1 gvSIG: Open Source for handling Geospatial InformationMario Carrera Rodríguez

2 Generalitat Valenciana (GV) is the government of the Valencian Community (Castellón, Valencia, Alicante) Conselleria de Infraestructuras y Transporte (CIT) or Regional Government of Infrastructures and Transport, is the maximum authority in the Generalitat Valenciana for Public Works, Transport, Architecture, Ports and Coasts, and Energy.

3 Management of files, etc.Project Origin The administrations need computer applications to develop their functions Office automation Databases Signing registration Management of files, etc. · La informática se ha convertido en una pieza clave e imprescindible para el desarrollo correcto y competitivo de cualquier trabajo. · Desde la redacción de un documento hasta la gestión de una emergencia son tareas en las que nos asisten hoy en día aplicaciones informáticas, facilitando el trabajo pero, sobre todo, proporcionándole una mayor calidad final. · La administración pública tiene la obligación de relizar su gestión de manera eficaz por lo que necesita las mejores herramientas informáticas del mercado...

4 There are two options to obtain computer applications:Project Origin There are two options to obtain computer applications: Proprietary Software Open Source Software · La mayoría de las aplicaciones profesionales existentes en el mercado siguen el modelo de software propietario caracterizado porque no se tiene acceso al código fuente. · A raíz de la política abusiva de actualizaciones y mantenimiento que adoptan las principales firmas de software propietario, la CIT se plantea la migración a software libre de todas sus aplicaciones informáticas. · Vamos a ver a continuación cuáles son las razones por las que la CIT apuesta por el sw libre.

5 Annual maintenance Version updatesProject Origin Proprietary Software (I) High cost of license and maintenance. Tendency to skimp on installations. Promotion of illegal software. License · En primer lugar el coste de una licencia (puesto de trabajo) de una aplicación propietaria suele ser considerablemente elevado. · Esto provoca que exista una tendencia a escatimar en licencias y por consiguiente se usa en un nº muy limitado de puestos de trabajo. · Además se fomenta el uso de software pirata para cubrir los demás puestos de trabajo. Annual maintenance Version updates

6 Technological dependence of the provider.Project Origin Proprietary Software (II) Technological dependence of the provider. The provider choose the new functionalities and when they will be available. · Otro inconveniente es que se genera una dependencia ya que el cliente no es el propietario de la tecnología (el código fuente). · Además el que marca cuáles son las funcionalidades y cuándo se entregan éstas es siempre el proveedor.

7 Bad use/quality relationship.Project Origin Proprietary Software (III) Bad use/quality relationship. You pay for the product. Bad use of the INVESTMENT. · Se produce, al fin y al cabo, un mal aprovechamiento de la inversión. · Pagas mucho por complejas aplicaciones de las que se utiliza un pequeño porcentaje de su potencial. · Pagas por un producto que a medio plazo queda obsoleto. · Realmente no estaríamos hablando de una inversión en el sentido económico de la palabra.

8 There isn't a cost for the license. Project Origin Open Source Software (I) There isn't a cost for the license. Installation in an unlimited number of computers. · En el caso del software libre directamente el coste de licencias (puestos de trabajo) es nulo. · Podemos cubrir todos aquellos puestos de trabajo que necesitemos sin sobrecoste.

9 Freedom to give solutions to our problemsProject Origin Open Source Software (II) Technological independence Freedom to give solutions to our problems Capacity to develop new functionalities · Somos propietarios de la tecnología (el código fuente) con lo que poseemos total libertad para dar solución a nuestros problemas, encargando la implementación de nuevas funcionalidades a quien mejor consideremos.

10 Implemented functionalities = required functionalitiesProject Origin Open Source Software (III) Implemented functionalities = required functionalities You pay for service Total use of the INVESTMENT · La relación uso/gasto es óptima ya que las funcionalidades implementadas coinciden con las demandadas, es decir, pagas por lo que usas. · El gasto económico es realmente una inversión ya que pagas un servicio, no un producto.

