Release Notes

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.

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.
