| Zusammenfassung |
| Remote sensing is increasingly used to assess disaster damage, traditionally
by professional image analysts. A recent alternative is crowdsourcing by
volunteers experienced in remote sensing, using internet-based mapping
portals. We identify a range of problems in current approaches, including
how volunteers can best be instructed for the task, ensuring that
instructions are accurately understood and translate into valid results, or
how the mapping scheme must be adapted for different map user needs. The
volunteers, the mapping organizers, and the map users all perform complex
cognitive tasks, yet little is known about the actual information needs of
the users. We also identify problematic assumptions about the capabilities
of the volunteers, principally related to the ability to perform the
mapping, and to understand mapping instructions unambiguously. We propose
that any robust scheme for collaborative damage mapping must rely on
Cognitive Systems Engineering and its principal method, Cognitive Task
Analysis (CTA), to understand the information and decision requirements of
the map and image users, and how the volunteers can be optimally instructed
and their mapping contributions merged into suitable map products. We
recommend an iterative approach involving map users, remote sensing
specialists, cognitive systems engineers and instructional designers, as
well as experimental psychologists. |
