The Open Data movement is now moving a step forward, many governments, institutions and business have recently started the process of making information available to citizens and customers. Data is now seen as a powerful instrument to increase transparency in public administration and business on policies. About 80% of this information has a spatial component that is not entirely exploited yet. A range of open source solutions are now available to address this challenge, in this session we will explore their potential and possible applications. The so-called “data deluge” is here.. but we can build good umbrellas.
3. Inspire Directive

17. Spatial ETL Tools
Extract, automate and define a data flow process
Translate spatial data into the format that the end
consumer requires
Load and integrate disparate data into a spatial database
Document your processing data steps
Execute process in a Parallel Computing Environment
Restructure the data into the required data model and
coordinate system
19. Spatial data cubes
- Store geometry in a data cube
- Spatial query language (MDX)
- View agreggated data from different perspectives
- Fast retrieval and anlysis of data

26. Conclusions
1. Huge amount of data with a spatial component that needs to
be explored and analysed.
2. Availability and maturity of open source technologies and
Know-how: OLAP and Geographical Information Systems
(GIS).
3. Spatial OLAP merging OLAP and GIS via Open Source Tools.
