Archaeologists use cutting-edge tools to map and document sites. Total stations, , and create precise 3D models and measurements. These methods preserve crucial info about artifact locations and site layout before excavation alters everything.
Site documentation is vital for piecing together past human activities. Detailed plans and profiles show how artifacts and features relate spatially and chronologically. Digital tech like and 3D modeling revolutionize how archaeologists analyze and share their findings.

Importance of site documentation
Preservation of archaeological information as sites often destroyed or altered during excavation
Accurate documentation ensures original context and relationships between features and artifacts recorded for future reference and analysis
Detailed site documentation allows reconstruction of past human activities and
Spatial relationships between features and artifacts provide insights into site function, chronology, and social organization
Standardized documentation methods enable comparisons between different sites and regions
Consistent data collection facilitates integration of information from multiple sources and development of broader archaeological interpretations
Site documentation crucial for effective management and protection of archaeological resources
Accurate records inform decisions related to site conservation, restoration, and public outreach
Site Documentation Techniques and Interpretation
Creation of site plans
Site plans horizontal representation of archaeological site, showing of features and artifacts
Created using surveying equipment (total station, GPS) or photogrammetry
Include scale, north arrow, legend, and key elevations
Used to understand site layout, organization, and relationships between features
Profiles and sections vertical representation of archaeological site, showing and relationships between layers
Created by drawing exposed faces of excavation units or trenches
Include scale, elevations, and descriptions of soil layers and features
Used to understand site formation processes, chronology, and changes over time
Interpretation combines horizontal and vertical information to reconstruct past human activities and site development
Identify patterns, associations, and anomalies in spatial distribution of features and artifacts
Integrate stratigraphic information to establish relative and absolute chronologies
Collaborate with specialists (geomorphologists, archaeobotanists) to interpret site formation processes and paleoenvironments
Digital technologies in archaeology
Geographic Information Systems (GIS) computer-based tools for capturing, storing, analyzing, and displaying spatial data
Integrate various types of archaeological data (site plans, artifact distributions, environmental information)
Facilitate creation of interactive maps and visualizations for research and public outreach
3D modeling and visualization technologies (photogrammetry, laser scanning) allow creation of detailed 3D models of archaeological features and artifacts
3D models used for documentation, analysis, and visualization purposes
Virtual and augmented reality applications enhance public engagement and understanding of archaeological sites
Database management systems store, organize, and query archaeological data
Relational databases integrate spatial and attribute data
Facilitate data sharing, standardization, and long-term preservation
techniques (satellite imagery, aerial photography, geophysical prospection) provide non-invasive methods for site detection and mapping
Remote sensing data guides excavation strategies and contributes to landscape-scale archaeological analyses
