  • fixed legend in plot_landscape and added legend_kws arg
  • fixed multilandscape plot with one landscape, e.g., 1-zone analysis
  • fixed values of zone_arr (to id zones) to avoid nodata=0 confusion
  • default nodata (when providing numpy arrays) from settings module

2.2.1 (12/11/2020)

  • ZonalAnalysis.attribute_name from masks when providing geoseries
  • avoid reprojecting equivalent CRS (pyproj __eq__ vs. is_exact_same) in ZonalAnalysis

2.2.0 (05/11/2020)

  • fill NaN values according to the metric in MultiLandscape.compute_class_metrics_df
  • consistent imports so that there are no direct class/function calls, and no module abbreviations in the documentation
  • zonal analysis with more general masks argument, which also accepts vector geometries (and replaces the now deprecated masks_arr)

2.1.3 (02/09/2020)

  • ensure numeric dtypes in metrics data frames
  • np.nan nodata in img passed to rasterio.plot.show in plot_landscape

2.1.2 (03/08/2020)

  • more robust loc (with index and columns) to compute metrics data frames in MultiLandscape

2.1.1 (12/06/2020)

  • corrected ZonalGridAnalysis docstring
  • corrected computation of num_zone_cols in ZonalGridAnalysis

2.1.0 (11/05/2020)

  • added compute_zonal_statistics method to ZonalAnalysis and aded ZonalGridAnalysis class
  • Implemented the effective_mesh_size metric

2.0.0a1 (24/09/2019)

  • gradient -> zonal

  • updates in the docs (changed link to notebook + cleaned Makefile)

2.0.0a0 (20/09/2019)

  • corrected shapely version in setup.py (bumpversion messed it)

1.1.1 (18/09/2019)

  • corrected rst typo in total_area docs
  • fixed missing perimeter distribution statistic metric and dried class constants definitions

1.1.0 (17/09/2019)

  • speed-up (~x2) in Landscape.compute_patch_euclidean_nearest_neighbor: compute pixel-to-pixel distances for patch edges only

  • fix landscape array dtype in GradientAnalysis and BufferAnalysis

1.0.0 (18/07/2019)

  • added SpatioTemporalBufferAnalysis.plot_landscapes method
  • added buffer_dist_legend argument and docs in SpatioTemporalBufferAnalysis. plot_metric
  • fix proper metric data frame properties in SpatioTemporalBufferAnalysis

  • changed feature_{name,values} for attribute_{name,values} in MultiLandscape (abstract) class
  • dropped plot_metrics method

0.6.1 (02/07/2019)

  • cell width and length comparisons with numpy.isclose to deal with imprecisions that come from float pixel resolutions (e.g., in GeoTIFF files)
  • critical fix: moved pythran signatures from compute.pythran to compute.py so that the build is properly done when pip-installing

0.6.0 (01/07/2019)

  • flat array approach to the computation of the adjacency matrix with pythran to improve performance (plus fixes a bug on the computation of total_edge)
  • initialization of scipy.spatial.cKDTree with keyword arguments balanced_tree and compact_nodes set to False

0.5.0 (28/05/2019)

  • methods plotting multiple axes return only the figure instead of a tuple with the figure and the axes

  • chaged CRS in tests to work with pyproj >= 2.0.0
  • corrected figlength for figwidth
