The few poles that have been mapped in my area (rural farming countryside) are the large cross-country grid feeders (generally 100Kv and up) and a few 9.6 Kv distribution lines. Having said that, it is my impression that 80%-90% of the telephony circuits are buried cables with cable tap boxes every 1/4-1/2 mile. The telco does use existing power poles for drop lines (from a cable tap to a residence) and occasionally strings overhead cables.
Power poles (around here) have 4 designated (but invisible to the casual onlooker) segments: The electrified segment at the top, a guard section (in which no wires are connected), a telecommunications section, and a minimum ground clearance segment. The exact measurement/height of each segment varies based on the height of the pole and other factors. Without trying to off topic, something which is attendance with a few power poles is a telecommunications 'Remote Terminal' cluster. This is usually 2-4 vertical cabinets, one is a wire cabinet, and the others contain active electronics to support telephony/data circuits in a location far from the central office. In my case, the nearest such RT is 1 mile up the road, and 6 miles from the central office. It might be nice to map the locations of the (obviously present) RT boxes.
