3
Q
Radiometric Preprocessing
A
- influences the brightness values of an image to correct for sensor malfunctions
- adjusts values to compensate for atmospheric degradation
- Removes clouds
4
Q
Data Fusion
A
- Combines Panchromatic (spatial) with spectral bands
- Two images w/varying resolution into a single image for visualization
- Increases spatial/spectral properties
5
Q
Principal Component Analysis
A
- Lessens amount of data for classifications
2. Consolidates the maximum variation
6
Q
Remote Sensing applications of PCA’s
A
- Data reduction
- Noise removal
- classification, detection, time series analysis
