History#

0.18.0 (2024-10-05)#

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#

  • A release without change to match the version of other HyRiver packages.

0.17.0 (2024-05-07)#

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.

0.16.3 (2024-04-24)#

Bug Fixes#

  • In check_3dep_availability function, fix a bug where the function fails to return a valid response when the web service is down.

0.16.2 (2024-02-12)#

Bug Fixes#

  • In add_elvation function, fix a bug where the function fails to add elevation to a xarray.Dataset with x and y dims not being x and y.

Internal Changes#

  • Refactor fill_depressions function by porting the code from pyflwdir and improve its performance and also now, it directly support xarray.DataArray. Now, pyflwdir is not an optional dependency anymore. You can install numba to improve the performance of the function.

Breaking Changes#

  • The AirMap service has been deprecated and removed from the package. The elevation_bycoords function now only supports the the National Map and the 3DEP services.

0.16.1 (2024-01-15)#

Bug Fixes#

  • In the check_3dep_availability function when the web service is down the function raises a TypeError instead of setting the value of the failed resolution to Failed. This is fixed now. (GH 66).

Internal Changes#

  • Simplify the logic of adding elevation to a Dataset in the add_elevation function to avoid modifying CRS of the input Dataset.

0.16.0 (2024-01-03)#

New Features#

  • Add a new function called get_map_vrt for getting DEM within a bounding box and saving it as a VRT file. This function has low memory usage and is useful for cases where the DEM is needed for a large area. Moreover, even for usual use cases it can be much faster than get_dem since it loads the data lazily, at the cost of higher disk usage.

  • In the get_map function, check if the input geometry is within the bounds of the 3DEP’s WMS service and if not, raise an exception.

  • In the fill_depressions function add a new argument called outlets for specifying outlet detection method: At the edge of all cells (edge) or only the minimum elevation edge cell (min; default).

  • Significantly improve the performance of check_3dep_availability function by minimizng the number of requests to the service and sending all requests asynchronously. Also, the returned dict now uses Failed for those resolutions where the service fails to return a valid response. It will remove the failed responses from the cache, so next time the function is called, it will try to get only the failed resolutions.

  • Add four new options to add_elevation: mask for passing a mask and resolution for specifying the resolution of the source DEM, and x_dim and y_dim for passing the names of spatial dimensions in the input dataset. The mask option is useful for cases where the input xarray.DataArray or xarray.Dataset has a mask and the user wants to use that mask for the elevation data as well. The resolution option is useful for cases where the user wants to get the elevation data at a higher resolution that will be downsampled by bilinear interpolation to the resolution of the input xarray.DataArray or xarray.Dataset. The default is resolution=None which means the resolution of the input xarray.DataArray or xarray.Dataset will be used. The x_dim and y_dim options are useful for cases where the input xarray.DataArray or xarray.Dataset has different names for spatial dimensions than x and y. The default is x_dim="x" and y_dim="y".

Breaking Changes#

  • In the elevation_profile function remove the res argument and use 10-m resolution DEM from 3DEP. Also, add two new attributes to the output xarray.Dataset: source for the dataset to state the data source used and units for the distance variable to state the units of the distance, which is meters.

Internal Changes#

  • Improve initial load time by moving import pyflwdir to the fill_depressions function.

Bug Fixes#

  • Decrease the number of pixels per request from 10e6 to 8e6 to reduce the request load (GH 65).

0.15.2 (2023-09-22)#

Internal Changes#

  • Remove dependency on dask.

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#

  • In static_3dep_dem use rioxarray directly instead of rasterio since it can handle VRT files.

  • Improve performance and accuracy of add_elevation by using the dynamic 3DEP service and setting the resolution based on the input xarray.DataArray or xarray.Dataset.

  • Improve the performance of elevation_profile by using the static 3DEP service when the input resolution is 10 m (which is the default for this function).

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

Bug Fixes#

  • In add_elevation, ensure that the resolution is in meters by reprojecting the input dataset to 5070 before extracting resolution and bound attributes.

0.14.0 (2023-03-05)#

New Features#

  • Add a new function called add_elevation for adding elevation data as a new variable to an input xarray.DataArray or xarray.Dataset.

