Infrared and visible imagery was registered by the MSU-E instrument aboard the PRIRODA module of the MIR space station, launched and docked in April 1996. The dataset contains data from three spectral channels (0.5-0.6, 0.6-0.7, and 0.8-0.9 micrometers) with a spatial resolution of 14x36 meters and a 28 km field of view. The PRIRODA project was an international scientific program involving data centers from multiple countries, coordinated by SCIOPS.
Use Cases
- Land cover classification based on multispectral reflectance data in visible and near-infrared bands.
- Environmental change detection over time using high-resolution (14x36m) imagery.
- Calibration and validation of newer satellite sensors using historical data from a known instrument.
- Analysis of surface features within the instrument's 28-kilometer field of view.
Strengths
- Data originates from a specific, documented scientific instrument (MSU-E) with known spectral bands.
- Spatial resolution (14x36 meters) and field of view (28 km) are explicitly stated, allowing for scale assessment.
- Imagery covers both infrared and visible spectra, providing multiple data layers for analysis.
Limitations
- Row count, file formats, and sample data are unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics and data structure must be inferred after download.
- Last update date is unknown; data freshness and potential gaps in temporal coverage are unverified.
Provenance
- Source
- SCIOPS, via NASA Earthdata (nasa_earthdata).
- Collection Method
- Collected by the MSU-E instrument onboard the PRIRODA module of the MIR space station.
- Time Range
- Data collection began after the module's launch and docking in April 1996; specific end date is unknown.
- Freshness
- null
- Geography
- Likely global coverage from the MIR space station's orbit; specific regions are not stated.
