Roman Coin Finds Charta Thesauri is a volunteer hobby project that combines modern artificial intelligence (AI) with archaeological research and archaeological geodata.

Aerial Archaeology with AI: Automating Aerial Image Analysis The project focuses on archaeological geodata and the automated analysis of aerial images using YOLOv9 and PyTorch. This makes it possible to detect typical archaeological indicators: Crop marks Soil discolorations Structures of former settlements and camps Processing is carried out on high-performance servers with powerful NVIDIA graphics cards in order to efficiently analyse large image datasets. The entire application is developed in Python and is continuously improved. Goal: Automatic detection of archaeological sites from aerial imagery. Interactive Map of Roman Coin Finds A core component of Charta Thesauri is a GIS-based map of Roman coin finds: Single finds Coin hoards Spatial distribution of historical finds The data comes, among other sources, from freely accessible scholarly databases such as: Online Coins of the Roman Empire (OCRE) Coinage of the Roman Republic Online (CRRO) These data are aggregated, standardised, and displayed geographically.

Vision Charta Thesauri combines: Artificial intelligence and deep learning GIS and geodata, e.g. PostGIS and aerial imagery Archaeology and numismatics The goal is an open, modern platform for the detection, analysis, and visualisation of archaeological sites. What does \u201cCharta thesauri\u201d mean? \u201cCharta thesauri\u201d is an artificial or coined term that, strictly speaking, has never really existed \u2014 or has existed only rarely \u2014 in this exact form. There is no obvious historical document or collection bearing the precise title \u201cCharta Thesauri\u201d that appears as a significant source in common historical records or archives. Occasionally, the term is mentioned as a possible Latin expression for \u201ctreasure map,\u201d although the interpretation \u201cTabula thesauri\u201d is generally considered more common. What is well established, however, is that the term \u201cThesaurus\u201d in antiquity referred to a building within a sanctuary used for storing valuable votive offerings \u2014 in other words, a treasury or treasure house. Particularly interesting in this context is the definition given by DWDS \u2013 Thesaurus : \u201cCollection (\u2026) with thematically organized content (\u2026)\u201d and \u201c[historically] synonymous with treasury; [figuratively, archaic] abundance, wealth.\u201d What is undisputed is: \u201cCharta\u201d = charter, document, written record, contract, paper \u201cThesauri\u201d = \u201cof the treasure\u201d or \u201cof the wealth\u201d (genitive singular of thesaurus: \u201ctreasure,\u201d \u201cstore,\u201d \u201ccollection\u201d) Possible meanings depending on context: A treasure charter or a document concerning a treasure, for example in a historical or religious sense. In a bibliographic or lexicographic context, it could also mean: \u201cCharter\u201d or \u201cset of rules\u201d of the thesaurus \u2014 in other words, a framework or guideline for an organized system of knowledge. The \u201cdouble\u201d thematic suitability of the term \u2014 especially in the context of this project \u2014 ultimately led to the decision to use \u201cCharta thesauri\u201d as an artistic and overarching title.<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-997","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.7 (Yoast SEO v27.7) -
