public class NODFile
- extends ImgFile
The NOD file that contains routing information.
NOD1 contains several groups of routing nodes.
NOD2 contains road data with links into NOD1.
NOD1 contains links back to NET (and NET contains links to NOD2). So there
is a loop and we have to write one section first, retaining the offsets
and then go back and fill in offsets that were found later.
I'm choosing to this with Table A, as the records are fixed size and so
we can write them blank the first time and then go back and fix them
up, once the NET offsets are known.
So we are writing NOD first before NET and NOD1 before NOD2. Once NET is
written then go back to Table A and fix the label offsets in RGN.
