but the
but from the here the 1 I'm I'm just a few from and this year is the is that the light buys occasionally I give each presentation so all we had to research on an usually spectra database and we have focused on indoor speech a database of 4 years so today I'm going to have to about the system that we have in the book of implementing the whole ISIS over which is an indoor especially yes over so 1st I review the intro to introduce our project rid of background not talk about the requirement and issues and and then we will look into system design architecture and from with this work so we had participated at R&D project funded by government and from 2007 to 2012 of the title was in endorsed spatial when project the all-word cheap of consisted of 17 from university in a team from new industry had the goal of the project that was developed by the accompanying technologies for indoor beta in this and to test establish a basis for inverse measure theory and data a model also developed system for building and managing and special databases and to develop I occasions systems from the project to be obtained out the status and the special theory as lot of paper and the data model and system such as authoring tools and solver and vision but now the know the data model was the foundation of into which in itself which is 10 . 4 of these applications can channel and our team was in charge of Pisces over so at all since the project to finish it we chapter of implementing some of the altercation on top of the solver and in the meantime I have to maintain this system however and as time goes by really is a function more and more so as you know the the open source project has benefits such as efficient many maintenance or with loading and scalability so to take this kind of advantage we started open-source project the goal of this project is to develop the endorse metadata solver as an open source so this figure shows of north of flow of Oberlander spatial data so construct and manage and use data to in this project we focus on the men in the management of data a weekend intuitively know of our role in this flow so that the system most stored data and to provide that provided data to the data consumers in many different forms so From this other point of view you and I are we specify our requirements and talk about that some features so these are the list of of functional requirements so 1st of the system need to support data and the field index to improve the performance and also the support of some of the support to process a very secure including Street East Bayshore also supported standout former such which ML and parts of city mayor related to our In Norse space not only just normative also the onerous security should be killed I suggest opting for navigation and location of the locations of moving objects are important data so we need to take care of the tracking moving objects in indoor space also alter it is exists and non-functional requirements and it it as it and told you about previous in previous projects probably we didn't use any open source that so that in this project we like to maximize utilization of open source project really related to our project also we need to set up unbearable for project management using up people working so from that this requirement we surveyed and found some related the open source project so they are due tools and use over the Gulf as as if she go and jealousy pp I'm going to about this item of briefly and some teachers so as you know utilities that is open source Java library which provides standard-compliant method for the manipulation and use spatial data and the data structure of these of the chill tools are based on what is she aspects such as a general filters however are few tools has limitations for implementing our system the 1st i Stewart tools our support to read only cover feature in asking a module so compared to using the picture of accomplish the public feature is a feature that has no associations and attributes read a multiplicity because the applications schema as in Boston or institutional may contain complex feature so we do so what we'll expanded so that we can this for complex feature and 2nd the 2nd is the that the joke tools does not support through the operation at the moment they have due idea so tumor it's a 3 data model but implementation of a bias sentiment Teresa on so or to the module and this read operations and not get out I'm not implemented yet yeah so we could developed the special operations from scratch but we don't need to because seagull you can so of provide a basis for implementing really special operations on the signal is a library of was library that's our support competition geometry of reason and written written in C + + and the strength of the signal is the role means so we can solve of the prison problems that we encountered during the implemented system so all fill the gap of between as well and the just tools of theory is is is the mountain of our library simple Patricia got it's a open source library based on pseudo written into the the plus and also the support I Szityu you matri including 3 operation so we have included the of sorry I think we are evil until the talk about the and later so mean the obvious what the issue is how to combine this year as if she called me that you'll tools and in other words the how the book the was called from Java it is very common problem and a lot of solution so we selected to candidate of bridge between Java and C + + was us 3 and was CPB so we attempt to use at each of each module and we'll determine the user jealousy pp because it was easy to implement the as soon as the jewel tools is just library so we need the of functional units over so Due to a forward and solution was useful results a server based on dual tools for sharing geospatial data and a it's a limitation of a lot of . what is standards such as the web feature service and then the service and the so we have designed and our system to make them these requirements and I'm going from now on I'm going to talk about our new so the this
