Automated Feature Detection in LiDAR Data
The ISGS hosted a meeting to share a common overview of available LiDAR
data for Illinois and introduce Eric Shaffer's group from the University
of Illinois at Urbana-Champaign (UIUC) Computational Science and
Engineering. About 20 people attended from ISGS, Illinois Natural History
Survey, Illinois State Archaeological Survey, UIUC, US Army Corps of
Engineers, and Natural Resources Conservation Service. Attendees discussed
potential LiDAR applications across a wide array of specialty subjects.
The meeting received considerable positive feedback and fostered the
beginning of a community of research scientists interested in
interdisciplinary collaboration. Scientists expressed interest in LiDAR
1. Forestry and plant communities
2. Water management and nutrient runoff
3. Identification of abandoned quarries
4. Glacial landscapes and landforms
5. Engineering geology for soils and slope stability
6. Detection of archaeological features
7. Protection of cemeteries and archaeological sites.

ISGS Sediment Lab director Hue-Hwa Hwang performs wet sieving on a sample to separate sand from silt and clay. It is part of sample preparation procedures for SediGraph® particle size analysis.
Sediment Laboratory Offers Particle Size Services
The ISGS Sediment Laboratory offers particle size services for scientific and engineering samples. The lab currently provides hydrometer, pipette, and sieve analyses that cover particle size range from < 2 micron to > 3 inches. Since fall of 2011, a partnership with the Illinois State Water Survey Sediment Laboratory now provides more size break point analyses for fines between 62 and 2 microns with the SediGraph® particle size analyzer. Additional new services can be discussed through research collaboration. Contact: Hue-Hwa Hwang
