Digital Archaeology Cheat Sheet: Complete Guide to Digital Archaeological Methods & Tools

What is Digital Archaeology?

Digital archaeology is the application of digital technologies, computational methods, and data-driven approaches to archaeological research, documentation, analysis, and preservation. It encompasses everything from 3D scanning of artifacts to GIS mapping of archaeological sites, virtual reconstructions, and database management of archaeological records.

Why Digital Archaeology Matters:

• Preserves cultural heritage through digital documentation
• Enables non-invasive investigation techniques
• Facilitates global collaboration and data sharing
• Provides new analytical capabilities and insights
• Makes archaeological knowledge accessible to broader audiences
• Creates permanent records that survive physical deterioration

Core Concepts & Principles

Fundamental Principles

• Image Data: Digital photographs, orthophotos, aerial imagery
• Temporal Data: Dating information, stratigraphic sequences
• Descriptive Data: Catalog records, field notes, interpretations
• Analytical Data: Lab results, measurements, classifications

Step-by-Step Digital Archaeology Workflow

6. Create daily backups of all digital data

Phase 3: Laboratory Processing

1. Process and clean 3D models
2. Georeference spatial data
3. Enhance and analyze images
4. Integrate multi-source datasets
5. Perform digital measurements and analysis
6. Quality control and validation

Phase 4: Analysis & Interpretation

1. Spatial analysis using GIS tools
2. 3D analysis and virtual reconstruction
3. Statistical analysis of datasets
4. Comparative studies with other sites
5. Visualization and modeling
6. Hypothesis testing through digital methods

Phase 5: Publication & Preservation

1. Prepare data for archiving
2. Create metadata documentation
3. Publish in digital repositories
4. Develop public engagement materials
5. Ensure long-term accessibility
6. Plan for data migration and updates

Best Practices & Practical Tips

Data Collection Best Practices

• Always collect more data than you think you need – it’s easier than returning to the field
• Maintain consistent naming conventions across all files and folders
• Document your methodology thoroughly for reproducibility
• Create multiple backups using the 3-2-1 rule (3 copies, 2 different media, 1 offsite)
• Test equipment thoroughly before fieldwork begins
• Keep detailed logs of all data collection activities

Processing & Analysis Tips

• Start with simple analyses before attempting complex interpretations
• Use version control for datasets and analysis scripts
• Validate results using multiple methods when possible
• Document all processing steps for transparency and repeatability
• Save intermediate results to avoid re-processing if problems occur
• Create regular checkpoints during long processing tasks

Collaboration & Sharing

• Establish data sharing agreements early in projects
• Use standardized metadata to facilitate discovery
• Consider cultural sensitivities when sharing indigenous heritage data
• Provide multiple access levels (public, researcher, restricted)
• Include uncertainty information in all datasets
• Create user-friendly documentation for non-specialists

Long-term Preservation

• Use open, non-proprietary formats when possible
• Include format migration in preservation planning
• Maintain multiple copies in different geographic locations
• Regular format validation and integrity checking
• Document file relationships and dependencies
• Plan for institutional changes and data transfer
