As you knew a raster image could be represented using a ‘colour table’. These colour tables are generated from the colour ramps. In gvSIG Online we have a series of colour ramps but for customized cases that may be interesting to create a new one. There is no problem, gvSIG Online allows us to do it.
We show you how to do it through a video-tutorial. In this video we follow these steps:
- We have a geoportal with a raster image where we can apply a concrete symbology (colour table). Let’s imagine that any of the existing colour ramps is what we want to apply.
- We access to the dashboard and we see that in our gvSIG Online there are several symbol libraries that have a series of colour ramps.
- We add a new symbol library that has two new colour ramps. For each ramp it indicates the colours that configure it.
- Finally, we apply a colour table to our raster image, using the new available colour ramps.
As you can see, gvSIG Online is growing in functionalities day by day and it is becoming a reference when implementing Spatial Data Infrastructures.
