and the around my presentations about
than a point source so it just enough room for it is the same vector system so some
that some rather than a natural disaster is they're increasing a lot impact its influence on a lot in doing their room remember that and then there has mimic such as flood the landslide this great and the other is they're producing gaze so many losses this clusters can be calculated by the damage extends from the houses infrastructure fatalities and injuries and then we can compare that led to the financial losses in the beginning of the and it is so difficult because we don't have so many formation so initially the initial assessment can be done but they're later when we have more information than we can do the post-disaster centered about the initial assessment the beginning of the yes and in so the posteriors is like our own modem until the air squared that learning in half a million fatalities all happened and the usually the dimension of the from the damage that patterns really difficult to produce and has that map is usually taking time it lets up before so to have the hazard maps is so expensive that it landed on us so that they're building and then another 2 that that they need a huge amount of data is so we can use the opened as source-filter and also we can use them book their expert knowledge and then an inability to our application and use it for the initial assessment the case that knowledge you provide for us is providing a wider range of solution to map the standards and also to have a better therefore the easy and this their budgets especially when it's open source so you see here and an is a because I'm focusing their Nicholas would be something happened in April 25 it was sitting on a on meager step and the aftershock was treat anything effort that they're going with the number of the network and so this was the largest during the fee for the past few years the square the kid like around 8 thousand 700 people intermediate hasn't people injured and more than 500 houses the police were doing this 1st great and aftershock yeah so both you
to that for the 1st this we might be aftershock we just forces the forces more than 2 million houses were damaged and then 160 thousand more than 160 thousand houses totally destroyed in this so that
means we use some form of to get a little bit last and use their expert knowledge for the probability of the intensity for the area after this and when we add to act application and we can the last using the funds financial uh the 1st so the object of is knowledge the same with my colleagues we are using the OpenGeo in their clients and it's always going to open land jokes there and then use a server and the server fan aperture Tomcat From here for the use and management I'm using their uh an open source graph the you voted and is using this QL because I made separately the use and management with the pause gruesome posters the special on so this
is the main view of mine the application that is not so much the the main panels looks like the jokes are so you have the Mac you had the latter when you have the data and in the top panels for their use and management so that any can the determination of the the different you just use that to use the application for the permission and they're advantageous the person 1st
their news that we upload the data into the application that in shipment and it's easy to find you can find it easily from the US data directly after the 1st link and then uploaded well you can also add square information to the maps mostly at they expect to have they have to do that and then after that you need the building they come so as I said the balloon that was not easy to handle but we use the open a stick they and the and the nodes associated with the internet overlap 5 administrative unit so it's really that I was mostly in their central part so I think that the central part of the from the openness to data and you can have the of from after that we need that will and things so we need to see there intensity from their shaking the air mapped to there are blooming area and we will do some analysis in the pursuit and uh and then after that we need to get little bit all members of the house is that affected in that area the then you can select the level of there's that that you already uploaded and then did the ruling data that you already uploaded to the system and then another look at the probability as of that means in that area that was his can be extended in purple by the expert in our system and incalculable losses
the so the so I want to add this to the use this as a rapid growth and this the shape mapping principle is from most of the damage and elsewhere happen here and the is the area of the damage and the blue they're on to you and 100 thousand links that improve the to the poster 1st and then we take a look at past sample and then uh between the different intensity of their as squared so 120 thousand the Bellman registered India in that uh as quick and the industry level of global like not to talk to about half the image or maybe this image so there were a total building expose in that area with 2 on and the vessel is there new for the value of the building we use the uh the prosperous square meters so we have the balloon from open students that need to be in their stories of the blue and then we calculate the price for each program so that the terrorist is an odd because the process is the ranging from 250 about to 615 so there is less than it will be between 27 women that you have to flip it will you and and if you remember I mentioned a new 1 group that allows the the destroyer but at a disturbance but 160 thousand and liberty and you know through the houses were also expose and undamaging that in that area so we are kind of close to but the report that later that do this as fast and you can't just make up the data for the
conclusion it was the yeah this so these systems for higher for the stability and usability is fast minimalist digit middle it's all open source data and some software and application we can do in and of they got you can go to the Union buildings and the loss of new moving band that using them open data like you use all of OpenStreetMap you estate up number for the price of the house and then uh to get the the administrative unit from down database but as I mentioned this is the initial assessment so it's not at a group for the last calculations of this system is still under their development so I'm trying to improve their their user management things and scheme for their expert knowledge and how we can improve their In our open-source data to use really for the most accurate lattice image thank you for be used shot part of the state of the theory of you always stress that I had the bird their in yeah yeah yeah Our in the OK with the visual the use of

Abstract Natural disaster impacts have increased worldwide in the last decades. Earthquakes are one of the disasters that have been studied for real-time analysis and crisis management. Disaster- related losses have been examined by damage extent of the houses, infrastructures, fatalities and injuries converted to financial losses. WebGIS technologies provide a wide range of solutions to map those damages, analyse data and publish the results. Open-Source tools and data have been widely used today because they stay free and facilitate access to data especially significant in developing countries. This research presents a WebGIS prototype using Open-Source Geo-Spatial technologies such as PostGIS, Geoserver, Geoexplorer and OpenStreetMap (OSM) to evaluate the rapid impact of naturally produced disasters for total damages. For this purpose, expert knowledge such as earthquake intensities and vulnerability inputs are imported into the system and the loss of the damage is rapidly estimated. This work is part of a project for catastrophe modeling based on Open-Source data and software. We hope that involving Open-Source knowledge into our application will decrease the time and efforts needed for rapid disaster and catastrophe management.
