What is the spatial resolution of the panchromatic sensor on the GeoEye-1 satellite?

The spatial resolution of the panchromatic sensor on the GeoEye-1 satellite is 0.41 meters. This means that the satellite can capture images with a level of detail where one pixel in the image corresponds to a 0.41-meter square on the ground. This high level of resolution is significant for applications that require detailed imagery, such as urban planning, infrastructure monitoring, and environmental assessments. The panchromatic capability allows for higher detail in grayscale images, which can enhance features in the landscape compared to lower-resolution multispectral imagery. Understanding spatial resolution is crucial in remote sensing, as it determines the level of detail that can be analyzed in the captured images.
