Majibu na maelezo huonekana unapojibu maswali.

  1. What can AI help analysts do with large collections of satellite images?
    • Find patterns and changes across imagery for human interpretation
    • Replace all field observations with certain diagnoses
    • Guarantee that every land-cover label is correct
    • Create satellite observations where no sensor data exist
  2. Je, 'ugunduzi wa mabadiliko' hufanya nini katika uchanganuzi wa setilaiti?
    • Huhesabu satelaiti katika obiti
    • Inalinganisha picha za mahali pamoja kwa muda ili kuripoti tofauti muhimu
    • Inabadilisha rangi ya satelaiti
    • Hugundua satelaiti mpya zinazozinduliwa
  3. Kwa nini rada ya aperture ya syntetisk (SAR) ni muhimu sana?
    • Inafanya kazi tu siku za jua
    • Inachukua picha za rangi kwa watalii
    • Inaweza kuona kupitia mawingu na kufanya kazi usiku
    • Inachukua nafasi ya hitaji la AI yoyote
  4. What does the USGS describe NDVI as measuring?
    • A complete diagnosis of plant health
    • The amount of rainfall in a watershed
    • The concentration of minerals in soil
    • The contrast between near-infrared and red reflectance used as a vegetation index
  5. 'Semantic segmentation' ni nini katika uchanganuzi wa picha?
    • Kuweka lebo kila pikseli kulingana na darasa lake, kama vile maji, barabara au msitu
    • Inafuta sehemu za picha
    • Kufinyiza picha kwa faili ndogo
    • Kutafsiri manukuu ya picha katika lugha zingine
  6. What PlanetScope coverage did Planet document for its Dove fleet?
    • Continuous video of every location
    • Near-daily multispectral coverage over landmasses
    • Daily imagery of every ocean depth
    • A guaranteed clear image of every land parcel each day
  7. Why are large satellite scenes often divided into smaller image tiles before model processing?
    • It turns radar data into visible-light photographs
    • It guarantees every tile shows a different land-cover class
    • Tiling makes a very large scene manageable for computation and localized analysis
    • It removes the need to align images from different dates
  8. What can combining multiple spectral or radar bands help an analyst infer beyond visible color?
    • The exact identity of every person on the ground
    • The satellite's remaining fuel
    • A guaranteed forecast of next year's weather
    • Properties such as vegetation condition, soil moisture, or flooding
