13.10.2. Radiometric Errors

Try these first

1. 1.

   What are radiometric errors?

   Hint

   Think about how the pixel brightness can vary.

2. 2.

   Name one source of radiometric error.

   Hint

   Consider what might interfere with the sensor's readings.

3. 3.

   What causes radiometric errors?

   • Sensor noise
   • Incorrect GPS data
   • Inconsistent reference targets

   Hint

   Think about what types of issues could affect the sensors.

4. 4.

   True or False: Radiometric normalization is used to standardize brightness levels in images.

   • True
   • False

   Hint

   Consider how different images might need adjustments for comparison.

5. 5.

   Consider a scenario where a satellite image taken at different times shows significant variations in pixel brightness for a specific area. Explain how radiometric normalization could help in analyzing this data.

   Hint

   Think of how consistent brightness aids in fair comparisons.

6. 6.

   You are tasked with analyzing land use changes over time with satellite imagery affected by varying atmospheric conditions. Describe the approach you would take to account for these effects in your analysis.

   Hint

   Consider what models specifically address atmospheric interferences.
