Which method is used to digitize large volumes of text efficiently?

  1. GIS
  2. OCR ✓
  3. 3D scanning
  4. Bit mapping

Explanation

OCR stands for Optical Character Recognition. It converts scanned images and photos of text into editable documents. Instead of retyping pages manually, OCR does it automatically.

GIS maps geographic data like cities and roads. 3D scanning captures object shapes. Bit mapping stores images as pixels.

Libraries use OCR to digitize old books and documents. This technology saves countless hours of typing work.
