Hi folks,
I have been working on making my own maps for around my area in eastern Washington. After looking through the tutorial (I have made some maps before, but the tutorial lays stuff out pretty well), I realized that there hasn't been a good way to download and organize the high-resolution water data from the NHD. I was clicking through the incredibly slow NHD viewer to download some subregions when I realized that they use a system that's nearly the same as the Seamless server for submitting requests, only the NHD emails you instead of making you wait with a browser window open. I then found a list of every subregion in the US (http://water.usgs.gov/GIS/huc_rdb.html) and threw them all together into a spreadsheet like we have for the DEMs. I'm hoping that someone else can find some use out it. I've attached the spreadsheet, which should be pretty self-explanatory.
The format goes like this:
http://nhdgeo.usgs.gov/jspapps/jsp/nhdQueue/[email protected]&REQUEST_TYPE=1&DISTRIBUTION_TYPE=5&Ref_Polygon_Ids=SubRegionNumber,%20&Ref_Layer_Connection_Id=1&FLOWLINE_COUNT=1&EXTRACT_RESOLUTION=2&INCLUDE_FLOW=F&TEMPLATE_SUFFIX=83v106
Has anyone found a nice map of all the hydrological units? I've found a bunch of maps that just have the boundaries, and also shapefiles which have labels I can show of each subregion, but there just doesn't seem to be any nice PDF of the US with subregions labeled so I can look and see which numbers to download for a specific region. I'm pretty new to this GIS stuff and haven't figured out how to make myself a map of those things from shapefiles.
Anyway, let me know what you all think. I hope someone can find the spreadsheet useful.
