I've been using the python scripts and uploading with the balrog scripts (http://www.openstreetmap.pl/balrog/bulkupload/) , they seem to work more reliably for me. To avoid collison with others' data, I have noted the presence of previously uploaded stream and waterbody data and gone back after import and deleting the usually less correct NHD data. This is actually not that big a deal as other users usually focus primarily on major rivers and large bodies of water. > I recommend maintaining just 1 version of the data for each script, with a > comparision chart (like i have with the Google Docs chart), as they both > need to have all the same tag-matches, and just keep track of the script > version. > > How are you keeping track of the National Dataset? > For Canada, Im thinking at using a GoogleDocs spreadsheet might be easier, > since there are so many different tiles (canada is made up of an NTS Grid > of only 4,984 unique tiles) where some will be uploaded at different levels > of completness... and different levels of data available.

In the case of NHD, I think most (all) are uploading the high resolution data, though these seem to not be available for all subbasins.
