Viewsheds

[Francisco Estrada Belli]

Dear Friends

To all of you who have been doing viewshed analysis and to programmers at
large:
Has anyone seen a binary or source code for a cumulative viewshed program
called r.cva? It was mentioned in a recent "Journal of Archaeological
Science" (11/1998).
No response from the article's authors so far, so I wonder if someone else
has come across it and wouldn't mind sharing it with me.

Thank you,

Francisco
