[postgis-users] Line of sight (LOS) Calculation

[Ofer Zilberstein]

Hi,

I would like to calculate LOS (visibility)  from a point to an area fast as
possible.
For example looking from one observation point to 1000 targets that
represents the area
The option is to use terrain existing tools such as ARC Toolbox or using
function in POSTGIS
I wander if there is an experience with such task and what will be the
execution time for a single query

Thanks...
