As satellite technology improves, it's important to understand the differences between various satellites and their capabilities. In this comparison, we'll be taking a look at SPOT-6 and SPOT-7 imagery to see how they stack up against each other.
Resolution
Resolution plays a crucial role in satellite imagery, and in this category, SPOT-7 comes out on top. With a 1.5 meter resolution, it's able to capture more detail than SPOT-6, which has a resolution of 1.5 to 6 meters.
Spectral Resolution
When it comes to spectral resolution, SPOT-6 is the clear winner. With a variety of spectral bands ranging from blue to near-infrared, it's able to capture a wider range of data for analysis. SPOT-7, on the other hand, only has four spectral bands.
Swath Width
The swath width of a satellite image is the area that can be imaged in a single pass. In this category, both SPOT-6 and SPOT-7 are on par with each other, with a swath width of 60 kilometers.
Sensor Modes
SPOT-7 has a unique sensor mode known as "Panchromatic+" which combines the panchromatic band with the blue, green, and red bands to provide higher resolution imagery with better color fidelity. SPOT-6 doesn't have this feature, which makes SPOT-7 the superior option in this category.
Conclusion
Overall, SPOT-7 has a few advantages over SPOT-6 with its higher resolution and unique sensor modes. However, SPOT-6 also has its own set of advantages with its wider spectral resolution. Ultimately, the choice between the two depends on the specific needs of the user.
