[0.6.2] - 2019-02-19

We have made significant changes in preparation for a 1.0 release on PyPI. If you have used EarthPy previously, please review the changes below. You may need to update your code accordingly.

Changed

  • normalized_diff() function arguments have been flipped. Please update all of your old code accordingly. Changes include:
    • Arguments are now provided as normalized_diff(b1, b2)
    • Math will be calculated (b1-b2) / (b1+b2)
    • Example: ndvi = es.normalized_diff(b1=nir_band, b2=red_band)
  • normalized_diff() now:
    • returns unmasked array by default
    • returns masked array if there are nan values present
    • converts infinity values that result from division by zero to nan values
  • stack() replaces stack_raster_tifs(), which is now deprecated. The new stack() function works similarly to stack_raster_tifs. Inputs parameters are now a list of filepaths and an optional filepath parameter that when populated saves the stacked raster array as a geotiff file. The default return is a numpy ndarray.
  • The parameter order for bytescale has changed:
    • PREVIOUS ORDER: data, cmin=None, cmax=None, high=255, low=0
    • NEW ORDER: data, high=255, low=0, cmin=None, cmax=None
  • All plot functions moved to a new earthpy.plot module. To import plot functions first import the plot module: import earthpy.plot as ep. Then you can call functions as follows:
    • ep.plot_rgb()
    • ep.draw_legend()
    • ep.hist()
    • ep.colorbar()
    • ep.plot_bands()

Added

  • draw_legend() works now on different types of categorical raster plots.
  • colorbar() has also been fixed to work given updates to Matplotlib
  • A new mask function has been released as mask_pixels().
  • We now have tests through pytest that run on Travis CI.
  • API documentation is now generated automatically from docstrings with autodoc.
  • Example code in documentation is tested using doctest

Deprecated

  • stack_raster_tifs() has been deprecated and replaced with stack().
