Hi all,
I'm undertaking some visibility analysis in Arc/Info and I would like to incorporate a variable into the calculation that will take into account the maximum distance that a person will be able to see from a given viewpoint. For example the human vision might not be able to see further than 3 miles for example, if though the algorthm will take account of distance further away than this is topography allows.
I've consulted all the help files, but I was just wondering whether anybody new of a way of incorporating such a parameter into the original calculation in a similar way to setting the height of the viewpoint from the ground for example.
Many thanks, Will
