Read full description

LogStackLIDAR lets you easily measure the wood volume of timber stacks - without you having to set any references with measurement sticks or tape. Instead, the built-in LiDAR scanner of the Apple Pro device sets an objective scale of the log stack. This makes LogStackLIDAR the most reliable measurement system in the market, securing full transparency in the wood trade. Here’s how it works: 1. Walk along the raw wood stacks while scanning the front (and back surface) with your device. 2. Tap in stack number, quality, fixed log lengths and other unique stack information 3. LogStackLIDAR now produces a complete report with all relevant results, including total stack volume, solid volume and total number of logs. 4. The measured raw wood data can be accessed by all business partners through a secure cloud solution. Please feel free to contact us, if you have any questions regarding the most reliable handheld measuring device for raw wood stacks on the market: https://forestx.se/logstacklidar/#kontakt ***The demo version lets you try measuring, while the full version gives you the high accuracy and full range of data in the report customized for your organization.
