's an open source a petition that the specific application but it's approach so it's based on q gist libraries and so uh but it's it's a very different applications completely separate project but you can use the same wondering and you can use the same project so every project you do in q j so you can use it was what the that's that was a very good point in term of and the tradition of if at you don't have to read was what you did on a desktop play can directly use of what you did in a desktop on uh URIs having his of it's got a roster uh vectorized also same project and send wondering is 1 means of mobs are exactly 6 value of vector roster and you can do online or offline data management so that's a pretty good project is that data in special lights or you can use whatever they tell you want and so a very important point and got a project management guys so I show you some squinted just after as so that's developing a new project for a mobile application is really easy the talk I that's uh as you can
see it's a very simple interface at very oriented towards the surveying because you don't have any menu you don't even need a smaller amounts that such big buttons of very simple features but the important features so and that's exactly as the rendering like we could see as it encourages so what would you do if you just project and then used it was wrong and you can see the main features which are a class Cj as features and you have cover users well capture for her digitizing was a GPS get point for example and you have access to
attributes as well so you can select any elements and access to this information which are a specific used to the pipes a sudden in get any of you read when no I can't be but that's a pipe and
so you can and new data you have specific forms of flows data you want to enter in so it's very clear it's very big you don't have any uh programmed to enter your data that
you can going pretty configures the forms so so that you can have some predefined data as that you know exactly what you typing so we have the church about for a
2 and 4 of for typing node at 4 are uh no other whatever but I
considered the object's URI with created a
new object you can have some different rustily years as background and so you can
get data so you can uh we got the GPS unscented with a new elements as soon as you move or you can't get chosen point to so let's zip
petition final petition so you can see it's very
simple but it's very efficient in terms of ring to what is good was
wrong is is that it's not only an application it's a permit application you can be application with it and you get a project-management guy wasn't uh so
that you can define all your pretty cation inside a guys so I would say I got a new project for example a tree inspection projects that December project from all and again uh you can select a few different configuration option for example title description you can select so you you they could q just project and then you can select the videos you want to display it in this very low or
or kind of them of configuration and then you can see the map as a as a final application we run the risk you
can as well completely configures the forms you're gonna have available for you use them so you can say I want a field which is of type list for example I want of specific values for this is that it's at a writer to us so every kind of from user configurable on you have bridge you and you generates
uh actually is a project which I show you uh earlier so it's very easy we actually set up the 1st project for the clients are showing in all you do that and then we said OK you better project management tool and it beats on projects on application within in a few weeks without problems was like so 1 point uh was versioning as well so we had strong
project requirements we want to date Street wanted offline walking and he wanted to know you management so that's uh altogether makes my dad data-management they'd of asinine needs and so we actually be 2 new projects or God Gertruda's pressing a which is data based on posterior some special lights uh and which is kind of subversion for all of it for the database so was a concept of commits branches and with a conflict management
so principle is you get a working copy and you get an offline copy of the data you get it on a table its director other and you can walk on its and then get it back to the central the base and you can as well as I do walking copy inside the database wasn't result owing to put it on a tablet so you can work directly in everything inside of that at the walk so had
to uh a data data on so units of reference repository which is the main which is a tree from data 1st order Q who creates a working copy for you user here so you get a local that the base than you do modification offline and so of step is to do the walking computer dates uh whenever there is conflict you have to do with conflict and managed uh your modifications with some modifications which have been done I mean why advisor user B and then once everything is alright you can come at a modification to the reference repository and the user B can do exactly the same as in between so we get the versioning and we get off line and we got uh some conflict management or so
every time you come it'll data are you gonna say how come it misstates and it's a uh OK it's you successfully committed to but you you modification to that of a so it's a so you of some of these to the reform
we get conflict management so typically we got here a data which has been modified on both sides so the inside Q. juice you have an interface as it was can choose which they tell you want to keep or you can do modification of it of last point was about
