0.16.2 (2024-02-12)#

Bug Fixes#

  • In NLDI.get_basins, the indices used to be station IDs but in the previous release they were reset by mistake. This version retains the correct indices.

New Features#

  • In nhdplus_l48 function, when the layer is NHDFlowline_Network or NHDFlowline_NonNetwork, merge all MultiLineString geometries to LineString.

0.16.1 (2024-01-03)#

Bug Fixes#

  • Fix an issue in network_xsection and flowline_xsection related to the changes in shapely 2 API. Now, these functions should return the correct cross-sections.

0.16.0 (2024-01-03)#

New Features#

  • Add access to USGS 3D Hydrography Program (3DHP) service. The new class is called HP3D. It can be queried by IDs, geometry, or SQL where clause.

  • Add support for the new PyGeoAPI endpoints called xsatpathpts. This new endpoint is useful for getting elevation profile along A shapely.LineString. You can use pygeoapi function with service="elevation_profile" (or PyGeoAPI class) to access this new endpoint. Previously, the elevation_profile endpoint was used for getting elevation profile along a path from two endpoints and the input GeoDataFrame must have been a MultiPoint with two coordinates. Now, you must the input must contain LineString geometries.

  • Switch to using the new smoothing algorithm from pygeoutils for resampling the flowlines and getting their cross-sections. This new algorithm is more robust, accurate, and faster. It has a new argument called smoothing for controlling the number knots of the spline. Higher values result in smoother curves. The default value is None which uses all the points from the input flowline.

0.15.2 (2023-09-22)#

Bug Fixes#

  • Update GeoConnex based on the latest changes in the web service.

0.15.1 (2023-09-02)#

Bug Fixes#

  • Fix HyRiver libraries requirements by specifying a range instead of exact version so conda-forge can resolve the dependencies.

0.15.0 (2023-05-07)#

From release 0.15 onward, all minor versions of HyRiver packages will be pinned. This ensures that previous minor versions of HyRiver packages cannot be installed with later minor releases. For example, if you have py3dep==0.14.x installed, you cannot install pydaymet==0.15.x. This is to ensure that the API is consistent across all minor versions.

New Features#

  • Add a new function, called nhdplus_h12pp, for retrieving HUC12 pour points across CONUS.

  • Add use_arrow=True to pynhd.nhdplus_l48 when reading the NHDPlus dataset. This speeds up the process since pyarrow is installed.

  • In nhdplus_l48 make layer option so sql parameter of pyogrio.read_dataframe can also be used. This is necessary since pyogrio.read_dataframe does not support passing both layer and sql parameters.

  • Update the mainstems dataset link to version 2.0 in mainstem_huc12_nx.

  • Expose NHDTools class to the public API.

  • For now, retain compatibility with shapely<2 while supporting shapley>=2.

Bug Fixes#

  • Remove unnecessary conversion of id_col and toid_col to Int64 in nhdflw2nx and vector_accumulation. This ensures that the input data types are preserved.

  • Fix an issue in nhdplus_l48, where if the input data_dir is not absolute py7zr fails to extract the file.

0.14.0 (2023-03-05)#

New Features#

  • Rewrite the GeoConnex class to provide access to new capabilities of the web service. Support for spatial queries have been added via CQL queries. For more information, check out the updated GeoConnex example notebook.

  • Add a new property to StreamCat, called metrics_df that gets a dataframe of metric names and their description.

  • Create a new private StreamCatValidator class to avoid polluting the public StreamCat class with private attributes and methods. Moreover, add a new alternative metric names attribute to StreamCat called alt_names for handling those metric names that do not follow METRIC+YYYY convention. This attribute is a dictionary that maps the alternative names to the actual metric names, so users can use METRIC_NAME column of metrics_df and add a year suffix from valid_years attribute of StreamCat to get the actual metric name.

  • In navigate_by* functions of NLDI add stop_comid, which is another criterion for stopping the navigation in addition to distance.

  • Improve UserWarning messages of NLDI and WaterData.

Breaking Changes#

  • Remove pynhd.geoconnex function since more functionality has been added to the GeoConnex service that existence of this function does not make sense anymore. All queries should be done via pynhd.GeoConnex class.

  • Rewrite NLDI to improve code readability and significantly improving performance. Now, its methods do now return tuples if there are failed requests, instead they will be shown as a UserWarning.

  • Bump the minimum required version of shapely to 2.0, and use its new API.

Internal Changes#

  • Sync all minor versions of HyRiver packages to 0.14.0.

