Actually there is, there are a few companies that will make you highly accurate maps, but they take time and cost lots of money. Some cables that are in the ground are very very hard to track. -- Check out the new CLEC mailing list at http://www.robotics.net/clec

Sounds like there is a need for increased use of highly accurate positioning systems.
Tain't that easy. The SOP is to use the copper wire buried with the [fiber, sewer, etc] and excite it with 38 Khz; then sniff for it. But the LF signal can and does couple to OTHER conductors in the area, confusing everything. Often the only sure way is to hand dig down to what you think is there.... c a r e f u l l y.... -- A host is a host from coast to coast.................wb8foz@nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433

Would it be possible to use sonar to detect cables? Is this possible? Burying some sort of emitter at regular intervals? Does lit sheilded fiber give any sort of emmission that could at least hint that it's buried there? Just brainstorming anyway. -- batz Chief Reverse Engineer Superficial Intelligence Research Division Defective Technologies

Of course, this all assumes that the cables that are in the ground were propperly recoded in the first place.. (surveying errors when digging trenches to begin with may not ever be propperly corrected.) ---------------------------------------------------------------------- Wayne Bouchard Frontier GlobalCenter web@globalcenter.net Network Engineer (602) 416-6290 800-373-2499 x6290 FAX: (602) 416-6111 http://www.globalcenter.net ----------------------------------------------------------------------
