I would like to create the building footprint (as polygons) from the raster (I obtained it from LAS files), but somehow mosaic tool doesn't work - I guess I do something wrong, could anyone suggest me another approach, or what I do wrong? I would really appreciate it.

I can see the shape of the buildings with different height but can't get the polygons out of it that will be as the rooftops shape.
