Hi Mike!
I have resolved the problem of the visualization of the skirt, using
osgTerrain::Locator, osgTerrain::NoDataValue, and drawing with
osgTerrain::GeometryTechnique instead of drawing the HeightFieldLayer
with ShapeDrawable.
I am using Locator however I don't want my terrain to be drawn using the
locator->setCoordinateSystemType(osgTerrain::Locator::GEOCENTRIC)
I have tried to apply "GEOGRAPHIC" but it doesn't visualize anything.
I would perhaps need a Cartesian Locator for the correct visualization
of my terrain.
Thanks in advance
Aurora

The existence of the skirt is controlled by your NODATA value. You must
set the NODATA value appropriate for your dataset:
hfLayer->setValidDataOperator(new osgTerrain::NoDataValue(
YOUR_NODATA_VALUE ));
Here are various links to review concerning the concept of NODATA:

I need to get the terrain as in the figure that I send you, but
without
visualizing the skirt.
