ATOR (Arc-Team Open Research).
The blog spreads tests, problems and results of Arc-Team research in archaeology, following the guidelines of the OpArc (Open Archaeology) project.
This is the second presentation we gave at ArcheoFOSS 2016. This time the topic is more related with geoarchaeology and regards geTTexture (the open source application we developed in order to speed up the sedimentation est).
Here below is the link to the original presentation, for the reader who wants to see it directly online:
For those who prefer to see it on youtube, I just uploaded it on our channel:
Like for last post, I report here below a short abstract, describing shortly each slide of the presentation:
SLIDE 1
Title and overview
SLIDE 2
Compiling the archaeological recording sheet is one of the most time-expensive operation during an archaeological project both doing it manually...
SLIDE 3
... or using a database.
SLIDE 4
Considering the Italian standards (ICCD, "Istituto Centrale per il Catalogo e la Documentazione"), often new archaeologists have difficulties in describing the composition of the archaeological layer.
SLIDE 5 and 6
SLIDE 7 and 8
No particular difficulties are detected in describing the artificial elements.
SLIDE 9 and 10
A little bit more complicated is considered to describe the organic and oranogenic elements.
SLIDE 11 and 12
The most difficult field is considered the geological one.
SLIDE 13
Geological materials are splitted into two categories: skeleton and fine earth
SLIDE 14 and 15
The skeleton is normally simpler to identify (both in the field and in the lab).
SLIDE 16 and 17
The fine earth is maybe the most complicated archaeological element to identify on the field, while specialist (geoarchaeologists) need to use specific equipement in the lab.
SLIDE 18
Fine earth definition on the field is foten carried on with anametric and sobjective methodology.
SLIDE 19
Like feel, ball and ribbon test
SLIDE 20
The sedimentation test gives more objective results with a minimum metric value.
SLIDE 21
Arc-Team used validated the use of sedimentation test also in emergency excavation (which have a stricter time-table respect other archaeological projects)
SLIDE 22
Thank to +Mattia Segata (Arc-Team's geoarchaeologist at ATLAB), the basic methodology has been improved considering the Strokes' Law.
SLIDE 23
+Giuseppe Naponiello (Arc-Team DataBase and WebGIS expert) improved a PostreSQL dabatase, developed on the Italian archaeological recording sheet. The Database is able to integrate the data coming from the sedimentation test.
SLIDE 24
Future integration are planned for basic analytical chemistry analyses on the field.
SLIDE 25
And for more specific laboratory analyses (e.g. Energy Disperive X-ray Spectrometry).
SLIDE 26
The DataBase can be easily integrated into a WebGIS
SLIDE 27
The slides is just a demonstration of the software (the code is taken from a prototype).
SLIDE 28
The slide is just an example of one of the videotutorial Arc-Team is producing to explain the sedimentation test and the use of geTTexture.
SLIDE 29
geTTexture will be one of the open source application for archaeology which Arc-Team is developing and that will compose the suite Arc-Tool.
SLIDE 30
Another extension of geTTexture Arc-Team is working on is related with colorimetry. The idea is to integrate a tool to record anametric analyses
SLIDE 31
or metric data coming from Open Hardware devices (e.g. Public Lab spectrometer)
as I wrote in this post, I am building a very simple Android app in order to use geTTexture (the automatic Soil Texture Tirangle +Giuseppe Naponiello developed) from the mobile, directly on the field.
Thanks to the work of +Giuseppe Naponiello the website is now optimized also to be viewed from a mobile's monitor (due to the fact that now the Soil Triangle can be automatically scaled), so that if you have an internet connection on your excavation, you can use geTTexture to define the soil texture of your archaeological layers in a semi-automatic way.
Here below are two screenshots of the mobile app:
geTTexture mobile (upper screen)
geTTexture mobile (lower screen)
By now the mobile app is a simple link the geTTexture developed with MIT App Inventor. Nevertheless I uploaded also the source code of the project on Arc-Team's githup repository (released under General Public license), where you can find also the main software (released under Creative Commons Attribution). Here you can find the binary apk file, to install the app on your mobile. If you want to use geTTexture on your PC or laptop, than you can use this direct link.
Have a nice day!
