Methods for comparing spatial patterns in raster data This is the fourth part of a blog post series on comparing spatial patterns in raster data. More information about the whole series can be found in part one. This blog post focuses on the comparison of spatial patterns in categorical raster data for overlapping regions.
Methods for comparing spatial patterns in raster data This is the third part of a blog post series on comparing spatial patterns in raster data. More information about the whole series can be found in part one. This blog post focuses on the comparison of spatial patterns in continuous raster data for arbitrary regions. Thus, the shown methods require two continuous rasters, which may have different extents, resolutions, etc.

I received a grant from the Marie Skłodowska-Curie Actions Postdoctoral Fellowships (MSCA-PF) program: between August 2024 and August of 2026, I will be at the University of Muenster, Germany, working on a project named PRISM: PReservation and RecognItion of Spatial patterns using Machine learning . The project’s primary goal is to develop and compare methods for validating and including spatial patterns in machine learning.
The spatial kinetic Ising model is a simple model of spatial patterns that can be used to simulate the evolution of spatial patterns over time. Its two main parameters are B and J, which control the external pressure and the local autocorrelation tendency, respectively. Both of them have a strong effect on the results of the spatial kinetic Ising model. Thus, the question is how to find the best values of these parameters for a given situation.
A two-dimensional Ising model is an idealized physical system that consists of a lattice of binary variables ( magnetic spins ) that can be in one of two states: up or down. Each spin’s state is influenced by its neighbors: the more neighbors in the same state, the more likely the spin will be in the same state.
Spatial signatures represent spatial patterns of land cover in a given area. Thus, they can be used to search for areas with similar spatial patterns to a query region or to quantify changes in spatial patterns. The approaches above are implemented as lsp_search() and lsp_compare() functions of the motif R package, respectively. At the same time, it is possible to create other, more customized workflows.
The spatial signatures of categorical rasters are a set of numbers that describe the spatial patterns of the provided variables. Next, they allow for further operations such as searching, comparing, or clustering. Less known is that they can also be used to extract information about the composition and configuration of spatial patterns. This blog post shows how to do it using the motif R package.
