History#

0.18.1 (2024-XX-XX)#

New Features#

  • Add a function called sample_window to remsample a raster dataset using a window size and a rasterio supported resampling method. This is an efficient way of sampling large raster datasets without reading the entire dataset into memory. The function returns a generator that yields the sampled values in the order of the input coordinates. This function is based on the rasterio.sample.sample_gen function.

0.18.0 (2024-10-05)#

New Features#

  • Add a function called achored_amoothin``to smooth a ``LineString using Cubnic splines that anchores the first and last points of the LineString.

  • Add a function called smooth_multilinestring to smooth a MultiLineString using the new anchored_smoothin function.

  • In line_curvature use spline_curvature to calculate the curvature of a LineString at all points along the LineString. This is more accurate than the previous method and users can now specify the smoothing factor (s) and degree of the spline (k) to control the smoothness of the spline that is used to calculate the curvature.

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.

Internal Changes#

  • Move all spline and smoothing functions to a new module called smoothing.

0.17.1 (2024-09-14)#

Internal Changes#

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

0.16.3 (2024-05-16)#

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.

  • Improve robustness of json2geodf by ensuring that all geojsons are in the same CRS.

0.16.1 (2024-01-15)#

Bug Fixes#

  • pyproj uses its own env variables for SSL certification. This release fixes the issue with pyproj not being able to download the grid database when using DOI SSL certification file. This release uses pyproj.network.set_ca_bundle_path for setting the SSL certification file given by the user via HYRIVER_SSL_CERT env variable.

  • Ignore FutureWarning of pandas 2.1.0 for all-NaN columns in json2geodf.

Internal Changes#

  • For Attrs class, use dataclass instead for better performance and consistency.

0.16.0 (2024-01-03)#

Breaking Changes#

  • Refactor the spline generation functions to make them more efficient, more accurate, and more robust. Switched to using UnivariateSpline from scipy instead of BSpline. This allows for more control over smoothness of the spline via the smooth parameter. References to BSpline has been removed from the functions and a new functionality has been added. The new spline generation functions are GeoSpline, make_spline, spline_linestring, smooth_linestring, spline_curvature, and line_curvature. The smooth_linestring function now returns a LineString instead of a Spline object. This function is intended for smoothing a LineString when curvature, radius of curvature, and tangent angles are not needed. The spline_linestring function now returns a Spline object that contains the smoothed LineString and curvature, radius of curvature, and tangent angles. Also, line_curvature function can be used to compute curvature, radius of curvature, and tangent angles of a LineString at all point along the LineString.

New Features#

  • Add a new function called gtiff2vrt for creating a VRT file from a list of GeoTiff files. Note that this new function requires gdal to be installed.

  • The xd_write_crs function now keeps spatial_ref attribute of the input xarray.DataArray or xarray.Dataset to retain CF compliance.

0.15.2 (2023-09-22)#

New Features#

  • Add geometry_reproject function for reprojecting a geometry (bounding box, list of coordinates, or any shapely.geometry) to a new CRS.

  • Add smooth_linestring function for smoothing a LineString using B-splines.

  • Make make_bspline and bspline_curvature functions public. The make_bspline function uses scipy to generate a BSplines object and the bspline_curvature function calculates the tangent angles, curvature, and radius of curvature of a B-spline at any point along the B-spline.

  • Improve the accuracy and performance of B-spline generation functions.

Internal Changes#

  • Remove dependency on dask.

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#

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

0.14.0 (2023-03-05)#

New Features#

  • Ignore index when concatenating multiple responses in json2geodf to ensure indices are unique

  • Add a new function, called coords_list, for converting/validating input coordinates of any type to a list of tuple, i.e., [(x1, y1), (x2, y2), ...].

  • Make xd_write_crs function public.

  • In xarray_geomask if the input geometry is very small return at least one pixel.

  • Add a new function, called multi2poly, for converting a MultiPolygon to a Polygon in a GeoDataFrame. This function tries to convert MultiPolygon to Polygon by first checking if MultiPolygon can be directly converted using their exterior boundaries. If not, will try to remove those small sub-Polygon that their area is less than 1% of the total area of the MultiPolygon. If this fails, the original MultiPolygon will be returned.

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 (2023-02-10)#

Breaking Changes#

  • The input GeoDataFrame to break_lines now should be in a projected CRS.

New Features#

  • Significant improvements in the accuracy and performance of nested_``Polygon`` by changing the logic. Now, the function first determines the nested Polygon by comparing the centroids of the geometries with their geometry and then picks the largest geometry from each group of nested geometries.