  • The elevation_bycoords function now accepts a single coordinate and returns a float in addition to a list of coordinates that returned a list of elevations.

  • Modify the elevation_bycoords function to use the new elevation point query service (EPQS) web service. This only affects the source="tnm" option.

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.

0.13.12 (2023-02-01)#

New Features#

  • Use pyflwdir package for depression filling operation instead of richdem since it appears to be unmaintained. Note that pyflwdir is an optional dependency. Also, pyflwdir depends on numba which is not available for Python 3.11 yet. You can follow the progress of numba’s support for Python 3.11 here.

  • Add a new function called get_dem for obtaining DEM that is a wrapper of static_3dep_dem and get_map functions. Since static_3dep_dem is faster, if the requested resolution is 10 m, 30 m, or 60 m, static_3dep_dem will be used. Otherwise, get_map will be used.

Internal Changes#

  • Significantly improve the performance of elevation_bycoords when tep is used as the source by using the static DEM data instead of the dynamic DEM.

  • 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 (2023-01-08)#

New Features#

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

Bug Fixes#

  • Fix a compatibility issue with the new scipy version in elevation_profile where led to failure of interpolation.

0.13.9 (2022-12-15)#

Bug Fixes#

  • Add the missing annotation import to the cache_keys to ensure Python 3.8 and 3.9 work with Python 3.10 style type hinting.

0.13.8 (2022-12-09)#

New Features#

  • Add a new function called static_3dep_dem for getting only DEM data at 10 m, 30, or 60 m resolution. This is useful for cases where only DEM data (i.e., not slope, aspect, or other terrain attributes that the Dynamic 3DEP service provides) is needed. This function is faster than get_map but is less flexible.

Internal Changes#

  • Modify the codebase based on Refurb suggestions.

0.13.7 (2022-11-04)#

Internal Changes#

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

  • Bump the minimum required version of HyRiver dependencies to the latest versions.

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#

  • Increase the pixel limit for 3DEP’s WMS from 8M to 10M to reduce number of service calls and improve performance.

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

0.13.3 (2022-06-25)#

Bug Fixes#

  • Fix a bug in check_3dep_availability where due to changes in pygeoogc ZeroMatched exception is raised instead of TypeError and as a result check_3dep_availability was not working as expected.

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#

  • In deg2mpm function look for _FillValue and nodatavals in the attributes and if not found, fall back to numpy.nan.

Internal Changes#

  • Ensure that the deg2mpm function uses dask if the input is dask-enabled.

  • In the elevation_profile function use a bounding box to get DEM and a linear interpolation to get the elevation along the profile.

0.13.0 (2022-04-03)#

New Features#

  • Add a new function called query_3dep_sources for querying bounds of 3DEP’s data sources within a bounding box. It returns a geo-dataframe that contains the bounding box of each data source and a column dem_res identifying the resolution of the raw topographic data within each geometry.

  • Add a new function called elevation_profile for getting elevation profile along a line at a given spacing. This function converts the line to a B-spline and then calculates the elevation along the spline at a given uniform spacing.

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 (2022-01-15)#

New Features#

  • Add a new DEM source to elevation_bycoords to get elevation from the National Map’s 3DEP WMS service. This can replace the tnm source since tnm is not stable.

  • Add a new function called check_3dep_availability to check the availability of 3DEP’s native resolutions within an area of interest. It returns a dict with keys corresponding to the available resolutions and its values are boolean values indicating whether the resolution is available or not.

  • Replace no data values of slope in deg2mm with np.nan, so they do not get converted to another value. The output of this function has np.float64 type.

Internal Changes#

  • Refactor ElevationByCoords by using __post_init__ for validating the input parameters rather than pydantic’s validators.

  • Refactor elevation_bygrid by using get_map to get DEM and rioxarray for re-projection.

  • Add type checking with typeguard and fixed typing issues raised by typeguard.

  • Refactor show_versions to ensure getting correct versions of all dependencies.

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.

0.12.0 (2021-12-27)#

Breaking Changes#

  • 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.

Internal Changes#

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

  • Improve performance of elevation_bygrid by ignoring unnecessary validation.

0.11.4 (2021-11-12)#

Internal Changes#

  • Use rioxarray for dealing with GeoTIFF binaries since xarray deprecated the xarray.open_rasterio function, as it’s discussed in this PR.

