LiDAR Dataset Comparison

Thanks for sharing your video comparing LiDAR datasets of the same site! It was very informative to see the different ways that the datasets could be compared and contrasted.

I was particularly interested in the section of your video where you compared the datasets for elevation accuracy. You showed how the two datasets differed in terms of their vertical and horizontal accuracy, as well as their point density. This was very helpful in understanding the strengths and weaknesses of each dataset.

I also appreciated the way that you discussed the implications of the dataset comparison for different applications. For example, you explained how the vertical accuracy of the datasets would impact their suitability for tasks such as terrain modeling and change detection.

Overall, I found your video to be very informative and well-produced.

Thanks,
Matt

Thanks for the review, well done. Also, I'm enjoying your content on your YT channel.

Great video, I've already shared a link with my customers to share with their engineers. On a recent job one customer asked me for 2mm accuracy. I quoted: "as accurately as practically achievable". We've used an SX12 for control scans, with scans taken from least squared adjusted control points (also levelled). Haven't quite finished it yet.

On a recent job one customer asked me for 2mm accuracy.

"Accuracy for all survey points shall be 0.01 foot."

"Points must be surveyed to 0.01 feet."

"Accuracy for all surveys shall meet minimum requirements of 1/64" for location and 5 seconds for angle."

"Surveys shall be measured to one hundredth of a foot and one arc-second."

Funny stuff.