  • Add a new function called query_indicies which is a wrapper around geopandas.sindex.query_bulk. However, instead of returning an array of positional indices, it returns a dictionary of indices where keys are the indices of the input geometry and values are a list of indices of the tree geometries that intersect with the input geometry.

Internal Changes#

  • Simplify geo2polygon by making the two CRS arguments optional and only reproject if CRS values are given and different.

  • Apply the geometry mask in gtiff2xarray even if the input geometry is a bounding box since the mask might not be the same geometry as the one that was used during data query.

  • 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.

0.13.11 (2023-01-08)#

Bug Fixes#

  • Fix an in issue xarray_geomask where for geometries that are smaller than a single pixel, the bbox clipping operation fails. This is fixed by using the auto_expand option of rioxarray.clip_box.

0.13.10 (2022-12-09)#

New Features#

  • Add a new function called nested_``Polygon`` for determining nested (multi)``Polygon`` in a gepandas.GeoDataFrame or geopandas.GeoSeries.

  • Add a new function called geodf2xarray for rasterizing a geopandas.GeoDataFrame to a xarray.DataArray.

Internal Changes#

  • Modify the codebase based on Refurb suggestions.

  • In xarray_geomask, if drop=True recalculate its transform to ensure the correct geo references are set if the shape of the dataset changes.

0.13.8 (2022-11-04)#

Internal Changes#

  • Improve the performance of xarray_geomask significantly by first clipping the data to the geometry’s bounding box, then if the geometry is a polygon, masking the data with the polygon. This is much faster than directly masking the data with the polygon. Also, support passing a bounding box to xarray_geomask in addition to polygon and MultiPolygon.

  • Fix deprecation warning of pandas when changing the geometry column of a GeoDataFrame in then break_lines function.

0.13.7 (2022-11-04)#

Internal Changes#

  • When combining the responses, now dask handles data chunking more efficiently. This is especially important for handling large responses from WMS services.

  • Improve type hints for CRS-related arguments of all functions by including string, integer, and pyproj.CRS types.

  • In gtiff2xarray use rasterio engine to make sure all rioxarray attrs are read.

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.

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.

  • Bump min versions of rioxarray to 0.10 since it adds reading/writing GCPs.

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 passing a custom bounding box in the Coordinates class. The default is the bounds of EPSG:4326 to retain backward compatibility. This new class parameter allows a user to check if a list of coordinates is within a custom bounding box. The bounds should be the EPSG:4326 coordinate system.

  • Add a new function called geometry_list for converting a list of multi-geometries to a list of geometries.

0.13.0 (2022-03-03)#

Internal Changes#

  • Write nodata attribute using rioxarray in geotiff2xarray since the clipping operation of rioxarray uses this value as fill value.

Bug Fixes#

  • In the break_lines function, convert MultiLineString into LineString since shapely.ops.substring only accepts LineString.

0.12.3 (2022-02-04)#

New Features#

  • Add a function called break_lines for breaking lines at given points.

  • Add a function called snap2nearest for snapping points to the nearest point on a line with a given tolerance. It accepts a geopandas.GeoSeries of points and a geopandas.GeoSeries or geopandas.GeoDataFrame of lines. It automatically snaps to the closest lines in the input data.

0.12.2 (2022-01-15)#

New Features#

  • Add a new class called GeoBSpline that generates B-splines from a set of coordinates. The spline attribute of this class has five attributes: x and y coordinates, phi and radius which are curvature and radius of curvature, respectively, and distance which is the total distance of each point along the B-spline from the starting points.

  • Add a new class called Coordinates that validates a set of lon/lat coordinates. It normalizes longitudes to the range [-180, 180) and has a points property that is geopandas.GeoSeries with validated coordinates. It uses spatial indexing to speed up the validation and should be able to handle large datasets efficiently.

  • Make transform2tuple a public function.

Internal Changes#

  • The geometry and geo_crs arguments of gtiff2xarray are now optional. This is useful for cases when the input GeoTiff response is the results of a bounding box query and there is no need for a geometry mask.

  • Replace the missing values after adding geometry mask via xarray_geomask by the nodatavals attribute of the input xarray.DataArray or xarray.Dataset. Therefore, the data type of the input xarray.DataArray or xarray.Dataset is conserved.

  • Expose connectivity argument of rasterio.features.shapes function in xarray2geodf function.

