WorldView-2: High-Resolution Multispectral Satellite Imagery

WorldView-2 Level 1B imagery is a collection of high-resolution satellite data covering the global land surface. The sensor-corrected product includes eight spectral bands in the visible and near-infrared range, with a spatial resolution of 1.85 meters at nadir and a temporal resolution of approximately 1.1 days. Data is available from October 2009 to the present in NITF and GeoTIFF formats.

Use Cases

• Land cover classification based on eight distinct spectral bands including coastal, red edge, and near-infrared wavelengths.
• Change detection and time-series analysis leveraging a temporal resolution of approximately 1.1 days and coverage from 2009 onward.
• Environmental monitoring and precision agriculture using high-resolution (1.85m) multispectral data.
• Sensor-corrected radiometric analysis for applications requiring un-projected, raw imagery data.

Strengths

• Provides high spatial resolution of 1.85 meters at nadir for detailed surface observation.
• Offers eight spectral bands, including coastal and red edge, which are useful for specialized analyses.
• Has a long temporal coverage from October 2009 to the present, supporting longitudinal studies.
• Features a high revisit rate with a temporal resolution of approximately 1.1 days.

Limitations

• Access is restricted by a National Geospatial-Intelligence Agency (NGA) license and requires program approval, limiting availability.
• Metadata completeness is low; column names, row counts, and specific file sizes are not provided across platforms.
• There is a minor conflict in the description of the data provider (Maxar Technologies vs. Vantor, Inc.).
