Reproducibility
To reproduce your current settings, run archeoViz with the following R command (adjust the “objects.df” and “refits.df” parameters to your needs):
archeoViz
archeoViz
is a packaged R Shiny application for the
visualisation, exploration, and web
communication of archaeological spatial data. It includes
interactive 3D and 2D visualisations, can generate cross
sections and maps of the remains, and display an
interactive timeline of the work made in a site. Simple
spatial statistics can be performed (convex hull, regression
surfaces, 2D kernel density estimation), as well as exporting
data to other online applications for more complex methods.
archeoViz
can be used locally or deployed on a server,
either by allowing the user to load data through the interface or by
running the app with a specific data set. The app interface is available
in English, French, German, Italian, Portuguese, Romanian, and Spanish.

Use
Having archaeological remains from a given site,
archeoViz
is designed to lower the technical barriers to
fulfill three objectives:
- basic spatial exploration and generation of simple graphical reports;
- fast pre-publication of archaeological data, intended for the scientific community;
- fast deployment of a visualisation and communication tool intended for a broader audience.
In addition, archeoViz
is a suitable pedagogical
resource for teaching spatial analysis in archaeology, data structuring,
open science, and reproducible workflow.
N.B.: consequently, archeoViz
is not intended to replace
more sophisticated analysis tools (e.g., GIS, statistical packages,
etc.)
Spatial Information in archeoViz
Archaeologists record the location of archaeological objects at different scales and granularity. Accordingly, they use different geometrical concepts to represent location.
Points, Exact Location: Plotted Objects
Using grid coordinates or electronic “total station” enables
recording the individual location of objects on the field. In that case,
the location are represented as points in archeoViz
(triplets of x, y and z coordinates).
Points, Vague Location: Spits, Buckets, Sieved Objects, and Recording Errors
However, it is also common that x, y, z, coordinates by object are not available, for different reasons due to:
- recording errors, loss of information, resulting in the need to replace one of several coordinates values by ranges (e.g., a X value is missing for an object and is replaced by the minimal and maximal X values of the square where this object was found);
- choice of method (e.g., excavation made and recorded using spits of arbitrary depth, sieved objects, etc.).
In all these cases, we have to deal with vague location, when objects cannot be located as points but are somewhere between ranges of coordinates. Vague location can concern one, two, or the three spatial dimensions (the x, y, z coordinates, respectively).
Note that this feature can also be used to deal with the imprecision of topographical instruments.
Lines
Lines are useful geometries for representing relationships. In
archaeology, these can be refitting
relationships between object fragments, orientation (fabric measurements, etc. Lines are
generated from data loaded as refitting data, either from the “Data”
tab, or with the refits.df
parameter of the
archeoViz()
function.
Surfaces
Surfaces are useful geometries for representing ground levels,
trenches, pits, etc. In archeoViz
, this can be achieved by
defining a subset of points summarising the desired surface, then
displaying the convex hull of this
subset.
Refittings and Fabric Measurements
Refittings
Refittings are usually recorded by archaeologists in two ways:
- by sets of refitting objects: using a two columns table, where a row corresponds to an object. The first column stores the object’s unique id and the second column stores the id of the set of refitting objects this object belongs to.
- by refitting relationships: using a two columns table, where a row corresponds to a relationship. The first column stores the first object’s unique id and the second column stores the second object’s unique id.
Although the second data structure is more accurate, the first is more commonly used.
archeoViz
processes and represents the two data
structures in two ways:
- sets of refitting objects must be described using a specific column
in the
objects.df
table (e.g.object_refits
) and are represented by the color of points in the plots (like any other variable); - refitting relationships must be described using the
refits.df
table and are visualised as segments connecting the refitting objects in the plots.
Fabric Measurements
So far, archeoViz
does not handle fabric measurements
properly. However, the process used to represent refittings can also
adapted and used to represent fabric measurements. This requires to
distort the data structure as follows:
- assuming that fabric measurements were recorded with two measurements on each object (and not with dip and plunge measurements),
- different unique
id
values must be given to the two points, and - the two measures are processed as if they were two refitting objects.
See an example of this method here.
Data Format
Three types of data can be loaded in archeoViz
:
- an “objects” table (mandatory), with data about the objects;
- a “refits” table (optional), with data about the refitting objects;
- a “timeline” table (optional) giving the year when each square of the site was excavated or surveyed.
Formatting Data
The tables must be CSV files with the first row containing the column labels. Contents in HTML are allowed. This makes it possible, in particular, to add links to external resources (e.g., to objects permanent identifier in other databases, or to concepts identifiers in standard ontologies / thesauri, etc.).
Formatting your data can be done:
- either using a spreadsheet editor on your machine to generate CSV files;
- or, for the
objects table,
using the SEAHORS application to load your data, define the variables (in the “Load data” tab), and export it to thearcheoViz
format (in the “Table” / “archeoViz exports” tab). It is also possible to directly send the data to an onlinearcheoViz
instance.