0.13.12 (2023-02-10)#

New Features#

  • Update the link to version 2.0 of the ENHD dataset in enhd_attrs.

Internal Changes#

  • Improve columns data types in enhd_attrs and nhdplus_vaa by using int32 instead of Int64, where applicable.

  • Sync all patch versions of HyRiver packages to x.x.12.

0.13.11 (2023-01-24)#

New Features#

  • The prepare_nhdplus now supports NHDPlus HR in addition to NHDPlus MR. It automatically detects the NHDPlus version based on the ID column name: nhdplusid for HR and comid for MR.

Internal Changes#

  • Fully migrate setup.cfg and setup.py to pyproject.toml.

  • Convert relative imports to absolute with absolufy-imports.

  • Improve performance of prepare_nhdplus by using pandas.merge instead of applying a function to each row of the dataframe.

0.13.10 (2023-01-08)#

New Features#

  • Add support for the new EPA’s StreamCat Restful API with around 600 NHDPlus catchment level metrics. One class is added for getting the service properties such as valid metrics, called StreamCat. You can use streamcat function to get the metrics as a pandas.DataFrame.

  • Refactor the show_versions function to improve performance and print the output in a nicer table-like format.

Internal Changes#

  • Skip 0.13.9 version so the minor version of all HyRiver packages become the same.

  • Modify the codebase based on the latest changes in geopandas related to empty dataframes.

0.13.8 (2022-12-09)#

New Features#

  • Add a new function, called nhdplus_attrs_s3, for accessing the recently released NHDPlus derived attributes on a USGS’s S3 bucket. The attributes are provided in parquet files, so getting them is faster than nhdplus_attrs. Also, you can request for multiple attributes at once whereas in nhdplus_attrs you had to request for each attribute one at a time. This function will replace nhdplus_attrs in a future release, as soon as all data that are available on the ScienceBase version are also accessible from the S3 bucket.

  • Add two new functions called mainstem_huc12_nx and enhd_flowlines_nx. These functions generate a networkx directed graph object of NHD HUC12 water boundaries and flowlines, respectively. They also return a dictionary mapping of COMID and HUC12 to the corresponding networkx node. Additionally, a topologically sorted list of COMIDs/HUC12s are returned. The generated data are useful for doing US-scale network analysis and flow accumulation on the NHD network. The NHD graph has about 2.7 million edges and the mainstem HUC12 graph has about 80K edges.

  • Add a new function for getting the entire NHDPlus dataset for CONUS (Lower 48), called nhdplus_l48. The entire NHDPlus dataset is downloaded from here. This 7.3 GB file will take a while to download, depending on your internet connection. The first time you run this function, the file will be downloaded and stored in the ./cache directory. Subsequent calls will use the cached file. Moreover, there are two additional dependencies for using this function: pyogrio and py7zr. These dependencies can be installed using pip install pyogrio py7zr or conda install -c conda-forge pyogrio py7zr.

Internal Changes#

  • Refactor vector_accumulation for significant performance improvements.

  • Modify the codebase based on Refurb suggestions.

0.13.7 (2022-11-04)#

New Features#

  • Add a new function called epa_nhd_catchments to access one of the EPA’s HMS endpoints called WSCatchment. You can use this function to access 414 catchment-scale characteristics for all the NHDPlus catchments including 16-day average curve number. More information on the curve number dataset can be found at its project page here.

Bug Fixes#

  • Fix a bug in NHDTools where due to the recent changes in pandas exception handling, the NHDTools fails in converting columns with NaN values to integer type. Now, pandas throws IntCastingNaNError instead of TypeError when using astype method on a column.

Internal Changes#

  • Use pyupgrade package to update the type hinting annotations to Python 3.10 style.

0.13.6 (2022-08-30)#

Internal Changes#

  • Add the missing PyPi classifiers for the supported Python versions.

0.13.5 (2022-08-29)#

Breaking Changes#

  • Append “Error” to all exception classes for conforming to PEP-8 naming conventions.

Internal Changes#

  • Bump the minimum versions of pygeoogc and pygeoutils to 0.13.5 and that of async-retriever to 0.3.5.

Bug Fixes#

  • Fix an issue in nhdplus_vaa and enhd_attrs functions where if cache folder does not exist, it would not have been created, thus resulting to an error.

0.13.3 (2022-07-31)#

Internal Changes#

  • Use the new async_retriever.stream_write function to download files in nhdplus_vaa and enhd_attrs functions. This is more memory efficient.

