At this new post of the “Thematic maps” series we will see how to generate a package for sharing a thematic map with other users.
In the previous post we had generated our first thematic map, that will have been saved by default in home/usuario/gvSIG/plugins/org.gvsig.educa.thematicmap.app.viewer/thematicMaps.
At this way, in any gvSIG project we can see a “Thematic map” that has been created already. We only have to press “New” on the “Thematic Map” document from the “Project Manager”. This will open a window with a list of all the thematic maps available. It will allow us to access to the thematic maps from any gvSIG project, but not for sharing the thematic maps wirh other users. To share the thematic map we will have to generate a package.
Firstly we must know that when a thematic map package is generated we are going to get an install file from the add-ons manager of any gvSIG 2.0. What does this package contain? It contains the cartography (the files), the legends, the labelling, the maximum and minimum scale of viewing of each layer, the background colour…, it contains the complete thematic map ready to be shared.
The process is as easy as selecting the option in the corresponding menu: Thematic Map/Generate package.
A window will be opened, where we will have to indicate the folder where the package will be saved (the name will be created automatically). In our case, it has generated a package called ThematicMap-World_Countries-1-BN1.gvspkg.
Ready to be sent.
If you want to test it, this package and some other ones are available at the outreach website, in a section the objective of which is to be a catalogue with maps that are interesting for the users of this gvSIG extension and gvSIG Educa: http://outreach.gvsig.org/maps
By the way, if you want to contribute to feed this section, you only have to follow these instructions: http://outreach.gvsig.org/contribute
If you are the recipient of a Thematic map package and you are interested in the inverse process, converting the Thematic Map in a View (for changing its legend, edit it…) you only have to select the menu option: Thematic Map/Export to View
It will ask us for a file where the files will be saved (important: it must be empty), and it automatically will create the view equivalent to that thematic map.
That’s all for today… At the next post of this series we will see how to generate a package from a group of packages, that means, how to share groups of thematic maps in an only file.
