Global optical satellite imagery from the CBERS-2 satellite's Wide Field Imager (WFI). The data has a spatial resolution of 260 meters and a ground swath of 890 kilometers, enabling complete Earth surface coverage approximately every 5 days. The dataset is provided by the CEOS_EXTRA organization and was last updated in 2009.
Use Cases
- Monitor large-scale land cover changes based on the 890 km swath and 5-day revisit cycle.
- Analyze regional environmental patterns based on the 260-meter spatial resolution optical observations.
- Conduct time-series analysis of ecosystem dynamics based on the global coverage and frequent revisit capability.
Strengths
- Provides a synoptic view with a wide 890-kilometer ground swath.
- Offers global coverage with a revisit time of approximately 5 days.
- Spatial resolution of 260 meters is specified.
Limitations
- Last updated 2009-01-01 23:59:59.999000; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file formats are unknown, which may limit suitability assessment.
