It would be useful to have a generalised WKB reader (and writer) on CPAN.
As I write this code, I shall bear in mind that a WKB decoder would be a useful addition to CPAN. However, WKB is much more extensive than the limited scope I am looking at so whatever I produce will be a limited version that will be useful to some people. Either to use as-is or to build upon.
The first requirement I have from this USRN data is to find the nearest USRN to a given point. For that, the centre of the envelope is sufficient. In future, I will be wanting to plot the LineStrings so proper decoding will be needed but that's for another day.
