0.19.4 (2025-05-23)

Bug Fixes

  • Fix the download URL for get_camels function according to the changes in the Hydroshare web service.
  • Use the new links for the eHydro web service.
  • Fix the download issue with the Census data in get_us_states function.

0.19.3 (2025-03-07)

New Features

  • Add support for POLARIS soil dataset. The new function is called soil_polaris. The function returns soil properties from the POLARIS dataset for a given location. The dataset includes soil properties such as soil texture, bulk density, organic carbon, pH, and soil moisture. The dataset is available for CONUS at 30m resolution.

Internal Changes

  • Make matplotlib and folium optional dependencies instead of required dependencies. This is to reduce the size of the package and make it more lightweight. They are now required only if the plot module is used.
  • Move the plotting functionality of PyGeoHydro for hydrologic signatures to HydroSignatures package. For now, the plot module is exported from HydroSignatures package to maintain backward compatibility.

0.19.0 (2025-01-17)

Internal Changes

  • Update all dependencies on HyRiver libraries to the latest versions and modify the code to be compatible with the latest versions of the libraries.

0.18.0 (2024-10-05)

Bug Fixes

  • Bump the minimum version of aiohttp-client-cache>=0.12.3 to fix an issue with the latest version of aiohttp. (:issue_hydro:`124`)

Breaking Changes

  • Drop support for Python 3.8 since its end-of-life date is October 2024.
  • Remove all exceptions from the main module and raise them from the exceptions module. This is to declutter the public API and make it easier to maintain.

0.17.1 (2024-09-14)

Internal Changes

  • Drop support for Python 3.8 since its end-of-life date is October 2024.

Bug Fixes

  • Update the nlcd module to reflect the changes in the MRLC web service. There have been some breaking changes in the NLCD web service, and the module is updated to reflect these changes. Thus, previous versions of the module will not work with the new NLCD web service. (:issue_hydro:`122`)
  • Update the nid module based on the latest changes to the NID web service. The changes include the addition of new fields to the NID dataset and the removal of some fields. The module is updated to reflect these changes.
  • Update the nfhl module to reflect the changes in the NFHL web service. There have been some breaking changes in the NFHL web service, and the module is updated to reflect these changes. Thus, previous versions of the module will not work with the new NFHL web service.

0.17.0 (2024-05-07)

New Features

  • Add support for the National Levee Dataset (NLD) from the USACE. The new class is called NLD and gives users the ability to subset the NLD dataset by geometry, ID, or SQL queries. The class has three methods: bygeom, byids, and bysql.

Enhancements

  • Add a new argument to EHydro for passing a directory to store the raw downloaded data. This is useful since most times the raw data is needed for further processing and reuse. So, by storing them in a folder other than its previous default location, i.e., ./cache, users can easily access and manage them.

Internal Changes

  • Add the exceptions module to the high-level API to declutter the main module. In the future, all exceptions will be raised from this module and not from the main module. For now, the exceptions are raised from both modules for backward compatibility.
  • Switch to using the src layout instead of the flat layout for the package structure. This is to make the package more maintainable and to avoid any potential conflicts with other packages.
  • Add artifact attestations to the release workflow.
  • Move NID class to the nid module to make the package more organized and the main module less cluttered.

0.16.5 (2024-05-26)

New Features

  • Add new function called soil_soilgrids to get soil data from the SoilGrids dataset. The signature of the function is the same as of the soil_gnatsgo function, so they can be used interchangeably. For more information on the SoilGrids dataset, visit ISRIC.

0.16.4 (2024-05-20)

Bug Fixes

  • Fix an issue in NID.stage_nid_inventory where the function was failing when the response status code was 206 (partial content). This issue is fixed by checking the response status code and if it's 206, the function will continue reading the headers and the get the modified date from the response headers. Also, the function incorrectly didn't check if the local database was up-to-date with the remote database when the processed database already existed. Now, the function will check changes in the remote database and re-download the data even if necessary even if the processed database exists.

0.16.3 (2024-05-16)

Internal Changes

  • More robust handling of failed download links for eHydro data. For example, sometimes, eHydro web service uses placeholder as actual links. There are also cases where links are in the database but they are dead.
  • Add the exceptions module to the high-level API to declutter the main module. In the future, all exceptions will be raised from this module and not from the main module. For now, the exceptions are raised from both modules for backward compatibility.

