Introduction

From the layer menu, in properties, you can access the Symbology section. It is possible to change or configure a new symbol clicking on “Select symbol” where you will find different configuration options.

Click on the “Select symbol” button and then on the “Properties” button. The window which opens will allow you to edit the properties of the symbol. This is the same window that will open if you click on “New”.

By default gvSIG symbolises the layers with 'unique symbols'.

As well as the basic options that can been seen at first glance, such as colour, breadth and the type of units in which the symbol is to be represented, you can also edit the properties of the element. Next a classification of the properties of an element is made according to its geometry type.

The dialogue boxes that open have common sections and others that are specific to the type of geometry, we see them as follows:

When a symbol, is configured from its Properties, be it a point, a line or a polygon, it can be defined:

Under colour you find a scrolling bar, which allows you to play with the grade of the transparency of the elements. This way, you can superimpose polygon layers without interfering with its display.

We can also specify if they are units “on the map” (the size would depend on where the zoom is set) or “on paper” (it will have a set size, both on screen and when it is printed).

Specific characteristics of each type of geometry:

Symbol type:

Mercator Lines Fill-in
Of character Simple line Simple fill-in
Simple mercator Mercator lines Image fill-in
Mercator image Line image Mercators fill-in
Of character Simple line Line fill-ins
Of character Simple line Gradient fill-ins

The mercators represent the layers of the points.

The lines represent the linear layers.

The fill-ins represent the polygon layers.

All three together represent the multi-geometric layers.
