This unfortunately falls short. I find that you need to check the FCode across at least 3 different parts of the country to be sure. I've found there are regional variations in how FCodes are used. I hope to get back to my code in the next week. With the redaction it hasn't been a high priority. Also, no one has proposed a NHD import lately. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
