Talk di Juan Arevalo & Marco Giacomassi | Drupal Day Roma 2011

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!

    • Data is everywhere...
    • Inspire Directive • Infrastructure for spatial information in Europe to support Community environmental policies:- Decreto Legislativo 32/2010 di recepimentodella Direttiva Inspire - Metadata, interoperability, Web services,standards, data specifications, etc..
    • Is it worth it?? Cost:Total direct cost: 1.5 M € (76%Human Resources)Period: 2002-2006 Benefits:Internal efficiency benefits: 500hours per month (30€ hour)Recovery cost: 6 months
    • Open Data Movement
    • Open Data Applications
    • Spatial Data Infrastructures and Open Data Two sides of the same coin: - About making data available - Data should be freely available
    • 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 Tools Extract, automate and define a data flow processTranslate spatial data into the format that the endconsumer 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 andcoordinate 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
    • SOLAP Clients
    • SOLAP Clients
    • Spatial OLAP & Drupaldata feed
    • Spatial OLAP & Drupaldata feed S. ETL
    • Spatial OLAP & Drupaldata feed workflow management S. ETL DB S. CUBE
    • Spatial OLAP & Drupaldata feed workflow management frontend S. ETL DB S. CUBE geojsp
    • Conclusions1. Huge amount of data with a spatial component that needs tobe explored and analysed.2. Availability and maturity of open source technologies andKnow-how: OLAP and Geographical Information Systems(GIS).3. Spatial OLAP merging OLAP and GIS via Open Source Tools.
