I need one of those pen contraptions that you roll over blueprints and
aerial photos that then give a numerical value to the distance traveled.
What are they called, and what's a good supplier of them?

Basically put, it's a map/blueprint measuring wheel just like this

I believe you're thinking of a "planimeter".

The OP is looking for a "wheeled scale", not a planimeter.

A planimeter is for "measuring" (actually, mechanically summing) the
area enclosed by a perimeter.

btw... if anyone needs one, I'd be willing to loan mine out. I
bought one on ebay several years ago, I actually needed one.

I googled wheeled scale and didn't see anything that looks like what I need.
The planimeter looks like it. What I envisioned is a pen shaped device with
a small roller wheel at the tip that one would trace every line they wanted
to measure on a plan. I would use it on arial photographs to measure
sidewalk lengths on irregular sidewalks within HOAs. Not the straight
sidewalks, but those that snake all over the place. I currently use Google
Earth Tools Ruler Path, but sometimes I have lots of little lines, and no
long paths.

$60 is a little spendy, but I may spring for one, or try to catch a used one
somewhere.

That's a new word on it for me, but it looks like it is the most
accurate. Thanks for posting it.

That's the one.

I had the "meter" part correct, but had forgotten the first part of the
word. The images from my Google search led me to believe that "planimeter"
was the full word.

The box for my K&E is labeled "MAP MEASURE, D1741". On the
back of the measure itself is impressed, "Hamilton Watch
Company". I bought it new, sometime around 1940, and paid
$4.50 for it. It has inch and cm scales.
