[OSM-talk] LINZ import

[Robin Paulson]

a number of OSM mappers in new zealand are currently working on the
import of Land Information New Zealand data into OSM

one of the issues that has come up is the question of what to do when
there is existing data. we've got a few ideas, but none of them are
optimal

does anyone who has experience (or not) of other imports have any
suggestions on how best to do this?

we're loathe to delete existing data, but all other options look a
hell of a lot of work

the import data set contains around 90 data types, including roads,
which probably pose the biggest problem

cheers
