[Talk-ca] Setting up RoadMatcher and creating shapefiles

[Sam Vekemans]

Yup, its slighty more complicated. so with the effort to make the .osm
files available, roadmatcher 'aught' to be run.

My own ignorance for not wanting to learn, is just bugging others. So
should really stop that :-)

On the wiki 'geobase import' steveS did a great job of explaining it
and the steps to take, and others could probably help further.

The steps to 'omit roadmatcher, and omit downloading the current osm
area' is not yet listed. But im sure it can be worked out.

Btw, 'slicing the gml file' is only done because the resulting .osm
files are over 50 megs (no bigger than the greater-victoria.osm) is
fine to work with. the sq km size doesnt matter. (since its manual
copying), and using the NTS boxes as guides is only needed so we dont
trip over eachother.
