Explanation

In the Survey of India topographic map numbering system, the 1:1,000,000 scale is represented by a number (e.g., 47). The 1:250,000 scale adds a letter (47A). The 1:50,000 scale adds a number (47A/16). The 1:25,000 scale adds a quadrant designation (NW, NE, SW, SE). Therefore, 47A/16/NW corresponds to 1:25,000.
