nhdplusTools 0.5.2
==========

## New Function
- `map_nhdplus()` works much the same as `plot_nhdplus()` but creates a leaflet map rather than a static plot.

## 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.

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 retireve 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 procesing unit.
- New function `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.

## Network Navigation and Attributes
- 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](https://github.com/USGS-R/nhdplusTools/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 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.

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. 

* Previsouly, `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](https://waterdata.usgs.gov/blog/nldi-intro/) functions are now based on an NLDI client in the [`dataRetrieval`](https://code.usgs.gov/water/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.
* 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 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.

nhdplusTools 0.3.16
==========
* `subset_nhdplus()` now validates geometry and ensures all outputs are in NAD83
