[Talk-ca] Cleaning up after the GeoBase import

[Richard Degelder]

Simon,

Combining the ways will defeat the possibilities of further use of the
GeoBase data for the area.  Unfortunately the GeoBase NID is unique for the
single segment only and combining multiple segments will make adding
additional data based on those unique NIDs, such as address data, impossible
as will further updates to the data in future GeoBase updates.

The only practical method to deal with the data is, as Richard Weait
suggested, to use relationships for the data that is common for the ways.
This is unlike the American model for the TIGER import but it also allows us
to modify and update the data much better based on future GeoBase updates
and to later incorporate additional data that we did not use in the intitial
GeoBase import.  Of course this does not prevent individual mappers from
adding aditional details or even new ways onto the map at the same time or
for correcting the map where there are errors or changes prior to a GeoBase
update being rolled out over an area.
