It is, however, a complicated task to rapidly generate a complete and comprehensive situation map of a disaster area, particularly due to the centralized(More)
During emergency response, individuals observe only part of the picture, sharing of information is needed to get the required complete picture. The aim of our study is to get insight in the collaborative mapping process in order to derive requirements for a map-sharing tool.

It presents the results of a controlled field experiment that compares a new disaster response model involving civilians participating with smartphones with the traditional(More)
