Overview
In many fields of science, such as mining engineering, hydrogeology, petroleum engineering, and environmental sciences, traditional statistical methods fail to provide unbiased estimates of resources due to the presence of geospatial correlation. Geostatistics (a.k.a. geospatial statistics) is the branch of statistics developed to overcome this limitation. Particularly, it is the branch that takes geospatial coordinates of data into account. Some major highlights of GeoStats.jl are:
- It is simple: has a very short learning curve and requires writing minimal code 😌
- It is general: supports all types of geospatial domains, including unstructured meshes 👍
- It is native: fully written in Julia for maximum flexibility and performance 🚀
- Has an extensive library of algorithms from the geostatistics literature 📚
Our JuliaCon2021 talk provides an overview of geostatistical learning, which is one of the many geostatistical problems addressed by the software:

Installation
Get the latest stable release with Julia's package manager:
using Pkg
Pkg.add("GeoStats")Quick example
Below is an example of geostatistical interpolation of point data over a Cartesian grid with a Kriging model:
# load framework
using GeoStats
# load visualization backend
import CairoMakie as Mke
# attribute table
table = (; Z=[1.,0.,1.])
# coordinates for each row
coord = [(25.,25.), (50.,75.), (75.,50.)]
# georeference data
geotable = georef(table, coord)
# interpolation domain
grid = CartesianGrid(100, 100)
# choose an interpolation model
model = Kriging(GaussianVariogram(range=35.))
# perform interpolation over grid
interp = geotable |> Interpolate(grid, model)
# visualize the solution
viz(interp.geometry, color = interp.Z)
