yufengwa / GeoStats.jl

An extensible framework for high-performance geostatistics in Julia

Project goals

• Design a comprehensive framework for geostatistics (or spatial statistics) in a modern programming language.
• Address the lack of a platform for scientific comparison of different geostatistical algorithms in the literature.
• Exploit modern hardware aggressively, including GPUs and computer clusters.
• Educate people outside of the field about the existence of geostatistics.

Installation

Get the latest stable release with Julia's package manager:

] add GeoStats

Documentation

• STABLE — most recently tagged version of the documentation.
• LATEST — in-development version of the documentation.

Tutorials

A set of Jupyter notebooks demonstrating the current functionality of the project is available in GeoStatsTutorials with an accompanying series of videos:

Below is a quick preview of the high-level API:

using GeoStats
using Plots

# data.csv:
#    x,    y,       station,        precip
# 25.0, 25.0,     palo alto,           1.0
# 50.0, 75.0,  redwood city,           0.0
# 75.0, 50.0, mountain view,           1.0

# read spatial data (e.g. geotable)
𝒯 = readgeotable("data.csv", coordnames=(:x,:y))

# define spatial domain (e.g. regular grid)
𝒟 = RegularGrid(100, 100)

# define estimation problem for precipitation
𝒫 = EstimationProblem(𝒯, 𝒟, :precip)

# choose a solver from the list of solvers
𝒮 = Kriging(
  :precip => (variogram=GaussianVariogram(range=35.),)
)

# solve the problem
sol = solve(𝒫, 𝒮)

# plot the solution
contourf(sol)
