Well, let’s get into GvSIG…

TRANSLATION NOTES: Please read some comments at the end of this post.


I had been somewhat lazy (*), but there’s no option, it has appeared a non smokers group who want a GvSIG course so I have a week to learn how to use it and start the tutorial that will take me 2 weeks of my evening hours. Also with this post I start a new category on my sidebar: GvSIG.

Really they don’t asked that application, they asked for a free one and also easy to use… free many, easy to use questionable! …exciting without doubt! I think I will take the opportunity to compare it with Manifold and others.

If they had $250, I would recommend Manifold to them because I know what it does and what doesn’t, but as they don’t want to spend money then, it is better going for a tool that has ready manuals and that is stable (although it won’t be free for them the learning curve… not mine also).

And for those who have no idea which is GvSIG, here the basics:

· Arises (as an offer to tender) in late 2003, was developed by IVER who won the game, but has the institutional umbrella of the European Fund of Regional Development (ERDF), the Ministry of infrastructure of Valencia and the Jaume I University

· The license is GNU GPL

  • It is built 100% on Java (with the exception of some proprietary libraries of ECWy MrSID), so it runs on Windows, Linux and Mac.
  • Libraries in what has been developed are standards like Geotools and Java Topology Suite known as JTS, among others.
  • It is interesting that apparently supports “internationalization”…
  • it’s supposed that adapts natively into user’s language… mmmm?
  • Supports commonly used files as shp, dxf, dwg, dgn, kml and even gml
  • Supports raster formats like MrSID, GeoTIFF, ECW and ENVI
  • Supports OGC standards including WMS, WFS, WCS and nomenclatures services
  • Promotes the five characteristics which were offer time requirements: Portable (Windows / Linux at that time), Modular code open, no-cost licensing, Interoperable (at least with AutoCAD, Microstation and ArcView at that time), subject to standards.

If you want to extend, it can be integrated IMS services and other wonders through extensions which include viewing and editing OpenStreetMap mapping, connection to ESRI extensions as ArcIMS and ArcSDE… among others.

The most enriching of this tool is the community behind its development; dissemination and documentation… something that guarantees a certain level of sustainability that do not have all open platforms… at least with much emphasis in Spanish.

There I tell you how it goes.


(*) hacerse el currito: When your not working but just viewing how time passes then you’re somewhat lazy.
