| Abstract: | The purpose of this study was to develop a methodology for assessing the usability of Earth Observation data for different phases of disaster management. Another aim was to identify the user groups in disaster management and finally to establish the purpose of the products. Case study application of the methodology on sample datasets produced in response to the Haiti 2010 earthquake was also examined in the study. Survey and literature review were used to identify the necessary inputs of the methodology. Relevant literature review was carried out to identify user groups and supported by information gathered from survey. Six different data types were explored to establish the purpose of datasets. The survey was done on two user and producer organizations who participated in the response to 2010 Haiti earthquake. The information gathered was used to group related parameters forming major inputs and information containers were created for user requirements, data specifications, comparison platform and ranking. These major inputs were logically aggregated to form the first phase of the methodology to be implemented by the expert and the second part to be carried out by the end-user. The results were that Earth Observation data are made for direct use when fully processed without possibility of manipulation and indirect use when semi processed with possibility of manipulation. The user groups were identified into major categories of planners, responders and researchers. The application of the methodology resulted into common framework of comparing data specifications against user requirements known as ‘quality information template’. The principal conclusion was that usability of disaster data can be improved by expert evaluation and rating and making the report from experts available to the user through a common interactive platform where they can chose potential datasets and subject them to ranking. Keywords: Data quality, quality information template, usability, disasters, ranking |