  • Move all private functions to a new module to make the main module less cluttered.

0.12.1 (2021-12-31)#

Internal Changes#

  • Refactor arcgis2geojson for better readability and maintainability.

  • In arcgis2geojson set the geometry to null if its type is not supported, such as curved polylines.

0.12.0 (2021-12-27)#

Internal Changes#

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

  • Bump version to 0.12.0 to match the release of pygeoogc.

0.11.7 (2021-11-09)#

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.

0.11.6 (2021-10-06)#

New Features#

  • Add a new function, xarray2geodf, to convert a xarray.DataArray to a geopandas.GeoDataFrame.

0.11.5 (2021-06-16)#

Bug Fixes#

  • Fix an issue with gtiff2xarray where the scales and offsets attributes of the output DataArray were floats rather than tuples (GH 30).

Internal Changes#

  • Add a new function, transform2tuple, for converting Affine transforms to a tuple. Previously, the Affine transform was converted to a tuple using to_gdal() method of rasterio.Affine which was not compatible with rioxarray.

0.11.4 (2021-08-26)#

Internal Changes#

  • Use ujson for JSON parsing instead of orjson since orjson only serializes to bytes which is not compatible with aiohttp.

  • Convert the transform attribute data type from Affine to tuple since saving a data array to netcdf cannot handle the Affine type.

0.11.3 (2021-08-19)#

  • Fix an issue in geotiff2xarray related to saving a xarray object to NetCDF when its transform attribute has Affine type rather than a tuple.

0.11.2 (2021-07-31)#

The highlight of this release is performance improvement in gtiff2xarray for handling large responses.

New Features#

  • Automatic detection of the driver by default in gtiff2xarray as opposed to it being GTiff.

Internal Changes#

  • Make geo2polygon, get_transform, and get_nodata_crs public functions since other packages use it.

  • Make xarray_mask a public function and simplify gtiff2xarray.

  • Remove MatchCRS since it’s already available in pygeoogc.

  • Validate input geometry in geo2polygon.

  • Refactor gtiff2xarray to check for the ds_dims outside the main loops to improve the performance. Also, the function tries to detect the dimension names automatically if ds_dims is not provided by the user, explicitly.

  • Improve performance of json2geodf by using list comprehension and performing checks outside the main loop.

Bug Fixes#

  • Add the missing arguments for masking the data in gtiff2xarray.

0.11.1 (2021-06-19)#

Bug Fixes#

  • In some edge cases the y-coordinates of a response might not be monotonically sorted so dask fails. This release sorts them to address this issue.

0.11.0 (2021-06-19)#

New Features#

  • Function gtiff2xarray returns a parallelized xarray.Dataset or xarray.DataAraay that can handle large responses much more efficiently. This is achieved using dask.

Breaking Changes#

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

  • Refactor MatchCRS. Now, it should be instantiated by providing the in and out CRSs like so: MatchCRS(in_crs, out_crs). Then its methods, namely, geometry, bounds and coords, can be called. These methods now have only one input, geometry.

  • Change input and output types of MatchCRS.coords from tuple of lists of coordinates to list of (x, y) coordinates.

  • Remove xarray_mask and gtiff2file since rioxarray is more general and suitable.

Internal Changes#

  • Remove unnecessary type checks for private functions.

  • Refactor json2geodf to improve robustness. Use get method of dict for checking key availability.

0.10.1 (2021-03-27)#

  • Setting transform of the merged dataset explicitly (GH 3).

  • 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.

  • Address GH 1 by sorting y coordinate after merge.

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

  • Speed up CI testing by using mamba and caching.

  • Add gtiff2file for saving raster responses as geotiff file(s).

  • Fix an error in _get_nodata_crs for handling no data value when its value in the source is None.

  • Fix the warning during the GeoDataFrame generation in json2geodf when there is no geometry column in the input JSON.

0.2.0 (2020-12-06)#

  • Added checking the validity of input arguments in gtiff2xarray function and provide useful messages for debugging.

  • Add support for MultiPolygon.

  • Remove the fill_hole argument.

  • Fixed a bug in xarray_geomask for getting the transform.

0.1.10 (2020-08-18)#

  • Add MatchCRS class.

  • Remove dependency on PyGeoOGC.

  • Increase test coverage.

0.1.3 (2020-07-21)#

  • Remove duplicate rows before returning the dataframe in the json2geodf function.

  • Add the missing dependency

0.1.0 (2020-07-21)#
