2 What are we going to see? The project: Structure and Main Characteristics gvsig, Standards and Interoperability Use of Standards on gvsig Non Standards on gvsig Conclusion

3 Project background: gvsig Conselleria de Infraestructuras y Transporte (CIT) or Dept of Infrastructures and Transport, is the maximum authority in the Generalitat Valenciana (government of the Valencian Community) for Public Works, Transport, Architecture, Ports and Coasts, and Energy. Migration project to free software solutions (2004/2008). An advanced GIS Client was missing: Let's invent it. A fast evolution: Conselleria, Generalitat --> National and international.

4 Structure and main characteristics Development language: Java (Multiplatform). Adheres to the guidelines of the European Union Inspire. Free license (GNU/GPL). Modular, scalable, powerful. Simple interface: user friendly. International (spanish, valencian, english, basque, gallego, french, italian, portuguese, german, czech, polish, romanian, mandarin...). R & D & I Project

5 Structure and main characteristics Complementing GIS SDI world (Not only a web site) Different interesting areas have been developed under a horizontal platform: Vectorial, raster, network, analysis, 3D, Mobile,... Global aim: Give solutions to all needs related to the geographic information management based on the integration of free technologies

6 Reprojections Geoprocessing Web Services (SDI) Symbology SEXTANTE WEB SERVICES PUBLISHING gvsig MOBILE 3D NETWORKS RASTER Structure and main characteristics Edition Spatial Database Topology Labelling

7 Project Dimension Mail Lists: more than user subscriptors Well known countries with registered users: +50 Well known countries where gvsig has been download: +60 Interface translated more than 15 languages Documentation in five languages. 75 sharing their work translating

8 GvSIG, standards and Interoperability Standards Open Source Interoperability

9 GvSIG, standards and Interoperability Standards Standards: the unique way to have Interoperability Standards + Interoperability = Share Information Problem: A Standard doesn't guarantee Interoperability. It would be necessary to have a reference implementation (like Java) Interoperability

10 GvSIG, standards and Interoperability Standards Open Source Open Source ensures compliance with standards Share Information - Share the knowledge

11 GvSIG, standards and Interoperability A Standard doesn't guarantee Interoperability; but open source ensures it. SDI 100% free to ensure the Interoperability Interoperability Open Source

12 GvSIG, standards and Interoperability Standards Open Source Interoperability

13 Use of Standars on gvsig

14 Use of Standars on gvsig Supported file formats: Reading Writing SHP GML GML ECW KML KML DXF PNG JPEG2000 GeoTIFF JPEG2000 SHP DGN (v7) ECW TIFF DXF MrSID GeoTIFF DWG MrSID

15 Use of Standars on gvsig GvSIG can read vector and raster files standard files. GvSIG can write files that can be opened by other software.

16 Use of Standards on gvsig KML files is good example. Good example of interoperate between gvsig and other software like Google Earth. Standards allows share data with gvsig mobile version.

17 Use of Standars on gvsig

18 Use of Standars on gvsig. WMS Web Map Service. It allows publish geographic raster data in a standard way. This service is a good way to share geographic information and be understood by lots of applications like gvsig.

19 Use of Standars on gvsig. WFS Web Feature Service allows publish vector data on internet in a standard format. (GML) This vector maps includes associated data for each features.

20 Use of Standars on gvsig. WCS Web Coverage Service it's is less used but allows shared coverages. These published layers includes data like multi band images.

21 Use of Standars on gvsig. Services Other Web Services as Catalog allow search Geodata on the net in an simple and standard way. CSW Web Feature Service Gazetteer is available too. The easier way to find by name in layers.

22 Use of Standars on gvsig. Spatial Database Allows access to Postgis, Oracle, ArcSDE and MySQL Is difficult access with closed formats. For instance arcsde library is slower on external software than on ARCGIS

23 Non Standars on gvsig. Files supported: DWG (only to 2002 version are opened), DGN Web Services supported: ArcIMS. Spatial Databases: ArcSDE, Oracle Spatial.

24 Conclusion Standards + Interoperability + Open Source = Spatial Data Infraestructure 100% free UE should demand open standards Standards Share Information

25 Conclusion Standards + Interoperability + Open Source = Spatial Data Infraestructure 100% free UE should demand open standards Standards Share Information Share the knowledge Open Source

26 Conclusion Standards + Interoperability + Open Source = Spatial Data Infraestructure 100% free UE should demand open standards Standards Share Information Share the knowledge Open Source Interoperability Share

27 Moving Forward Together
