Knap XP
Knap XP™
The Knap XP™ is an advanced mobile mapping system that allows you to gather detailed precise data. The system is adaptable for use on BackPack or UAV.
Product Overview
The Knap XP™ is a LiDAR system designed specifically for use in forest environments. State-of-the-art sensors capture detailed data with precision and efficiency in backpack or Unmanned Aerial Vehicle (UAV, or drone) mode.
A wireless web app makes the XP™ easy to operate, while two rechargeable batteries help maximize data collection efforts. Our integrated processing pipeline generates point clouds and extracts tree metrics in a single workflow.

How the Knap™ Works
Inertial navigation on the Knap XP™ provides real-time acceleration and rotation augmented with GNSS position. In direct georeferencing mode, this navigation data is post-processed and further enhanced using LiDAR point data. Onboard processing also enables SLAM mode, where a precise trajectory is generated in real-time without the need for GNSS.
After point cloud generation, individual trees are segmented, and relevant metrics can be extracted on a per-tree basis. This workflow allows a user to collect data for acres of inventory purposes in just minutes.
Data Capture
The Knap XP™ captures all raw data internally for complete mission data records. Capture and organize multi-acquisition missions via web-based interface.
Tree metrics that can be extracted from point cloud:
- Location
- Height
- Diameter
- Volume
- Bifurcation
- Board feet
- Inch-level performance in position and metrics
