This research outlines a case study in Aceh,<br />
Indonesia, in the aftermath of the December 2004<br />
Indian Ocean Tsunami. The main aim of the study<br />
was to identify methods to determine <strong>and</strong><br />
quantifiably assess the benefit of the use of a specific<br />
spatial data set in disaster recovery, <strong>and</strong> it follows on<br />
from an earlier study implemented in 2007.<br />
The earthquake <strong>and</strong> subsequent Tsunami devastated<br />
wide areas <strong>and</strong> hundreds of communities across<br />
Aceh. The available topographic data (i.e. relief <strong>and</strong><br />
the spatial location of man-made <strong>and</strong> natural<br />
features) was approximately 30 years old <strong>and</strong><br />
contained significant errors. Immediately after the<br />
Tsunami there was a large dem<strong>and</strong> <strong>for</strong> new<br />
topographic <strong>and</strong> spatial data to support the<br />
rehabilitation <strong>and</strong> reconstruction activities,<br />
including; the needs of the national Government<br />
Figure 1: One use of the high resolution aerial imagery was to correctly reference spatial<br />
plans <strong>for</strong> the reconstruction of villages devastated by the Tsunami. Plans <strong>for</strong> the<br />
reconstruction of the village of Cot Paya are shown.<br />
