I don't know. My wife is from there, but her accent is all her own.
I note that Albany, Syracuse, Rochester and Buffalo all appear as green dots, connected by a green line, wondering if the line is the median of I-90, though that seems too ridiculous for words. And the new growth along I-85 corridor through NC, which is becomeing way too crowded, shows up rather well.
It's probably not the median -- many of the interstates are discernible as dotted green lines, because small communities have probably grown up next to the interstate between larger cities. The alteration of ground cover in even a small area can be quantified, it appears.
There are a couple of places in Virginia with almost continous green lines along the interstate that might be the median strip, I-81 that parallels the VA/WestVA border and I-95 south of Richmond. Regarding the latter, I was on it relatively recently, and it still is a 2-lane interstate in both directions with a relatively wide median. So this analysis may be picking up grass in wide interstate medians.
