GeoArrayOps

Geospatial operations, cost and filtering algorithms as used in for elevation rasters.

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).

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 GeoArrayOps
