v0.4.1

• Migrate problem and solution interface to GeoStatsBase.jl
• Sequential Gaussian simulation on point collections

v0.4.0

This is an important release of the project with a whole new infrastructure for general estimation and stochastic simulation problems over general domains. It is also an informal call to researchers interested in contributing to the GeoStats.jl ecosystem.

New features

• Abstraction of problems and solvers for geostatistical estimation/simulation
• New base package GeoStatsBase.jl for solver writers
• Kriging and Sequential Gaussian simulation solvers
• Parallel stochastic simulation

v0.3.7

• Solve covariance instead of variogram if the latter possesses the 2nd-order stationarity property
• Add power, cubic, pentaspherical and sine hole theoretical variogram models
• Add method isstationary for theoretical variogram models
• Add Kriging with external drift
• Add documentation for plotting

v0.3.6

• Add function GeoStats.examples() for launching notebooks locally
• Add visual regression tests for plot recipes

v0.3.5

• Restructure documentation
• Add examples in the form of Jupyter notebooks

v0.3.4

• Add empirical omnidirectional semi-variogram
• Add plot recipes for empirical and theoretical variograms

v0.3.3

• Fix spherical variogram model
• Add more tests

v0.3.2

• Add ellipsoid distance in 2D and 3D as a way of modeling anisotropy.
• Add haversine distance between two latitude/longitude pairs.
• Replace immutable by struct and type by mutable struct in Julia v0.7.

v0.3.1

• Use Parameters.jl until default field values become part of the language (see JuliaLang/julia#10146).
• Add anisotropic variogram models by means of custom distance functions.
• Add composite (additive) variogram model.

v0.3.0

This is the first release of the package with support to Julia v0.6. We kindly ask users to update to the current version of the language. Below is the list of changes:

• Add Matérn family of variogram models
• Require SpecialFunctions.jl on Julia v0.6 and later
• Require Julia v0.6
