  In this paper we describe a proposal for information organization for
computer supported cooperative work, while working with spatial information. It
is focused on emergency response plan construction, and the requirements
extracted from that task. At the centre of our proposal is the analysis of the
structure of the cooperative workspace. We argue that the internal information
representation should follow a spatial approach, tying the structure used to
manage users with the structure used to manage information, suggesting the use
of different spaces to represent the information. The gain we expect from this
approach is the improved capacity to extract information on how people are
cooperating and their relationship with the information they are working with.
The ideas are introduced while focusing on real life emergency planning
activities, where we discuss the current shortcomings of the cooperation
strategies in use and propose a solution.
