API Reference
Geomorphometry

Common operations

Defines common methods for analyzing, filtering and visualizing (global) elevation models. All methods are implemented in Julia and are fast and scalable.

Multiple algorithms

Choose from multiple algorithms, ranging from different derivations of slope to multiresolution stencils. This enables the user to select the most appropriate method for their use case.

Seamless integration

Geomorphometry.jl is fully compatible with the AbstractArray and GeoInterface.jl ecosystems. This enables plotting, operations and analysis using the full power of the Julia ecosystem.

Functionality ​

  • Terrain filters, such as Progressive Morphological Filters (PMF, SMF) and Skewness balancing

  • Geospatial cost (friction) operations that mimic PCRaster. These functions should however be more Julian, extensible and scale better.

  • Visualization, such as Perceptually Shaded Slope Map (PSSM)

  • Terrain analysis functions, such as slope, aspect, roughness, Topographic Position Index (TPI), Terrain Ruggedness Index (TRI), curvature and hillslope.

Installation ​

The package can be installed with the Julia package manager. From the Julia REPL, type ] to enter the Pkg REPL mode and run:

pkg> add Geomorphometry
