Description

Hydrographic and Impairment Statistics (HIS) is a National Park Service (NPS) Water Resources Division (WRD) project established to track certain goals created in response to the Government Performance and Results Act of 1993 (GPRA). One water resources management goal established by the Department of the Interior under GRPA requires NPS to track the percent of its managed surface waters that are meeting Clean Water Act (CWA) water quality standards. This goal requires an accurate inventory that spatially quantifies the surface water hydrography that each bureau manages and a procedure to determine and track which waterbodies are or are not meeting water quality standards as outlined by Section 303(d) of the CWA. This project helps meet this DOI GRPA goal by inventorying and monitoring in a geographic information system for the NPS: (1) CWA 303(d) quality impaired waters and causes; and (2) hydrographic statistics based on the United States Geological Survey (USGS) National Hydrography Dataset (NHD). Hydrographic and 303(d) impairment statistics were evaluated based on a combination of 1:24,000 (NHD) and finer scale data (frequently provided by state GIS layers).

Description

This data set consists of digitized water-level elevation contours for the Enid isolated terrace aquifer in northwestern Oklahoma. The Enid isolated terrace aquifer covers approximately 82 square miles and supplies water for irrigation, domestic, municipal, and industrial use for the City of Enid and western Garfield County. The Quaternary-age Enid isolated terrace aquifer is composed of terrace deposits that consist of discontinuous layers of clay, sandy clay, sand, and gravel. The aquifer is unconfined and is bounded by the underlying Permian-age Hennessey Group on the east and the Cedar Hills Sandstone Formation of the Permian-age El Reno Group on the west. Cedar Hills Sandstone Formation fills a channel beneath the thickest section of the Enid isolated terrace aquifer in the midwestern part of the aquifer. The water-level elevation contours were digitized from a photocopy of a paper map in a ground-water modeling thesis and report. The map digitized was published at a scale of 1:62,500 shows that the ground-water elevations in 1973 ranged from about 1,360 feet above sea level at the northwestern edge to about 1,150 feet above sea level at the southeastern edge of the aquifer.

Description

NASA has a need for technologies that will enable them to repair damage to composite structures. Fiber-reinforced polymer composite materials are fast gaining ground as preferred materials for the construction of aircraft and spacecraft. In particular, the use of composites as primary structural materials in several technology-demonstrator front-line aerospace projects worldwide has provided confidence leading to their acceptance as prime materials for aerospace vehicles. Respectively, materials and tools that can provide rapid, permanent or temporary repairs of composite structural damage in a space environment should follow the wide utilization of composites in airspace vehicles. This proposed project will result in the development of a fast cure repair kit for composites (C-kit) that will consist of the basic composite fabric preimpregnated (prepreg) with an ultraviolet (UV) light-curing resin, a dispenser containing UV curable resin with properties close to the basic matrix resin, and a battery-operated portable, efficient single light emitting diode (LED) as the source of UV radiation. The prepreg material, which will be in the form of tape and precut patches, and the resin will be stored separately in protective dispensers. The cure of each layer of repair material will take less than a minute. Surface cleaning materials will also be included in the kit. In this project, IOS will collaborate with a manufacturer devoted specifically to the development of UV cured adhesives for specific high end applications. This work will extend the knowledge and experience previously attained by the IOS/ SGL team in the development of light-curing adhesives for Navy ships corrosion protection and for corrosive barrier restoration in Navy fleet composite materials.

Description

The 2014 cartographic boundary shapefiles are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. A consolidated city is a unit of local government for which the functions of an incorporated place and its county or minor civil division (MCD) have merged. This action results in both the primary incorporated place and the county or MCD continuing to exist as legal entities, even though the county or MCD performs few or no governmental functions and has few or no elected officials. Where this occurs, and where one or more other incorporated places in the county or MCD continue to function as separate governments, even though they have been included in the consolidated government, the primary incorporated place is referred to as a consolidated city. The Census Bureau classifies the separately incorporated places within the consolidated city as place entities and creates a separate place (balance) record for the portion of the consolidated city not within any other place.

