  1. The WISDOM Information SystemArchitecture and potential for a Spatial Data Infrastructure (SDI)

  2. The WISDOM Information System Introduction • WISDOM • How it looks like • Features Architecture • Open Source Software Stack • Architectural Overview • Standards Potential for a Spatial Data Infrastructure (SDI) • Vietnam NSDI (VNSDI) • Potential for a Spatial Data Infrasructure

  3. Context WISDOM Water-related Information System for the Sustainable Development Of the Mekong Delta in Vietnam • End of the 2nd phase: end of 2013 • 5 years of development • first a demonstrator version to get feedback • suggestions went into further development • Online available (free registration) • http://wisdom.eoc.dlr.de/Elvis(Server located in Germany) • http://wisdom-vn.org/elvis (Server located in Ho-Chi-Minh-City) • Project Homepage: www.wisdom.eoc.dlr.de

  4. How it looks like

  5. Features • Online tool for geoscientific data exchange and information platform • User Management (Register, Administer, User Rights Management) • Multilingual GUI / Multilingual Metadata • Data Search (Geodata / Literature / Contacts) • Visualize data on top of a base map • Data Upload • Data Download • Predefined Maps • View Field Data Photos • Visualize Sensor Measurement Data as a Diagram

  6. Open Source Software Stack

  7. Open Source Software Stack WISDOM Environment KVM Virtualization Environment

  8. Architecture OGC Standards Offer Service Consume Service Server Client Manage Data User Interface

  9. Architecture

  10. Standards • WMS (OGC Web Mapping Service) • UMN Mapserver + TileCache • SLD (Styled Layer Descriptor) • WPS (OGC Web Processing Service) • Standard to wrap a (geospatial) process and make it accessible via the internet (any process programmed in Matlab, IDL, Java, Python, etc.) • CSW (Catalog Service for the Web) • Metadata profile follows ISO standards • Translatable • Managing of Time Series Data • Keyword search • ISO 19115/19139 Metadata

  11. Spatial Data Infrastructure Definition in legal document of the US Federal Government (1994) • SDI as a minimum infrastructure, includes applications, standards, technology and institutional governance necessary for effective and efficient spatial data and services management within or across organizations. • SDI on different levels (e.g. Europe: INSPIRE, National: GDI-DE) • The concept of National SDI (SDNI) is now being universally called the Spatial Enablement of Governments and Societies (UN Declaration from Kuala Lumpur, 2011) Source: http://www.asiageospatialforum.org/2012/proceeding/Hoang%20Lam%20Son.pdf

  12. Vietnam NSDI (VNSDI) • Spatial data set • spatial data, framework spatial data and meta-data • Standards • Standard of spatial data contents, Standard of data exchange, Standard of meta-data and Standard of data services • Access to data • Data Discovery, Data Access and Data Process • Technology • Hardware and Software Equipment, Data Communication Network • Policy - Legislation • Mechanism, Policy and Legislation regulated by the State • Organization Institution • including Organizations Arrangement and Relationship between Organizations • Partnership • Investment Funding, Human Resources Development, Public Awareness Raising, Scientific Research and International Cooperation) Source: http://www.asiageospatialforum.org/2012/proceeding/Hoang%20Lam%20Son.pdf

  13. Potential for a SDI Pros • availability • support of Standards • Service Orientated Infrastructure • adoptable for other regions • easy to transfer to other server due to Virtualization • platform for further development Cons • no synch between instances of the system • performance must be tested for larger scale application
