Today, I had a meeting with two people to go over what I have been working on soils data. It has a lot of cleaning up. When we were discussing, this person was talking about the edits with the NHD for every two years. What I would like to get more information about it on how every two years that NHD works or needs to make edits. NHD is a National Hydrography Dataset that is done by the USGS. Does anyone out there know what I was talking about ? Could anyone out there can directed me to where can I find ?
That will help to what I am looking for about it.