Description

High temperature piezoelectric crystal (HTP) sensors are desired for future propulsion component structure health monitoring, operating parameters optimization, turbine engine control and health monitoring, as well as improving performance and maintainability of power production facilities and other rotary combustion engines. Recently discovered high temperature piezoelectrics showed stable piezoelectric properties and high resistivity at temperatures close to its melting point (~ 1500 C) , which is very promising for high temperature sensor applications. The preliminary results showed excellent temperature sening performance at temperature up to 1000 C. Piezoelectric structural sensors on the basis of piezoelectric effect (non-resonant) and impedance measurement (resonant) have been widely demonstrated for pressure, stress, strain, temperature, acceleration, etc. measurements because of their high sensitivity, quick response, low profile, high reliability and low cost. The goal of this program is to develop highly sensitive HTPC based piezoelectric structural sensors for temperature, strain and acceleration measurements at temperatures up to 2000 oF.

Description

This image is a mosaic of Landsat-7 images of the upper Klamath Basin. The original images were obtained from the U.S. Geological Survey Earth Resources Observation and Science Center (EROS). EROS is responsible for archive management and distribution of Landsat data products. The Landsat-7 satellite is part of an ongoing mission to provide quality remote sensing data in support of research and applications activities. The launch of Landsat-7 on April 15, 1999 marks the addition of the latest satellite to the Landsat series. The Landsat-7 satellite carries the Enhanced Thematic Mapper Plus (ETM+) sensor. A mechanical failure of the ETM+ Scan Line Corrector (SLC) occurred on May 31, 2003, with the result that all Landsat 7 scenes acquired from July 14, 2003 to present have been collected in 'SLC-off' mode. More information on the Landsat program can be found online at http://landsat.usgs.gov/.

Description

The new Constellation vehicles, habitats and robots will be highly sensored and generate large amounts of data. For this data to be useful to humans monitoring these systems and to automated algorithms controlling these systems it will need to be converted into more abstract data. This abstracted data will reflect the trends and characteristics of the systems and their environments. Currently this data abstraction process is manual and ad hoc. It is manual in the sense that either humans do the abstraction in their heads or the data abstraction is done by hand-coding computer programs for each data item. It is ad hoc in the sense that each data abstraction is developed on its own with no representation of how it relates to the tasks being performed or to other data abstractions. In this project we propose building a Data Abstraction Architecture (DAA) that allows engineers to design software processes that iteratively convert spacecraft data into higher and higher levels of abstraction. The DAA also formalizes the relationships between data and control and the relationships between the data themselves. The DAA consists of representations for data and data abstractions, a data store, a abstraction architecture processing engine and a development environment. We will evaluate the architecture using three NASA domains: 1) a lunar outpost monitoring and control application; 2) a robotic scientific survey application; and 3) a vehicle procedure execution scenario.

Description

A joint venture involving the National Atlas programs in Canada (Natural Resources Canada), Mexico (Instituto Nacional de Estadística Geografía e Informática), and the United States (U.S. Geological Survey), as well as the North American Commission for Environmental Co-operation, has led to the release (June 2004) of several new products: an updated paper map of North America, and its associated geospatial data sets and their metadata. These data sets are available online from each of the partner countries both for visualization and download. The North American Atlas data are standardized geospatial data sets at 1:10,000,000 scale. A variety of basic data layers (e.g. roads, railroads, populated places, political boundaries, hydrography, bathymetry, sea ice and glaciers) have been integrated so that their relative positions are correct. This collection of data sets forms a base with which other North American thematic data may be integrated. Any data outside of Canada, Mexico, and the United States of America included in the North American Atlas data sets is strictly to complete the context of the data. The North American Atlas - Sea Ice data set shows the approximate extent of marine areas in the Arctic covered by permanent polar ice. The data originated from the Canadian Ice Service and was used in the 1:6,000,000 National Atlas of Canada Reference Map Series. It is represented by polygons showing the average minimum ice limit over a 30 year period, 1969-1999.