Bug Fixes

  • In EHydro class, sometimes the requested surveys are not in the same CRS, so they couldn't be combined into a single GeoDataFrame. This issue is fixed by reprojecting all the requested surveys to 5070 CRS before combining them.

0.16.1 (2024-04-24)

Bug Fixes

  • In nlcd_helper function the roughness value for class 82 was set to 0.16 instead of 0.037.

New Features

  • Converted all methods of NWIS class to classmethod so the class can be used without instantiating it. This change makes the class more flexible and easier to use.
  • In NID class, the stage_nid_inventory method now checks if the remote NID database has been modified since the last download and only downloads the new data if it has been modified. This change makes the method more efficient and reduces the network traffic while ensuring that the local database is always up-to-date.

0.16.0 (2024-01-03)

Breaking Changes

  • Bump the minimum supported version of shapely to 2.

Internal Changes

  • Update the link to NWIS error codes tables in the nwis_errors function.
  • Update NWIS class based on the latest changes to the NWIS web service.
  • Use the default tiles for the interactive_map function.

0.15.2 (2023-09-22)

New Features

  • Add a new attribute to EHydro class called survey_grid. It's a geopandas.GeoDataFrame that includes the survey grid of the eHydro dataset which is a 35-km hexagonal grid.
  • Add support for getting point cloud and survey outline data from eHydro. You can set data_type in EHydro to bathymetry, points, outlines, or contours to get the corresponding data. The default is points since this is the recommended data type by USACE.
  • Add NFHL class within nfhl module to access FEMA's National Flood Hazard Layer (NFHL) using six different ArcGISRESTFul services. Contributed by Fernando Aristizabal. (:pull_hydro:`108`)

Internal Changes

  • Remove dependency on dask.
  • Move all NLCD related functions to a separate module called nlcd. This doesn't affect the API since the functions are still available under pygeohydro namespace.

0.15.1 (2023-08-02)

This release provides access to three new datasets:

New Features

  • Add support for getting topobathymetry data from USACE Hydrographic Surveys (eHydro). The new class is called EHydro and gives users the ability to subset the eHydro dataset by geometry, ID, or SQL queries.
  • Add new stnfloodevents module with STNFloodEventData class for retrieving flood event data from the USGS Short-Term Network (STN) RESTful Service. This Python API abstracts away RESTful principles and produces analysis ready data in geo-referenced GeoDataFrames, DataFrames, lists, or dictionaries as desired. The core class methods available are data_dictionary, get_all_data, and get_filtered_data. These class methods retrieve the data dictionaries by type, get all the available data by type, and make filtered requests for data by type as well, respectively. The four types of data include instruments, peaks, hwms, and sites. Contributed by Fernando Aristizabal.
  • Add a wrapper function for the STNFloodEventData class called stn_flood_event.
  • Add support for the new NLCD data (2021) for the three supported layers.

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 option to NWIS.get_info, called nhd_info, for retrieving NHDPlus related info on the sites. This will two new service calls that might slow down the function, so it's disabled by default.
  • Update links in NID to the latest CSV and GPKG versions of the NID dataset.
  • Add two new properties to NID to access the entire NID dataset. You can use NID.df to access the CSV version as a pandas.DataFrame and NID.gdf to access the GPKG version as a geopandas.GeoDataFrame. Installing pyogrio is highly recommended for much faster reading of the GPKG version.
  • Refactor NID.bygeom to use the new NID.gdf property for spatial querying of the dataset. This change should make the query much faster.
  • For now, retain compatibility with shapely<2 while supporting shapley>=2.

0.14.0 (2023-03-05)

New Features

  • Add a new function, called nlcd_area_percent, for computing the percentages or natural, developed, and impervious areas within geometries of a given GeoDataFrame. This function uses imperviousness and land use/land cover data from NLCD to compute the area percentages of the natural, developed, and impervious areas. For more information please refer to the function's documentation.
  • Add a new column to the dataframe returned by NWIS.get_info, called nhd_comid, and rename drain_sqkm to nhd_areasqkm. The new drainage area is the best available estimates of stations' drainage area that have been extracted from the NHDPlus. The new nhd_comid column makes it easier to link stations to NHDPlus.
  • In get_camels, return qobs with negatives values set to NaN. Also, Add a new variable called Newman_2017 to both datasets for identifying the 531 stations that were used in Newman et al. (2017).
  • Add a new function, called streamflow_fillna, for filling missing streamflow values (NAN) with day-of-year average values.