  • Convert the type of list of not found items in NLDI.comid_byloc and NLDI.feature_byloc to list of tuples of coordinates from list of strings. This matches the type of returned not found coordinates to that of the inputs.

  • Fix an issue with NLDI that was caused by the recent changes in the NLDI web service’s error handling. The NLDI web service now returns more descriptive error messages in a json format instead of returning the usual status errors.

  • Slice the ENHD dataframe in NHDTools.clean_flowlines before updating the flowline dataframe to reduce the required memory for the update operation.

0.13.2 (2022-06-14)#

Breaking Changes#

  • Set the minimum supported version of Python to 3.8 since many of the dependencies such as xarray, pandas, rioxarray have dropped support for Python 3.7.

Internal Changes#

  • Use micromamba for running tests and use nox for linting in CI.

0.13.1 (2022-06-11)#

New Features#

  • Add support for all the GeoConnex web service endpoints. There are two ways to use it. For a single query, you can use the geoconnex function and for multiple queries, it’s more efficient to use the GeoConnex class.

  • Add support for passing any of the supported NLDI feature sources to the get_basins method of the NLDI class. The default is nwissite to retain backward compatibility.

Bug Fixes#

  • Set the type of “ReachCode” column to str instead of int in pygeoapi and nhdplus_vaa functions.

0.13.0 (2022-04-03)#

New Features#

  • Add two new functions called flowline_resample and network_resample for resampling a flowline or network of flowlines based on a given spacing. This is useful for smoothing jagged flowlines similar to those in the NHDPlus database.

  • Add support for the new NLDI endpoint called “hydrolocation”. The NLDI class now has two methods for getting features by coordinates: feature_byloc and comid_byloc. The feature_byloc method returns the flowline that is associated with the closest NHDPlus feature to the given coordinates. The comid_byloc method returns a point on the closest downstream flowline to the given coordinates.

  • Add a new function called pygeoapi for calling the API in batch mode. This function accepts the input coordinates as a geopandas.GeoDataFrame. It is more performant than calling its counteract PyGeoAPI multiple times. It’s recommended to switch to using this new batch function instead of the PyGeoAPI class. Users just need to prepare an input data frame that has all the required service parameters as columns.

  • Add a new step to prepare_nhdplus to convert MultiLineString to LineString.

  • Add support for the simplified flag of NLDI’s get_basins function. The default value is True to retain the old behavior.

Breaking Changes#

  • Remove caching-related arguments from all functions since now they can be set globally via three environmental variables:

    • HYRIVER_CACHE_NAME: Path to the caching SQLite database.

    • HYRIVER_CACHE_EXPIRE: Expiration time for cached requests in seconds.

    • HYRIVER_CACHE_DISABLE: Disable reading/writing from/to the cache file.

    You can do this like so:

import os

os.environ["HYRIVER_CACHE_NAME"] = "path/to/file.sqlite"
os.environ["HYRIVER_CACHE_EXPIRE"] = "3600"
os.environ["HYRIVER_CACHE_DISABLE"] = "true"

0.12.2 (2022-02-04)#

New Features#

  • Add a new class called NHD for accessing the latest National Hydrography Dataset. More info regarding this data can be found here.

  • Add two new functions for getting cross-sections along a single flowline via flowline_xsection or throughout a network of flowlines via network_xsection. You can specify spacing and width parameters to control their location. For more information and examples please consult the documentation.

  • Add a new property to AGRBase called service_info to include some useful info about the service including feature_types which can be handy for converting numeric values of types to their string equivalent.

Internal Changes#

  • Use the new PyGeoAPI API.

  • Refactor prepare_nhdplus for improving the performance and robustness of determining tocomid within a network of NHD flowlines.

  • Add empty geometries that NLDI.getbasins returns to the list of not found IDs. This is because the NLDI service does not include non-network flowlines and instead returns an empty geometry for these flowlines. (GH #48)

0.12.1 (2021-12-31)#

Internal Changes#

  • Use the three new ar.retrieve_* functions instead of the old ar.retrieve function to improve type hinting and to make the API more consistent.

  • Revert to the original PyGeoAPI base URL.

0.12.0 (2021-12-27)#

Breaking Changes#

  • Rewrite ScienceBase to make it applicable for working with other ScienceBase items. A new function has been added for staging the Additional NHDPlus attributes items called stage_nhdplus_attrs.

  • Refactor AGRBase to remove unnecessary functions and make them more general.

