Description
Vescent Photonics propose to develop a chip-sized narrow linewidth (< 50 kHz), widely tunable (> 10 nm's) diode laser that will be suitable for a wide variety of NASA remote sensing missions. The proposed laser platform enables easy selection of the laser center wavelength; these lasers can be easily built for any wavelength that a diode laser gain chip exists (< 670 nm to > 2.5 microns). Since spectral features of important molecular species cover a large wavelength window this center-wavelength flexibility is advantageous. This effort will focus on lasers operating in the 1.57 and 2.0 micron CO2 band, and the 1.26 micron O2 band, such as is required for ASCENDS-type missions. Rapid wide wavelength tunability will enable scans over large portions of spectral bands, which can minimize the impact of contaminant and thermal effects on total column density measurement. These lasers will provide for very fast phase (up to 10 GHz) modulation and be built with space qualifiable components. Collaborative relationships with established aerospace companies will be exploited to facilitate insertion of this technology into NASA missions.

Summary
Description
The Office of the National Geodetic Survey has produced a series of high-resolution gravimetric geoid models, hybrid geoid models, and associated deflection of the vertical products for the United States. The gravimetric geoid models are referred to the Geodetic Reference System of 1980 (GRS80), centered at the most recent ITRF reference frame of origin. The hybrid geoid models and associated deflection of the vertical models refer to the NAD 83 datum, and are used as a transformation between NAD 83 and NAVD 88.Major geoid products were released in 1990, 1993, 1996, 1999, and 2003. A new model is planned for 2006. Each release represents an improvement in accuracy over the previous models. The newest (2003) products are (1) USGG2003, a gravimetric geoid model, (2) GEOID03, a hybrid geoid model. USGG2003 converts between ITRF00 and an enhanced EGM96 geoid for all regions (CONUS, Alaska, Hawaii, and Puerto Rico/Virgin Islands). GEOID03 converts between NAD 83 and NAVD 88 for CONUS only, and between NAD 83 and the enhanced EGM96 geoid for all other regions.Within the conterminous US, most users should use GEOID03. It is constructed specifically to relate GPS ellipsoid heights in the NAD 83 datum and orthometric heights in the NAVD 88 datum. These are the datums used in many maps and charts, and most applications require that consistency. A new model, GEOID06, will be generated this year only for Alaska to provide a transformation between NAD 83 and NAVD 88 - where it is available. NAVD 88 coverage in Alaska is not complete and may not be suitable for all regions. No NAVD 88 coverage exists in Hawaii or PR/VI, hence only the EGM96 geoid surface is currently valid there.The GEOID03 product comprises eight files for the conterminous US, four files for Alaska, and one each for Hawaii and Puerto Rico/Virgin Islands. Each file contains geoid heights on a one minute by one minute grid in little-endian binary (PC compatible). The INTG program is supplied at the download site to interpolate to a specific position within these grids. Another program, XNTG, is supplied to extract subsets and convert the grids. Both are in FORTRAN, are available compiled and as source code, and can byte-swap the grids if needed on a Unix platform. There is also an on-line geoid computational facility within the NGS Geodetic Tool Kit at http://www.ngs.noaa.gov/TOOLS. Similar files, programs, and on-line computational facilities exist for USGG2003 and DEFLEC99. See the GEOID section of the NGS Web site at http://www.ngs.noaa.gov/GEOID.Geoid and deflection of the vertical models for Mexico and the Caribbean were computed in 1997 and are distributed as MEXICO97, DMEX97, CARIB97, and DCAR97 respectively. NGS also offers technical information concerning the construction of the geoid models and practical information concerning its use on the NGS web site at http://www.ngs.noaa.gov/GEOID. NGS also offers a workshop concerning GPS derived heights and the use of the geoid models to convert from GPS derived heights to orthometric heights (see http://www.ngs.noaa.gov/PC_PROD/WorkShops/).

