Bug fixes:

  • Return the correct coordinates when passing pixel_register=True and shape to verde.grid_coordinates. The returned coordinates had 1 too few elements in each dimension (and the wrong values). This is because we generate grid-line registered points first and then shift them to the center of the pixels and drop the last point. This only works when specifying spacing because it will generate the right amount of points. When shape is given, we need to first convert it to “grid-line” shape (with 1 extra point per dimension) before generating coordinates. (#183)
  • Reset force coordinates when refitting splines. Previously, the splines set the force coordinates from the data coordinates only the first time fit was called. This means that when fitting on different data, the spline would still use the old coordinates leading to a poor prediction score. Now, the spline will use the coordinates of the current data passed to fit. This only affects cases where force_coords=None. It’s a slight change and only affects some of the scores for cross-validation. (#191)

New functions/classes:

  • New class verde.SplineCV: a cross-validated version of Spline . that performs grid search cross-validation to automatically tune the parameters of a Spline. (#185)
  • New function verde.longitude_continuity to format longitudes to a continuous range so that they can be indexed with verde.inside (#181)
  • New function verde.load_surfer to load grid data from a Surfer ASCII file (a contouring, griding and surface mapping software from GoldenSoftware). (#169)
  • New function verde.median_distance that calculates the median near neighbor distance between each point in the given dataset. (#163)

Improvements:

  • Allow verde.block_split and verde.BlockReduce to take a shape argument instead of spacing. Useful when the size of the block is less meaningful than the number of blocks. (#184)
  • Allow zero degree polynomials in verde.Trend, which represents a mean value. (#162)
  • Function verde.cross_val_score returns a numpy array instead of a list for easier computations on the results. (#160)
  • Function verde.maxabs now handles inputs with NaNs automatically. (#158)

Documentation:

  • New tutorial to explain the intricacies of grid coordinates generation, adjusting spacing vs region, pixel registration, etc. (#192)

Maintenance:

  • Drop support for Python 3.5. (#178)
  • Add support for Python 3.7. (#150)
  • More functions are now part of the base API: n_1d_arrays, check_fit_input and least_squares are now included in verde.base. (#156)
