Question 4
Write the characteristics of satellite images.
Answer
The characteristics of satellite images are:
- Spatial resolution: It refers to the level of detail that a satellite image can provide. The higher the spatial resolution, the more detailed the image will be.
- Spectral resolution: It refers to the range of colors or wavelengths that a satellite sensor can detect. The more bands a sensor has, the better its spectral resolution.
- Temporal resolution: It refers to the frequency at which a satellite passes over a particular area. The higher the temporal resolution, the more frequently the area can be imaged.
- Radiometric resolution: It refers to the ability of a satellite sensor to distinguish between different levels of brightness or reflectance in an image.
- Geometric accuracy: It refers to the degree to which a satellite image accurately represents the position and shape of features on the Earth’s surface.
