Remote Sensing Principles starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Remote Sensing Principles.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11

Remote sensing involves the detection and measurement of radiation of different wavelengths reflected or emitted from distant objects or materials. True or False?
The electromagnetic spectrum is important in remote sensing because different materials reflect and absorb different wavelengths. True or False?
True or False: Hyperspectral sensors collect data in hundreds of narrow spectral bands.
True or False: Multispectral sensors can detect energy in multiple bands of the electromagnetic spectrum.
