Drone-mounted LiDAR is helping archaeologists map parts of the 1943 Battle of New Georgia, where jungle cover obscures the terrain and the circumstances behind U.S. losses remain unresolved. In a September 2026 announcement, Binghamton University researchers described surveying one square kilometer on Dragon’s Peninsula with 25 drone flights, then checking landscape clues on foot. The work has identified places for further investigation; the announcement does not say that the team found graves or the remains of missing servicemen.
Why the New Georgia battlefield is difficult to reconstruct
New Georgia, in the Solomon Islands, was strategically important because of a Japanese airstrip near Munda and a supply route through Bairoko Harbor. In July 1943, U.S. Marines sought to cut that supply line. Marine Raiders attacked Bairoko Harbor but withdrew under heavy fire to Enogai Inlet, where they established defensive positions. U.S. forces later took the airfield, and Japanese forces began withdrawing from the island in late August.

The Binghamton University project focuses on the gap between accounts of the fighting and what can still be read in the landscape. The university’s September 24, 2026 announcement says more than 23 U.S. servicemen remain unaccounted for. The researchers are trying to understand where the fighting occurred and how reported losses may relate to physical evidence—not claiming that the missing have been located.
How the researchers combined records, LiDAR and field archaeology
Reconstructing movements from documents
Before going to the island, researchers Carl Lipo and Thomas Pingel reviewed commanders’ after-action reports, hand-drawn maps and other accounts of the July battles. They used AI to organize primary, secondary and tertiary sources, digitized historical maps, and reconstructed daily unit positions to build a probability map of patrol routes. The announcement gives no validation metrics for the AI work, so it is best understood as an organizational and reconstruction aid—not an independent authority on what happened.

Mapping a jungle-covered area
On Dragon’s Peninsula, described by the university as the site of one of the campaign’s largest battles, the team surveyed one square kilometer. A drone supplied by local partner Kahuto Pacific made 25 data-collection flights. Archaeologists from the International Archaeology Research Institute, Inc. then investigated findings on foot.
LiDAR sends laser pulses toward the ground and uses their returns to create three-dimensional topographic data. A systematic flight pattern can reveal ground features beneath dense vegetation. The team looked for trails, foxholes, machine-gun positions and other signs of human activity. The university reported terrain features and material traces including barbed wire, Japanese food containers and cans, gas masks, grenades, mortars and large bomb craters.

- Please note: The MID‑360 has been discontinued and is now replaced by the new MID‑360S. The MID‑360S is functionally identical to the original MID‑360, with the only change being the position of the LOGO; core performance specifications remain unchanged.

- 【Superior Range & Accuracy】 Offers a range of ≥38m under 10% reflectivity conditions (standard range acceptance). Distance measurement system error is as low as ±2cm@10m. Equipped with a built-in high-precision IMU (ICM40609) for stable and reliable data output.
- 【High-Reliability Design】 Rated IP67 for dust and water resistance. Operates in a wide temperature range from -20°C to 55°C. Fanless design, compact and robust construction (~265g), suitable for outdoor and harsh industrial environments.
- 【High-Efficiency Data & Synchronization】 High data rate of 200,000 points/second and a point cloud frame rate of 10Hz. Supports multiple high-precision time synchronization methods: IEEE 1588-2008 (PTP v2) and GPS (PPS+UTC), facilitating multi-sensor fusion.
The announcement does not identify the drone model or LiDAR sensor, or report point density or survey accuracy. The flight count and survey area therefore describe the New Georgia work, but do not provide enough technical information to reproduce or independently assess its mapping precision.

In this case, the puzzle is how to reconcile battle narratives and reported losses with physical evidence on a landscape now largely covered by jungle. One example shows why checking documents against terrain matters: a written account described four parallel ridges, but LiDAR showed one large ridge. The researchers traced the discrepancy to a later account that had confused the number of defensive lines with a geological feature.

That correction illustrates how terrain data can test a historical description. It does not mean LiDAR or AI can independently establish exactly what happened, identify every burial location, or explain each loss. The researchers said they were continuing to analyze possible burial locations and lines of fire; the battlefield’s full extent remains unknown.
What happens next in the search
The mapped features are leads for continued fieldwork. Researchers identified locations for possible magnetometry surveys or excavation, and described further exploration of defensive positions to the east, west and south. The university announcement documents a research partnership with the U.S. Defense POW/MIA Accounting Agency, but does not detail community consultation, permissions or decisions about future excavation.
The work takes place in Solomon Islands communities and on a landscape that still bears traces of war. The reported use of a drone supplied by a local partner is part of the project’s account; the announcement does not establish what role local communities have in decisions about subsequent investigation.
How other WWII LiDAR studies compare
Other battlefield surveys show how LiDAR can be combined with higher-resolution mapping or ground checks, but they concern different campaigns and datasets. Their technical figures should not be attributed to New Georgia.

| Study | Place and campaign | Reported method or result | How to interpret it |
|---|---|---|---|
| New Georgia project, Binghamton University, 2026 | Dragon’s Peninsula, Solomon Islands; fighting in 1943 | One-square-kilometer survey area and 25 drone flights; sensor, point density and accuracy not stated in the announcement. | Reported terrain and material clues guide further investigation; no discovery of graves or remains is reported. |
| Stichelbaut et al., Antiquity, 2023 | Forested Ardennes, Belgium; Battle of the Bulge, 1944–45 | Drone-mounted 1-meter-resolution LiDAR combined with very-high-resolution simultaneous localization and mapping (SLAM); more than 940 features reported in the paper’s abstract. | The authors’ formal figure is more than 940 identified features, many later visited and confirmed; it is a separate European battlefield study. |
| Adam, Storch and Rass, Antiquity, 2022 | Kall Trail, Hürtgen Forest, Germany | The study reports 100 points per square meter for UAV LiDAR and approximately 10 points per square meter for the cited airborne laser data in the paper. | These are Kall Trail dataset figures, not specifications for the New Georgia survey. |
National Geographic described the Battle of the Bulge work as finding more than 1,000 previously unknown features, including dugouts, shelters, craters, artillery positions, foxholes and trenches across a larger mapped area. That journalistic account is a different description of the same study, not a New Georgia result; see its 2023 report.
