Prijepolje Archaeological LiDAR

UAV Mapping & Interpretation of Four Sites

Prijepolje Archaeological LiDAR combines four-site UAV LiDAR/RGB acquisition, 2 cm orthophoto, 10 cm DTM and multi-method relief analysis with cautious archaeological interpretation vectors.

Project context

Seeing the archaeological landscape where vegetation and terrain limit field access

The Museum in Prijepolje needed a non-invasive spatial basis for four sites with very different terrain, vegetation and accessibility. The project combined UAV LiDAR and RGB imaging so archaeologists could read both visible context and subtle ground morphology beneath vegetation.

Overview showing the spatial relationship of the four surveyed archaeological areas.

UAV acquisition

Four sites. One controlled LiDAR + RGB workflow.

Flight planning, permissions, GNSS orientation control and terrain-aware UAV missions were coordinated across Mileševac, Pustinja Monastery, Pustinja–Gradina and Kolovrat. DJI Matrice 350 RTK with Zenmuse L2 captured LiDAR and RGB data on 27–28 February 2026.

Point cloud & terrain

From dense returns to a readable bare-earth surface

Raw INS, LiDAR and imagery were processed and georeferenced, adjacent scan lines were adjusted, and automated classification was followed by manual inspection. The resulting point clouds and ground class supported 10 cm terrain modelling and specialist relief analysis.

High-resolution imagery

2 cm RGB context alongside the terrain evidence

Orthophotos preserved the visible surface, access routes and site context at 2 cm/pixel, complementing the terrain-under-vegetation information derived from LiDAR.

Archaeological interpretation

Interpretation that keeps uncertainty visible

MapSoft used several complementary terrain visualizations — including SLRM, slope, Sky-View Factor, openness and hillshade — because no single rendering reveals every subtle feature. Detected structures were digitized and qualified rather than automatically presented as archaeology.

Potential archaeological features remain targets for field verification. Modern earthworks and anthropogenic features were separated from stronger archaeological evidence instead of being overclaimed.

Quality & validation

Control the geometry. Then control the interpretation.

Coverage was checked through projection centres, image inventory and LiDAR coverage mapping. Orthophoto control residuals remained within centimetre-level ranges in the documented check, while classification and interpretation were additionally reviewed manually.

X residual−1.0 → +2.4 cmdocumented orthophoto check
Manual reviewClassification + interpretationfield verification remains part of archaeological judgement
Adjacent LiDAR scan lines were adjusted using suitable artificial features in overlap areas. Automated TerraScan classification was followed by manual inspection and correction, and interpretation was checked across several complementary relief methods so the archaeological reading did not depend on a single rendering.
Delivered outputs

A complete interpretation-ready heritage dataset

The final package connected measurement, terrain production and specialist interpretation so the Museum could use the same spatial foundation for documentation, comparison and targeted follow-up investigation.

What this project proves

From UAV reality capture to disciplined terrain intelligence for archaeology

Prijepolje proves MapSoft can combine high-density UAV LiDAR, RGB imaging, GNSS control, point-cloud processing and advanced terrain visualization into interpretation-ready cultural-heritage data, while preserving the distinction between detected evidence, potential archaeology and modern features.
