      How to Use CORS Data to Process LiDAR in ROCK Desktop

      How to Use CORS Data for Processing LiDAR in ROCK Desktop | Step-by-Step Guide

      If you're using a CORS (Continuously Operating Reference Station) to process your LiDAR data in ROCK Desktop, follow these steps to ensure accuracy and optimal performance.

      Steps to Process LiDAR Data with CORS in ROCK Desktop

      1. Base Station Proximity

        • Ensure the CORS station is no more than 15 km from your project site. Beyond this distance, data accuracy may degrade.

      2. Verify RINEX File Details

        • Confirm that your RINEX file includes GPS, GLONASS, BeiDou, and Galileo constellations.
        • Ensure the data was captured at a 1-second interval for maximum precision.

      3. Check RINEX Coordinate System

        • ROCK Desktop automatically reads the base station location from the RINEX file header.
        • Verify that the coordinates are in WGS84 format. If not, retrieve the correct WGS84 coordinates from the CORS station's specifications and enter them manually in the advanced menu.

      4. Proceed with LiDAR Data Processing

        • After verifying the above details, proceed with processing your LiDAR data in ROCK Desktop as usual.
        • The output LAS point cloud file will be int UTM projection and ellipsoidal height.

      “When using the CORS station, accuracy depends significantly on its proximity and the quality of the RINEX file.”
