SlashScan vs NoiseBook

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)

NoiseBook turns your phone into a simple, honest noise level meter. Start a measurement, watch the gauge move, and keep a logbook of the places and moments that were too loud, or pleasantly quiet. MEASURE IN SECONDS Tap start and NoiseBook samples the microphone once per second. You see the live level on an analog gauge or a clean digital readout, plus minimum, average and maximum for the whole session and a rolling 30 second chart. UNDERSTAND WHAT YOU HEAR Every reading is put into context with everyday reference points: a quiet room, a normal conversation, busy traffic, a jet engine. A reference table lists them all so a number like 65 dB actually means something. KEEP A LOGBOOK Save a measurement with a title and, if you like, your location. The logbook shows every entry with date, level and place, filtered by the last hour, the last 24 hours or the last week. SEE IT ON A MAP (PREMIUM) Premium unlocks the noise map: every saved measurement becomes a colour coded marker, green for quiet, yellow for moderate, red for loud. Frame your neighbourhood, your commute or your holiday and spot the loud corners at a glance. Premium also includes the full 7 day history filter. PRIVACY FIRST Everything is stored on your device. There is no account and no upload of your measurements. Crash reports and anonymous usage statistics are off until you switch them on, and you can turn them off again at any time in Settings. GOOD TO KNOW Phone microphones are not certified measuring instruments. NoiseBook gives you consistent, comparable readings on your device, not a legally binding measurement.
