Description

Lidar is a remote sensing technique that uses laser light to detect, range, or identify remote objects based on light reflected by the object or emitted through it subsequent fluorescence. Airborne ranging lidar is now being applied in coastal environments to produce accurate, cost-efficient elevation datasets with high data density. The USGS in cooperation with NASA and NPS is using airborne lidar to measure the submerged topography of the Dry Tortugas reef tract and Subaerail topography of land features; secondarily, the data will be assessed for its potential in terms of benthic characterization. Elevation measurements were collected over Dry Tortugas National Park using the NASA Experimental Advanced Airborne Research Lidar (EAARL), a pulsed laser ranging system mounted onboard an aircraft to measure subaerial and submarine coastal topography. With the NASA EAARL lidar system, submarine data is generally acquired to a maximum of approximately 1.5 secchi depths (a measure of water clarity). The system uses a high frequency laser beam directed at the earth's surface through an opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The Experimental Advanced Airborne Research Lidar, developed by the National Aeronautics and Space Administration (NASA) Wallops Flight Facility (WFF) in Virginia, measures ground elevation with a vertical resolution of roughly 15 centimeters. A sampling rate of up to 3 kHz results in an extremely dense spatial elevation data set. For more information on Lidar science and the Experimental Advanced Airborne Research Lidar (EAARL) system and surveys, see http://ngom.usgs.gov/dsp/overview/index.php and http://ngom.usgs.gov/dsp/tech/eaarl/index.php .

Description

Development of the CESI focal plane and optics technology will lead to miniaturized hyperspectral and SWIR-band spectral imaging instrumentation compatible with CubeSat and other nanosat platforms. The project will implement the technology by developing a CubeSat-compatible SEMM instrument for global mapping of atmospheric methane concentrations. Specific Phase I technical objectives include: - Perform a trade study comparing the performance potential of alternate concepts for a miniaturized spectrometer with respect to the methane mapping mission. - Demonstrate that the image of a scene collected through an interferometer is a product of the scene radiance pattern with the interferogram. - Build a laboratory prototype and demonstrate enhanced detection of a multi-line molecular absorption band. - Test novel detector devises suitable for high-gain, low-noise SWIR imaging in a nanosat setting. - Develop the instrument architecture for SEMM and validate the concept analytically by a radiometric model. - Design the high sensitivity, low-noise SWIR focal plane for SEMM. The CESI project is undertaken by Wavefront LLC with the Space Dynamics Lab (SDL) collaborating as the research institution. The key personnel are the Project Manager and the Principle Investigator (from Wavefront) and the scientists (from SDL). The duration of Phase I is 12 months. During Phase II, SDL will prototype the complete CESI instrument incorporating Wavefront's novel high-sensitivity focal plane and readout over 24-month duration.

Description

The innovations proposed are twofold: 1) a robust unstructured mesh movement method able to handle isotropic (Euler), anisotropic (viscous), mixed element (hybrid) and generalized polyhedral unstructured grids for CFD applications, particularly, CFD-based design optimization, and 2) a robust method to automatically insert high quality anisotropic prismatic (viscous boundary layer) cells into any existing CFD mesh. All objectives in Phase I were met and all tasks were completed as proposed. The methods worked very well for both 2D and 3D geometries, for tetrahedral, hexahedral, and general polyhedral element types, and for the simple viscous meshes. In Phase II, we will extend the software into a general purpose package for use by NASA, other Government agencies, and commercial customers. We will implement our 3D viscous mesh generation method including a general solution-adaptive meshing capability. We will develop the software necessary to compute sensitivity derivatives of the mesh operations. Two important software design goals for our final Phase II software are ease-of-use and convenient access to its functionality. We will develop two types of user interfaces: graphical access (for the end-user) and programming access (for integration with flow solvers). We will assemble all of the methods developed in Phase II into a single, coherent, design-oriented, product-version code with extensive focus on incorporating a parallel processing capability into the software. The verification & validation plan will follow the industry-standard approach now used by commercial software houses and will include an extensive set of NASA-relevant test cases. The software will be documented and delivered to NASA. The Phase II software has significant potential for commercialization and sales in the non-Government sector.

