LiDAR Lunch and Learn Seminar – GITA

LiDAR Lunch and Learn Seminar

You are invited to a LiDAR Lunch and Learn Seminar presented by the Carolinas GITA Chapter. The seminar is a high level overview of current LiDAR technologies including both aerial and mobile-based systems. The seminar is designed to give the audience a firm understanding of how LiDAR works and potential applications. LiDAR is quickly becoming a valuable tool in the day-to-day operations for utilities, telecommunications, engineering and government agencies. Join us and learn how this technology may be able to drive value and efficiency into your organization. Lunch will be provided.

Remote Sensing for Coastal Management – NOAA CRC

The Coastal Resource Center – CRC has developed a valuable informational website. The CRC is part of the US National Oceanic and Atmospheric Administration – NOAA. As the name implies their focus is on research in the coastal regions where they have established an outstanding track record.

14 Aspects of Checking Quality of LiDAR data

  1. Always look at 100% of the data.
  2. Devise a series of steps that include what your looking for and how to locate the issues
  3. Analysis the data for new error not previously seen (ie. Sensor malfunctions).
  4. Scrutinize Sub contractor data more than in house data
  5. ALWAYS look for calibration errors.
  6. Use a check list based on past projects and continually modify the checklist based on new issues observed.
  7. Always check for accuracy on all LiDAR data sets
  8. Check the data based on the project requirements ( different projects have different specifications).
  9. Complete coverage of delivery area
  10. Correct LAS version
  11. Accuracy of classes used
  12. Removal of artifacts to meet specifications
  13. Removal of Buildings and vegetation to meet specifcations
  14. No over filtering of bare earth

The 5 most important aspects about processing LiDAR data?

We asked several LiDAR professionals what are the most important aspects of processing LiDAR and the following is a list of their co piled responses:

1. Quality GPS base staion data

2. Tight calibration lines

3. Flightlines of an apprioriate length to prevent IMU drift

4. Complete and concise collection documentation

5. Simple flight plans

6. Project organization

7. Solid Collection

8. Proper and vigorous GPS/IMU processing

9. Rigorous analysis of the terrian and vegetation in development of macros

10. Expereinced editors

11. Conduct S turns on every mission to help IMU find itself after long straight lines

12. Properly collected Data

13. Full coverage checks on every program.

14.  Good QA /QC

The 5 most important aspects of A LiDAR collection?

Several LiDAR professional were asked to list the five  most important aspects of LiDAR collection. This is what they said in no certain order.

1. Well organized field collection plan

2. Trained Field Staff

3. Accurate Logs/data organization/ Organized field documentation

4. Prompt problem reporting

5.Virgous review of the collection area to account for terrian/elevation issues

6.  Good Ground GPS collection and use of high accuracy benchmarks

7.  Avoid flying in adverse weather conditions

8. Always use two Base stations on every mission

9.  Complete field verification of collected data

10.  Network Survey

11. Proper collection of calibration flight lines

12. Colleciton of  S turns

13. Baseline distances based on accuracy requirements.

14. Collection of ground verification data
