This is true regardless of the schema changes. NHD has a 3 year planned update cycle. Depending on the region, this means that the data may have been updated or not, but if you're working country-wide you have to be able to process the latest. The schema changes just an additional reason to not use the old data. NHD has a set of files in the older schema on their website but I don't believe these are being updated. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
