Best way and times to contact during RHoK 2.0 Dec 4/5 2010: I'll be at Rhok 2 Jakarta - with bells on...
Risk and impact modelling are required by governments around the world to reduce loss of life and financial loss caused by disasters. These analyses in general are static documents/maps built in silos and forgotten on shelves. What is needed is a simple, easy-to-use and dynamic way for disaster managers to combine the disparate datasets about hazard levels and exposure, calculate impacts and effectively communicate the results on-line.

A proof-of-concept was developed based on initial work at RHoK #1 in Washington. Now is the time to build this thing properly and make sure it is well integrated with the Geonode and OpenGEM projects. The link to the proof-of-concept is at http://www.aifdr.org/projects/riat
A provincial disaster manager (BPBD) connects to a web tool that presents a map of Indonesia. In addition to basic map interaction (pan, zoom, identification) this web page allows them to:
- select a hazard map layer, an exposure map layer;
- based on the choice of hazard and exposure select a damage function from a drop down list (- this list should be populated dynamically as the choice of hazard and exposure changes)
- press a button to send these layers and damage model off to a piece of code (an impact model) to combine them (it is the API and the selection process that is the issue here - the complexities for the impact models will be the next component)
- automatically import the outcome of this calculation back into the map
- allow a user to import their own exposure data from a simple txt file (say csv) and then have this appear in the map and the list of exposure datasets.
This tool has to
- look good
- be intuitive and easy to use (perhaps moving towards a "wizard")
In general, impact assessments are about determining the level of hazard that a specific piece of infrastructure or exposure (house, school, hospital, bridge, road, etc) experiences and then using a damage curve that is specific to the hazard and exposure type to determine the level of damage. These results are then typically aggregated according to some boundary (province, district, sub-district etc.). If this data is stored on-line, an API is needed that will allow hazard and risk modelling software to acquire, process and publish such data sets.
The API should provide a means for extracting vector and raster data from spatial servers (such as the architecture provided by GeoNode) into Python where computations reflecting the desired impact analysis are carried out and then publish resulting spatial data on a spatial data server all from within the Python program. The API should provide this data in appropriate data structures that allow for manipulation, computations and analysis. Python is suggested as it is well suited and widely used in modelling.
This API can underpin specialised applications that will codify impact assessments for a range of different hazard levels and exposure datasets.
Impact Models - spatial interpolation
When the above BPBD staff press their button, we need to be able to:
- quickly and easily interpolate the value of hazard (either defined as a grid (raster) or a series of polygons (contours) at specific and arbitrary points)
Impact Models - aggregation
When the above BPBD staff press their button, we need to be able to:
- select a fourth layer that is a spatial boundary (say district or sub-district boundaries) and aggregate the impact across these boundaries to be able to then differentiate between these layers
- instead of displaying the original losses, only the aggregated losses should be loaded and displayed on the map
OpenGEM is working on something along the same lines. This project was started at RHoK #1 in DC, June 2010.
This project is sponsored by the Australia-Indonesia Facility for Disaster Reduction and will support government requirement to produce and deploy risk assessment guidelines nationally.
A proof-of-concept was developed based on initial work at RHoK #1 in Washington. Now is the time to build this thing and make sure it is well integrated with the Geonode and OpenGEM projects.
