1. INTRODUCTION (2) The need for a map
? ? ?? ? ? ? ?
? ? ? ? ? ?? ?
A map for answering questions related to: location, casualties, damage zones
1. INTRODUCTION (3) The answer can depend in the level of detail of the base information.
A big granularity:
the level of detail of the base information.
A
(example)Cities :- The number of people
B
A - The number of people - Amount of houses.
CBut when attempting to predict and estimate losses due to natural hazards
f- Demographic information- Buildings stock inventory- InfrastructuresInfrastructures
1. INTRODUCTION (4) Problems when reaching this kind of information:this kind of information:
- Information is related with protected information.Information is related with protected information.- Created for taxes goal not thinking in Risk.- There a large numbers of initiatives promoting SDI but only in a
few cases natural hazards domains is included into them (Schmitz et al.), that's mean s that if the information is available it is no often through out standardized way for software accessingoften through out standardized way for software accessing
1. INTRODUCTION (5)
THE CHALLENGETHE CHALLENGE- Analysis and design of a set of OWS using
the available resources, as promoted by SDI initiatives.- Identification of services to reproduce the experience in other
places.
THE MOTIVATIONTo propose a distributed and standardized visionfor providing data access and information processing for estimationfor providing data access and information processing for estimation and presentation of the damage caused by natural hazards.

PAGER: Prompt Assessment of Global Earthquakes for ResponseDeveloped by the USGS
This review hasn't been comprehensive
Evaluates the number of people, cities and regions exposed to a powerful earthquake in all over the world.
Developed by the USGS.

Why doesn't PAGER estimate loss of life or property?in order to estimate building damage or human casualties, it would be necessary to use databases of building inventories...No such database exists on a global scaleto use databases of building inventories...
2. RELATED WORK (4)
GEM: Global Earthquake ModelIntends to be an independent, consistent standard of worldwide application for calculation of risks, estimate of loss by an earthquake and communication of hazards. (2013 the first complete global earthquake model).
2. BACKGROUND (5)
CAPRA: Central America Probabilistic Risk Analysis
CAPRA is defined as an information platform to support risk management for decision making in natural disasters.
i l t O G N d- implements OpenGeoNode- Uploading of data and metadata in the GeoNode- OGC standardized services WMS, WFS and CSW
- Lack of direct connection to the data sources.

4. METHODOLOGY
For designing the proposal a system architecture the followingsteps were done.
1) Analysis - Earthworm and Seisan) yfor implementing services of warning and notifications.
2) S d B ildi l i Al i h /P2) Study - Building typologies Algorithms/ProgrammesResistance capacity curves / building of the inventory.
3) Study - SELENA APIfor publishing their functionalities with OWS.
4) Analysis - SELENA Input/Ouput

5) Analysis – RISeRISe APIfor publication of its functionalities in a standardized way.
6) Analysis - RISe input /output
7) Data harmonization (building inventory ) for the cadastraldata base.
8) Modelling of the sequencing and arrangement of the execution8) Modelling of the sequencing and arrangement of the executionof services published for processing and warning on the basisof the available data.
9) Design of a system architecture connecting all standardizedresources through the Internetresources through the Internet.

1. The main contribution of our work has been the proposalstandard geoservice architecture to generate damagestandard geoservice architecture to generate damageestimation maps from seismic events.
For the design of these services we have tried to reuse to theutmost existent resources..utmost existent resources..
6. CONCLUSIONS AND FUTURE WORK (2)
2. The application of standardized technologies to interconnectautonomous systems ensures their interoperability.y p y
3. The proposed architecture keeps the roles of actors/agenciesand people.and people.
4. An issue that will require a coordination effort is data modelspecification to be offered by the municipalities with thecadastral data.
5. The use of geo-referenced syndicated news (GeoRSS) for tupublish the seismic events.
