The GPS Time Slider tool within ROCK Cloud is a great way to check the data quality of your LiDAR data.
Overview
The GPS time slider is a powerful feature in ROCK Cloud that allows you to examine your dataset in detail. By adjusting the slider, you can isolate data from different flight lines and check for consistency and quality. Here's how you can use it effectively:
Step-by-Step Guide
- Open Your Data Set: Start by opening your data set in ROCK Cloud.
- Change the Material to Intensity Gradient or Intensity: Examine the Intensity Gradient or Intensity view of your data, adjusting the range as needed to highlight certain features.
- Adjust the GPS Time Slider:
- Begin at the far right, representing the end of your dataset's GPS time.
- Slowly move the slider to the center and then to the left, sequentially removing data from each flight line.
- Check for Overlap:
- Zoom in on areas with overlap between flight lines.
- Look for alignment and consistency in features like parking lines.
- Investigate Data Quality:
- If the features fill in seamlessly without offsets, this indicates high-quality data.
- Offsets may suggest issues like poor base data or the need for calibration.
- Zoom down to ground level to inspect the distribution and characteristics of the LiDAR data on the surface.
- Variations in the distribution of LiDAR data on the ground surface in areas of flight line overlaps can indicate issues with data quality that require further inspection.
By using the GPS time slider, you can ensure that your data is accurate and reliable. This tool helps you identify potential issues and verify the quality of your LiDAR captures. For any further questions or comments, feel free to reach out to us at support@rockrobotic.com.