Breaking Changes

  • 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.
  • Improve performance of all NLCD functions by merging two methods of the NLCD and also reducing the memory footprint of the functions.

0.13.12 (2023-02-10)

New Features

  • Add initial support for SensorThings API Currently, the SensorThings class only supports Things endpoint. Users need to provide a valid Odata filter. The class has a odata_helper function that can be used to generate and validate Odata filters. Additionally, using sensor_info and sensor_property functions users can request for information about sensors themselves or their properties.

Internal Changes

  • Simplify geometry validation by using pygeoutils.geo2polygon function in ssebopeta_bygeom.
  • Fully migrate setup.cfg and setup.py to pyproject.toml.
  • Convert relative imports to absolute with absolufy-imports.
  • Sync all patch versions of HyRiver packages to x.x.12.

0.13.10 (2023-01-09)

Breaking Changes

  • The NID service has changed some of its endpoints to use Federal ID instead of Dam ID. This change affects the NID.inventory_byid function. This function now accepts Federal IDs instead of dam IDs.

New Features

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

Internal Changes

  • Use the new pygeoogc.streaming_download function in huc_wb_full to improve performance and reduce code complexity.
  • 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.
  • Use pyright for static type checking instead of mypy and address all typing issues that it raised.

0.13.8 (2022-12-09)

New Features

  • Add a function called huc_wb_full that returns the full watershed boundary GeoDataFrame of a given HUC level. If only a subset of HUCs is needed the pygeohydro.WBD class should be used. The full dataset is downloaded from the National Maps' WBD staged products.
  • Add a new function called irrigation_withdrawals for retrieving estimated monthly water use for irrigation by 12-digit hydrologic unit in the CONUS for 2015 from ScienceBase.
  • Add a new property to NID, called data_units for indicating the units of NID dataset variables.
  • The get_us_states now accepts conus as a subset_key which is equivalent to contiguous.

Internal Changes

  • Add get_us_states to __init__ file, so it can be loaded directly, e.g., gh.get_us_states("TX").
  • Modify the codebase based on Refurb suggestions.
  • Significant performance improvements in NWIS.get_streamflow especially for large requests by refactoring the timezone handling.

Bug Fixes

  • Fix the dam types and purposes mapping dictionaries in NID class.

0.13.7 (2022-11-04)

New Features

  • Add a two new function for retrieving soil properties across the US:
    • soil_properties: Porosity, available water capacity, and field capacity,
    • soil_gnatsgo: Soil properties from the gNATSGO database.
  • Add a new help function called state_lookup_table for getting a lookup table of US states and their counties. This can be particularly useful for mapping the digit state_cd and county_cd that NWIS returns to state names/codes.
  • Add support for getting individual state geometries using get_us_states function by passing their two letter state code. Also, use TIGER 2022 data for the US states and counties instead of TIGER 2021.

Internal Changes

  • Remove proplot as a dependency and use matplotlib instead.

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.
  • Deprecate ssebopeta_byloc since it's been replaced with ssebopeta_bycoords since version 0.13.0.

Internal Changes

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

0.13.3 (2022-07-31)

New Features

  • Add a new argument to NID.inventory_byid class for staging the entire NID dataset prior to inventory queries. There a new public method called NID.stage_nid_inventory that can be used to download the entire NID dataset and save it as a feather file. This is useful inventory queries with large number of IDs and is much more efficient than querying the NID web service.

Bug Fixes

  • The background value in cover_statistics function should have been 127 not 0. Also, dropped the background value from the return statistics.

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

  • Remove USGS prefixes from the input station IDs in NWIS.get_streamflow function. Also, check if the remaining parts of the IDs are all digits and throw an exception if otherwise. Additionally, make sure that IDs have at least 8 chars by adding leading zeros (:issue_hydro:`99`).
  • Use micromamba for running tests and use nox for linting in CI.

