Abstract—This work is based on the connection between two
important and growing fields in computing:
Computer-Supported Cooperative Work (CSCW) and
Geographic Information Systems (GIS). In this kind of system is
important the concept of teamwork, due to the complexity and
size of the projects underway around the world, where there
may be situations where users need to access, modify and share
spatial information in real time from different geographical
locations, and also perform classifications, georeferencing and
other activities synchronously. In the study summarized in this
paper, was conducted a process of requirements engineering
about the collaborative work in the TerraAmazon system, a
multiuser workspace, developed with the open source
geoprocessing library called Terralib, used in major important
projects of urban and environmental research institutions, like
the National Institute for Space Research (INPE). With regards
to the requirements elicitation technique, it was made a kind of
half-open interview with introspection and discussion of
scenarios with photo interpreters (potential users) from INPE
(The Amazon Regional Center) and Brazilian Enterprise for
Agricultural Research (EMBRAPA). The requirements are
validated and solutions are proposed using important concepts
in CSCW, like awareness, coordinators and communicators.
Finally, the conclusions are presented.
Index Terms—Computer-supported cooperative work,
