Spatial analysis


Dynamic image analysis to identify ancient artifacts in soil samples.


QGIS Python script/plugin for computing azimuth, horizon altitude, and celestial declination of a specific bearing indicated by a line segment selected by a user.


The ArchaeoLines plugin displays any combination of declination arcs most relevant to archaeo- or ethnoastronomical studies.


R package for the analysis of the fragmentation of archeological objects.


A packaged R ‘Shiny’ application for the visualisation, interactive exploration, and web communication of archaeological spatial data.


Estimates artifact class diversity in multiple geographic regions.


An R package that provides functions for 3D tessellation with Voro++ and subsequent horizontal cutting of the resulting polygons for 2D plotting. It was developed for archaeological spatiotemporal data, but may as well be used for other three dimensional contexts.


This is an example implementation of chrono-spatial modelling of settlement activities.


A QGIS 3 plugin for spatio-temporal interpolation of archaeological settlement evidence.


An R implementation of the Fast Marching Method (FMM), first developed by Sethian (1996), with the modifications of Silva and Steele (2012, 2014). Also included is a spatial wrapper function that makes it easier to model dispersal scenarios in geospatial domains, as originally envisaged for the study and simulation of prehistoric dispersals


ArcGIS toolbox for fuzzy viewshed calculation.


Code for Geostatistics in ethnographic contexts.


Solve the distribution regression problem for noncontiguous geospatial features. The use case documented here is for modeling archaeological site locations.


Provides the functionality to calculate Least Cost Paths (LCPs) which are often, but not exclusively, used in archaeological research. This package can be used to apply multiple cost functions when approximating the difficulty of moving across a landscape, as well as taking into account traversing across slope and other costs such as landscape features. This package also provides functionality to validate the accuracy of the computed LCP relative to another path.


Tool for calculating the largest empty circles and estimation of archaeological sites theoretically to be expected in region of interest, an implementation of the method published by Andreas Zimmermann and Karl Peter Wendt (2003).


Code repository of the book by Oliver Nakoinz and Daniel Knitter “Modelling Human Behaviour in Landscapes – Basic concepts and modelling elements”.


Provides the facility to calculate non-isotropic accumulated cost surface and least-cost paths using a number of human-movement-related cost functions that can be selected by the user. It just requires a Digital Terrain Model, a start location and (optionally) destination locations.


R script for analyzing presence/absence data in irregularly distributed archaeological survey units.


Implements Near Presence Cluster Analysis, a statistical method for identifying spatial clustering within presence / absence data observed in irregularly distributed areal observation units.


R code for doing fabric analysis.


App to do some artifact orientations analysis.


R Package to reconstruct paths using archaeological monuments, model parameters of infrastructure and evaluate those parameters, model parameters of infrastructure and evaluate those parameters.


Distance matrices between islands normalised over Pleistocene time.


Distance matrices between islands normalised over Pleistocene time. A complete ground-up rebuild of PleistoDist for use with R.


Models relationships between elements in a terrain model, connecting pixels according to their height difference.


Calculates visible surface from a given observer point over a digital elevation model. The plugin is intended for more complex modelling, such as the depth below the visible horizon or generation of intervisibilty networks between groups of points. It is particularly performant for multiple viewshed calculations form a set of fixed points.


Reads an SDR33 data logger file and using the angular observations recorded therein to triangulate the position of points of interest.


R Shiny application that allows easy and quick exploration of the spatial distribution of archaeological objects.


A toolbox for modelling human perception of topography for QGIS, based on QGIS viewshed module.


Offers methods to shoreline date Stone Age sites located along the Norwegian Skagerrak coast based on their present-day elevation and the trajectory of past relative sea-level change.


Analysis of spatial gradients in radiocarbon dates.


A plugin to connect with totalopenstation software developed as part of the IOSA project.


GIS toolbox for estimating the duration of ancient sail-powered navigation.


R implementation of the Uniform Probability Density Analysis approach
