چکیده

The integration of Geographic Information Systems (GIS) and On-Line Analytical Processing (OLAP), denoted SOLAP, is aimed at exploring and analyzing spatial data. In real-world SOLAP applications, spatial and non-spatial data are subject to changes. In this paper we present a temporal query language for SOLAP, called TPiet-QL, supporting so-called discrete changes (for example, in land use or cadastral applications there are situations where parcels are merged or split). TPiet-QL allows expressing integrated GIS-OLAP queries in an scenario where spatial objects change across time.

Toward Better Support for Spatial Decision Making: Defining the Characteristics of Spatial On-line Analytical Processing (solap)

To exploit the full potential of the spatial and temporal dimensions of a data warehouse, new tools are needed. It has been shown that OLAP possesses a certain potential to support spatio-temporal analysis. However, without a spatial interface for viewing and manipulating the geometric component of the spatial data, the analysis may be incomplete. A new category of OLAP tools, SOLAP (Spatial OL...

SOLAP technology: Merging business intelligence with geospatial technology for interactive spatio-temporal exploration and analysis of data

To support their analytical processes, today's organizations deploy data warehouses and client tools such as OLAP (On-Line Analytical Processing) to access, visualize, and analyze their integrated, aggregated and summarized data. Since a large part of these data have a spatial component, better client tools are required to take full advantage of the geometry of the spatial phenomena or objects ...

Solap: a New Type of User Interface to Support Spatio-temporal Multidimensional Data Exploration and Analysis

It is well known that transactional and analysis systems each require a different database structure. In general, the database structure of transactional systems is optimized for consistency and efficient updates while the database structure of analysis systems is optimized for complex query performance. Non-spatial data are reorganized in data warehouses in order to support analysis and decisi...
