PFM-1 Landmine VNIR Hyperspectral Imaging Dataset (IGARSS 2026)

Dataset Description

This dataset 1 contains Visible and Near-Infrared (VNIR) Hyperspectral Imaging (HSI) data prepared for the IEEE International Geoscience and Remote Sensing Symposium (IGARSS) 2026.

This specific version is a refined subset of the original benchmark dataset 2. While the original release provided full radiance cubes, broad GCP/AeroPoint data, and reference ground spectra of all the targets, this version focuses on a spatially subsetted region containing only PFM-1 landmine targets and includes high-accuracy, pixel-wise binary ground truth masks.

The data was collected over a controlled test field seeded with 143 realistic surrogate landmine and UXO targets (surface, partially buried, and fully buried). Data acquisition was performed using a Headwall Nano-Hyperspec® sensor mounted on a multi-sensor UAV platform flown at an altitude of ~20.6 m 2.

For more details regarding data acquistion and preprocessing, go to the original paper 2.

• Sensor: [Headwall Nano-Hyperspec®]
• Spectral Range: [398–1002 nm]
• Number of Bands: [270 bands]
• Approximate GSD: [Approx. 1.29 cm]
