Another of the (many) new features which can be found in the new gvSIG version is the library called “Military-APP6” with the symbol library being defined by the standard establishing the rules and requirements to develop and display joint military operational symbology within the Defense Sector. This is the biggest symbol library available in gvSIG and for sure, all the users not related to the defense sector will be surprised with the great number of symbols for military cartography, to represent any type of elements.
To create this symbol library, the document ”Commented APP-6A – Military symbols for land based systems. Defense Research and Development Canada – Valcartier. Techical Notel DRDC Valcartier TN 2005-222. “ has been used as reference.
To install it, as usual, we will use the “Add-ons manager”.
In order to make easier the search of symbols, a classification in 4 groups has been made: equipment & weapons; operations other than war; units; size units. Also, the two first groups have been divided in new subgroups.
Each symbol related to the units, it can be multiply according to the unity size. The units are represented by small top marks in each symbol. So, each unit symbol should be replicated a dozen times to represent all the possible unit sizes….that is something that can make harder to use it, because the need to browse between hundreds of “similar” symbols.
To overcome this military symbology difficulty, the folder “Size Units” has been created. gvSIG 2.1 allows at any moment, to join 2 or more symbols to represent one new symbol. This way, the user who needs it, can use a combined symbol created from “Units” and other from “Size Units”. The new symbol can be used and saved as combined symbol.