Objects Table
A row describes a single object with the following mandatory fields:
- id: alphanumerical value, unique identifier of the object
- xmin: numerical value, coordinate of the object on the X axis
- ymin: numerical value, coordinate of the object on the Y axis
- zmin: numerical value, coordinate of the object on the Z axis (positive depth value)
- layer: alphanumerical value, identifier of the object’s layer
- object_type: alphanumerical value, category of the object
In addition, optional fields are possible, including:
- square_x: alphanumerical value, identifier of the square on the X axis
- square_y: alphanumerical value, identifier of the square on the Y axis
- year : numerical value, year when the object was excavated
- xmax: numerical value, when the X location of the object is included in a range of X coordinates
- ymax: numerical value, when the Y location of the object is included in a range of Y coordinates
- zmax: numerical value, when the Z location of the object is included in a range of Z coordinates
- object_edit: unlimited number of additional
variables describing the object (field names must start with
object_
and have different suffixes)
The labels of the squares of the grid:
- are ordered alpha-numerically;
- are not displayed to avoid erroneous displays, if the number of labels does not correspond exactly to the total number of 100 (cm, m, km) squares that can be defined in the range of minimum and maximum coordinates contained in the xmin and ymin variables;
- can be completed with the
add.x.square.labels
andadd.y.square.labels
parameters of thearcheoViz()
function in order to add the missing labels (on the X and Y axes of the grid, respectively).
Refitting Table
A data table with two columns can be uploaded for refitting data (CSV
format). Each row must contain the unique identifiers of two refitting
objects (corresponding to the values of the id
column in
the objects table).
Timeline Table
A table (CSV format) can be uploaded about excavation history. Row gives the year when each grid square of the site was excavated or surveyed. This table must include the following variables:
- year: numerical value, the year of excavation
- square_x: alphanumerical value, identifier of the excavated square on the X axis
- square_y: alphanumerical value, identifier of the excavated square on the Y axis
Background Drawing
A background drawing can be displayed in the 3D and Map plots. This
feature makes it possible, for example, to show a site map behind a
point cloud. It requires a data table in which each row gives the X and
Y coordinates of the points to be used to draw. Note that the lines will
be drawn following the order of the points in the table. The coordinates
system used must be the same that the one used for the objects. To draw
several lines, an additional column (named “group”) is required,
containing for each point the unique identifier of the line to which
this point belongs to. The data set is loaded using the
background.map
parameter.
Units
By default, all distances in archeoViz
are in
centimeter. However, it can be changed by giving the unit
parameter one of the following value: “cm”, “m”, “km”. This parameter
determines the contents of the legend of the square size.
Data Input
There are four ways to input data in archeoViz
:
- uploading data tables through the “Input data” tab,
- loading data tables through the
archeoViz
function’s parameters, in the R interface; - uploading data tables through URL parameters, when using an online
instance of
archeoViz
. - generating random data in the “Input data” tab;
Through the Application Interface
The three types of tables can be loaded in the “Input data” tab. The CSV separator (one of: comma, semicolon, tabulation) and the character used for decimal points (period or comma).
Through URL parameters
The URL of an online instance of archeoViz
can include
the parameters:
objects.df=
refits.df=
timeline.df=
whose values must be the URL of a CSV file observing the
archeoViz
format described above. For example: https://analytics.huma-num.fr/archeoviz/en/?objects.df=https://zenodo.org/record/8003880/files/bilzingsleben.csv
Generating Random Data
Using randomly generated data is made possible for demonstration
purposes. To activate this feature, set the slider in “Input data” to a
value higher than 0 (setting the value back to 0 deactivates the
feature). An “objects” data set, a “refits” data set, and a “timeline”
data set are generated, making it possible to test all the
archeoViz
functionalities.
Through the R function parameters
archeoViz
’s launching function
(archeoViz()
) can be run without parameter
or by using the objects.df
, refits.df
, or
timeline.df
parameters to input data.frames about the
archaeological objects, refitting relationships between these objects,
and the chronology of the excavation, respectively.
archeoViz(objects.df = NULL, # data.frame with data about the objects
refits.df = NULL, # data.frame for refitting objects
timeline.df = NULL) # optional data.frame for the excavation timeline
Rotating the points
You can change the orientation of the points in the plan. In the “Data” tab, select a value (in degrees) and click on the “Validate selection” button to confirm.
Data Sub-setting
Once data are loaded, a sub-selection of the data can be done in the left side menu. Grouping can be done by crossing the following parameters: the mode of location, the layers, and the category of object.
By Location Mode
If all the objects have exact location or vague location, then no option is proposed. However, if the dataset includes both exact and vague location, then it is possible to select only one or both of these options.
By Layer or Object Category
The data can be grouped in two ways: either based on their layer or on the selected “object_” variable. This option determines the colours of the points in the 3D and 2D plots and how to group points when computing convex hulls and 3D regression surfaces. Sub-sets can be defined by object categories, using the “variable” and “values” fields. Once one of the “object_type” (or other possible “object_” variables) is selected, its values appear below and can be selected using the tick boxes. The selection must be validated by clicking on the “Validate” button. This selection determines the data to be displayed in the plots and tables.
