The role of information systems (IS) as representations of real-world systems is changing in
an increasingly digitalized world, suggesting that conceptual modeling is losing its …

In this paper we present a formal framework for modelling a trajectory data warehouse
(TDW), namely a data warehouse aimed at storing aggregate information on trajectories of …

The increasing availability of geo-referenced data has increased the need to enrich OLAP
with spatial analysis, leading to the concept of Spatial OLAP (SOLAP). The conceptual …

With the increasing availability of locating and navigation technologies on portable wireless
devices, huge amounts of location data are being captured at ever growing rates. Spatial …

Spatial data warehouses (SDW) rely on extended multidimensional (MD) models in order to
provide decision makers with appropriate structures to intuitively explore spatial data by …

Combining national forest inventory (NFI) data with auxiliary information allows downscaling
and improving the precision of NFI estimates for small domains, where normally too few field …

Large volumes of geospatial data are being published on the Semantic Web (SW), yielding
a need for advanced analysis of such data. However, existing SW technologies only support …

In the last years, extending OLAP (On-Line Analytical Processing) systems with spatial and
temporal features has attracted the attention of the GIS (Geographic Information Systems) …

Abstract In recent years, Open Street Map (OSM) has evolved into a highly popular
geospatial system. The key of success of OSM is that OSM is open to absolutely everyone …

Recently, the volume of available spatial data increased tremendously. For instance, in
November 2013 NASA announced the release of hundreds of Terabytes of its earth remote …
