- A cartographer uses satellite imagery with a resolution of 0.5 meters per pixel to map a forested region. A drone survey covers an area of 2.4 km², and each image tile covers 1600 pixels. How many image tiles are needed to fully map the region?
- Area in square meters: 2.4 km² = 2.4 × 1,000,000 = <<2.4*1000000=2400000>>2,400,000 m².
- Number of tiles: 9,600,000 ÷ 1600 = <<9600000/1600=6000>>6000 tiles.