Interactive visualisation
General features
The plots in the “3D plot”, “Map”, “Section X”, and “Section Y” tabs
are generated using the plotly
library. All the plots are dynamic and include a menu bar above the plot
with several options (generating an image file, zooming, moving the
view, etc). See details on the plotly
website.
Clicking on a legend’s item modifies the display:
- a simple click on an item activates/deactivates its display;
- a double click on an item displays this item only (another double click cancels it).
This feature makes it possible to choose which layers are shown. In addition, the size of the points can be set and whether the refitting relationships must be represented or not.
Finally, clicking on a point displays information about that point in the table below the plot.
Visualising Spatial Uncertainty
In archeoViz
, a distinction is made between exact
location (given as x, y, z coordinates) and vague locations (given as
ranges of coordinates). Both types of locations can be displayed. The
uncertainty of vague locations can be visualised by representing objects
not as points but as lines, planes, and volumes (if ranges of
coordinates are given for one, two, or three spatial dimensions,
respectively). Note that this feature is resource intensive and using it
with too much data can significantly slow down the application.
Graphical outputs
Several graphical outputs can be generated in
archeoViz
.
- The plots in the “3D plot”, “Map”, “Section X”, and “Section Y” tabs
can be exported:
- in SVG format (by clicking on the “camera” icon in the menu bar above the plot),
- as interactive plots in HTML format, by clicking on the “Export” button.
- The small map in the “Section X” and “Section Y” tabs can be exported in SVG by clicking on the “Download Map” link.
- The plan of the excavation chronology can be exported in SVG format by clicking on the “Download” button.
Spatial statistics
archeoViz
includes some spatial analysis
functionalities, intended for basic and exploratory use.
Regression surfaces
In the “3D plot” tab, clicking on “Compute surfaces” and “Validate”
displays the regression surface associated with each layer (with at
least 100 points). The surfaces are computed using the generalized
additive model implemented in the mgcv
package.
Convex hulls
In the “3D plot” tab, convex hulls can be displayed as follows:
- tick the “Convex hulls” box,
- select, from the menu that appears, the subsets of points for which convex hulls are to be calculated,
- click on “Validate”.
Convex hulls associated with each subsets with at least 20 points are
displayed. The convex hulls are computed using the cxhull
package.
2D kernel density
In the “Map” tab, ticking the “Compute density” box and clicking on
“Validate” generates a map with contour lines showing the points’
density. Density can be computed for all the points together or by layer
(with at least 30 points). The 2D kernel density is computed with the
kde2d
function of the MASS
package (through ggplot2
).
Reproducibility
archeoViz
is, by definition, an interactive application.
However, several features guarantee the reproducibility and
communicability of the result of interactions with the application.
- The 3D visualisation can be exported in an interactive HTML standalone format, considering the data selection made by the user.
- In the “Reproducibility” tab, an R command is dynamically generated, considering the current application settings made by the user.
- In a more advanced use, the URL parameters makes it possible to set an online instance of the application parameters of interest and to communicate it by sending the URL.
Exports from and to Third-party Applications
archeoViz
was designed as one of the building blocks of
a decentralised digital ecosystem for archaeological data and analysis.
In this perspective, features and functions are distributed in multiple
interconnected applications, rather than concentrated into few systems.
Consequently, data can be exported and imported between
archeoViz
and other web-based applications. Note that, so
far, the export functionalities are only available when using online
archeoViz
instances.
Export from archeoViz
Data can be exported to other online applications from
archeoViz
“Statistics” tab. Some exports are possible only
for specific types of data or if a minimum number of values is
satisfied.
archeofrag
is an R package and web application to assess and evaluate the
distinctions betwen archaeological spatial units (e.g. layers) based on
the analysis of refitting relationships between fragments of objects.
The web version of the application includes methods to measure the
cohesion and admixture of spatial units, and compare it to simulated
data. If an instance of archeoViz
is launched with refitting data, then this data can be analysed
with archeofrag
. See an example here.
The Seriograph
is a web application (part of the SPARTAAS
collection) to visualise changes in the quantitative distribution of
artefacts types in ordered or unordered series of spatial units. Export

The following URL launches the Bilzingsleben dataset, pre-setting the app to:
- groups the points by variable (parameter
default.group
, with walueby.variable
instead ofby.layer
) - selects only the “Antlers” (parameter
class.values
) - redefines the size of the square grid (parameter
square.size
, 500 instead of the 100 default value) - enable the immediate display of the plots (parameter
run.plots
) - modifies the title of the page (parameter
title
) - modifies the content of the home page with basic HTML contents
(parameter
home.txt
)
Note that the parameters add.x.square.labels
,
add.y.square.labels
, location.mode
, and
class.values
, which accept simple or multiple values in the
R interface (e.g., c(“value1”, “value2”)) only accept one value when set
as URL parameters (this is a restriction due to the URL syntax).
