CISCE: Class 10
Key Points: National Grid Reference
- Survey of India (SOI) introduced the Open Series Maps under the National Map Policy, 2005, using the International Map of the World (IMW) numbering system.
- In the IMW system, India’s map numbers begin without the letter ‘N’ (as India lies in the Northern Hemisphere) and are based on 6° × 4° grid regions.
- Each 6° × 4° region is divided into 24 squares of 1° × 1°, identified by alphabets (A onwards), and further divided into 16 smaller squares of 15′ × 15′ marked by numbers.
- Eastings are vertical lines running north–south, increase eastwards, and are always written first in grid references.
- Northings are horizontal lines running east–west, increase northwards, and are written after Eastings to locate a place accurately.
