I need to convert location coordinates from Latitude/Longitude to V&H (Vertical/Horizontal) and back again. For those who've never come across it, V&H is a coordinate system developed by and used heavily in the Telco industry. It's used to calculate mileage for circuits via the formula

sqrt((V1-V2)^2+(H1-H2)^2/10)

[download]

I can use Geo::Coordinates::VandH to convert V&H to Lat/Lon but I've struck out on a package or algorithm to convert Lat/Lon to V&H. I've found simple calculator programs to convert one coordinate pair at a time but I have to convert potentially tens of thousands of coordinate pairs as a cross check on existing records. Doing this one pair at a time isn't an option. Is anyone aware of a solution for this?

Thanks,

Jack
