Elevation data outside selected area

Hi

Can you tell me what is happing here.

I created a map catalog of 4 las files download from Queensland Government ( which I have done a thousand times). Created boundary area feature selected it then attempted to create an elevation grid.

I have never seen this happen when I grid lidar before. Why are there points outside the crop area?. The below is from ver21.1. I also tried in ver 22.1 and had the same result

Regards

Richard Saunders

    Hello Richard,

    That does not seem right. I suggest that you contact Blue Marble Support directly via email (geohelp@bluemarblegeo.com) to address this issue. Please included a detailed description of your workflow, including the screen captures you posted here, and sample data (catalog file, lidar data, etc.) that can be used to reproduce the problem. Thank you.

    Cheers,
    Bob
