and the
that the lieutenant for some anaphors let me introduce myself a it's in this sled and remand hydrogen your that you can call me I up I'm from the Philippines and as fair said the yacht colleagues we work of the the the project funded by the Department of Science and Technology project no 1 and I'm going to talk about that a little bit but actually there will be another session about project no later in the next session and so I have some interesting things for you this afternoon we the really proud of we got at Web safe and it's uh and we like to think of it as and online exposure and risk assessment tool I'm not but before we go into the details of that and like to give you a picture of what it's like in the Philippines when it comes to disaster management and mitigation so here is an animation the idea of
all the tracks of typhoons from the fifties up to the nineties so if any weight allele bad we will see that most father of the country discovered made they fruits and actually we have around 20 to 25 on the average day forms for year so disaster management is a big thing I mean it's a necessity in our country so disaster what is this as
the hand so we the question is so that's having diphones uh automatically translate to having disaster where are studies show that know and you also they phones are just natural hazards I'm having this hazards does not mean there's going to be a disaster we also need all the things that our going to be affected by the hazards with all this exposure the exposure could be as humans are the buildings infrastructure the also another thing that determines the disaster would be with their ability so hot how will you know about these things do that natural hazards so this thing's all contribute to having a disaster and so that's why uh a so here's
a quote from the world risk index apart from from 2013 a hunt this risk of becoming a victim of a disaster is not determined solely by its exposure to natural hazards but so crucial extend also by the way that societies state of development so how ready are you when the has gone pain so has a picture where we can see and so this explains what I've been talking about and there's a natural hazards fear to a disaster and then there's that society those fear so when it comes to natural hazard we can't really do anything do much about it we can't say that their food and the let so you can say it should postpone its arrival this because we're not ready but we can do something about the societal there we can provide tools we can educate the people and and make them more ready for has a so by decreasing the vulnerability we also decrease the possibility of having a disaster this like uh project no 1
was born but acknowledged or nationwide abrasion and assessment of hazards is a nationwide disaster management program which aims to improve the government and Filipino people's capacity to respond against impact and effect of extreme weather conditions so what we do at project all is it actually gather all information all data that we think will help when it comes to this aster a management and mitigation also empower stakeholders re re educate them we provide tools for them that they can access openly and freely so
1 of the tools that we developed
at project noise web C so basically what web safe bus is it takes a hazard not which tells us where it's going to have I mean where it's going to however on hazard for this example this is a flood not it does as well is going to have floods In the case of uh extreme rain and then it all relays that lead and other map and expose from in this case this is a population density map it does us where people live and then sex intersects this through maps and gives us some analysis that we think would be valuable when it comes to disaster management there and so let's see if stands for
based scenario assessment for emergencies it is included in it's 1 of the tools that we include in our on the our website where actually working on the version 2 of the project no website that it's this is a screenshot of it so we have the other features there but would save is this 1 they later we're going to have as I said a while ago there will be at the so in the next session and its state continuous improvement under no initiative and there will be more details regarding this website so for now that's falls on safe web safe is built with our free and open source software for geospatial it is up to would like to meet the needs of ommunity considering their effects of a particular has so let's go back to the last
slide you can see here it tells us what percentage of the population of the total population will be hit will be affected by the flat the thought of 1 million and 100 25 thousand says 606 thousand would be affected and then it doesn't the uh how many of these people will be in the different and hazard areas for this example it's a flat map does as how many people will be in this um flood height these are different than the heads so Fred means um it's just above your job the average Filipino height for instance of this In many so that 197 thousand will be flooded up to the needs and then at low hazard areas means of it will be a little bit about their food 184 thousand and then also it provides you with an estimation of the needs that there would be a consuming when you evaluate the so 100 1900 when 1 thousand 696 1 I and variance 696 thousand 800 kilograms of phrases we need here laughter at these people and so on
so project null and the world bank partners in the development of web C initially after the funding from the World Bank and project no initiated some other improvements for web save and that this now backed up by subset web safe aims to a of government units in their response assessed so as I said it of the version to the Web site of project no so before we proceed with my slides and I would like to show you members of the and and
the it hooked on so long as you go take a look at the website
site the yes
pick so we haven't about officially launched this version 2 so it's in that that the face you asses it for the best thing it's bet that that no other dynasty that got that pH but the on national and access this website so here are you can access let's see if it this by clicking this cycle and to use it you're going to have to choose do here's the hazard layer and expose so let's take a look at where I live in Manila so we have so I am sorry this drop down on our gives you all the
hazard layers that we have
prepared we're continuously generating hazard maps for this right now we only have that has much but we're looking at also providing some hazard maps for storm surge and landslide so let's take a look at menu so and that's the flat map for menu this over the the population density map of Manila these maps are all generated a project now we have components that are focused on knowing the generation
