- I wanted to highlight an important comment on last week’s “intensity” blog post.
- Jarlath O’Neil-Dunne from the UVM Spatial Analysis Lab is finding intensity to be a valuable attribute.
- In high contrast regions LiDAR intensity can provide important clues for land use mapping.
I received 2 important comments about last week’s post on intensity. I would like to make everyone aware of the information provided by one of In the Scan’s early supporters, Jarlath O’Neil-Dunne. Jarlath is a geospatial analyst at the University of Vermont’s Spatial Analysis Laboratory. He has been providing me with the real world experience and insight that I lack, so I want to thank Jarlath for his support.
As he pointed out, intensity has proven to be a valuable LiDAR attribute, particularly for impervious surface mapping, when used in a high contrast situation such as in the figure below. This is from a post to the lab’s blog where Jarlath explains their procedure in more detail.
They have been using a data fusion approach combining LiDAR data with CIR imagery and Definiens/eCognition software suite. I discussed the power of this software in one of my first blogs. He also notes the use of QT Modeler, another software package that seems to be showing up more frequently.
Thanks for the comments, and please keep them coming.
