The copyright is gone from topographic database but the road centre line
database (like DCDB) is an entirely different kettle of fish especially over price.
There are several suppliers of Road Centre Line databases in NZ, with Critchlow
and Associated, Aerial Mapping and Terralink being the ones I know about. And
yes, they are expensive - building and maintaining accuracy to level required
for emergency services is not cheap to do and the price reflects this.