Description

This dataset is one of eight datasets produced by this study. Four of the datasets predict the probability of detecting atrazine and(or) desethyl-atrazine (a breakdown product of atrazine) in ground water in Colorado; the other four predict the probability of detecting elevated concentrations of nitrate in ground water in Colorado. The four datasets that predict the probability of atrazine and(or) desethyl-atrazine (atrazine/DEA) are differentiated by whether or not they incorporated atrazine use and whether or not they incorporated hydrogeomorphic regions. The four datasets that predict the probability of elevated concentrations of nitrate are differentiated by whether or not they incorporated fertilizer use and whether or not they incorporated hydrogeomorphic regions. Each of the eight datasets has its own unique strengths and weaknesses. The user is cautioned to read Rupert (2003, Probability of detecting atrazine/desethyl-atrazine and elevated concentrations of nitrate in ground water in Colorado: U.S. Geological Survey Water-Resources Investigations Report 02-4269, 35 p., http://water.usgs.gov/pubs/wri/wri02-4269/) to determine if he(she) is using the most appropriate dataset for his(her) particular needs. This dataset specifically predicts the probability of detecting atrazine/DEA in ground water in Colorado with hydrogeomorphic regions and atrazine use estimates included. The following text was extracted from Rupert (2003). Draft Federal regulations may require that each State develop a State Pesticide Management Plan for the herbicides atrazine, alachlor, metolachlor, and simazine. Maps were developed that the State of Colorado could use to predict the probability of detecting atrazine/DEA in ground water in Colorado. These maps can be incorporated into the State Pesticide Management Plan and can help provide a sound hydrogeologic basis for atrazine management in Colorado. Maps showing the probability of detecting elevated nitrite plus nitrate as nitrogen (nitrate) concentrations in ground water in Colorado also were developed because nitrate is a contaminant of concern in many areas of Colorado. Maps showing the probability of detecting atrazine/DEA at or greater than concentrations of 0.1 microgram per liter and nitrate concentrations in ground water greater than 5 milligrams per liter were developed as follows: (1) Ground-water quality data were overlaid with anthropogenic and hydrogeologic data by using a geographic information system (GIS) to produce a dataset in which each well had corresponding data on atrazine use, fertilizer use, geology, hydrogeomorphic regions, land cover, precipitation, soils, and well construction. These data then were downloaded to a statistical software package for analysis by logistic regression. (2) Relations were observed between ground-water quality and the percentage of land-cover categories within circular regions (buffers) around wells. Several buffer sizes were evaluated; the buffer size that provided the strongest relation was selected for use in the logistic regression models. (3) Relations between concentrations of atrazine/DEA and nitrate in ground water and atrazine use, fertilizer use, geology, hydrogeomorphic regions, land cover, precipitation, soils, and well-construction data were evaluated, and several preliminary multivariate models with various combinations of independent variables were constructed. (4) The multivariate models that best predicted the presence of atrazine/DEA and elevated concentrations of nitrate in ground water were selected. (5) The accuracy of the multivariate models was confirmed by validating the models with an independent set of ground-water quality data. (6) The multivariate models were entered into a geographic information system and the probability GRIDS were constructed.

Description

We propose novel and real-time smart software tools to process spectroscopy data. Material abundance or compositional maps will be generated for rover guidance, sample selection, and other scientific missions. First, we propose a novel anomaly detector called clustered kernel Reed-Xiaoli (CKRX) algorithm. This tool was developed by us, is fast, and can achieve very high anomaly detection rate in hyperspectral images from the Air Force. This is important in planetary missions because we may need to look for some anomalous regions in a scene. Second, if target material signatures are available, then we propose a fast matched signature identification algorithm called Adaptive Subspace Detector (ASD). We compared ASD with several other tools and found that ASD outperformed other methods. Third, if target material signatures are not available, then we propose a new technique called minimum volume constrained non-negative matrix factorization (MVCNMF) to perform unsupervised material identification. In a recent comparative study by using hyperspectral images from the Air Force, the MVCNMF performed better than some conventional unsupervised methods. Fourth, the above tools can be implemented in a parallel processing architecture, in which the computations are distributed to multiple cores. We have applied it to speech processing and genomic processing recently. Real-time performance is achievable.
