The nhdplusTools package contains a wide range of hydrographic data utilities. Many are globally-applicable hydrographic data manipulation and processing tools. Others are specific to a U.S. context, focused on particular US datasets and sources.
Detailed documentation of all the package functions can be found at the Reference page.
For data discovery and access in a U.S. context, start with the
US Data vignette vignette("US_data").
For globally applicable functions, start with the advanced
network attributes vignette
vignette("advanced_network").
