1
6th GEO Capacity Building Committee Meeting TASK
REPORT CB-07 01e Open Source Software
  • João Soares
  • vianei_at_dsr.inpe.br
  • INPE - BRAZIL

2
Background and Objetives
  • Encourage the use of OSS across EO value chain
  • Inventory of OS solutions within GEO
  • Post the inventory into the Web Portal
  • Encourage development of OSS solutions by
    building on existing efforts
  • TerraLib and TerraView as starting GIS platforms
    (integrated Earth Observation and GIS data)

3
Empowering people with geo technologies
  • The white-box model
  • People
  • Learning by doing x learning by using
  • Methods
  • Translate concepts into working procedures
  • Software
  • Provide adequate support for data analysis and
    integration

results people methods software
4
Why TerraLib and TerraView?
  • Technology has changed
  • Previous generation of GIS
  • Built on proprietary architectures
  • Interfacefunctiondatabase monolithic system
  • New generation of object-relational DBMS
  • All data will be handled by a DBMS
  • Standardized access methods (e.g. OpenGIS)
  • Users can develop customized applications

5
Free and Open Source Software for Geo
  • FOSS has established itself as a viable
    alternative to proprietary software
  • Four fundamental freedoms run, study,
    redistribute and improve the software
  • Benefits cost reduction, community, innovation,
    freedom, enjoyment,...
  • FOSS for Geo include
  • Web mapping
  • Desktop applications
  • Geospatial libraries
  • Interoperability

6
Different GIS architectures are needed
  • Desktop GIS
  • Single-user
  • Emphasis in friendly interfaces and analysis
    functions
  • Distributed GIS
  • Multiple users
  • Data sharing
  • Emphasis in access and simultaneous control
  • Web services
  • Using the Internet to disseminate data and
    services
  • Emphasis in usability and flexibility

7
TerraView
  • GIS that allows the construction, visualization
    and analysis of a TerraLib database
  • FOSS LGPL
  • It can be customized by Plugins

8
TerraLib
  • A library to develop geographical applications
  • Open Source Policy LGPL
  • Open Protocols
  • Use DBMS
  • Allows users to customize a solution

9
Applications built on TerraLib
  • Cadastral Mapping
  • Improving urban management of large Brazilian
    cities
  • Public Health
  • Spatial statistical tools for epidemiology and
    health services
  • Social Exclusion
  • Indicators of social exclusion in inner-city
    areas
  • Tools to help decision makers to create public
    policies for social development
  • Land-use change modeling
  • Spatio-temporal models of deforestation in the
    Brazilian Amazon
  • Emergency action planning
  • Oil refineries and pipelines (Petrobras)
  • Building partnership and networks for operating
    under an agreed agenda

10
Milestones achieved to date
  • TerraLib programming tutorial in English -
    guides the user through general concepts of
    GeoInformation, spatial databases and the
    particularities of TerraLib.
  • First experience of an e-learning course in
    TerraLib Programming carried on in the context of
    eduGI.LA project (Network for GI science
    education Latin-America, funded by the European
    Commission under the ALFA program).
  • Started the inventory of OS in GIS
  • Establishement of the Open Source Geospatial
    Foundation (INPE one of the sponsors).
  • TerraView tutorial in English for basic use,
    providing a sample data set.
  • Marlin visualization tools for CBERS users

11
Expected Milestones for 2008
  • Identify OSS solutions for use in GEO
  • Building on existing inventories
  • Develop TerraView and TerraLib training
    material, courses, tutorials and documentation
    for both programmers and end-users available (in
    English) and develop specialized training
    material for e-learning.
  • TerraView Site in English
  • Lauching of the TerraView and TerraLib version
    3.2.0

12
Extent of participation Recommendations for
additional participants
  • Who could contribute to this task?
  • ITC
  • Very many others...
  • Other issues
  • Coordination points with other GEO work plan
    tasks need to be improved
  • Potential risks that may impede completion of
    task inventory restricted to few aspects of EO
  • Gaps that have been identified that need to be
    addressed independently bring other dimensions
    of OSS
  • Potential Contributions to the CB portal /GEO
    Portal Links of OS with description, education
    tools from OS community members
  • Expected products OSS made available with
    e-learning and training materials
  • Expected date of completion of task go along
    GEO and GEOSS
  • Expectations of task lead from CBC increase
    participation

13
Final remarks
  • Combining open source software with the technical
    workforce available in developing countries can
    enable technology transfer
  • TerraLib and TerraView have INPEs support for a
    long term maintenance policy
