  • ABoVE: Ecosystem Map, Great Slave Lake Area, Northwest Territories, Canada, 1997-2011

    https://cmr.earthdata.nasa.gov/search/concepts/C1657940496-ORNL_DAAC.xml
    Description:

    This dataset provides an ecosystem type map at 12.5 meter pixel spacing and 0.2 ha minimum mapping unit for the area surrounding Great Slave Lake, Northwest Territories, Canada for the time period 1997 to 2011. The map includes nine classes for peatland, wetland, and upland areas derived from a Random Forest classification trained on multi-date, multi-sensor remote sensing images across the study extent, and using field data and high-resolution Worldview-2 image interpretation for training and validation. The nine classes are: Water, Marsh, Swamp, Open Fen, Treed Fen, Bog, Upland Deciduous, Upland Conifer, and Sparsely Vegetated. A tenth map class identifies areas of historical fires (prior to 2011) that are currently undergoing post-fire successional revegetation. This dataset provides an ecosystem type map of the area before the large fire season of 2014 to better understand the effects of fires in the area.

  • ALOS AVNIR-2 Data

    https://cmr.earthdata.nasa.gov/search/concepts/C1214560353-JAXA.xml
    Description:

    The Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) is a visible and near infrared radiometer for observing land and coastal zones. It provides better spatial land-coverage maps and land-use classification maps for monitoring regional environments. AVNIR-2 is a successor to AVNIR that was on board the Advanced Earth Observing Satellite (ADEOS), which was launched in August 1996. Its instantaneous field-of-view (IFOV) is the main improvement over AVNIR. AVNIR-2 also provides 10m spatial resolution images, an improvement over the 16m resolution of AVNIR in the multi-spectral region. Improved CCD detectors (AVNIR has 5,000 pixels per CCD; AVNIR-2 7,000 pixels per CCD) and electronics enable this higher resolution. A cross-track pointing function for prompt observation of disaster areas is another improvement. The pointing angle of AVNIR-2 is +44 and - 44 degree. --------------------------------- AVNIR-2 Characteristics --------------------------------- Number of Bands 4 Wavelength Band 1 : 0.42 to 0.50 micrometers Band 2 : 0.52 to 0.60 micrometers Band 3 : 0.61 to 0.69 micrometers Band 4 : 0.76 to 0.89 micrometers Spatial Resolution 10m (at Nadir) Swath Width 70km (at Nadir) S/N >200 MTF Band 1 through 3 : >0.25 Band 4 : >0.20 Number of Detectors 7000/band Pointing Angle - 44 to + 44 degree Bit Length 8 bits

    https://cmr.earthdata.nasa.gov/search/concepts/C1214560381-JAXA.xml
    Description:

    ALOS is a comprehensive earth observing satellite system which includes optical sensors for high resolution observation, wide area observation, and fine accuracy DEM production, and SAR with adjustable off-nadir observation function. Objectives of the ALOS system development and operation are (1) Development and update of maps for Japan and other countries - including those in the Asia-Pacific region (Cartography), (2) Regional observation for sustainable development (Regional Observation), (3) Timely disaster monitoring around the world (Disaster Monitoring), and (4) Survey of natural resources (Resource Survey). ALOS has three sensors for Earth observations, Panchromatic Remote-Sensing Instrument for Stereo Mapping (PRISM), Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2), and Phased Array type L-band Synthetic Aperture Radar (PALSAR). ----------------------------------------------- ALOS ----------------------------------------------- Launch Vehicle H-IIA Launch Date January 24, 2006 Launch Site Tanegashima Space Center, Kagoshima Weight Approx. 4,000 kg Designed Life Span 3-5 years Orbit Sun-Synchronous Subrecurrent Local Time at Desending Node 10:30 AM ? 15min.

  • ALOS PALSAR Data

    https://cmr.earthdata.nasa.gov/search/concepts/C1214560405-JAXA.xml
    Description:

    The Phased Array type L-band Synthetic Aperture Radar (PALSAR) is an active microwave sensor using L-band frequency to achieve cloud-free and day-and-night land observation. It provides higher performance than theJERS-1's synthetic aperture radar (SAR). Fine resolution in a conventional mode, but PALSAR will have another advantageous observation mode. ScanSAR, which will enable us to acquire a 250 to 350km width of SAR images (depending on the number of scans) at the expense of spatial resolution. This swath is three to five times wider than conventional SAR images. The development of the PALSAR is a joint project between JAXA and the Japan Resources Observation System Organization (JAROS).

  • ALOS PRISM Data

    https://cmr.earthdata.nasa.gov/search/concepts/C1214560379-JAXA.xml
    Description:

    The Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) is a panchromatic radiometer with 2.5m spatial resolution at nadir. Its extracted data will provide a highly accurate digital surface model (DSM). PRISM has three independent optical systems for viewing nadir, forward and backward producing a stereoscopic image along the satellite's track. Each telescope consists of three mirrors and several CCD detectors for push-broom scanning. The nadir-viewing telescope covers a width of 70km; forward and backward telescopes cover 35km each. The telescopes are installed on the sides of the optical bench with precise temperature control. Forward and backward telescopes are inclined +24 and -24 degrees from nadir to realize a base-to-height ratio of 1.0. PRISM's wide field of view (FOV) provides three fully overlapped stereo (triplet) images of a 35km width without mechanical scanning or yaw steering of the satellite. Without this wide FOV, forward, nadir, and backward images would not overlap each other due to the Earth's rotation.--------------------------------PRISM Characteristics --------------------------------Number of Bands 1 (Panchromatic) Wavelength 0.52 to 0.77 micrometers Number of Optics 3 (Nadir; Forward; Backward) Base-to-Height ratio 1.0 (between Forward and Backward view) Spatial Resolution 2.5m (at Nadir) Swath Width 70km (Nadir only) / 35km (Triplet mode) S/N >70 MTF >0.2 Number of Detectors 28000 / band (Swath Width 70km)14000 / band (Swath Width 35km) Pointing Angle -1.5 to +1.5 degrees(Triplet Mode, Cross-track direction) Bit Length 8 bits Observation Modes: Mode 1 Triplet observation mode using Forward, Nadir, and Backwardviews (Swath width is 35km)Mode 2 Nadir (70km) + Backward (35km) Mode 3 Nadir (70km) Mode 4 Nadir (35km) + Forward (35km) Mode 5 Nadir (35km) + Backward (35km) Mode 6 Forward (35km) + Backward (35km) Mode 7 Nadir (35km) Mode 8 Forward (35km) Mode 9 Backward (35km)
