    Comparing version 15:51, 22 Apr 2010 by matt with version 16:00, 22 Apr 2010 by matt.

    The authoritative Canadian NHN homepage is on geobase.ca

    As of spring 2010 it is distributed in shape, kml, gml, and file geodatabase formats. Direct download address is ftp://ftp2.cits.rncan.gc.ca/pub/geobase/official/nhn_rhn/, which is throttled to a maximum of 2 connections per ip address. Http to same is not throttled, however date stamps are not retained then (and it's a little harder to bulk download).

    Attached is a Filezilla download queue for zones 08,09&10 (BC, Yukon, western NWT) in file geodatabase which adds up to about 12gb or so.