figure shows the whole overall architectural vices solver so biases over consist of dual solver and you'll tools libraries due to expansion and you just plug ins so and is for indentation we're going to focus on the model that we that we're involving extensions and plug in I in our import pass through the geometry and complex features like session model that these 2 more you can I can stand alone as a just so judges what extensions so make them explain each each item on in its traditional that tree extension of i isochore military is the implementation of Clinger as interface and as I mentioned before the Ford implementing the geometry operation so we are deploying an exceptional and we made some In the wrapper classes in Java so we use that of jealousy pp as a breach and when the 3 operations are for In both are there the the tumor tree as a parameter of the of the converted into that but you got refer to other classes so we having implemented of most
of our operations such as well the 4th category more something but we are struggling implementing a special relations on so here we have we implemented of relation space and a special relation between us all to solely only valid problem that between also lead and holding on more slowly than my strangers problem and some cases so when I found the the single data part converted into the dual tools no holding all 3 are are split into several pieces so we're going to do we're going to also find solutions the same and
it's a complicated extension model that I true yeah but stated in our design phase so on it is planned they're going to have to be composed of complex feature into superfeatures the In accordance with the the the the number all of the number of attributes attributes reader were duplicity so do we need to manage of the map mapping between a complex feature and super I think it will be very useful to know any kind the application schema and this is our
eyes and extensions so it's important to come the feature has richer Macherey and on here to shining the schema it includes contains a moving object in space such as room and the topology of the network and the structure like the law of flat and that we will always point to its laments that some of closing so that the IC and can import and export city general and Andalusian so it is the state of the real dissenting views support analysis curious suggests rocking warm imaging and so on so summary I solvers open-source library in the the solver based on dual tools and use over so and it can store and managing larger spatial data and his support secure very cure including spatio operation and analysis periods in and or space also supports data formats such as in the channel and part of the so we will expect that the IOC's solver will be a common and it's over for indoor geospatial data and widely used and on various of the altercation like and many monitoring what's service more Y so this'll information so that's it thank you for your attention
any questions be it the I and it and right back I see you have done all this that about and what are you using this even for the you have so use case that we are using it the actual know no not so that as I told you so we had some publications in previous projects that may be that it's a mean that application that depends on our previous over so I think a we need that make maybe implement another no publication for to change the interface right so yeah can become whether any type of occasions so like and so 1 example was a finding of most time and memory yeah yes no using some tech ovary K or context so so the that means that when the child is lost the sense data location data to friends so the parents will find the time like that so any travel occasion I think I can the thank you the other questions the when it comes to 0 you have a complex features so as to which level of detail depends to impede the things FIL retained a path through the parse in the the mapping the played the display it so you have I P about that had the head in indoor environmental so can you met predate feature can map this treaty feature yeah into node you mean that Is that what about the years yet so they know what he was about to detect then I mean delays at the tide of war sort of thing that quite quite again intersection sort of thing in the the find yeah read them in yeah yeah during and have try to you know all of this the 1 that that the kind of cure is at most a run at endocytic negative so we just of support to basic URI and then maybe we can be extended to know I find that moment the war in in this additional high at the moment she means uh just when you have a location just method of search in room so in other related to come in here discussed yet and

Abstract In order to implement indoor spatial information services, we need an indoor spatial data server. However due to the differences of indoor space from outdoor, most conventional geospatial data servers are not adequate for indoor spatial data. First the position in indoor space can be specified by the identifier of cell containing the position rather than (x,y,z) coordinates. Second, indoor space is considered as a set of non-overlapping indoor cells unlike outdoor space. Third, the indoor distance metrics must be differently defined from Euclidian space considering obstacles such as walls, doors, and stairs. We developed a spatial data server called ISA (Indoor Spatial Awareness) server to meet the requirements of indoor spatial data and have been working for converting it to an open source using GeoTools. With the ISA server, we can store and manage indoor spatial objects, whether stationary or mobiles, and retrieve objects with indoor spatial predicates. We expect that this server will be used as a common data server for indoor spatial information applications.
