      Description:

      A Digital Orthophoto Quadrangle (DOQ) is a computer-generated image of an aerial photograph in which the image displacement caused by terrain relief and camera tilt has been removed. The DOQ combines the image characteristics of the original photograph with the georeferenced qualities of a map. DOQs have a 1-meter ground resolution and are available in black and white (B/W) and/or color-infrared (CIR).

      arrow

      This is an aerial collection of 3.75-minute (quarter-quad) DOQs cover an area measuring 3.75-minutes longitude by 3.75-minutes latitude. Quarter-quad DOQs are often available in both Native and GeoTIFF formats. Native format consists of an ASCII keyword header followed by a series of 8-bit binary image lines for B/W and 24-bit band-interleaved-by-pixel (BIP) for color. DOQs in Native format are cast to the Universal Transverse Mercator (UTM) projection and referenced to either the North American Datum (NAD) of 1927 (NAD27) or the NAD of 1983 (NAD83). GeoTIFF format consists of a georeferenced Tagged Image File Format (TIFF), with all geographic referencing information embedded within the .tif file. DOQs in GeoTIFF format are cast to the UTM projection and referenced to NAD83. The average file size of a B/W quarter quad is 40-45 megabytes, and a color file is generally 140-150 megabytes. Quarter-quad DOQs are distributed on CD-ROM, DVD, 8-mm tape, and File Transfer Protocol (FTP) as uncompressed files.

      A downloadable software is available (DOQQ-to-GeoTIFF conversion) which will convert a DOQ image from Native to GeoTIFF format in either NAD27 or NAD83.

      Description:

      This is an aerial collection of high resolution orthoimagery acquired by the U.S. Geological Survey (USGS), along with the National Geospatial-Intelligence Agency (NGA) for the major metropolitan areas, and state capitals of the United States. The orthoimagery are natural color, black and white, or color infrared. The resolution of the orthoimagery is 0.3 meters to 0.75 meters, depending on the source imagery.

      arrow

      As an essential element of The National Map, http://nationalmap.gov, the need for up-to-date imagery is critical for Homeland Security and Emergency Response. The Orthoimagery category is one of the framework layers for The National Map. The imagery can be used as a base layer for updating or deriving additional geographic information, such as transportation networks, hydrographic features, elevation, and land cover.

      The imagery is available as Universal Transverse Mercator (UTM) projection and referenced to North American Datum of 1983, unless otherwise specified in the metadata. For example, the New Jersey orthoimagery is available as New Jersey State Plane NAD83. The file format is Georeferenced Tagged Image File Format (GeoTIFF).

          National Agriculture Imagery Program (NAIP)arrow

      Description

      This is an aerial collection of National Agriculture Imagery Program (NAIP) images that have a one meter ground sample distance (GSD) with a horizontal accuracy that matches within three meters of a reference ortho image, and a two meter GSD image that matches within 10 meters of reference ortho imagery.

      arrow

      The National Agriculture Imagery Program (NAIP) acquires imagery during the agricultural growing seasons in the continental U.S. A primary goal of the NAIP program is to enable availability of digital ortho photography within a year of acquisition.

      NAIP imagery can be acquired under two sets of specifications: A one meter ground sample distance (GSD) with a horizontal accuracy that matches within three meters of a reference ortho image, and a two meter GSD image that matches within 10 meters of reference ortho imagery. The reference ortho imagery is mosaicked digital ortho quarter quads (DOQs) that were used to digitize USDA FSA common land unit boundaries.

      NAIP imagery products are available either as quarter quad tiles or as compressed county mosaics (CCM). The mosaics are generated by compressing digital quarter quadrangle image tiles scanned from natural color positive or color infrared positive aerial film into a single mosaic. The mosaic may cover all or portions of an individual final product. Each individual image tile within the mosaic covers a 3.75 x 3.75 minute quarter quadrangle plus a 360 meter buffer on all four sides. All individual tile images and the resulting mosaic were rectified to the UTM coordinate system, NAD 83 and cast into a single predetermined UTM zone. Contractually, every attempt will be made to comply with the 10% cloud cover per quarter quad tile, weather conditions permitting.

      The one meter GSD NAIP imagery is intended to provide updated digital ortho photography. The two meter GSD NAIP imagery is intended to support USDA programs that require current imagery acquired during the agricultural growing season but do not require high horizontal accuracy.