0.13.1 (2022-06-11)

New Features

  • Add a new function called get_us_states to the helpers module for obtaining a GeoDataFrame of the US states. It has an optional argument for returning the contiguous states, continental states, commonwealths states, or US territories. The data are retrieved from the Census' Tiger 2021 database.
  • In the NID class keep the valid_fields property as a pandas.Series instead of a list, so it can be searched easier via its str accessor.

Internal Changes

  • Refactor the plot.signatures function to use proplot instead of matplotlib.
  • Improve performance of NWIS.get_streamflow by not validating the layer name when instantiating the WaterData class. Also, make the function more robust by checking if streamflow data is available for each station and throw a warning if not.

Bug Fixes

  • Fix an issue in NWIS.get_streamflow where -9999 values were not being filtered out. According to NWIS, these values are reserved for ice-affected data. This fix sets these values to numpy.nan.

0.13.0 (2022-04-03)

New Features

  • Add a new flag to nlcd_* functions called ssl for disabling SSL verification.
  • Add a new function called get_camels for getting the CAMELS dataset. The function returns a geopandas.GeoDataFrame that includes basin-level attributes for all 671 stations in the dataset and a xarray.Dataset that contains streamflow data for all 671 stations and their basin-level attributes.
  • Add a new function named overland_roughness for getting the overland roughness values from land cover data.
  • Add a new class called WBD for getting watershed boundary (HUC) data.
from pygeohydro import WBD

wbd = WBD("huc4")
hudson = wbd.byids("huc4", ["0202", "0203"])

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"

Internal Changes

  • Write nodata attribute using rioxarray in nlcd_bygeom since the clipping operation of rioxarray uses this value as the fill value.

0.12.4 (2022-02-04)

Internal Changes

  • Return a named tuple instead of a dict of percentages in the cover_statistics function. It makes accessing the values easier.
  • Add pycln as a new pre-commit hooks for removing unused imports.
  • Remove time zone info from the inputs to plot.signatures to avoid issues with the matplotlib backend.

Bug Fixes

  • Fix an issue in plot.signatures where the new matplotlib version requires a numpy array instead of a pandas.DataFrame.

0.12.3 (2022-01-15)

Bug Fixes

  • Replace no data values of data in ssebopeta_bygeom with np.nan before converting it to mm/day.
  • Fix an inconsistency issue with CRS projection when using UTM in nlcd_*. Use EPSG:3857 for all reprojections and get the data from NLCD in the same projection. (:issue_hydro:`85`)
  • Improve performance of nlcd_* functions by reducing number of service calls.

Internal Changes

  • Add type checking with typeguard and fix type hinting issues raised by typeguard.
  • Refactor show_versions to ensure getting correct versions of all dependencies.

0.12.2 (2021-12-31)

New Features

  • The NWIS.get_info now returns a geopandas.GeoDataFrame instead of a pandas.DataFrame.

Bug Fixes

  • Fix a bug in NWIS.get_streamflow where the drainage area might not be computed correctly if target stations are not located at the outlet of their watersheds.

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.

Bug Fixes

  • Fix an in issue with NWIS.get_streamflow where time zone of the data was not being correctly determined when it was US specific abbreviations such as CST.

0.12.0 (2021-12-27)

New Features

  • Add support for getting instantaneous streamflow from NWIS in addition to the daily streamflow by adding freq argument to NWIS.get_streamflow that can be either iv or dv. The default is dv to retain the previous behavior of the function.
  • Convert the time zone of the streamflow data to UTC.
  • Add attributes of the requested stations as attrs parameter to the returned pandas.DataFrame. (:issue_hydro:`75`)
  • Add a new flag to NWIS.get_streamflow for returning the streamflow as xarray.Dataset. This dataset has two dimensions; time and station_id. It has ten variables which includes discharge and nine other station attributes. (:issue_hydro:`75`)
  • Add drain_sqkm from GagesII to NWIS.get_info.
  • Show drain_sqkm in the interactive map generated by interactive_map.
  • Add two new functions for getting NLCD data; nlcd_bygeom and nlcd_bycoords. The new nlcd_bycoords function returns a geopandas.GeoDataFrame with the NLCD layers as columns and input coordinates, which should be a list of (lon, lat) tuples, as the geometry column. Moreover, The new nlcd_bygeom function now accepts a geopandas.GeoDataFrame as the input. In this case, it returns a dict with keys as indices of the input geopandas.GeoDataFrame. (:issue_hydro:`80`)
  • The previous nlcd function is being deprecated. For now, it calls nlcd_bygeom internally and retains the old behavior. This function will be removed in future versions.

