TRANSCRIPT
6th GEO Capacity Building Committee Meeting
TASK REPORTCB-07 01eOpen Source Software
João [email protected]
rINPE - BRAZIL
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)
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
Why TerraLib and TerraView?
Technology has changed
Previous generation of GIS
Built on proprietary architectures
Interface+function+database = 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
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
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
TerraView GIS that allows the
construction, visualization and analysis of a TerraLib database
FOSS – LGPL
It can be customized by Plugins
TerraLib
A library to develop geographical applications
Open Source Policy – LGPL
Open Protocols
Use DBMS
Allows users to customize a solution
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
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
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
Extent of participationRecommendations 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
Final remarks
Combining open source software with the technical
workforce available in developing countries can enable
technology transfer
TerraLib and TerraView have INPE’s support for a long
term maintenance policy
