damage, together with major effects that are<br />

obscured from overhead viewing such as soft storey<br />

collapses. A detailed street-view perspective<br />

captured using tools like the VIEWS data collection<br />

system designed by ImageCat<br />

(www.imagecatinc.com ) in collaboration with<br />

MCEER (www.mceer.buffalo.edu), fills these<br />

in<strong>for</strong>mation gaps.<br />

VIEWS is a notebook-based field data collection <strong>and</strong><br />

visualization system. It integrates pre- <strong>and</strong> postdisaster<br />

remote sensing imagery with real-time GPS<br />

(Global Positioning System) readings <strong>and</strong> map layers,<br />

<strong>and</strong> operates in conjunction with a high-definition<br />

video (HDV) digital camera <strong>and</strong> digital video<br />

recorder. The VIEWS system was first deployed <strong>for</strong><br />

earthquake field reconnaissance following the<br />

December 2003 Bam (Iran) earthquake (Adams et<br />

al., 2004), <strong>and</strong> has since been utilised following<br />

events including the Indian Ocean tsunami <strong>and</strong> the<br />

2008 Wenchuan earthquake.<br />

Conclusion<br />

Within the risk management arena, to date, the<br />

research focus of remote sensing <strong>and</strong> GIS has<br />

generally been on engineering aspects of urban<br />

inventory. Nevertheless, faced with increasing<br />

human losses from natural disasters as urban<br />

populations exp<strong>and</strong>, the global research community<br />

is beginning to recognise the potential of these<br />

technologies <strong>for</strong> estimating socio-economic<br />

parameters.<br />

It can concluded that with the goal of minimising<br />

future human suffering <strong>and</strong> loss, in<strong>for</strong>mation on<br />

population <strong>and</strong> its distribution is one of the most<br />

crucial parameters <strong>for</strong> resilient disaster<br />

<strong>Management</strong>. The case study of Ahmedabad<br />

demonstrates that population data <strong>for</strong> different<br />

spatial levels, as well as in<strong>for</strong>mation on the data<br />

source <strong>and</strong> associated metadata are scarce,<br />

expensive or unavailable. Initial results indicate that<br />

a tiered conceptual framework provides a<br />

transparent <strong>and</strong> consistent system <strong>for</strong> estimating<br />

population at different levels. Implementation of the<br />

framework described is currently being completed<br />

<strong>and</strong> initial results are expected in early 2010.<br />

Remote sensing <strong>and</strong> GIS are also increasingly being<br />

used <strong>for</strong> inventory data development <strong>and</strong> disaster<br />

response within the re/insurance <strong>and</strong> humanitarian<br />

located in Universities, Research Organisations <strong>and</strong><br />

Companies around the World.<br />

in<strong>for</strong>mation systems <strong>for</strong> first responders such as<br />

InLET <strong>and</strong> the Virtual <strong>Disaster</strong> Viewer (VDV), which<br />

enables rapid data development <strong>and</strong> sharing in the<br />

direct aftermath of an event. Initiatives such as the<br />

International Charter provide remote sensing-based<br />

situation assessment <strong>and</strong> damage in<strong>for</strong>mation to<br />

authorised users <strong>and</strong> nations affected by disasters.<br />

For a complete picture, aerial <strong>and</strong> satellite imagery<br />

may need to be augmented with street-view<br />

in<strong>for</strong>mation acquired using systems such as VIEWS.
