and we're going to start with this and said we're going to talk about the use of open web standards in its review their decision of archaeological date. i'm all over when my name is a usable dollar. we'll be talking about the use of in which standards in three visualisation of archaeological data. the talk is going to be about the weather occasion that we have a. it's like ok. the talk is going to be about a with applications that we have made to visualize an archaeological site at the beginning of going to be introduced the archaeological site a little bit about its geography and stuff and i'm going to talk about the progress off the set off to the the new project regarding this archaeological sites and when. for the publication comes the. in the game and then i'm going to talk about the challenges that we faced the. developing the application soul the site is located in the altai the mountain.
the it is located in the southern part of the russian federation just between mongolia china and pakistan. and in the mountain rate it's located in the north in western the part of the mountain range and central asia.
this is the conservation park that was represented in the application it's surrounded by the but borders and the yellow spots represents the areas with archaeological the significance.
i'm the same time montand the region is a region that is populated mainly by continuance of the indigenous the and habits and and the russians and kazakh people. it was populated by intimate to the tribes for most of its history. some and is known as the safety and heartland and the safety in people or a nomadic culture that flourished the two thousand five hundred years ago they didn't left behind any settlements or written documents and basically they have a uterus to read that they occupied and they have a strong interaction with other cultures. there's a lot of friends thing for them and the greek the literature the most evidence of their existence it's the their rituals in burying their debt the they have a an interesting and bopping and mummification and they have a really interesting burial mound and a famous by with putting treasures in there. grace.
this is a picture of one of the burial mound it's the circle with the stones on top of it. and they also have a standing stones and these are the most famous features of their heritage.
and the push to make its nature park was created to for the purpose of the kinds of asian of the archaeological sites that to consist of ten thousand square kilometers he was established for the purpose of the protection of the archaeological sites to create public awareness indication. in and to support to resume off the region there is a set of international activities between get university and the department of cartography that into the institute of cartography and technical university of justin. i'm one of the targets of this the corporation is to create a virtual conservation site and three d. for bush in the uk and the motivation for this is to support the conservation and to create a web based information awareness and also to simulate to resume. a little bit of the history of the to the three d. model or the data that the publication used. there was a sip of research and and projects first there was a creation of the topography model using the maps and you database and then using this satellite imagery a semantic clean hands j a small was created also a d.a.'s model with three d. consistency using the elevation data from. the satellite imagery was created then a set of of projects in the three the modeling was conducted and basically they ended up with creating prototypes for the fingerprints of the buildings and summary creation offers specific optics in three d. like the burial mound and the addition. and the. at the last there was a refined three d. model. and application comes in the presentation from are you there should be and this model needed to be accessible for the public. i'm so the design consideration for this were publication that will visualize the three d. model the is to create a do model as a door for internal and external information also the idea was to provide a multi scale visualisation because when it comes to archaeology the user might be. said in a small artefact or a big village so we need to provide a visualization the four balls scales. also the openness for other information types to integration of different archaeological data was ideas that to be considered. so the start about the application so we started by using different victor layers represents a man may teachers natural features and and what's not also we had a digital innovation model and a satellite imagery.
to the two different the three d. model for villages was created the was rendered in cinema for the was created this is a vicious not show from the video rendering of the sea. the idea of the the application is very simple the user will be interact and the client side with the application cesium is the core technology for this application the data sets in the service side and survey of different applications the days of a no.
express and the a goal server serve the terrain and the apaches the serves the rest of the study finds season also provide the ability to do to request what map services and the user will be interact with the three d. model and the decline. a little bit of introduction about season for people who didn't hear about it it's a it's an open source just ripped library for world class three the globe some apps it's built on a channel five to technology namely what geo and has a. in that resembles the game indians and this is why it actually works very good when it comes to visualizing dynamic data. this is a little bit of this is a graph to explain the graphic stuff of caesium luckily we only had to use the top player so we can all of our data can be represented as primitive we have the globe and the glow can represent the to rain and image are layers they have to be provided in. quite tree format three d. models are represented in a format called g l t f and the primitive is actually the way that's easy and for all shapes and the victim data can be drawn using as normal primitive.
