Problem in getting Sky view factor value



I am calculating the Sky view factor for my project and I am using the definition created by Chris which was uploaded on the forum. Would like to know where I am going wrong; why I am unable to get the svf for a point located on my model.

Also, do we also need to provide a wether file for this analysis? I mean on what basis it is calculating the SVF.

Hello everyone

In addition to my previous question - I have found sky view analysis example on Hydra share; could anyone tell me is it same as Sky view factor? Does it also give the result in SVF?

If not then what’s the difference in these two definitions? I mean the one which i have asked previously and the one which is attached in this.

Also, Why the legend colours are not matching with the colours in the street canyon.
