The USGS produces and distributes the National Hydrography Dataset (NHD), Watershed Boundary Dataset (WBD), and NHDPlus High Resolution (NHDPlus HR) in Esri’s proprietary File Geodatabase (FGDB) and as a variety of spatial web services. NHD and WBD also are distributed in shapefile (SHP) format, however, NHDPlus HR is not distributed in shapefile format because the datasets would frequently exceed limitations on shapefile file sizes. The USGS has actively been exploring non-proprietary, open source formats for spatial data distribution to supplement and extend the FGDB and spatial web services deliveries. A variety of open source formats were recently evaluated as potential downloadable delivery formats, including GeoPackage, GDAL/OGR, GeoSPARQL, GML, GraphDB, SpatialLite, PostgreSQL+PostGIS, and various XML formats such as GeoJSON. After researching and testing these options, we found that Open Geospatial Consortium (OGC) GeoPackage is a suitable, modern, non-proprietary spatial dataset downloadable delivery format. GeoPackage is designed to be as lightweight as possible, and to be contained in a ‘ready-to-use’ single file. Since a GeoPackage is a true relational database (based on SQLite) with built-in indexing, it supports direct use, meaning that:

Geopackage is an open-standard product with active development by OGC and the user community. GeoPackages support both vector and raster data - including tiles and pyramids, as well as being designed for extensibility (i.e., R-Tree indexing extension for much improved performance when querying vector data, Tiled Gridded Elevation Data extension, Related Table extension, customisable extensions, etc.). Geopackage also supports z & m values. In addition, GeoPackage extensions may be developed to support additional types of geospatial data such as routing networks. Many proprietary (e.g. Esri) and open source (e.g. QGIS) desktop GIS software solutions support the use of Geopackage. A series of preliminary GeoPackage USGS dataset conversions for review are available at: ftp://rockyftp.cr.usgs.gov/ngtoc/hydro/outgoing/GeoPackage_hydrography_examples/ We welcome appraisals and suggestions - please send feedback to Greg Cocks ([email protected]).

Interested in Helping with NHDPlus High Resolution? Contact: Cynthia Ritmiller ([email protected])

There are two ways you can help with NHDPlus HR: 1. Improving the NHD or WBD prior to NHDPlus HR Production Partners proficient with NHD or WBD editing tools can perform the required review/quality control (QC) to fix problems in the NHD or WBD data before the datasets are used in NHDPlus HR production. Partners who have local knowledge but are not trained editors can get involved in the review/QC effort following the release of the web-based Markup Application. Please contact the USGS Partner Support Point of Contact in your area for questions about NHD or WBD editing. 2. NHDPlus HR Beta review/QC The USGS is seeking volunteers to perform a review/QC of the NHDPlus HR Beta in various Hydrologic Regions. This opportunity is ideal for users with previous NHDPlus Version 2 (medium resolution) experience and, most importantly, local hydrography knowledge. Once these changes have been reviewed and approved by the steward, they are incorporated into the NHD or WBD. Please fill out the NHDPlus HR QC interest Google form to participate in the NHDPlus HR Beta review/QC process. For more information on NHDPlus HR, please see the NHDPlus HR webpage.

Hydro Fun Fact from Elizabeth Smith, Bureau of Water, Kansas Department of Health and Environment

January 29 was Kansas Day. The state song mentions not one, but TWO waterbodies by name – Beaver Creek and Solomon River. And what is the Kansas state song? None other than Home on the Range! https://en.wikipedia.org/wiki/Home_on_the_Range Thanks Elizabeth!

NHDPlus Medium Resolution Update Contact: Tommy Dewald ([email protected])

There are several new and improved medium resolution NHDPlus products and services available - including new user applications, updates to training materials, and new visualization capabilities. The User Applications section on the NHDPlus web site (https://www.epa.gov/waterdata/nhdplus-applications) has been updated with over 50 new entries adding to the rich collection found there. Click on the Date Posted column heading to sort the most recent entries to the top of the table. As always, your additions, which benefit the larger water resources community by sharing with others what's possible with NHDPlus, are welcomed and encouraged. While visiting the site, you might also check out the additions to the training materials including the presentation videos and a comprehensive self-directed companion exercise from the 2016 NHDPlus Workshop. See https://www.epa.gov/waterdata/nhdplus-national-hydrography-dataset-plus, click on the Learn More tab, then expand the Documentation item. On the EPA Watershed Assessment, Tracking and Environmental Results (WATERS) web site, you'll find the new WATERS GeoViewer which leverages ArcGIS Online and the EPA GeoPlatform to provide upstream/downstream search, watershed delineation and an enhanced watershed report service featuring dynamic access to the extensive StreamCat library of landscape attributes. The underlying NHDPlus-based web services are available for general access as well. See https://www.epa.gov/waterdata/waters-watershed-assessment-tracking-environmental-results-system, then click on the Get Data/Tool tab. It's exciting to deliver these capabilities which are expected to enable even more creative applications of the existing medium resolution NHDPlus, while production of the new NHDPlus High Resolution continues to progress (https://nhd.usgs.gov/NHDPlus_HR.html). If you would like to receive periodic email updates about the availability of medium resolution NHDPlus data, tools and updates, please send your name, phone

Provisional Names Pilot Project Ending Contact: Michael Tinker ([email protected])

The USGS is ending the Provisional Names pilot project. Unfortunately, the tool did not adequately fulfill its intended use, and the beta Provisional Names Add-In tool for ArcMap and corresponding web service will no longer be supported or available for use. This tool allowed NHD stewards to submit a name and link to supporting documentation for unnamed features in the NHD during the editing of an active NHD job. Partners who have been using the beta Provisional Names Add-In tool are requested to please uninstall it from ArcMap. The USGS is looking at alternative options that can cover the important function and workflow of the Provisional Names tool. Thanks to those who were a part of the Provisional Names pilot project. Your work is helping to guide the creation of an improved solution. For questions, please contact Michael Tinker ([email protected]).