there were three main challenges to the developing the application the first was about the three d. model so the three d. model him it was initially designed and built to be rendered in the cinema for the framework which means that it was not spatially referenced it also is not linked to any. and of additional information so you have blank the cube's that's basically that the three d. models that we have the other issue is about the terrain data cesium does not allow you to the winter your own to ring data out of the box seat and the model was built on top of the data that has a different source than the one that used by default by see him. so we have to use our own to rain data. am the other challenging part was the underground chamber is which is the more significant the archaeological features the problem is that they are underground so the cameras somehow need to penetrate the terrain the other issue is that they are in door so that the navigation events in cesium more for looking from top not. the within that did not convenient was indoor navigation. so regarding the three d. model as i said the deal to be a model which is a day some based spec its kind of a decent collider little you can say it also allows the note herrity so every feature can be defined the the divided into child nodes. and the shade isn't the textures can be injected with in this child note. in cesium there is a m. i thought called seen think so when the user click on the g.o.p. on a g.o.p. if model can gives back the idea of the click no sophie have a model that is segmented to note we can retrieve the idea of each know that selected and the idea is that we will use this id to fetch the. the data from the days and then render the in the winter it in a statement. the model was this is a picture with the model was only in one note so we had to select all the connected matches and segment them and independent node and we had to use to do this manually for join and then we gave them an id that matches the idea that will be.
in the database.
for the days we just feel of a prototype the prototypical days with no scheme and north and station or any of this stuff. because we just wanted to test this linkage approach we also added to put request so that be allowed crowd sourcing and test v.d.i. approach in this project. regarding the the to rain data handling cesium use is this what we approach to visualize the to rein in this like the imagery thing when you zoom to be based on those whom the value you re to receive a certain. and tiles there are two different two types of data that our native leap are supported by cesium one is called the hijab in the one called the quantities mission i don't have the time or the enough information to explain them in the. but we have three options to to use our own customized to read it first one is that is to catering it's a commercial to the created by a.g.i. the company that develops use him itself and it provides a quiet ties and comfort our data into quantities much data. someone is season to rain builder and it provides hype and there is a plug in called you sir are the to rain provider and at the time of the working in this project the slogan was not maintained so it didn't work with the version that we were using i think they have dated recently. so we had to settle with the season to rebuild the season to remember there is a c. plus plus a library that is associated with a combined lentils it's developed by the due date institute through the university of southampton. creates a tie set that sits behind any to rain server that serves this child said and it accepts all the details supported the format for innovation data.
the last time and who was the burial jumpers and as i said it's underground so the camera nice to find a way to get in underground or under the surface and also its indoor and when it comes a virtual globe so the camera position and orientation and movement. is it is designed for the view from the top.
i'm one of the poll solution was to use this plane called from push and the thing is also it's not maintain and it acts a little bit funny around the edges so even if we used it it's not going to perform perfectly but if you have a data that is below the sea surface i think that's the only choice. you have to to use.
so the work around that he used was. to first to disable the terrain and to move the camera inside the rooms. and other thing that needed is that we also disabled the default navigation events and then we have identified our own navigation events all of this happened using the a.p.i. we didn't play or manipulate the core sort of the source code. so when you have an event like the most move the end and when you look at the globe most move actually and the the the the ground but when when you're indoor most move actually make the camera looks around. a little bit demonstration to see how. the occasion.
so you have the site over here and it actually consists of two main sites one is got a call and the other is the twitter.
the cesium by default provide as they said their different what map services that can be viewed you can also view your own customized.
imagery.
and as for the victor layers. you can you switch on and off you can see the victor layers and also it's supported by default in cesium when you click on any featured the attribute table.
can be viewed.
the when you switch the three d. depiction the to ring data is rendered and also the three d. model is rendered.
and as you can see its it's nice on top of the to rent it out because this is a van that was developed and when you click on a building these are the data that are retrieved and rendered the city from the days and rendered you can also call it the description.
and add any. type of data that you can use so this source the the crowd can actually help the provide data for the for the model.
the last feature and the application is the the real mound when you click at the camera actually means.
the site. the room and when you click the camera looks around and you move backwards and forwards when you click on the artefacts you get to.
freedom from nation about them.
this feature was developed in the last week so that's why it does not perform perfectly so. if we had enough time we could have done a better job but it works. that and thank you.
you mentioned soft to reason and i was just wondering my own curiosity what the soft to reason it actually means that visiting the place without visiting the facebook and get a sense they're not going there and virtually visiting it's pretty far as well you know yet. ok you can see your dander for the kind of your experience swiss gold medals yeah i mean it's a little bit experimental even sees itself but they are having some work to become a customized this is a v r r k r b a. yes it's is your because you don't have to to the actual number is the decision making and i guess those villages have evolved over time i come back again i guess those villages they have evolved developed over time as region so you may be missed a good. the possibility of seeing that evolve on the go. no but yeah i mean. and it is one of the proposals to to test the the time element and the to find a way to adapt to changes that happens to the region. the focus actually it comes to food to the images because a the idea is to try to remember images and different seasons with the snow we ground and the experience to draw some party goes on resent this known and stuff like that and in season i think it's it's a little more us. dirac theoretically. ok anything from from the audience. you were pointing. then think you said. welcome to find now. you all for jal is your knowledge of mine was the g i use sector demons. and. it's just. and.
