Kanopus-V Satellite Multispectral Imagery For Surface Monitoring

Multispectral images from the Kanopus-V satellite's Multiband Surveying Sensor capture Earth's surface in four spectral bands: blue (460-520 nm), green (510-600 nm), red (630-690 nm), and near-infrared (750-840 nm). The sensor provides a nadir spatial resolution of 12 meters and a swath width of 20 km, with a revisit frequency ranging from 3 to 16 days depending on latitude. Data is provided by the CEOS_EXTRA organization for monitoring anthropogenic and natural emergencies.

Use Cases

• Classify land cover types using the four spectral bands (blue, green, red, near-infrared) for agricultural and forestry inventory.
• Monitor vegetation health and stress by calculating indices like NDVI from the red and near-infrared spectral bands.
• Detect and assess the extent of natural disasters such as floods or fires by analyzing changes in surface reflectance across the multispectral bands.
• Support cartographic applications by utilizing the 12-meter nadir resolution imagery for mapping and construction planning.
• Track changes in natural resources over time by leveraging the sensor's 3 to 16-day revisit capability for temporal analysis.

Strengths

• Provides data in four distinct spectral bands (blue, green, red, near-infrared) enabling detailed spectral analysis.
• Offers a nadir spatial resolution of 12 meters suitable for regional-scale monitoring.
• Sensor can be pointed up to 40 degrees from nadir, enabling a wide swath view of up to 920 km.

Limitations

• The revisit frequency is variable, ranging from 3 to 16 days, which may be insufficient for monitoring rapidly evolving events.
• Specific data volume, temporal coverage, and geographic extent are not provided, limiting initial assessment of scope.
• The 12-meter spatial resolution is too coarse for applications requiring fine detail, such as identifying individual small structures.
