ForestScanner can acquire 3D point clouds using LiDAR-equipped iPhone 12 Pro, iPhone 12 Pro Max, iPad Pro (2nd generation) 11-inch display or iPad Pro (4th generation) 12.9-inch display The 3D point cloud can be acquired using an iPhone 12 Pro, iPhone 12 Pro Max, iPad Pro (2nd generation) with 11-inch display or iPad Pro (4th generation) with 12.9-inch display. When you tap the "+" icon on a tree, you can get the single tree information such as its diameter and latitude. The acquired point cloud and single tree information can be displayed after saving. The following is a summary of ForestScanner's functions. ■Function list ・3D scanner ・Obtain single tree information by tapping. ・Save the acquired point cloud and single tree information. ・Display and edit the list of saved point clouds and single tree information. ・Display and edit the list of saved point clouds and single tree information. ・Select and edit the list of tree species. ・Select and edit a list of tree species. - Create a csv file of the saved list of single tree information.

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)
