Any one particular cable might not move often, but if a telco owns N bucket trucks it's a safe bet that about N cables move every workday.

Telcos are notoriously secretive about the location of their fiber. They even got most state legislatures to exempt it from state-level FOIA laws.

If you have a map of all utility poles you could probably just avoid every straight line between any of them within some reasonable distance of eachother.

Most "utility pole maps" only show poles with power lines on them.

A ton of telco cables are on telco-only poles (basically just a really straight tree trunk shoved in the ground, no cross-arms at all).

OpenPoleMap is achievable. Just don't expect local governments to subsidise the mapping of obstacles to drones of the likes of Amazon.

it's an approximation of dangerous areas, catenary curves are more accurate than straight lines but you don't know the length of the cable so you don't know the droop height.
