Landsat Thematic Mapper Imagery for Japan Region

LANDSAT Thematic Mapper data provides 7-channel multispectral imagery covering visual, near-infrared, and thermal infrared spectra. The Earth Observation Center of NASDA collects and corrects this data, covering a circular area approximately 5000 km in diameter. Data is received on weekdays and every other Saturday, with products distributed as magnetic tape and imagery.

Use Cases

• Classify land cover types using the 7 spectral bands, including near-infrared and thermal infrared channels.
• Monitor environmental changes over time by analyzing time-series imagery received on a near-daily schedule.
• Perform radiometric and geometric analysis on pre-corrected data from the Earth Observation Center.
• Conduct regional studies within the 5000 km diameter coverage area centered on the NASDA station.

Strengths

• Covers a large circular area of approximately 5000 km in diameter.
• Provides data in 7 distinct electromagnetic spectral channels.
• Data undergoes both radiometric and geometric correction before distribution.

Limitations

• Specific sample size, row count, and temporal range are not provided.
• Data format and accessibility details (e.g., magnetic tape) may require specialized handling.
• Geographic coverage is limited to the reception area of the NASDA station in Japan.