      Description:

      This aerial dataset is a collection of GeoTIFF format natural color images that cover regions of Alabama, Louisiana, and Mississippi that were affected by Hurricane Katrina in August 2005.

      arrow

      The raw imagery used to generate the final image tiles was collected simultaneously with airborne GPS and IMU data, which was used to georeference the raw imagery. The raw imagery was rectified to a plane of constant elevation and mosaiced to generate the final image tiles. Each image tile provides data for a nominal 1.875 minute (in latitude and longitude) cell area. The source imagery was obtained in September 2005 and used to produce georeferenced, planar rectified imagery with a one foot ground resolution. Imagery was acquired at one foot ground sample distance (GSD) resolution. Flight height maintained during mission was 10,000 feet AGL. The imagery was captured at 12-bit radiometric resolution and converted to 8-bit radiometric resolution during post processing. The imagery was obtained and processed by all digital means beginning with data acquisition using an ADS40 digital airborne sensor. The orthophotos are available in GeoTIFF form in Geographic Coordinates (decimal degrees), NAD83.

      Description:

      This is a collection of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) imagery. ASTER provides fourteen spectral bands with 15- to 90-meter resolution depending on bands.

      arrow

      ASTER is a cooperative effort between NASA,  Japan's Ministry of Economy, Trade and Industry (METI) and Japan's Earth Remote Sensing Data Analysis Center (ERSDAC).

      ASTER is one of a number of instruments on board the Terra platform, which was launched in December 1999. ASTER does not acquire data continuously, and its sensors are activated only to collect specific scenes upon request.

      The instrument consists of three separate telescopes, each of which provides different spectral range and resolution. The VNIR (visible and near-infrared) sensor provides 4 bands at 15-meter resolution. The SWIR (short-wave infrared) sensor provides 6 bands at 30-meter resolution. The TIR (thermal infrared) sensor provides 5 bands at 90-meter resolution. The swath width for all sensors is 60 kilometers.

      ASTER data distributed from the Land Processess Distributed Active Archive Center is available in the Universal Transverse Mercator (UTM) projection, with a resampling method of cubic convolution for daytime scenes and nearest neighbor for nighttime scenes. Files are in the HDF-EOS format.

          Disaster Monitoring Constellation (DMC) arrow

      Description:

      The DMC collection is currently imagery from Nigeriasat-1 collected on September 2nd, 2005. The image covers an area of 400 x 220 km, showing the Mississippi Delta, New Orleans area and much of the gulf coast.

      arrow

      The Disaster Monitoring Constellation (DMC) was designed as a proof of concept constellation, capable of multispectral imaging of any part of the world every day. It is unique in that each satellite is independently owned and controlled by a separate nation, but all satellites have been equally spaced around a sun-synchronous orbit to provide daily imaging capability.

      The satellites are all designed and built at Surrey Satellite Technology Ltd. (SSTL) in the UK. Through the support of the British National Space Centre, SSTL owns and operates the UK satellite in the constellation.

      Although its headline objective is to support the logistics of disaster relief, its main function is to provide independent daily imaging capability to the partner nations; Algeria, Nigeria, Turkey, UK and China. The first 4 satellites are now in orbit and the 5th is in construction for China at the Surrey Space Centre.

      The DMC satellites provide a unique Earth Observation resource that enables daily revisit anywhere in the world. This is possible with only a few satellites because they are designed to image a large area of up to 600 x 600km. This greatly improves the value of the data as it often avoids the need for mosaics of images from different seasons.

          Earth Observing-1 Hyperion/ALI arrow

      Description:

      This collection of imagery includes 10-30 meter multispectal (Advanced Land Imager (ALI)). and hyperspectral (Hyperion) data from the Earth Observing-1 satellite.

      arrow

      The Earth Observing-1 (EO-1) satellite was launched November 21, 2000 as a one-year technology demonstration/validation mission. After the initial technology mission was completed, NASA and the USGS agreed to the continuation of the EO-1 program as an Extended Mission. The EO-1 Extended Mission is chartered to collect and distribute Hyperion hyperspectral and Advanced Land Imager (ALI) multispectral products according to customer tasking requests.

      The EO-1 satellite follows the WRS-2 path and row system with a 16-day repeat cycle. The spacecraft follows Landsat 7 by approximately one minute, and is also capable of cross-track pointing to allow potential imaging within one adjacent WRS path in each direction from nadir.

      Instruments on board the EO-1 spacecraft:

      • Advanced Land Imager (ALI) provides image data from ten spectral bands (band designations). The instrument operates in a pushbroom fashion, with a spatial resolution of 30 meters for the multispectral bands and 10 meters for the panchromatic band. The standard scene width is 37 kilometers. Standard scene length is 42 kilometers, with an optional increased scene length of 185 kilometers (additional information).
      • Hyperion collects 220 unique spectral channels ranging from 0.357 to 2.576 micrometers with a 10-nm bandwidth. The instrument operates in a pushbroom fashion, with a spatial resolution of 30 meters for all bands. The standard scene width is 7.7 kilometers. Standard scene length is 42 kilometers, with an optional increased scene length of 185 kilometers (additional information).

