map_nhdplus() works much the same as plot_nhdplus() but creates a leaflet map rather than a static plot.get_flowline_index() and get_waterbody_index() units and projection handling was altered. Defaults for the search_radius input were changed. Coordinate reference system handling in geoprocessing now relies on the CRS of the provided points rather than the flowlines.This is a very minor release required by CRAN checks.
Some scalability issues in plot_nhdplus() were identified and fixed.
get_raindrop_trace(), get_split_catchment() use a web service to access elevation data and retireve a raindrop trace path to the nearest flowline in nhdplus V2 and a split catchment or basin to a precise point location respectively.get_xs_point(), get_xs_points(), and get_elev_along_path() access an elevation data service from the 3D Elevation Program and return cross section / path elevation data.New functions st_compatibalize() and rename_geometry() provide utility functionality to make two layers compatible, including projection and rename geometry columns respectively.
New function get_sorted() generates a sorted and optionally partitioned version of a dendritic tree.
subset_vpu() wraps subset_rpu() and will subset a vector procesing unit.fix_flowdir() will re-order geometry nodes such that their order cooresponds to the convention used in nhdplus data.get_vaa() will now return an updated nhdplus network attribute set derived from multiple improved sources.navigate_network() provides a wrapper around a number of network navigation capabilities and will support local or web service data.get_tocomid() encapsulates a suite of functionality for converting edge node network representations to edge list format.get_path_lengths() finds network distances between pairs of points.get_partial_length() finds flowpath length up and downstream of a hydrologic location.plot_nhdplus() now includes on network and off network waterbodies.get_wb_outlet() finds the outlet flowline of an on-network waterbody. This function works for both nhdplusV2 and hires.testthat edition 3.igraph package is no longer a dependency. All graph algorithms have been implemented in base R for performance and simplicity.New function added: get_streamlevel() calculates stream level, a bottom up level path order used by nhdplus to categorize complete river levels.
nhdplusTools internals have started to be refactored to use all lower case attribute names. No changes should be seen from outside the package, but please report issues with attribute naming.
Package testing now runs in parallel and uses revision 3 of the testthat package.
Version 0.4.2 further cleans up temporary and cache data functionality for CRAN policy.
New functionality was added to indexing functionality.
disambiguate_flowline_indexes() supports for disambiguating them based on numeric or text attributes that should match. This functionality is not heavily tested, but forms a basis for expansion of this functionality going forward.get_hydro_location() was added. It will return point geometry given a geometry identifier and measure along that identifier.Version 0.4.1 is a minor release with bug fixes and updates for CRAN policy.
A noteable addition is handling for strictly dendritic topology encoded using a “tocomid” attribute rather than “fromnode” and “tonode” attributes. This functionality was added in subsetting functions and is backward compatible with previous versions.
Version 0.4.0 adds new functionality for data access via web services and updates the usability and flexibility of data discovery and subsetting functions. This release includes significant rework of functions related to network navigation and web-service data subsetting.
subset_nhdplus() included internal functionality for downloading data via web service. This code for subsetting NHDPlus via web service was completely rewritten and a number of new web-service data access functions were added. The get_nhdplus() function has been added and is for web-service data access only. subset_nhdplus(), which will output a subset to a local .gpkg file, now uses get_nhdplus() for download functionality.navigate_nldi() and most other NLDI functions are now based on an NLDI client in the dataRetrieval package. Functionality has been maintained backward compatible with nhdplusTools v0.3 as much as possible with some minor modifications to accomadate changes in dataRetrieval. The response format from navigate_nldi() has been changed slightly in v0.4, it now includes both the origin feature and navigation type(s) as a list. Two un-needed nldi discovery functions were removed..fst file) for use in network navigation and other applications have been added. These can be used with any nhdplusTools functions that do not require geometry.get_levelpaths() now has an override_factor parameter that will cause stream leveling to follow the weight rather than the name input if the weight is override_factor times larger than the name indication.Functions Added * get_nhdplus() * get_nhdarea() * get_waterbodies() * get_gagesII() * get_huc12() * get_huc8() * download_vaa() * get_vaa() * get_vaa_names() * get_vaa_path()
Functions Removed * discover_nldi_navigation() * discover_nldi_sources()
Functions Deprecated * stage_national_data()
Functions with Consolodated Internals * discover_nhdplus_id() * get_nldi_basin() * get_nldi_feature() * subset_nhdplus() * plot_nhdplus()
Finally, the handling of data and caching in the package has been overhauled. These changes are non-functional, but aim to decrease data downloads by caching rather than using temp directories.
subset_nhdplus() now validates geometry and ensures all outputs are in NAD83subset_nhdplus() queries the NHDPlus database rather than loading then filteringget_levelpaths() rewritten for performance. Package now uses data.table.discover_nldi_characteristics() and get_nldi_characteristics()navigate_nldi() to use the new NLDI navigation end point. Distance is now required.get_flowline_index() to handle multipart lines.plot_nhdplus() to improve scalabilitysubset_nhdplus() for download filtering.plot_nhdplus() updated to improve scalability of large downloads.get_node() to get top and bottom of a flowline.subset_rpu() to enable subsetting the NHD by Raster Processing Unitget_waterbody_index() to find associations between point locations and waterbodys.get_flowline_index() with max_matches parameter.get_flowline_index() rather than requiring data to be loaded locally.plot_nhdplus() with both outlet-based and bbox based data subsetting as well as rudimentary style modification capabilities.get_streamorder() and get_pfaf()) for dendritic networks.subset_nhdplus() can now return data without writing a file to disk.get_nhdplushr() has been updated to modify terminal path and other identifiers making nhdplusHR subsets “stand alone”. A function make_standalone() is now exported.get_terminal() and get_pathlength() functions to generate nhdplus network attributes.
