Changelog

All notable changes to this project will be documented in this file.

[0.7.3] - 2026-03-07

Added

  • Added methods depression_depth, depression_volume, drainage_potential and percentile_elevation.
  • Added FlowDirection that wraps integer encodings for flow direction.

Fixed

  • No more double flow accumulation on edges (cells without flow direction)

Changed

  • The second returned argument ldd of flowaccumulation now returns a Matrix{Direction{C, UInt8}} instead of a Matrix{UInt8}.
  • The second returned argument ldd of flowaccumulation now return multiple flow direction encodings (LDD) when DInf() and FD8 are used for the method kwarg. These range from 0 to 128, not just 1-9.
  • Changed default method for all flow related methods from D8() to DInf().

Deprecated

  • All shorthand names (e.g. TPI, HAND) are now deprecated in favour of their written out names (e.g. topographic_position_index).

[0.7.2] - 2026-03-03

Added

  • Added horizon_angle and sky_view_factor methods.

[0.7.1] - 2025-09-03

Fixed

  • Fixed incorrect flows of DInf and FD8 methods

[0.7.0] - 2025-03-21

Added

  • Improved documentation by using VitePress and showcasing all methods on a DEM.
  • Added hydrology operators: priorityflood, streamflow
  • Added multiscale options to some filters using a window kwarg for a Stencil from Stencils.jl package. Other methods now take a radius kwarg.
  • Added BPI
  • Overhauled curvature methods by introducing plan_curvature, profile_curvature and contour_curvature, while deprecating curvature for laplacian
  • Added direction kwarg to slope and curvature methods.
  • Added this CHANGELOG.md
  • Added package extensions on GeoArrays, Rasters to support automatic cellsizes.
  • Added package extension on Eikonal for a faster spread method.

Changed

  • Added Stencils as dependency.
  • Refactored spread to choose from multiple algorithms

Fixed

  • Relaxed Array input to AbstractArray for opening

[0.6.0] - 2023-08-25

Changed

  • Renamed package to Geomorphometry

Added

  • Added erosion parameter in PMF

[0.5.2] - 2023-08-14

Changed

  • Light maintenance to CI scripts
  • Compat updates

[0.5.1] - 2023-01-12

Added

  • Relaxed input for PMF

[0.5.0] - 2022-11-02

Added

  • Added multihillshade

Changed

  • Uses LocalFilters for terrain filters, improving performance, but changing the edge behaviour of some filters.

[0.4.0] - 2022-10-17

Added

  • Added hillshade, curvature

Changed

  • Used LocalFilters for PMF.

[0.3.2] - 2022-09-07

Added

  • Added terrain kernels for different algorithms.

Fixed

  • Fixed bug in TPI

[0.3.1] - 2022-06-15

Added

  • Added skewness filter

[0.3.0] - 2022-02-01

Added

  • Added PSF (Progressive Slope Filter) function.

Changed

  • Improved performance of mapwindow function used in most filters.

[0.2.0] - 2021-11-22

Added

  • Initial release of the GeoArrayOps package.
  • Basic terrain analysis functions.