      Description:

      This is a collection of Landsat TM Orthorectified Mosaics data derived from a global set of high-quality, relatively cloud-free orthorectified TM imagery from Landsats 4-5. The average acquisition date for the Landsat Orthorectified TM data is 1990 (+/- 3 years). However, individual scenes may range from 1985 to 1996.

      arrow

      This dataset was selected and generated through NASA's Commercial Remote Sensing Program, as part of a cooperative effort between NASA and the commercial remote sensing community to provide users with access to quality-screened, high-resolution satellite images with global coverage over the Earth's land masses. The data collection was compiled via NASA contract with Earth Satellite Corporation (Rockville, MD) in association with NASA's Scientific Data Purchase program.

      The Landsat Orthorectified TM Mosaics data collection is derived from approximately 7,461 TM (Landsat 4-5) images, which were selected to provide a full set of global coverage (circa 1990). All selected images were either cloud-free or contained minimal cloud cover. In addition, only images with a high quality ranking in regards to the possible presence of errors such as missing scans or saturated bands were selected.

      These Landsat data have been orthorectified, using geodetic and elevation control data to correct for positional accuracy and relief displacement. Large blocks of Landsat data were adjusted through a patented procedure using pixel correlation to acquire tie-points within the overlap area between adjacent Landsat images. The Landsat TM scenes were mosaicked by matching individual histograms and feathering overlapping areas together to create a TM Mosaic product. The mosaics are contrast enhanced color image data products comprised of Landsat TM bands 7, 4, 2 composited in red, green, and blue, respectively. The resulting mosaics are made up of several Landsat scenes covering a 5-degree (north-south) segment of a standard, 6-degrees (east-west), UTM partition.

      All Landsat Orthorectified data products have been pre-processed according to a standardized set of processing parameters. The processing parameters, format, and media options will vary slightly according to product type:
      Level of processingTerrain corrected
      Number of bands (Band designations) 3 (bands 7,4,2)

      Description:

      This is a collection of LIDAR data for various counties along the gulf coast.

      arrow

      A relatively new technology, called Light Detection and Ranging or LIDAR, is being used as a tool to measure heights of buildings, trees, and even the ground underneath trees at very high accuracy and resolution. LIDAR is a remote sensing system mounted in the bottom of an airplane or helicopter. This system shoots out laser beams at very high speeds- up to 100,000 times per second. These laser beams bounce off of the trees, buildings and ground below, and return to the aircraft where they are converted to elevation measurements. These measurements allow scientists and managers across the country to use LIDAR for a variety of applications, such as flood modeling, vegetation mapping, and homeland security.

      LIDAR in its raw form is a “cloud” of points recorded from where the laser beam bounced off of an object (such as a tree or building) These points can provide a wealth of information about forests, buildings, and even record the ground beneath the trees. By converting these points into three-dimensional models, we can combine them with imagery, such as the examples above, to create virtual cities and virtual forests that allow people to explore and model areas in three dimensions.

      Description

      This is a collection of 1 arc second (30 meter spacing) and 1/3 arc second (10 meter spacing) digital raster elevation data that covers the conterminous U.S., Alaska, Hawaii, Puerto Rico, and Virgin Islands.

      arrow

      The USGS National Elevation Dataset (NED) has been developed by merging the highest-resolution, best quality elevation data available across the United States into a seamless raster format. NED is the result of the maturation of the USGS effort to provide 1:24,000-scale Digital Elevation Model (DEM) data for the conterminous US and 1:63,360-scale DEM data for Alaska. The dataset provides seamless coverage of the United States, HI, AK, and the island territories. NED has a consistent projection (Geographic), resolution (1 arc second), and elevation units (meters). The horizontal datum is NAD83, except for AK, which is NAD27. The vertical datum is NAVD88, except for AK, which is NAVD29. NED is a living dataset that is updated bimonthly to incorporate the "best available" DEM data. As more 1/3 arc second (10m) data covers the US, then this will also be a seamless dataset.

      Description:

      This is a collection of 1 arc second (30 meter spacing) and 3 arc second (90 meter spacing) elevation data that covers over 80 percent of the Earth's land surface, everything between 60 degrees North and 56 degrees South latitude.

      arrow

      The Shuttle Radar Topography Mission (SRTM) is a partnership between NASA and the National Geospatial-Intelligence Agency (NGA). Flown aboard the NASA Space Shuttle Endeavour (11-22 February 2000), SRTM fulfilled its mission to map the world in three dimensions. The USGS is under agreement with NGA and NASAs Jet Propulsion Laboratory to distribute the data. SRTM utilized dual Spaceborne Imaging Radar (SIR-C) and dual X-band Synthetic Aperture Radar (X-SAR) configured as a baseline interferometer. SRTM data is being used to generate a digital topographic map of the Earth's land surface with data points spaced every 1 arc second for the United States of latitude and longitude (approximately 30 meters). The SRTM "finished" data meet the absolute horizontal and vertical accuracies of 20 meters (circular error at 90% confidence) and 16 meters (linear error at 90% confidence), respectively, as specified for the mission.
