The video of the fifteenth module is now available, in which we will see the main functionalities of the 3D extension in gvSIG, based on NASA WorldWind application.

In this module the user will learn how to create a 3D View from a 2D one. The 3D Views that we can create are flat views, when we work in local areas, and spherical views, when we want to see them on the terrestrial sphere.

In the 3D Views we can visualize the digital elevation models, and we can overlap any other layer on them, such as an orthophoto.

On the other hand, if we have a vector layer with building footprints, and a field in which we have the number of floors or the height of the building, we can apply extrusion, so that we can see the polygons vertically as if it were the building, and it helps us to visualize the structure of the city in an easy way.

Finally, another functionality available in the 3D module is the tool to create animations. It’s made by capturing screens in certain frames, and then a video is created, interpolating between the different frames automatically. It’s very useful for a presentation, when we want to show the different areas of our city in detail.

The cartography to follow this video can be downloaded from this link.
