For me it is a function in 4NEC2. It is available in EZNec as well, but unfortunately only in the very expensive pro version. When I select Surface Wave it asks me for a distance measured in kilometers, and a height measured in meters. Like the standard gain plots, it has two different views, the top down view looks very close to the top down gain view, although changes to an antenna have different changes to the two top down plots. The horizontal view, however, looks very different. Another thing to note is it measures the strength of a signal in milli- micro- or nano- volts per meter instead of decibels.

I see very little posted surface wave data. There are some web pages out there that talk about it, although most of them just give general information. Everyone seems to recognize gain plots, but no one seems to have any idea surface wave plots exist...
