One of the common areas of GIS use is forestry. Focus on these use cases, we have made a new symbol library. And, as usual, it is available from the “Add-On Manager“.
Following the steps defined in the series of post “gvSIG 2.0: Create symbol libraries” we have created this new symbol library. Let’s see how we have made it, so that it serves as a new example for users to create their own libraries.
For point symbols (markers) we started from two different sources:
– First, the collection of symbols used by the NPS (U.S. National Park Service). An excellent collection of public domain symbols.
– On the other hand, we used the font Trees & Shrubs done by Jim Mossman, also available by public domain.
To add symbols NPS, we followed the instructions made in this post. To fmake easier the identification of symbols, we have used a mass renaming tool files, because gvSIG names each symbol with the name of the file (in that case we used pyRenamer). By Inkscape we generated different selection symbols (coloring by yellow each symbol and appending “_sel” to the file name).
From that point is all ready to use gvSIG symbols importer. We import the symbols to “Forestry / NPS”. Automatically gvSIG creates the new library with the set of point symbols imported.As indicated in this other post we generate different SVG files that represent a set of trees and shrubs. We use the symbol importer, storing them in Forestry/Trees & Shrubs.Besides point symbols, we wanted this library contains a set of lines and brush symbols commonly used in forest maps.
Now we only have to create the package as it was explained in this post.
This package is available from the Add-On Manager (by selecting the URL http://downloads.gvsig.org/download/gvsig-desktop/ and searching for “Types / symbols”) or directly downloading the package from here.
