[Gvsig_english] SEXTANTE Visibility Tool

[Angus Jeffery]

Hello
This Sextante Visibility tool is great. However, does anybody know if
it is possible to show the visibility of more than one point, for
example an array of wind turbines? Is it possible to do this by
referring to a .shp or .dxf which contains point data and contains
height attributes, etc.? Does anybody know if the tool takes into
account, or if it is possible to take into account earth curvature -
this is unlikely to be significant at close range, but could be at
10km plus.
Regards
Angus