of this map so here's the sample report of web C so showing you this so
legal and the stringent so that's how you use web C along with other
features and then project no except
the so there I like to go through
that there are different technologies that we use in the development and maybe provide a brief explanation of and what it does but so
1st in a safe it's a is subcutis blocking betrayed by phone and the core calculation capability of web C for users other the inessive API so you can that check the code for this With this in injured have next we use Tornado whether it's on the web server that also be with by Python it uses non-blocking and synchronous and technology which enables Del Webb up to a home a date uh requests a synchronous for the
database we use a possibly secure the I'm database of the different hazard maps available and their locations next we
have server through served that uh maps and that are being displayed and hazard maps and exposure maps are all stored in and USA use open there's the
further or relating the maps displaying the maps in the browser the and
for building the web of we use a Angular JS as the framework and some bootstrap for responsiveness
and other technologies we use for the inputs for the generation of hazard maps you so to the and we extract data from OpenStreetMap for the building footprints I don't think I have shown you the building footprints the feature so this go to that so you
can this yeah so I'll
show you know building footprints for a couple of minutes the place where supine so playful when hi and hit so and
these are building building footprints extracted let's wait for it to load from and OpenStreetMap the
so the limitation here is that OpenStreetMap uh continuously updates its data so we need to also regularly checked for new data a so that's right so that's 1 of the limitations there and as you and see there's a part of the of the place that does not have some buildings from it so all we have GS specialists who regularly check of intriguing up for it Michael it will also give you give us our and analysis when it comes to the infrastructure most of the the so from calculation for the building footprint states a little bit longer then when the using a population density map
but here it is so it does that out of 30 thousand 416 buildings 10 thousand 124 will be affected by by anything of those have be high hazard and so on In the future this is under development as I said uh it's still that the face we will be able to release the different um building types so that the disaster managers can see i which of buildings will be highly effective so alone and that's
it that's website think you'd like fj thank you the released any questions for Mr. Iacocca yes the roadmap for a club safe John working in the world bank was giving everybody and we're just working with ecodesign team I'm just curious what would you guys have coming up yeah I know so right now as I said a while ago we're looking at and providing more hesitates right now we have a hazard maps for floodings but we're generating more for even for a storm surges unless it's also well we are integrating additional information from and the Philippine Statistical Authority and a regarding the census of so we can provide some age groups and genders things in the report so we can see how many children are affected but it is this this has and also a where improving their is experience so uh and reports so that it can be easily understood that the users thank you is and some Canadian with through the Canadian NGO bomb how closely those do you work with the national local government level very close to paraphrase also and not be regularly and get visitations from long government meters and also we conducted a think twice every 2 weeks and some so I some lectures to and explain how they can use it as so we we have partnerships with the deity that's the Department of Internet interior yeah and this layer let's say when we release it we hope that the energy will be and using it as 1 of the main tools for the error and in the Philippines OK so that's helpful I think I I a lot of times when I worked there find there's a disconnect between the local level and the national government agencies a matter of coordination communication and so on so I thoroughly encourage you to communicate with the local governments and so on we agree we also noticed that and we have a component that is dedicated for the communicating the different information that we think it will be unnecessary during disasters and steady were questions historical yes from the FIL thank you for the interesting presentation because I have was a literal for what reasons such kind of a similar to so I'm wondering when you go go league of in the west side to you were calling them these on the fly welfarism or when you choose to silly a school or do you cook make them intensity of the 1 you President painting that don't and yet no calculation happens in the pattern so we use in a safe for the calculation capabilities it's in Python from these so it when the user chooses the hazard map and exposure map uh and this information is sold to the backend server room and then about and calculated and then throws the result to the front and so he's done with gain oppose Janez Deacon please yet we use a database for yeah database of the different hazard maps available yeah positive it thank you so they were questions the OK so thank you Mister call this around given much rather plastic

Abstract WebSAFE (Web-based Scenario Assessment for Emergencies) is an impact assessment tool used in the Philippines to calculate the needs of a community considering the effects of a particular hazard. DOST-Project NOAH and The World Bank partnered in developing WebSAFE to increase the country's disaster preparedness measures. Using Project NOAH's LiDAR and IFSAR-based flood, landslide, and storm surge hazard maps for the whole country and OpenStreetMap information, WebSAFE aims to aid Local Government Units in their response toward disasters. A community of volunteer mappers for disaster risk reduction, called MapaSalba (a local pun that loosely translates to "to save using maps"), was also started last year to encourage local participation and enrich the OpenStreetMap database. All of these efforts were shown to contribute to the Philippines's generally improved disaster preparedness and over-all decline in human and economic losses from disasters for the past two years. WebSAFE uses InaSAFE API, a free and open source plugin for QGIS software. With the help of its developers, we modified and developed it into a web application. Project NOAH envisions a disaster-free Philippines where communities are empowered through open access to accurate, reliable and timely hazard and risk information.
