Calculate degrees of visibility

Discussion created by dcn23 on Mar 18, 2013
Hi all,

I am creating a couple of scripts using python that calculate the visibility of surrounding greenspace features (parks, forests etc) from a number of observer points (houses). I have created one that calculates the total area of visible greenspace for every house, however now I want to create one that indicates how many degrees of green space is visible to each observer. For example a house within a forest would have 360 degrees of visibility while a house that can only see a section of park might only have ~30 degrees visibility.

I have access to arcGIS 10.1 and have been using the viewshed tool previously. I can also use all open source python like OGR etc.

Has anyone got any ideas on how to approach this? Let me know if it is not too clear one what I am trying to do...

thanks in advance,

Dan
