data warehouse architecture for gis applications
Geo-data sets are built for use in geographical information systems (GIS). The data is modeled to suit the needs of data entry and visual representations. They are optimized for simplicity and speed of modification. These models do not lend themselves to efficiently produce enterprise reports. Hence, Geo-data sets can be very challenging to query and analyze. In this paper, we create a data warehouse (DW) for a geo-dataset to facilitate report generating processes. A data warehouse is attractive as the main repository of an organization's historical data and is optimized for reporting and analysis. For better understanding of the developed architecture, we cover the data warehouse construction process as well as the enterprise data model
