DESCRIPTION
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. Please come to learn more about it!

Thinking spatially with your open data“Spatial data deluge: please bring me an
umbrella!”Juan Arévalo, Marco Giacomassi
Data is everywhere...
- Decreto Legislativo 32/2010 di recepimento della Direttiva Inspire
- Metadata, interoperability, Web services, standards, data specifications, etc..
• Infrastructure for spatial information in Europe to support Community environmental policies:
Inspire Directive
Cost:
Total direct cost: 1.5 M € (76% Human Resources)Period: 2002-2006
Benefits:
Internal efficiency benefits: 500 hours per month (30€ hour)Recovery cost: 6 months
Is it worth it??

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.
