6th GEO Capacity Building Committee Meeting

TASK REPORTCB-07 01eOpen Source Software

João Soaresvianei@dsr.inpe.b

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
