interactive web-based, GIS-enabled cancer atlas is a prototype,
designed as a model for implementation of atlases to support government
cancer control activities. This model integrates symbolization and
design principles from print cartography, interaction strategies
from exploratory geovisualization, and web-map/web-feature service
advances from GIS. The atlas has been implemented using a client-server
architecture. It leverages two open-source GIS tools, PostGIS (as
the system database) and GeoServer (to connect the database to the
client mapping application). The client mapping
application has been built in Macromedia Flash.
This research and development effort aimed to design
and implement a model web-atlas to support cancer surveillance and
control activities undertaken by public health professionals (figure
1). The research integrates perspectives and technologies associated
with interaction strategies for exploratory geovisualization, interactive
atlases, and web-map/web-feature services.
