Biome is a mobile app that turns your phone into a powerful field tool for measuring trees. Use Lidar and AI to measure diameter at breast height (DBH), tree height, and identify species. No tape, no clinometer, no manual notes! Designed for smallholders, researchers, and carbon project developers, Biome helps you collect accurate, verifiable field data 10× faster. Features: • Lidar-based DBH and height measurement • Tree segmentation using AI (TreeSeg) • GPS-stamped plot data • Offline mode for remote fieldwork • Export raw measurements for carbon MRV workflows Funded by the U.S. National Science Foundation (NSF). Tested and validated in real reforestation projects. *Requires device with LIDAR sensor (e.g. iPhone 12 Pro+)

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)