11 To run the program, for any purpose.Project Origin Open Source Software: The “freedoms” Four freedoms of the Open Source Software: To run the program, for any purpose. To study how the program has been built, and adapt it to your needs (access to the source code is a precondition for this). To redistribute copies so you can help your neighbor. To improve the program, and release your improvements (and modified versions in general) to the public. Para saber si un proyecto es Software libre, es sencillo, tiene que cumplir estas 4 libertades. Escribir las 4 libertades. Objective: Maximize the rights of the client (who has the product).

12 Project Origin Open Source Software: The licenses Software license = Legal instrument that governs the usage or redistribution of copyright protected software. It differentiates the Open Source Software from the other kinds of software. GNU/GPL License: It guarantees that the improvements and redistributions will be always “free”.

13 Technological independence. Optimization of the investment. Project Origin Why Open Source Software Why Open Source Software? Technological independence. Optimization of the investment. Quality industrial structure. Son varios los factores que al menos nos han hecho apostar por el Software libre, entre ellos podemos destacar la Independencia Tecnológica, la Optimización de la Inversión y favorecer el desarrollo de Tejido propio industrial y de calidad.

14 Technological independence Sustainable developmentProject Origin gvPontis: migration of IT to free software solutions Conselleria de Infraestructuras y Transporte Migration to information systems under LINUX (end of 2002) Areas of action: Office Suites Operating systems and communications databases Corporate systems within Conselleria GIS y CAD Development of GIS client: gvSIG Optimization of the I.

42 Spatial Data InfrastructuresActual situation Old model (corporate GIS) A lot of map servers. Every server is optimized for “its users” using its software... at the expense of possible users with another software, another brand of GIS, another formats of data. Creation of multiuser GIS information islands.

43 Spatial Data Infrastructures

44 Spatial Data InfrastructuresNew model Spatial Data Infrastructures (distributed GIS): Objective: Making easy the access to the G. I. The system is the network (internet/intranet). Communication through standars (web services). Extended client-server model. Decentralized network of servers. Evolution: Desktop GIS client -> Desktop GIS – SDI client

45 Spatial Data InfrastructuresSDI projects GSDI: Global Spatial Data Infrastructure. Promote the international collaboration to create SDI Antecedents: Clinton Order (EEUU, 1994) Building of a National Spatial Data Infrastructures (NSDI) European Union: INSPIRE (2004) INfrastructure for SPatial InfoRmation in Europe. Laws to guide the creation of SDI for every country.

Metadata search and retrieval for data and services Middleware Geo-processing and catalog Services Direct data access Catalogs Metadata update Other data e.g., administrative, statistical, env. reporting Content Repositories Servers Hoy en día hablar de información geoespacial es hablar de integración de tecnologías, así lo vemos en la arquitectura del proyecto (futura directiva europea) INSPIRE para la construcción de la Infraestructura de Datos Espacial (IDE) europea. Servidores de mapas y de catálogo, Bases de datos Geoespaciales, clientes ligeros y pesados son distintas tecnologías que se deben entender para implementar una IDE, podríamos estar hablando igualmente de SIG distribuido. Coverages Features Distributed Geographic reference data

47 Metadata: datas that describe another datas. SDI components Data: reference system, transport network, pollution, vegetation, traffic, etc. Metadata: datas that describe another datas. Services: offer a group of funcionalities that are useful and interesting for a community of users.

48 Web Feature Service (WFS) Web Coverage Service (WCS) SDI services Services The user isn't interested on the download of the data, but obtaining the needed answers directly, that are offered by a service. The SDI services offer functionalities accessible on-line through a simple navigator or browser: Web Map Service (WMS) Web Feature Service (WFS) Web Coverage Service (WCS) Nomenclator Service (Gazetteer) Catalog Service (CSW)
