Spatial database management has become an important subarea
of current database research. Research in this area is often
characterized by interdisciplinary cooperation: computer
scientists work with geographers andenvironmental
scientists to provide better access to spatial databases of
steadily increasing size. After the First Symposium on Large
Spatial Databases (SSD '89) was held in Santa Barbara,
California, in 1989 (and its proceedings published as Volume
409 of this series), a second symposium (SSD'91) was held in
Zurich, Switzerland. This proceedings volume contains the
papers presented at SSD '91. Topics include spatial data
models and access methods, performance studies, geometric
algorithms, spatial query languages and user interfaces,
geographic information systems, and object-oriented
techniques.
