India's Historical Geodetic Standard: Datum 1975
Indian Datum 1975 represents India's historical geodetic reference framework established in the mid-1970s, serving as the primary coordinate system for surveying, mapping, and national infrastructure development across the Indian subcontinent until the adoption of modern reference systems.
Established in 1975 based on extensive geodetic surveys conducted across India, this datum was created to provide a unified national reference system for mapping and surveying applications throughout the country, serving as India's primary geodetic framework for several decades.
Indian 1975 served as the official coordinate reference for national mapping projects, infrastructure development, land surveying, cadastral mapping, and governmental spatial data applications across India during the late 20th century, forming the foundation for numerous historical geographical datasets.

With accurate 7-parameter values, Indian 1975 to WGS84 conversion typically achieves 1-10 meter accuracy, suitable for integrating historical Indian data with modern applications. The actual accuracy depends on the precision of the input parameters, quality of original coordinates, specific geographical location within India, and the age and characteristics of the original Indian 1975 data.
For applications requiring higher precision, consider supplementing the transformation with additional local corrections or conducting field verification of transformed coordinates against modern control points.
Due to India's vast geographical extent and diverse topography, optimal transformation results may require region-specific 7-parameter sets. While general parameters provide reasonable accuracy across most of India, highest precision applications may benefit from parameters optimized for specific states, regions, or project areas within the country.
