Abstract:
The USGS is excited to announce the release of the GeoPackage format for all Hydrography downloadable products, including the NHD, WBD, and NHDPlus High Resolution. The USGS has chosen to distribute downloadable data in the GeoPackage format in support of the OPEN Government Data Act and Geospatial Data Act, which require government data to be available in an open format and to use open and international standards when possible. GeoPackage data is platform agnostic and can be utilized by a variety of commercial off the shelf and open-source software packages. This presentation will cover the basics of the GeoPackage format and associated changes for Hydrography data.
