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 />