simulation that's not exactly aims at an extension of uh what the project nobody I we integrated at at Bennett which is uh I don't exist simulation where you can't have assignments in and you can destination on so what networks uh into the to know what pressure will be up on what pipes and Exeter truck and we integrated that into the geoprocessing here um the interface that can start so it's a pretty you
candidate templates for example of the what leader of thank you get map of results we is a specific pressure points was we said uh indication on pressure level for different by personal so we're gonna do the same way so as to be you mn which is called post-edition fall with what so for the future
of the project so that was what was developed as if you chose a project is said to have better domain specific object so as a result of hugest sky may need to to do and to better integrate some water management tourists uh we want to improve the serving software as well so this tracking has been done captured data on them and can thus has been done on already as well but the wrong a petition can be no extended with pregnant so that you can add some new features to the serving application and sensory some of our model 1 improvement for us get a connection for example to controlled uh survives and remote I do web services and uh sense-oriented services and nobody to have an integrated as software stacks for what a management with the distribution and try to be the community as well so every people are interested in what the distributions of open source basin cuties budgets the invited to contribute to use it and then to find it difficult the so
that was the policy of presentation if any any question do not it it's inquiry sometimes for questions thank questions the
question what's the idea the the thank do you know if there some application for a talking green spaces management heat and POX in-degrees based management In the same way the and so I don't know if there is any actually alive of his not directly there probably there are some people who developed on petitions of 4 parts management and duties the other 2 D and 3 should so I didn't try to get closer to use it and lets you should already got skewed juice and so you just project on or if you want to do some serving as its want to his for easy it's easy to set I mean within a few days you can have your of your application running and so if you don't need a new real complicated synchronization eyes but is it a set of so yes in the I was wondering if they the suffer for doing this synchronization between q just in uh in sequel light is available yeah it's available at some detail below a good to us on this that is to the for so I say it quotes in this case uh we haven't deployed it's all project on this 1 but you can Donnelly use its and so it's of I have another question you about our composers in cages seems like when I have used them than produces very large media files uh the problem where it gets out of so you have 2 modes for expressing their composers laughter of a vector load all you of a roster mode so you have to check that your modes for exporting and sometimes as somebody else cannot be exported as a vector of so the war composer exports is converted to roster slot may be the case and so we are actually walking as well on improving the years reduced so let's say we cannot some of like really good SCG export from dude users who want to go to its literal something else and to have better idea eating for vector or the victim of you the the for 1 operation that motion preference singular if the

Abstract It became possible lately to deploy a full OpenSource application stack for field surveying. This presentation describes a water distribution and waste-water management project from a technical point of view, with a strong integration of mobile tools within an industrialized GIS.This projects features a GIS part, with a centralized reference data storage leveraging PostgreSQL/PostGIS, and uses QGIS as a user interface. This combination allows to manage custom data with high volumes efficiently. The project also includes an important mobile side. Implemented on a rugged tablet, a custom tool has been setup to capture and enrich field data. The software is based on ROAM, a new OpenSource software designed for field survey. The tablet is connected on a 3G/4G network and takes advantage of a GNSS antenna to increase GPS precision. It also features an autonomous offline data management module, so as to be able to work in bad network access conditions. The tablet also embeds all required data for greater efficiency. One specificity of this project is the implementation of a synchronization tool between the data used in mobile situation and the reference data, in a multi-user environment.This synchronization tool, developed with PostGIS and SpatiaLite, let users manage data history, data modifications, data merges, offline mode, as well as branches, for parallel versions of the same data. The latter enables the design of evolution scenarios of the network. A classic issue of the surveying work in mobile situation is therefore solved, being able to work in a disconnected mode with multiple land surveying teams smoothly, while keeping data traceability.The project currently evolves towards water simulation integration, interconnection with SCADA industrial systems, and sensor data automated integration (through webservices).All These components therefore constitute a full software package, fully opensource. The various components can be used for other applications than water management. The new features developed thanks to this project can solve mobile GIS issues, and optimize the TCO of GIS solutions for industrial projects, for real-world critical applications.