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

0.11.3 (2021-10-03)#

Breaking Changes#

  • Rewrite the command-line interface using click.group to improve UX. The command is now py3dep [command] [args] [options]. The two supported commands are coords for getting elevations of a dataframe of coordinates in EPSG:4326 CRS and geometry for getting the elevation of a geo-dataframe of geometries. Each sub-command now has a separate help message. The format of the input file for the coords command is now csv and for the geometry command is .shp or .gpkg and must have a crs attribute. Also, the geometry command now accepts multiple layers via the --layers (-l) option. More information and examples can be in the README.rst file.

New Features#

Internal Changes#

  • The get_map function now checks for validation of the input layers argument before sending the actual request with a more helpful message.

  • Improve docstrings.

  • Move deg2mpm, fill_depressions, and reproject_gtiff functions to a new file called utils. Both deg2mpm and fill_depressions functions are still accessible from py3dep directly.

  • Increase the test coverage.

  • Use one of the click’s internal functions, click..testing.CliRunner, to run the CLI tests.

0.11.2 (2021-09-17)#

Bug Fixes#

  • Fix a bug related to elevation_bycoords where CRS validation fails if its type is pyrpoj.CRS by converting inputs with CRS types to string.

Internal Changes#

  • Fix a couple of typing issues and update the get_transform API based on the recent changes in pygeoutils v0.11.5.

0.11.1 (2021-07-31)#

The first highlight of this release is a major refactor of elevation_bycoords by adding support for the Bulk Point Query Service and improving the overall performance of the function. Another highlight is support for performing depression filling in elevation_bygrid before sampling the underlying DEM.

New Features#

  • Refactor elevation_bycoords function to add support for getting elevations of a list of coordinates via The National Map’s Point Query Service. This service is more accurate than Airmap, but it’s limited to the US only. You can select the source via a new argument called source. You can set it to source=tnm to use the TNM service. The default is tnm.

  • Refactor elevation_bygrid function to add a new capability via fill_depressions argument for filling depressions in the obtained DEM before extracting elevation data for the input grid points. This is achieved via RichDEM that needs to be installed if this functionality is desired. You can install it via pip or conda (mamba).

Internal Changes#

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

  • Handle the interpolation step in elevation_bygrid function more efficiently using xarray.

0.11.0 (2021-06-19)#

New Features#

  • Added command-line interface (GH 10).

  • All feature query functions use persistent caching that can significantly improve the performance.

Breaking Changes#

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

  • The returned xarray objects are in parallel mode, i.e., in some cases compute method should be used to get the results.

  • Save the output as a netcdf instead of raster since conversion from nc to tiff can be easily done with rioxarray.

0.10.1 (2021-03-27)#

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

  • Improve pip installation and release workflow.

0.10.0 (2021-03-06)#

  • The first release after renaming hydrodata to PyGeoHydro.

  • 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.

  • Add support for saving maps as geotiff file(s).

  • Replace Elevation Point Query Service service with AirMap for getting elevations for a list of coordinates in bulk since AirMap is much faster. The resolution of AirMap is 30 m.

  • Use cytoolz for some operations for improving performance.

0.2.0 (2020-12-06)#

  • Add support for multipolygon.

  • Remove the fill_hole argument.

  • Add a new function to get elevations for a list of coordinates called elevation_bycoords.

  • Refactor elevation_bygrid function for increasing readability and performance.

0.1.7 (2020-08-18)#

  • Added a rename operation to get_map to automatically rename the variables to a more sensible one.

  • Replaced simplejson with orjson to speed-up JSON operations.

0.1.6 (2020-08-11)#

  • Add a new function, show_versions, for getting versions of the installed dependencies which is useful for debugging and reporting.

  • Fix typos in the docs and improved the README.

  • Improve testing and coverage.

0.1.5 (2020-08-03)#

  • Fixed the geometry CRS issue

  • Improved the documentation

0.1.4 (2020-07-23)#

  • Refactor get_map to use pygeoutils package.

  • Change the versioning method to setuptools_scm.

  • Polish README and add installation from conda-forge.

0.1.0 (2020-07-19)#

  • First release on PyPI.
