Carbon in juniper woodlands

Fri, 2011-10-21 09:23

Woody encroachment into shrub steppe and grassland ecosystems is a global phenomenon.  Juniper encroachment is one of the most prominent changes occurring in rangelands of western North America.  The spatial extent of pinyon-juniper woodlands, the third most common vegetation type in the USA, is documented to have increased by an order of magnitude since the mid-19th century.

Mapping spider habitat with LiDAR

Wed, 2011-06-15 07:36

University of Idaho professors Lee Vierling and Kerri Vierling collaborated with a team of German scientists to study ecosystems using remotely sensed laser data. The research team used LiDAR data collected from aircraft to create 3-D pictures of the different forest layers in Germany’s Bavarian Forest National Park. By combining LiDAR data with extensive field data about spiders and other information about an area’s vegetation, rainfall patterns and temperature, researchers can get a detailed picture about the habitat characteristics important to a healthy spider population.

LiDAR helps discover new fault

Wed, 2011-06-15 07:14

While looking at a highly detailed new topographic image of Idaho’s Sawtooth Range, Idaho State University geosciences professor Glenn Thackray had an "eureka moment" when he discovered a previously unknown active earthquake fault about 65 miles, as the crow flies, from Boise. ISU researchers estimate the fault has been active twice in the last 10,000 years, about 4,100 and 7,000 years ago.

New LiDAR Acquisition by FEMA

Mon, 2011-06-13 08:07

June 8 - June 17, Aerometric, a contractor hired by the Federal Emergency Management Agency (FEMA) Region X, will be flying an aircraft-mounted Light Detection and Ranging (LiDAR) laser sensor to map 875 square miles of Idaho floodplain. This LiDAR data will be processed to make enhanced digital topographic maps. IDWR prefers to use LiDAR data for mapping Idaho floodplains because LiDAR is a floodplain mapping best practice for superb accuracy, resolution, precision, cost effectiveness and utility.

Woodpecker Habitat from LiDAR

Sat, 2011-06-11 12:11

Researchers from University of Idaho have proved they can predict the presence of the Pileated Woodpecker in a coniferous forest in northwestern Idaho, using small footprint airborne lidar, large footprint satellite lidar from the Geoscience Laser Altimeter System (GLAS), and field survey data. The results were presented at the annual meeting of American Geophysical Union (AGU) in December, 2010.

LiDAR Processing Workshops

Idaho State University, Boise Center of Aerospace Laboratory (BCAL) organized workshops on LiDAR processing during Intermountain GIS Conference in Pocatello, ID (March, 2011) and International Symposium for Remote Sensing of the Environment in Sydney, Australia (April, 2011). A similar workshop was previously organized in August, 2010 during NSF EPSCoR Annual Meeting in Boise, ID. A significant part of the workshop was focused on processing LiDAR data to create derived products useful for watershed modeling.

FEMA Standards for LiDAR

Beginning in Fiscal Year (FY) 2010, Federal Emergency Management Agency (FEMA) initiated a five-year program for Risk Mapping, Assessment, and Planning (Risk MAP). FEMA’s vision for the Risk MAP program is to deliver quality data that increases public awareness and leads to mitigation actions that reduce risk to life and property. To achieve this vision, FEMA will transform its traditional flood identification and mapping efforts into a more integrated process of accurately identifying, assessing, communicating, planning for, and mitigating flood risks.

3D LiDAR Visualization

Tue, 2011-06-07 15:03

Idaho State University, Boise Center Aerospace Laboratory (BCAL) is developing new methods to visualize and interact with hyperspectral and LiDAR remote sensing data. As these data are becoming increasing complex, new methods for fusing and interacting with the data are necessary for leveraging their multidimensionality. With a new immersive
3D system resulting from a collaboration between Idaho Universities and the Idaho National Laboratory (INL), scientists can explore multiple dimensions of data that, until now, could only be viewed two dimensionally.
