Step 1: Concept
Commercial Earth observation satellites are categorized by their spatial resolution, which dictates the smallest object visible in their imagery.
Step 2: Meaning
The GeoEye-1 satellite is renowned for providing extremely high-resolution panchromatic (black and white) imagery.
Step 3: Analysis
• GeoEye-1 technically captures panchromatic imagery at a resolution of 0.41 meters.
• However, due to historic U.S. Government licensing restrictions, commercial distribution of this imagery was often resampled and standardized to a resolution of 0.5 meters.
• In standard geospatial technology curricula, the GeoEye sensor is heavily associated with the 0.5-meter class of high-resolution satellites.
Step 4: Conclusion
The accepted standard educational answer for GeoEye's commercial spatial resolution among the given choices is 0.5 m.
Final Answer: (A)
