The National Hydrography Dataset (NHD) is a United States-wide w:en:hydrography dataset produced by the United States Geological Survey (USGS). This dataset includes lakes, ponds, rivers, streams, and other features related to water such as dams. As a product of the US Government, the dataset is in the public domain. Due to this and the general high quality of the data, some regard it as suitable for import into OpenStreetMap, and some of those people have proceeded with importing. This page details the process, progress, and mapping as the dataset is imported.

A description of the dataset can be found here on the NHD website.

Import Process

Warning
 Imports and automated edits should only be carried out by those with experience and understanding of the way the OpenStreetMap community creates maps, and only with careful planning and consultation with the local community.
See Import/Guidelines and Automated Edits code of conduct for more information. Imports/automated edits which do not follow these guidelines might be reverted!
Information
 Note: There is an effort (as of June 2011) organized by Ben Supnik, a X-Plane developer, to pre-process all NHD data to enable contributors to more easily merge this data into the OSM database. Read more about it in these mailing list conversations: NHD data extract (2011/04/26), NHD data import question (2011/04/27), NHD import and conversion - sample data (2011/04/28).

Please try to limit duplicate nodes/ways in your uploads. One solution is to alter scripts so that they make one file per feature class (by making large numbers of points per file) (waterbody, area, etc.) per subbasin. Merge these files in Josm and then remove duplicate nodes. This also provides an opportunity to check whether any features have been previously uploaded. Large files, which take along time to merge in JOSM, can also be merged together with Osmosis. Once you have the merged file, you can upload from JOSM as it will automatically split these large files into appropriately sized changesets.

Get the data

Geo Extract Options

Obtain High Resolution Shapefiles from the NHD web site by using the NHD Geodatabase Viewer or go to the NHD Geodatabase, which has a simpler interface. Read the "How to extract" instruction on the left, pop-ups must be enabled for the site.

Note: Some NHD items will appear in multiple adjacent sub-basin extracts. If possible, either load in an editor and preview for river bodies extending outside the map line, or test for duplicate NHD:ComID values in separate uploads.

NHD SubRegions can be downloaded directly from the nhdftp site

The NHD files are no longer shapefiles but are Personal GDB or File GDB files. These files can be difficult to process with open source tools but QuantumGIS and gdal have support for Personal GDB files with the default windows builds.

Python

Python scripts for converting the shape files can be found at https://svn.openstreetmap.org/applications/utils/import/nhd2osm/

  • I've had difficulty getting the NHD Area one to run, when ignored features are present. It looks like a comparison should be changed from 
    if l.GetNextFeature() == None:
    to 
    if l.GetNextFeature() is None:

Java

Here is a sample rules file to use with the Java Shp-to-osm.jar script based on the defined. NHD Rules

Projection

Default projection is 4269: NAD83

Attribute to tag mapping

Contained below are some possible mapping schemes, that is what OSM tags to assign to an object based on the attributes of the object in the original Shapefile. Note that there is no one unified scheme, and it can differ from one area to the next.

None of the three mappings listed here is up to date with the latest NHD files. If you wish to propose an import you may need to produce your own.

Mapping 1: Mapping

This may be the oldest mapping, and should be deprecated?

All Geometry
SHP Key OSM Tag(s) Description
ComID nhd-shp:com_id Common ID. Unique to all of NHD data.
FDate nhd-shp:fdate Capture date.
ReachCode nhd-shp:reach_code Reach (section) code.
GNIS_ID gnis:id=* USGS Geographic Names Information System feature identifier.
GNIS_NAME name=* USGS Geographic Names Information System name.
Elevation ele=* Feature elevation. Not used very often.

The NHD data comes in shapefiles, but most information is built into the single "FCode" field. The following describes a possible mapping.


Flowline (NHDFlowline.shp, LineString)
FType FCode OSM Tag(s) Description
ArtificialPath 55800 name=*, waterway=river Artificial paths are usually used to indicate the centerlines for rivers that are wide enough to designate with an multipolygon.
CanalDitch 33600 waterway=ditch; some may need to be hand-edited to waterway=canal A canal or ditch (usually with a concrete or earthen surround).
Connector 33400 waterway=stream "A known, but nonspecific connection between two nonadjacent network segments" [1]
StreamRiver 46003 waterway=stream intermittent=yes Intermittent streams.
StreamRiver 46006 waterway=stream Permanent/perennial streams or rivers.


Areas (NHDArea.shp, MultiPolygon)
FType FCode OSM Tag(s) Description
StreamRiver 46006 waterway=riverbank The polygon riverbank for a river that should be drawn wider than a line. This polygon will surround a line of code 55800 with the river's name.


Water Bodies (NHDWaterbody.shp, MultiPolygon)
FType FCode OSM Tag(s) Description
BayInlet 31200 natural=bay, might need to be natural=coastline Bay or inlet.
LakePond 39001 natural=water, occurrence:intermittent?? Intermittently visible lake/pond.
LakePond 39004 natural=water More permanently visible lake/pond.
Reservoir 43612 man_made=wastewater_plant Sewage treatment pond.
SwampMarsh 46600 natural=wetland A generic swamp/marsh area.
