nhdplusTools 1.2.1

Bug fix for data cache directory #389

nhdplusTools 1.2.0

This release introduces a new data source: https://reference.geoconnex.us and a vignette providing a broad overview of data access with nhdplusTools.

Fixed bug with use of memoise cache #365
Added vignette("get_data_overview") for WaterSciCon24
Added get_geoconnex_reference() and discover_geoconnex_reference()

nhdplusTools 1.1.0

This release has a significant consolidation of code to work with web services. It incorporates an ArcGIS REST service for the first time. It has very few backward compatibility issues with previous versions and introduces new functions and behavior.

A key change in behavior is the introduction of caching with the memoise package. See #366, pull request #364, and documentation in nhdplusTools_cache_settings() for more.

fixed nhd and nhdplushr urls #368
fix issue with nhdplusTools_data_dir() #365
fixed bug with large nhdplus downloads with empty tiles. #361
Added 3DHP_all service client. #363
Removed deprecated function get_huc12 and get_huc8
Updated documentation of get_huc() and other web service functions.
added nhdplusTools_cache_settings() to control use of a memoise cache. #366
fix minor bug related to binding nhdplushr data together. #380

nhdplusTools 1.0.0

nhdplusTools has been split into two packages. A new package hydroloom is now available. It contains all nhdplusTools functionality not related to specific dataset schemas. See this issue for details.

`hydroloom`

v1.0.0 should be backward compatible with v0.7 but deprecation warnings have been added and one previously deprecated function has been removed.

This release evolves nhdplusTools to use hydroloom as a core dependency. nhdplusTools now depends on hydroloom for all network navigation and indexing functionality that is not specific to the nhdplus data model or specific to a US-context.

Specific functions imported from hydroloom include:

hy
accumulate_downstream
add_levelpaths
add_pathlength
add_pfafstetter
add_streamlevel
add_streamorder
add_toids
disambiguate_indexes
fix_flowdir
get_hydro_location
get_node
get_partial_length
index_points_to_lines
index_points_to_waterbodies
make_fromids
make_index_ids
navigate_connected_paths
navigate_hydro_network
rename_geometry
rescale_measures
sort_network
st_compatibalize

See the hydroloom reference list for details about these functions.

With these functions migrated to hydroloom, a number of nhdplusTools functions are now deprecated in favor of the hyroloom implementation.

make_node_topology()
get_pfaf()
get_path_members()
get_path_lengths()
get_levelpaths()
get_terminal()
make_node_topology()

In v1.0.0, the download_nhd() function was added.

In v1.0.0, the stage_national_data (previously deprecated) function was removed.

nhdplusTools 0.7.1

This release fixes a minor example issue for CRAN checks

nhdplusTools 0.7.0

This release adds three new functions.

get_characteristics_metadata()
get_catchment_characteristics()
rescale_catchment_characteristics()

These functions are designed to provide access to:

Wieczorek, M.E., Jackson, S.E., and Schwarz, G.E., 2018, Select Attributes for NHDPlus Version 2.1 Reach Catchments and Modified Network Routed Upstream Watersheds for the Conterminous United States (ver. 3.0, January 2021): U.S. Geological Survey data release, .

See https://github.com/DOI-USGS/nhdplusTools/issues/304 and https://github.com/DOI-USGS/nhdplusTools/issues/303 for details.

Update a test for a change in sf

nhdplusTools 0.6.1

No functional changes. Package migrated to new repository: https://github.com/DOI-USGS/nhdplusTools

nhdplusTools 0.6.0

minor change to behavior of navigate_nldi the “origin” will always be named as such rather than the named 1-element list being dropped to a data.frame. https://github.com/DOI-USGS/dataRetrieval/issues/623
Address scalability issue with web service downloads. #308
Add ability to add node topology back to a edge list topology. #302

nhdplusTools 0.5.7

Update reference for updated flowline attributes.
Fix failing example for cran checks.

nhdplusTools 0.5.6

Update URL for NHDPlusV2 download
make geometry validity checks more robust

nhdplusTools 0.5.4 & v0.5.5

Note v0.5.4 was burned in a CRAN release mistake

fixes a cran test failure in an example and an issue with precision of get_flowline_index()

nhdplusTools 0.5.3

v0.5.3 is primarily bug fixes and enhancements.

One notable addition is the addition of the rpu_boundaries and vpu_boundaries datasets which provide simplified polygons around the RPU and VPU subset domains of the NHDPlusV2 dataset.

nhdplusTools 0.5.2

Mike Johnson is now recognized as an author of nhdplusTools.

New Functions

map_nhdplus() works much the same as plot_nhdplus() but creates a leaflet map rather than a static plot.
get_nldi_index() is used to call the NLDI web service to retrieve a hydrologic location.

Improvements

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.
get_nldi_basin() now supports precise basin delineation via a logical “split” parameter as well as the option to retrieve un-simplified basin geometry.
All network-dependent functions in nhdplusTools now return a warning and NULL if the web service is unavailable or fails for other reasons. This is according to CRAN policy.

nhdplusTools 0.5.1

This is a very minor release required by CRAN checks.

Some scalability issues in plot_nhdplus() were identified and fixed.

nhdplusTools 0.5.0

Documentation updates

A new “advanced network attributes” vignette was added.
All vignettes were revisited to ensure they are up to date.
The introduction vignette is now very brief with links to others.

Web Service Wrapper Functions

New functions get_raindrop_trace(), get_split_catchment() use a web service to access elevation data and retrieve a raindrop trace path to the nearest flowline in nhdplus V2 and a split catchment or basin to a precise point location respectively.
New functions 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.

Utility Functions

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.

Subsetting and data utilities

New function subset_vpu() wraps subset_rpu() and will subset a vector processing unit.
New function fix_flowdir() will re-order geometry nodes such that their order corresponds to the convention used in nhdplus data.
get_vaa() will now return an updated nhdplus network attribute set derived from multiple improved sources.

New function navigate_network() provides a wrapper around a number of network navigation capabilities and will support local or web service data.
New function get_tocomid() encapsulates a suite of functionality for converting edge node network representations to edge list format.
New function get_path_lengths() finds network distances between pairs of points.
New function get_partial_length() finds flowpath length up and downstream of a hydrologic location.

Plotting

plot_nhdplus() now includes on network and off network waterbodies.
New function get_wb_outlet() finds the outlet flowline of an on-network waterbody. This function works for both NHDPlusV2 and hires.

Package Internals

nhdplusTools testing has been updated to use testthat edition 3.
All terminal “toID” values are 0 rather than NA to avoid confusion with a mix of both.
igraph package is no longer a dependency. All graph algorithms have been implemented in base R for performance and simplicity.
Many package functions have been converted to use lowercase attributes. Attribute naming is settling into two modes – ID, toID, and lowercase otherwise – and comid, tocomid, and lowercase. The ID syntax is meant to be a temporary ID while comid is meant to be some external identifier that should be treated as such.
The master branch was renamed main.

nhdplusTools 0.4.3

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.

nhdplusTools 0.4.2

Version 0.4.2 further cleans up temporary and cache data functionality for CRAN policy.

New functionality was added to indexing functionality.

When multiple flowlines are returned, 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.
A function to find the point location of a flowline index, get_hydro_location() was added. It will return point geometry given a geometry identifier and measure along that identifier.

nhdplusTools 0.4.1

Version 0.4.1 is a minor release with bug fixes and updates for CRAN policy.

A notable 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.

nhdplusTools 0.4.0

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.

Previously, 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 accommodate 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.
Functions to download and cache all NHDPlus VAAs (in a 195mb .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 Consolidated 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.
