It looks like my street block is getting some new utility poles.
We worked with the data for these utility poles on my project at Southern California Edison. That utility company covers an enormous area, and the utility pole database had some 5 million records (for 5 million utility poles).
The fun starts when you also carry joint-use poles in the database. These are poles owned by one utility (say, it is owned by Seattle City Light, and carries overhead power cables), which then leases space on it to other utilities (say, to CenturyLink for hooking telephone coaxial cable onto).
