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??

Open Data Movement

Open Data Applications

Spatial Data Infrastructures and Open Data

- About making data available- Data should be freely available

Two sides of the same coin:

Everything can be mapped!!

80% of the data has a spatial component

Data exploration and analysis through spatial operations

Spatial Data Formats

Programming languages

GIS Desktop Tools

Spatial Databases

Web Mapping Clients

Data processing...

Data mining tools: Business Intelligence

Spatial ETL ToolsExtract, 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

The umbrella...

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

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.
