Sky View Factor analysis point by point

Hi everyone, is it possible to perform a SVF analysis point by point? Instead of running the analysis through a mesh? I’d like to obtain the values for the SVF on certain points, but still don’t know how is it possible. When assigning a list of small surfaces for the analysis, each surface has 0% of SVF.
SVF is an important factor when analysing UHI, so I’d like to obtain the values shown in the gradient (like on the image below) by a list of points (without using Sky Exposure) instead of surfaces, is that possible?

It is possible using the method you tried: small surfaces in such a way that the grid size is big enough to create only one point. I suppose this is what you tried, so maybe the surface normal needs to be flipped.

Now it worked! When fliping surface normals. Thanks once again Abraham!
