Clouds - Not the Fluffy Kind

Following up on the "Question of the Day" post, I wanted to share a video that was produced of the I-110 collection in Baton Rouge.  The video was part of a presentation given earlier this week at the National States Geographic Information Council Mid-Year Conference in Annapolis, Maryland.

The collection consisted of 27 different approaches to the interchange and took about one and a half hours.  The dense collection of points is commonly referred to as a Point Cloud - Wikipedia has a limited definition.  The cloud shown in the video is composed of 491 million points.


  1. Very cool, thanks for sharing.

    How long does the post-processing take for a data set that large?

  2. The point cloud presented in the video was processed the next day. We collected the interchange on a Friday afternoon. By Saturday afternoon, I was working with the processed point cloud. The dataset isn't as large or complex as other collections we've performed.