Description

Pulley Ridge is a series of drowned barrier islands that extends almost 200 km in 60-100 m water depths. This drowned ridge is located on the Florida Platform in the southeastern Gulf of Mexico about 250 km west of Cape Sable, Florida. This barrier island chain formed during the initial stage of the Holocene marine transgression. These islands were then submerged and left abandoned near the outer edge of the Florida Platform. The southern portion of Pulley Ridge hosts zooxanthellate scleractinian corals, green, red and brown macro algae, and a mix of deep and typically shallow-water tropical fishes. This reef community is in unusually deep water, and its extent and the controls on its distribution were unknown. To address these questions scientists from the U.S. Geological Survey Coastal and Marine Geology Program in cooperation with scientists from the University of South Florida Department of Marine Sciences have completed a detailed mapping of the southernmost 35 km of Pulley Ridge. The area was mapped using multibeam bathymetry, sidescan-sonar imagery, and high-resolution seismic-reflection profiling to define the geologic framework on which the reef is established. Submersible dives, remotely operated vehicle (ROV) transects, and transects of bottom photographs and video were collected to identify the corals and to map their distribution. This extensive suite of data has been compiled and preliminary analysis of the data suggests that the reefs are not tied to the ridge system, but instead are more broadly distributed. Whether reef distribution is controlled by oceanographic conditions or by subtle differences in the substrate that overlies the barrier island system is unclear, and are topics of continued research.

NAL Research Corporation proposes to develop a small, light-weight, low-cost transceivers capable of establishing satellite communications links for telemetry and control during the launch and ascent stages of flight. The proposed transceiver will offer continuous and truly global coverage. When data are sent from a launch vehicle, the signals are received immediately by one of the LEO satellites and relayed in real-time to command and control center via either Public Switched Telephone Network/Public Data Networks (PSTN/PDN), directly to another transceiver, through the Internet or through a direct IP address. The entire process can take a fraction of a second. This will provide electronic global access to airborne vehicles from any place.

Description

The Unpublished Digital Geologic Map of the Chisos Mountains, Texas is composed of GIS data layers complete with ArcMap 9.3 layer (.LYR) files, two ancillary GIS tables, a Map PDF document with ancillary map text, figures and tables, a FGDC metadata record and a 9.3 ArcMap (.MXD) Document that displays the digital map in 9.3 ArcGIS. These data formats also fully represent all of the features present on a GRI digital map, as well as containing related ancillary information GIS data tables. The data is also available as a 2.2 KMZ/KML file for use in Google Earth. Google Earth software is available for free at: http://www.google.com/earth/index.html. Users are encouraged to only use the Google Earth data for basic visualization, and to use the GIS data for any type of data analysis or investigation. The data were completed as a component of the Geologic Resources Inventory (GRI) program, a National Park Service (NPS) Inventory and Monitoring (I&M) Division funded program that is administered by the NPS Geologic Resources Division (GRD). Source geologic maps and data used to complete this GRI digital dataset were provided by the following: U.S. Geological Survey. Detailed information concerning the sources used and their contribution the GRI product are listed in the Source Citation section(s) of this metadata record (cmtn_metadata_faq.html; available at http://nrdata.nps.gov/geology/gri_data/gis/bibe/cmtn_metadata_faq.html). Users of this data are cautioned about the locational accuracy of features within this dataset. Based on the source map scale of 1:50,000 and United States National Map Accuracy Standards features are within (horizontally) 25.4 meters or 83 feet of their actual location as presented by this dataset. Users of this data should thus not assume the location of features is exactly where they are portrayed in Google Earth, ArcGIS or other software used to display this dataset. All GIS and ancillary tables were produced as per the NPS GRI Geology-GIS Geodatabase Data Model v. 2.1. (available at: http://science.nature.nps.gov/im/inventory/geology/GeologyGISDataModel.cfm). The GIS data is available as a 9.3 personal geodatabase (cmtn_geology.mdb), and as shapefile (.SHP) and DBASEIV (.DBF) table files. The GIS data projection is NAD83, UTM Zone 13N, however, for the KML/KMZ format the data is projected upon export to WGS84 Geographic, the native coordinate system used by Google Earth. The data is within the area of interest of Big Bend National Park.

Description

The ultimate goal of the SOAR program is to develop robust hardware and algorithms for low light, passive terrain sensing. The SOAR system will provide NASA with a solution for real-time obstacle avoidance for large and small unmanned air platforms. During Phase-I, we will collect images with all of the leading low-light camera technologies. The image data will be used to derive, test, and enhance a passive terrain sensing algorithm based-on state-of-the-art, visual odometry and dense stereo algorithms. At the end of Phase-I, we will recommend the optimal hardware, algorithm, and computing platform for full prototype development during Phase-II. The factors used to make the recommendation include cost, range accuracy, size, power consumption, algorithm execution time, etc.

Description

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the State Plane projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12000.
