  57. 57. gaSIG is easy to learn, yet versatile andefficient enough for demanding GIStasks.we believe that gvSIG has matured into apowerful application that can be usedproductively in many workingenvironments, especially when used incombination with other open sourcesolutions such as GRASS GIS.19 Jan 11 GWF-2011
  58. 58. We have used the software in a numberof our own projects and made a numberof modifications to it that we feel couldalso benefit other users of gvSIG;including a restructuring of the programmenus, an easier installer that includeseverything needed in one package andintegrated GRASS GIS modules.19 Jan 11 GWF-2011

  67. 67. There are plenty of software in manyfields, including GIS, which can be usedto solve problems pertaining to respectivefields. If students are not exposingthemselves to OS, they are missing a bigopportunity to get excellent training.If any company is not using Opensource,then it is not taking a well informeddecision. Company is not getting value onhis return.19 Jan 11 GWF-2011
