Cartographic representation of data in the National Atlas of India

Summary

This paper examines the cartographic methods used to represent socio-economic data in the National Atlas of India, specifically focusing on thematic maps at a scale of 1:6 million. It covers various aspects including agriculture, industry, commerce, finance, and social conditions. The study details multiple cartographic techniques such as dot methods, proportional circles, proportional squares, sector diagrams, semi-circles, and pictorial symbols, analyzing the suitability and limitations of each approach in different data contexts. The findings highlight that data collection and processing are critical stages in map compilation, and that symbol selection must balance information accuracy, map legibility, and visual appeal. This research provides practical insights for the production of large-scale thematic atlases.