TASK NAME: USGS New York CMGP Sandy Lidar 0.7 Meter NPS LIDAR lidar Data Acquisition and Processing Production Task USGS Contract No. G10PC00057 Task Order No. G14PD00797 Woolpert Order No. 073666 CONTRACTOR: Woolpert, Inc. This data set is comprised of lidar point cloud data, raster DEM, hydrologic 3-d breaklines, raster intensity, survey control, project tile index, and project data extent. This task order requires lidar data to be acquired over several areas in New York State to include the entire counties of Bronx, Kings, New York, Richmond, and Queens. Governors, Hoffman, and Swinburne Islands are part of the New York area of interest (AOI), and will be acquired as part of this task order. The total area of the New York Sandy Lidar AOI is approximately 304 square miles. Woolpert acquired lidar data of New York City as part of a task order for the NGA. The flight plan for the New York City NGA Lidar task order was developed with 11 additional cross flights over the Manhattan Metropolitan area to minimize data shadowing and data voids in the lidar dataset caused by tall buildings. The lidar data for the NGA task order was acquired between August 5, 2013 and August 15, 2013. USGS requested use of this data from the NGA, in order to reduce the duplication of lidar data acquisition effort on the New York CMGP Sandy Lidar task order. The NGA approved the use of this lidar data for the USGS task order.Following the approval by NGA, Woolpert was able to utilize the cross flights acquired as part of the NGA task order to minimize data shadowing and data voids caused by tall buildings in the USGS New York CMGP Sandy Lidar task order AOI. The cross flights used in the New York CMGP Sandy 0.7M NPS Lidar Processing task order from the NGA New York City task order were flown on August 6, 2013. The lidar data acquisition parameters for this mission are detailed in the lidar processing report for this task order. The lidar data will be acquired and processed under the requirements identified in this task order. lidar data is a remotely sensed high resolution elevation data collected by an airborne platform. The lidar sensor uses a combination of laser range finding, GPS positioning, and inertial measurement technologies. The lidar systems collect data point clouds that are used to produce highly detailed Digital Elevation Models (DEMs) of the earth's terrain, man-made structures, and vegetation. The task required the LiDAR data to be collected at a nominal pulse spacing (NPS) of 0.7 meters. The final products include classified LAS, one (1) meter pixel raster DEMs of the bare-earth surface in ERDAS IMG Format, and 8-bit intensity images. Each LAS file contains lidar point information, which has been calibrated, controlled, and classified. Additional deliverables include hydrologic breakline data, control data, tile index, lidar processing and survey reports in PDF format, FGDC metadata files for each data deliverable in .xml format, and LAS swath data. Collected swath files that were that were larger than 2GB were provided in multiple sub-swath files, each less than 2GB. Ground conditions: Water at normal levels; no unusual inundation; no snow; leaf off. The tide window requirements for the lidar data acquisition; Tidally impacted waters within the AOI are expected to be acquired at Predicted MLW +- 2 hours exclusive of neap tide.; The bare earth DEMs along the coast may have a variance in the water heights due to temporal differences during the lidar data acquisition and will be represented in DEM as a seam-like anomaly.; One coastal elevation was applied to entire project area. Due to differing acquisition dates and thus differing tide levels there will be areas in the DEM exhibiting what appears to be "digging" water features. Sometimes as much as approximately 1 meter. This was done to ensure that no coastal hydro feature was "floating" above ground surface. This coastal elevation will also affect connected river features wherein a sudden increase in flow will be observed in the DEM to accommodate the coastal elevation value; During Hydrologic breakline collection, Woolpert excluded obvious above-water piers or pier-like structures from the breakline placement. Some features extend beyond the apparent coastline and are constructed in a manner that can be considered an extension of the ground. These features were treated as ground during classification and subsequent hydrologic delineation. In all cases, professional practice was applied to delineate what appeared to be the coast based on data from multiple sources; Due to the many substructures and the complexity of the urban environment, interpolation and apparent "divots" (caused by tinning) may be evident in the surface of the bare earth DEM. In all cases, professional practice was applied to best represent the topography. NOAA OCM has not received any finalized DEMs for this project and do not expec to, therefore any request for these should be directed to USGS' National Map or a contact at Woolpert directly (as listed below).

Summary
Description
This data set collection contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP program is administered by USDA FSA and has been established to support two main FSA strategic goals centered on agricultural production. These are increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs. Ortho imagery provides an effective, intuitive means of communication about farm program administration between FSA and stakeholders. New technology and innovation is identified by fostering and maintaining a relationship with vendors and government partners, and by keeping pace with the broader geospatial community. As a result of these efforts the NAIP program provides three main products: DOQQ tiles, Compressed County Mosaics (CCM), and Seamline shape files. The Contract specifications for NAIP imagery have changed over time reflecting agency requirements and improving technologies. These changes include image resolution, horizontal accuracy, coverage area, and number of bands. In general, flying seasons are established by FSA and are targeted for peak crop growing conditions. The NAIP acquisition cycle is based on a minimum 3 year update of base ortho imagery. The tiling format of the NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 pixel buffer on all four sides. NAIP quarter quads are formatted to the UTM coordinate system using the North American Datum of 1983. NAIP imagery may contain as much as 10% cloud cover per tile.
