Charta Thesauri – AI-Based Aerial Archaeology & Roman Coin Finds

Charta Thesauri is a volunteer hobby project that combines modern artificial intelligence (AI) with archaeological research and archaeological geodata. Its aim is to automatically detect archaeological traces in aerial images and, at the same time, to build a platform for Roman coin finds.

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:

These data are aggregated, standardised, and displayed geographically.

Submit Your Own Coin Finds

Users can actively contribute to the platform:

  • Report coin find locations
  • Add descriptions
  • Contribute new data for research

This creates a growing open-data platform for archaeology and numismatics.

Open Data & API (ODbL)

Part of the data will be made freely available under the Open Database License (ODbL).

Planned features include:

  • Free API access for interested users
  • Possible commercial data acquisition, prepared in various formats:
    • KML
    • Shapefile
    • PostgreSQL / PostGIS

In addition, prepared datasets will also be offered commercially, for example for:

  • GIS analyses
  • Hobby archaeology
  • Academic research
  • Professional applications

Promoting Archaeology & Doing Good

In addition to research, Charta Thesauri also pursues social goals:

Revenue from data use or commercial exploitation goes to the animal welfare, climate protection, and species conservation projects mentioned above.

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.
