Description
A characterization of the data, including its intended use and limitations.
Abstract:
The United States Geological Survey (USGS) Center for Coastal and Watershed Studies, the National Aeronautics and Space Administration (NASA), United States Bureau of Reclamation (Reclamation), Idaho Department of Water Resources (IDWR) and a consortium of local city, county agencies and private entities (see supplemental information) are using airborne LiDAR to measure the submerged topography of the Boise River.  The study area encompasses the 500 year floodplain from Lucky Peak Reservoir to the confluence of the Boise River and the Snake River.  Elevation measurements were collected in March of 2007 using the NASA Experimental Advanced Airborne Research LiDAR (EAARL).  Initially developed by NASA and Wallops Flight Facility (WFF) in Virginia and now administered by the USGS Coastal and Marine Geology Program, EAARL measures ground elevation with a vertical accuracy of roughly 15 centimeters.  The data were processed by IDWR using the Airborne LiDAR Processing System (ALPS), a multi-tiered processing system developed by a USGS/NASA collaborative project for the use of subaerial and submarine LiDAR.  The output from this processing is 2 meter resolution raster data that can be easily ingested into a Geographic Information System (GIS).  The data were organized as 2 km by 2 km data tiles in ERDAS imagine format.  Point data information is also available for first return, bare earth, submerged topography and a submerged topography/bare earth combination. These tiles are created for visual interpretation and regional quantitative analysis. The data are in UTM Zone 11 meters, NAD83, NAVD88 (Geoid 03 model).  At the same time that the Boise River LiDAR data were collected, USGS collected cross sectional data using survey grade GPS at three separate sections along the river - upper, middle and lower.  These ground observations were then used to quality check the LiDAR data and to provide a vertical accuracy assessment.  The results of the quality assessment will be available by the end of December, 2009.  This metadata document will be updated at that time.
Purpose:
One objective of this research is the development of techniques for the surveying of bare earth and submerged topography for habitat mapping, ecological monitoring, change detection, and event assessment (e.g., flood events) in riverine environments. The EAARL sensor has the potential to make significant contributions in this realm for measuring the elevation of shallow water bed elevation and conducting cross-environment surveys. High spatial resolution and low costs were found to be key factors in providing accurate and affordable data to managers.
Supplemental information:
Other participating agencies in this project include, Ada County Highway District, Ada County, City of Boise, City of Eagle, City of Star, U.S. Corps of Engineers, Eagle Sewer District, Flood Control Dist. 10, Flood Control District 11, Garden City, Harris Ranch, Idaho Rivers United, and Trout Unlimited. Light Detection and Ranging (LiDAR) is a remote sensing technique that uses laser light to detect, range, or identify remote objects based on light reflected by the object. Airborne LiDAR is now being applied in coastal and riverine environments to produce accurate, cost-efficient elevation datasets with high data density.  Raw LiDAR data is not in a format that is generally usable by resource managers and scientists for scientific analysis.  Specialized processing algorithms are used to convert raw waveform LiDAR data acquired by the EAARL to geo-referenced spot (x,y,z) returns for submarine topography.  Metadata files include the standard FGDC format.

Metadata Standards
Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.
Standard name: FGDC Content Standards for Digital Geospatial Metadata
Standard version: FGDC-STD-001-1998
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.0
Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.