Breaking Changes

  • The ssebop_byloc is being deprecated and replaced by ssebop_bycoords. The new function accepts a pandas.DataFrame as input that should include three columns: id, x, and y. It returns a xarray.Dataset with two dimensions: time and location_id. The id columns from the input is used as the location_id dimension. The ssebop_byloc function still retains the old behavior and will be removed in future versions.
  • Set the request caching's expiration time to never expire. Add two flags to all functions to control the caching: expire_after and disable_caching.
  • Replace NID class with the new RESTful-based web service of National Inventory of Dams. The new NID service is very different from the old one, so this is considered a breaking change.

Internal Changes

  • Improve exception handling in NWIS.get_info when NWIS returns an error message rather than 500s web service error.
  • The NWIS.get_streamflow function now checks if the site info dataset contains any duplicates. Therefore, all the remaining station numbers will be unique. This prevents an issue with setting attrs where duplicate indexes cause an exception when being converted to a dict. (:issue_hydro:`75`)
  • Add all the missing types so mypy --strict passes.

0.11.4 (2021-11-24)

New Features

  • Add support for the Water Quality Portal Web Services. (:issue_hydro:`72`)
  • Add support for two versions of NID web service. The original NID web service is considered version 2 and the new NID is considered version 3. You can pass the version number to the NID like so NID(2). The default version is 2.

Bug Fixes

  • Fix an issue with background percentage calculation in cover_statistics.

0.11.3 (2021-11-12)

New Features

  • Add a new map service for National Inventory of Dams (NID).

Internal Changes

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

0.11.2 (2021-07-31)

Bug Fixes

  • Refactor cover_statistics to address an issue with wrong category names and also improve performance for large datasets by using numpy's functions.
  • Fix an issue with detecting wrong number of stations in NWIS.get_streamflow. Also, improve filtering stations that their start/end date don't match the user requested interval.

0.11.1 (2021-07-31)

The highlight of this release is adding support for NLCD 2019 and significant improvements in NWIS support.

New Features

  • Add support for the recently released version of NLCD (2019), including the impervious descriptor layer. Highlights of the new database are:

    NLCD 2019 now offers land cover for years 2001, 2004, 2006, 2008, 2011, 2013, 2016, 2019, and impervious surface and impervious descriptor products now updated to match each date of land cover. These products update all previously released versions of land cover and impervious products for CONUS (NLCD 2001, NLCD 2006, NLCD 2011, NLCD 2016) and are not directly comparable to previous products. NLCD 2019 land cover and impervious surface product versions of previous dates must be downloaded for proper comparison. NLCD 2019 also offers an impervious surface descriptor product that identifies the type of each impervious surface pixel. This product identifies types of roads, wind tower sites, building locations, and energy production sites to allow deeper analysis of developed features.

    —MRLC

  • Add support for all the supported regions of NLCD database (CONUS, AK, HI, and PR).

  • Add support for passing multiple years to the NLCD function, like so {"cover": [2016, 2019]}.

  • Add plot.descriptor_legends function to plot the legend for the impervious descriptor layer.

  • New features in NWIS class are:

    • Remove query_* methods since it's not convenient to pass them directly as a dictionary.
    • Add a new function called get_parameter_codes to query parameters and get information about them.
    • To decrease complexity of get_streamflow method add a new private function to handle some tasks.
    • For handling more of NWIS's services make retrieve_rdb more general.

  • Add a new argument called nwis_kwds to interactive_map so any NWIS specific keywords can be passed for filtering stations.

  • Improve exception handling in get_info method and simplify and improve its performance for getting HCDN.

Internal Changes

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

0.11.0 (2021-06-19)

Breaking Changes

  • Drop support for Python 3.6 since many of the dependencies such as xarray and pandas have done so.
  • Remove get_nid and get_nid_codes functions since NID now has a ArcGISRESTFul service.

