Introduction to Pre-Processing

Pre-Processing is a custom 'raw sensor data' processing platform enabling users to upload raw GNSS/INS files, GNSS base station data and raw Point Cloud formats to produce a post-processed trajectory and calibrated point cloud. This enables a seamless workflow into Pointerra viewing and analytics.

Pre-Processing is currently supported for airborne (Manned/Unmanned) Trimble/Applanix GNSS/INS systems and Riegl laser sensors.

Pre-Processing incorporates:

  1. Sensor Configuration - store GNSS/INS and Raw Laser calibration parameters for repeatable use in our processing workflows.
  2. Upload - raw sensor file input, base station coordinates and antenna information, coordinate system definition for processing.
  3. Processing - post-processed GNSS/INS solution incorporating base station static data or Trimble PP-RTX service, conversion of raw Riegl laser files to industry standard LAZ format, calibration and alignment of LAZ files.
  4. Quality Control - full logging of processing workflows and quality control documents for review in the browser.
  5. Pointerra Viewer - ability to build a Pointerra point cloud to our Viewer directly from the Pre-Processing workflow.
