01 — Field Context

Active Archaeology.
Original Methodology.

This research was conducted as part of the Programme for Belize Archaeology Project (PfBAP) field school in Orange Walk, Belize — an active, multi-institution archaeological excavation site focused on Mayan civilization. Matthew traveled to Belize as an undergraduate at Humboldt State University to conduct original methodology research, not as a passive participant but as an independent researcher developing a novel spatial documentation approach from the ground up.

The core research question was methodological: could high-definition digital photography, processed through photogrammetry software, produce three-dimensional digital surrogates of Mayan artifacts and settlement features that were accurate and detailed enough to be meaningful for spatial and archaeological analysis? And could those 3D models be integrated into ArcGIS and ArcScene for proper geospatial contextualization?

The answer was yes — and the methodology Matthew developed in the field became the basis of his undergraduate research output, earning three academic awards for excellence in GIS research and spatial analysis from Humboldt State University.

How 2D Photography Becomes
3D Spatial Intelligence

Systematic HD Photography

Artifacts and settlement features were photographed systematically from multiple controlled angles using HD digital cameras — capturing sufficient overlap and coverage for photogrammetric reconstruction. Lighting, distance, and angle consistency were critical to model accuracy.

Photogrammetric Processing in Strata Foto

The HD photo sets were processed in Strata Foto, which identified common feature points across overlapping images and computed three-dimensional point clouds and mesh surfaces — reconstructing the physical geometry of each artifact or structure from pure photographic data.

3D Surrogate Generation

Processed photo sets yielded detailed 3D digital surrogate models — textured mesh representations of the original physical objects and settlement features. These surrogates preserve spatial geometry that physical artifacts cannot: they can be measured, rotated, cross-sectioned, and analyzed without touching the originals.

ArcGIS / ArcScene Integration

3D surrogates were imported into ArcGIS and ArcScene, placing the models within proper geospatial context — georeferenced to the actual excavation coordinates. This enabled spatial analysis of artifact distribution, settlement layout, and site topology in true 3D GIS space.

03 — What Was Modelled

Artifacts & Settlements

Physical Artifacts

Object-Scale

Mayan material culture recovered from the PfBAP excavation was photographed and modelled as 3D digital surrogates — creating permanent, measurable, high-fidelity digital records that can be shared, studied, and analyzed without physical handling of the originals.

Excavated feature documentation

Settlement Layout

Site-Scale

Beyond individual artifacts, the methodology was applied at settlement scale — using photogrammetry to document Mayan architectural features and site layout, producing 3D spatial data that could be georeferenced and analyzed within ArcScene for settlement pattern research.

05 — Why This Matters

Pioneering Digital
Heritage Preservation

At the time this research was conducted, applying photogrammetry pipelines to active field archaeology — especially as independent undergraduate research — was genuinely ahead of the curve. The methodology Matthew developed addresses one of the most fundamental challenges in archaeology: physical artifacts are fragile, rare, and irreplaceable. Once excavated, they can be lost to deterioration, damage, or institutional dispersal.

3D digital surrogates change that equation entirely. A surrogate can be shared globally, measured precisely, re-analyzed decades later, and preserved indefinitely — without ever touching the original object. This project demonstrated that a GIS-trained researcher, armed with an HD camera and the right software pipeline, could produce research-grade 3D documentation in the field.

Non-Destructive Documentation

3D surrogates capture full spatial geometry without any contact with fragile Mayan artifacts — preserving both the object and its measurable spatial properties.

Globally Shareable Research Data

Digital surrogates can be distributed to researchers worldwide, enabling collaborative analysis of Belizean Mayan material culture without physical object transport.

GIS-Integrated Spatial Context

By placing 3D models within ArcScene at actual excavation coordinates, the methodology preserves not just the artifact but its spatial relationship to the settlement — critical for archaeological interpretation.

Replicable Field Methodology

The HD photography + Strata Foto + ArcScene pipeline was designed to be reproducible with accessible equipment — lowering the barrier for 3D documentation at under-resourced field sites.
