Which of the following image consist of highest forest area? 3500 forest pixels from ASTER Image at 15m * 15m spatial resolution 2000 forest pixels from Landsat 5 TM at 30m * 30m spatial resolution 30 forest pixels from MODIS image at 250m * 250m spatial resolution 5 forest pixels from MODIS image at 500m * 500m spatial resolution

Step 1
ASTER: $3500 \text{ pixels} \times (15m \times 15m) = 3500 \times 225 m^2 = 787500 m^2$ Landsat 5 TM: $2000 \text{ pixels} \times (30m \times 30m) = 2000 \times 900 m^2 = 1800000 m^2$ MODIS (250m): $30 \text{ pixels} \times (250m \times 250m) = 30 \times 62500 m^2 Show more…
