We propose a definition of a spatial database system as a database system that offers
spatial data types in its data model and query language, and supports spatial data types in …

3D geo-database research is a promising field to support challenging applications such as
3D urban planning, environmental monitoring, infrastructure management, and early …

Topological relationships between spatial objects represent important knowledge that users
of geographic information systems expect to retrieve from a spatial database. A difficult task …

During the last two centuries population density has increased considerably making land
use more intense. This trend has caused a growing importance of ownership of land, which …

In the field of spatial information systems, a primary need is to develop a sound theory of
topological relationships between spatial objects. A category of formal methods for …

There are two major challenges for a high performance remote sensing database. First, it
must provide low latency retrieval of very large volumes of spatio temporal data. This …

Existing geoprocessing technologies lack the modelbase management capabilities needed
to construct dynamic simulation models of geographical systems. A geoprocessing …

The term “reactive data structures” refers to approaches to the problem that maps (or other
geographic information systems (GIS) display media) of different scale and topical focus are …

Sistemas de Informação Geográ ca, ou abreviadamente sigs, são sistemas de informação
cons truídos especialmente para armazenar, analisar e manipular dados geográ cos, ou …

This paper describes the design and implementation of Paradise, a database system
designed for handling GIS type of applications. The current version of Paradise, uses a client …
