GeoArrayOps
Geospatial operations, cost and filtering algorithms as used in for elevation rasters.
This is a work in progress
Functionality
- Terrain filters, such as Progressive Morphological Filters (PMF, SMF)
- 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 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 https://github.com/Deltares/GeoArrayOps.jl