New Features

  • Add a new class called NID for accessing the recently released National Inventory of Dams web service. This service is based on ArcGIS's RESTful service. So now the user just need to instantiate the class like so NID() and with three methods of AGRBase class, the user can retrieve the data. These methods are: bygeom, byids, and bysql. Moreover, it has a attrs property that includes descriptions of the database fields with their units.
  • Refactor NWIS.get_info to be more generic by accepting any valid queries that are documented at USGS Site Web Service.
  • Allow for passing a list of queries to NWIS.get_info and use async_retriever that significantly improves the network response time.
  • Add two new flags to interactive_map for limiting the stations to those with daily values (dv=True) and/or instantaneous values (iv=True). This function now includes a link to stations webpage on USGS website.

Internal Changes

  • Use persistent caching for all send/receive requests that can significantly improve the network response time.
  • Explicitly include all the hard dependencies in setup.cfg.
  • Refactor interactive_map and NWIS.get_info to make them more efficient and reduce their code complexity.

Bug Fixes

  • Fixed an issue with the nlcd function where none layers are not dropped and cause the function to fails.

0.7.0 (2020-8-12)

This version divides PyGeoHydro into six standalone Python libraries. So many of the changes listed below belong to the modules and functions that are now a separate package. This decision was made for reducing the complexity of the code base and allow the users to only install the packages that they need without having to install all the PyGeoHydro dependencies.

Breaking changes

  • The services module is now a separate package called PyGeoOGCC and is set as a requirement for PyGeoHydro. PyGeoOGC is a leaner package with much fewer dependencies and is suitable for people who might only need an interface to web services.
  • Unified function names for getting feature by ID and by box.
  • Combined start and end arguments into a tuple argument called dates across the code base.
  • Rewrote NLDI function and moved most of its classmethods to Station so now Station class has more cohesion.
  • Removed exploratory functionality of ArcGISREST, since it's more convenient to do so from a browser. Now, base_url is a required argument.
  • Renamed in_crs in datasets and services functions to geo_crs for geometry and box_crs for bounding box inputs.
  • Re-wrote the signatures function from scratch using NamedTuple to improve readability and efficiency. Now, the daily argument should be just a pandas.DataFrame or pandas.Series and the column names are used for legends.
  • Removed utils.geom_mask function and replaced it with rasterio.mask.mask.
  • Removed width as an input in functions with raster output since resolution is almost always the preferred way to request for data. This change made the code more readable.
  • Renamed two functions: ArcGISRESTful and wms_bybox. These function now return requests.Response type output.
  • onlyipv4 is now a class method in RetrySession.
  • The plot.signatures function now assumes that the input time series are in mm/day.
  • Added a flag to get_streamflow function in the NWIS class to convert from cms to mm/day which is useful for plotting hydrologic signatures using the signatures functions.

Enhancements

  • Remove soft requirements from the env files.
  • Refactored requests functions into a single class and a separate file.
  • Made all the classes available directly from PyGeoHydro.
  • Added CodeFactor to the Github pipeline and addressed some issues that CodeFactor found.
  • Added Bandit to check the code for security issue.
  • Improved docstrings and documentations.
  • Added customized exceptions for better exception handling.
  • Added pytest fixtures to improve the tests speed.
  • Refactored daymet and nwis_siteinfo functions to reduce code complexity and improve readability.
  • Major refactoring of the code base while adding type hinting.
  • The input geometry (or bounding box) can be provided in any projection and the necessary re-projections are done under the hood.
  • Refactored the method for getting object IDs in ArcGISREST class to improve robustness and efficiency.
  • Refactored Daymet class to improve readability.
  • Add Deepsource for further code quality checking.
  • Automatic handling of large WMS requests (more than 8 million pixels i.e., width x height)
  • The json_togeodf function now accepts both a single (Geo)JSON or a list of them
  • Refactored plot.signatures using add_gridspec for a much cleaner code.

New Features

  • Added access to WaterData's GeoServer databases.
  • Added access to the remaining NLDI database (Water Quality Portal and Water Data Exchange).
  • Created a Binder for launching a computing environment on the cloud and testing PyGeoHydro.
  • Added a URL repository for the supported services called ServiceURL
  • Added support for FEMA web services for flood maps and FWS for wetlands.
  • Added a new function called wms_toxarray for converting WMS request responses to xarray.DataArray or xarray.Dataset.

Bug Fixes

  • Re-projection issues for function with input geometry.
  • Start and end variables not being initialized when coords was used in Station.
  • Geometry mask for xarray.DataArray
  • WMS output re-projections
