Hi,
New to mapping, so please don’t assume I know anything.
I think I can get a database of Australia’s Highway 1, but not sure about any of the details.
What I’m hoping to achieve, is to calculate latitude and longitude for a position, which lies x km along the highway, from a starting position.
Anyone care to offer even ball park suggestions, as to how that might be achieved?
I’m hoping to achieve this within a php program, or perhaps to derive a database of coordinates, that lie at various distances along the one path.
Any clues gratefully received.
Zip.
