Step 1: Understanding Digital Photogrammetry Workstations.
A Digital Photogrammetry Workstation (DPW) is a computer-based system designed for processing and analyzing aerial and satellite images.
Step 2: Evaluating the given statements.
- Statement i: DPWs handle very large image files – Correct.
- Statement ii: DPWs perform computationally intensive tasks such as DEM generation and ortho-rectification – Correct.
- Statement iii: DPWs allow smooth navigation and zooming in high-resolution imagery – Correct.
- Statement iv: Scanning facility is not a core function of DPWs; scanning is generally done by separate devices before processing – Incorrect.
Step 3: Selecting the correct option.
Since statements i, ii, and iii are relevant, the correct answer is c. i, ii and iii.
