SlashScan is an iOS application for real-time estimation and mapping of forest slash-pile volumes using the built-in LiDAR sensor of iPad Pro devices. Developed through research at Oregon State University’s College of Forestry, SlashScan provides an accurate, portable, and field-ready solution for forestry operations, biomass inventory, and research applications. ■ Key Features Real-time 3D Scanning: Capture detailed point clouds of slash piles using the iPad’s LiDAR sensor. Automated Mesh Reconstruction: Generate precise 3D models optimized for irregular pile geometries. Accurate Volume Estimation: Instantly compute pile volume and export results for analysis or reporting. Integrated Mapping: GNSS tagging and satellite map view allow users to visualize and manage multiple pile locations. Offline Capability: All processing—scanning, reconstruction, and volume computation—occurs locally, enabling use in remote forest sites without internet access. ■ Applications SlashScan supports operational and research applications such as: Forest biomass and slash-pile inventory Post-harvest residue and fuel-load management Validation of UAV-LiDAR and photogrammetric surveys Educational demonstrations in forest engineering and remote sensing ■ Supported Devices SlashScan requires a LiDAR-equipped iOS device. Fully Supported Models: iPhone 12-17 Pro iPhone 12-17 Pro Max iPad Pro 13-inch (M4) iPad Pro 12.9-inch (5th & 6th Gen, M1/M2) iPad Pro 11-inch (3rd & 4th Gen, M1/M2)
