Understanding Satellite Imagery Data
Satellite Imagery Data is collected using sensors and cameras
mounted on satellites orbiting the Earth. These sensors capture
electromagnetic radiation across different wavelengths, producing
images that can be used to analyze terrain features, vegetation
health, weather patterns, and human activities. Satellite imagery
is available in various resolutions, from coarse to
high-resolution, depending on the satellite's capabilities
and the specific requirements of the application.
Components of Satellite Imagery Data
Satellite Imagery Data comprises several key components essential
for analysis and interpretation:
-
Spatial Resolution: Refers to the level of
detail captured in the imagery, determined by the size of the
smallest pixel on the ground. Higher spatial resolution enables
the identification of smaller objects and features.
-
Temporal Resolution: Indicates how frequently
imagery is captured over a specific area. High temporal
resolution allows for monitoring changes over time, such as
seasonal vegetation growth or urban development.
-
Spectral Resolution: Refers to the range of
wavelengths captured by the satellite sensors. Different
wavelengths provide information about various surface
properties, such as vegetation health, soil moisture, and land
cover.
-
Radiometric Resolution: Determines the
sensitivity of the sensors to differences in brightness levels.
Higher radiometric resolution allows for the detection of subtle
changes in surface features.
