After the generic background presented before is time to focus in the project itself The Current document is basically divided into two main parts or better said one part that includes the other one In this case would be the tutorial that includes a case study For this reason will separate the present chapter into two numerals the first one will explain some projects and gvSIG tutorials related with herein and the second one will describe the current situation about Catalonia region in terms of firefighting bases and software usage which is the deep part of the case study 4 2 Projects and gvSIG Tutorials After the creation of gvSIG in 2004 the program has been used for different kind of purposes The idea of free software makes teaching crucial for passing the knowledge from hand to hand The best way to transmit the know how is through tutorials because they give the general bases step by step so the user can compare in every single moment his results with the ones given by the guide Additionally at the end of it he can pass the knowledge to other users which in general terms is the aim of the free software politics 4 2 1 gvSIG Course 1 11 In the official gvSIG website there is a tab called user documents in which you can find all the type of projects in which they are involved you will find courses made under gvSIG direction educational material provided by the community 6 different languages and developers cou