  • Update PyGeoAPI class to conform to the new pygeoapi API. This web service is undergoing some changes at the time of this release and the API is not stable, might not work as expected. As soon as the web service is stable, a new version will be released.

New Features#

  • In WaterData.byid show a warning if there are any missing feature IDs that are requested but are not available in the dataset.

  • For all by* methods of WaterData throw a ZeroMatched exception if no features are found.

  • Add expire_after and disable_caching arguments to all functions that use async_retriever. Set the default request caching expiration time to never expire. You can use disable_caching if you don’t want to use the cached responses. Please refer to documentation of the functions for more details.

Internal Changes#

  • Refactor prepare_nhdplus to reduce code complexity by grouping all the NHDPlus tools as a private class.

  • Modify AGRBase to reflect the latest API changes in pygeoogc.ArcGISRESTfull class.

  • Refactor prepare_nhdplus by creating a private class that includes all the previously used private functions. This will make the code more readable and easier to maintain.

  • Add all the missing types so mypy --strict passes.

0.11.4 (2021-11-12)#

New Features#

  • Add a new argument to NLDI.get_basins called split_catchment that if is set to True will split the basin geometry at the watershed outlet.

Internal Changes#

  • Catch service errors in PyGeoAPI and show useful error messages.

  • Use importlib-metadata for getting the version instead of pkg_resources to decrease import time as discussed in this issue.

0.11.3 (2021-09-10)#

Internal Changes#

  • More robust handling of inputs and outputs of NLDI’s methods.

  • Use an alternative download link for NHDPlus VAA file on Hydroshare.

  • Restructure the codebase to reduce the complexity of pynhd.py file by dividing it into three files: pynhd all classes that provide access to the supported web services, core that includes base classes, and nhdplus_derived that has functions for getting databases that provided additional attributes for the NHDPlus database.

0.11.2 (2021-08-26)#

New Features#

  • Add support for PyGeoAPI. It offers four functionalities: flow_trace, split_catchment, elevation_profile, and cross_section.

0.11.1 (2021-07-31)#

New Features#

  • Add a function for getting all NHD FCodes as a data frame, called nhd_fcode.

  • Improve prepare_nhdplus function by removing all coastlines and better detection of the terminal point in a network.

Internal Changes#

  • Migrate to using AsyncRetriever for handling communications with web services.

  • Catch the ConnectionError separately in NLDI and raise a ServiceError instead. So user knows that data cannot be returned due to the out of service status of the server not ZeroMatched.

0.11.0 (2021-06-19)#

New Features#

  • Add nhdplus_vaa to access NHDPlus Value Added Attributes for all its flowlines.

  • To see a list of available layers in NHDPlus HR, you can instantiate its class without passing any argument like so NHDPlusHR().

Breaking Changes#

  • Drop support for Python 3.6 since many of the dependencies such as xarray and pandas have done so.

Internal Changes#

  • Use persistent caching for all requests which can help speed up network responses significantly.

  • Improve documentation and testing.

0.10.1 (2021-03-27)#

  • Add an announcement regarding the new name for the software stack, HyRiver.

  • Improve pip installation and release workflow.

  • Make mypy checks more strict and fix all the errors and prevent possible bugs.

  • Speed up CI testing by using mamba and caching.

0.9.0 (2021-02-14)#

  • Bump version to the same version as PyGeoHydro.

Breaking Changes#

  • Add a new function for getting basins geometries for a list of USGS station IDs. The function is a method of NLDI class called get_basins. So, now NLDI.getfeature_byid function does not have a basin flag. This change makes getting geometries easier and faster.

  • Remove characteristics_dataframe method from NLDI and make a standalone function called nhdplus_attrs for accessing NHDPlus attributes directly from ScienceBase.

  • Add support for using hydro or edits webs services for getting NHDPlus High-Resolution using NHDPlusHR function. The new arguments are service which accepts hydro or edits, and autos_switch flag for automatically switching to the other service if the ones passed by service fails.

New Features#

  • Add a new argument to topoogical_sort called edge_attr that allows adding attribute(s) to the returned Networkx Graph. By default, it is None.

  • A new base class, AGRBase for connecting to ArcGISRESTful-based services such as National Map and EPA’s WaterGEOS.

  • Add support for setting the buffer distance for the input geometries to AGRBase.bygeom.

  • Add comid_byloc to NLDI class for getting ComIDs of the closest flowlines from a list of lon/lat coordinates.

  • Add bydistance to WaterData for getting features within a given radius of a point.

0.2.0 (2020-12-06)#

Breaking Changes#
