JERS-1 Satellite SAR Geocoded Imagery

Synthetic Aperture Radar data from the JERS-1 satellite launched by Japan's National Space Development Agency on February 11, 1992. The dataset consists of Standard Geocoded Images with a spatial resolution of 12.5 meters, processed with radiometric and geometric corrections. Data production concluded in October 1998.

Use Cases

• Analyze land deformation or geological features using the 12.5m resolution L-band SAR backscatter data.
• Study historical land cover from 1992-1998 by processing the Standard Geocoded Images in UTM or PS map projection.
• Perform multi-temporal analysis by comparing JERS-1/SAR L2.1 data with newer SAR missions, leveraging its radiometrically corrected imagery.

Strengths

• Data is geocoded with radiometric and geometric corrections applied.
• Provides a consistent historical record from a dedicated L-band SAR mission operational for over 6 years.

Limitations

• Temporally stale, with the last update in 1998 and no new acquisitions.
• Limited metadata available regarding specific geographic coverage and scene count.
