The function called Derived Geometries is now available in gvSIG 2.1. We can install, as usual, through the Addons Manager .
And how this new function works?
It creates layers of polygons or lines from a point layer , or polygons from polylines.
Let’s see, through a practical example, the operation of the tool Derived Geometries . The steps detailed in the video are :
- Load a point layer obtained by a GPS survey conducted on a set of buildings.
- Add the point layer as layer events, indicating what are fields containing X and Y coordinates
- Export the layer of events as points shapefile, then label it to better show the points belonging to each building.
- Run the tool Derived Geometries to generate a polygons layer representing the different buildings
