Re: MI v AND h COORDINATES
It's ATT's coordinate sysstem for billing LD calls. So you must either have switch locations or rate centers. Cartographic coordinate systems are not something I'm strong on, but basically it is a conversion so that you can use the Pythagorean Theorem to easily calculate distance between two points. It's good for Continental US and Southern Canada. But for Alaska, Hawaii, and I suspect N. Canada, the conversion is inaccurate. By no means is the accuracy of any location at the street level. I had planned (am planning?) on writing a MapBasic program to convert V H to Lat Long, so I have a bit of code I found on the web w.r.t. the conversion. Be happy to pass it along, but an easier solution is available. Telcordia (aka BellCore) sells a small app that converts it to Lat and Long.

RE: MI v AND h COORDINATES
Is there a way to place the conversion from Lat Long to VH though. Our system uses this set up in locating. Do not like it that much, creates to much extra paper work for the field personnel.

RE: MI v AND h COORDINATES
Yeah, it goes both ways (I think the math is easier converting to V H rather than back). Check out Telcordia's web site for their program that does the conversion. Or if you're adventurous I can send you the code that I found on he web. T At 08:43 AM 8/2/99 -0400, Richard Takacs wrote: Is there a way to place the conversion from Lat Long to VH though.
