    The JERS-1 Optical System (OPS) is composed of a Very Near Infrared Radiometer (VNIR) and a Short Wave Infrared Radiometer (SWIR). The instrument has 8 observable spectral bands from visible to short wave infrared.

    The JERS-1 OPS products are available in GeoTIFF format. These products are available only for the VNIR sensor. All four bands are corrected. The correction consists in a vertical and horizontal destriping, the radiometry values are expanded from the range [0,63] to the range [0,255]. No geometrical correction is applied on level 1. The pixel size of approximately 18 x 24.2 metres for raw data is newly dimensioned to 18 x 18 metres for System Corrected data using a cubic convolution algorithm.

    Disclaimer:

    • Cloud coverage for JERS OPS products has not been computed using an algorithm. The cloud cover assignment was performed manually by operators at the acquisition stations.
    • Due to missing attitude information, the Nadir looking band (band 3) and the corresponding forward looking band (band 4) are not well coregistered, resulting in some accuracy limitations.
    • The quality control was not performed systematically for each frame. A subset of the entire JERS Optical dataset was selected and manually checked. As a result of this, users may occasionally encounter issues with some of the individual products.

    Last update: 25 September 2018

    The JSA_SLC_1P product is comparable to the ESA SLC/IMS images generated for Envisat ASAR and ERS SAR instruments. It is a slant-range projected complex image in zero-Doppler SAR coordinates.

    The data is sampled in natural units of time in range and along track, with the range pixel spacing corresponding to the reciprocal of the platform ADC rate and the along track spacing to the reciprocal of the PRF.

    Data is processed to an unweighted Doppler bandwidth of 1000Hz, without sidelobe reduction. The product is suitable for interferometric, calibration and quality analysis applications.

    The JSA_PRI_1P product is comparable to the ESA PRI/IMP images generated for Envisat ASAR and ERS SAR instruments. It is a ground range projected detected image in zero-Doppler SAR coordinates, with a 12.5 metre pixel spacing. It has four overlapping looks in Doppler covering a total bandwidth of 1000Hz, with each look covering a 300Hz bandwidth. Sidelobe reduction is applied to achieve a nominal PSLR of less than -21dB. The image is not geocoded, and terrain distortion (foreshortening and layover) has not been removed.

    TRAINING ON EARTH OBSERVATION
    Bratislava, Slovakia
    17 - 21 September 2018

    The European Space Agency (ESA) in cooperation with the Ministry of Education, Science, Research and Sport of the Slovak Republic organised a Training Course on Earth Observation, that took place from 17 – 21 September 2018 in the premises of the Slovak Centre of Scientific and Technical Information (SCSTI) in Bratislava.

    The main aim of this course was to promote and disseminate Earth Observation (EO) technologies in various scientific and industrial fields, covering optical and radar sensors, with emphasis on combining Sentinel-1 and Sentinel-2 for environmental applications.

    The participants included researchers, students, PhD students and young professionals that use EO technology within their daily work and wanted to improve their knowledge. The majority of them were from ESA European Cooperating States (especially from Slovakia), though candidates from other countries were selected to broaden the geographic and cultural range of participants and stimulate networking.

    MAIN TOPICS

    • Basics of radar (SAR) and optical Remote Sensing
    • Remote Sensing applications:
      • Detection of land cover and land cover changes
      • Forest monitoring
      • Agricultural crops monitoring
      • Monitoring snow cover
      • Support to Natural Hazards management - Floods and Forest Fires.
      • Integration of SAR/Optical Remote Sensing for Land, Ice and Snow Applications.
