Thiruarankundram Deepathoon vs The Survey stone claim Propaganda

Yes, there are two hill-station survey points, and their spatial relationship precisely corresponds to the station characteristics documented in

“THE GREAT TRIG: Principal and Secondary Stations – The Great Arc, Section 8° to 18°, Series A of Trigon.”

While the recovery of exact historical coordinates today can be challenging due to datum shifts, terrain modification, and limitations of modern geospatial overlays, the textual descriptions, relative bearings, distances, and alignment with the fundamental latitude–longitude grid framework remain invariant.

These parameters are governed by classical geodetic principles and therefore cannot be invalidated or contradicted by minor positional discrepancies observed in contemporary mapping platforms or 3D visualizations.

Any challenge to this conclusion must present scientifically valid counter-evidence that directly addresses these stable descriptive, directional, and geometric constraints, rather than relying on visual approximation alone.

Survey Record Descriptions (Great Arc – Meridional Series, Section 8° to 18°)

1. No. 1 H.S. (Principal Hill Station)

> “On an isolated rocky hill about 550 to 600 feet high, and on the high road from Madura to Sivagangai, at the east end of a large tank, about a mile north of the village of Nelaiyur, 4½ miles south-west of Madura, and 6½ miles north-east of the town of Tirumangalam; taluk Madura.

The station is marked by a circle and dot engraved on the rock in situ, towards the north-west side of the summit, and about 50 yards N.N.W. of the mosque on the top of the hill.

1871.”

2. No. 2 H.S. (Secondary Hill Station)

> “On a well-known rocky hill, about 53 yards S.S.E. of Sikandarmalai No. 1 H.S.; taluk Madura.

The station is marked nearly in the centre of the platform of the mosque on the summit of the hill.

1808–09.”

The N.N.W.–S.S.E. alignment, relative distances, and station hierarchy (Principal and Secondary) described above establish a clear, internally consistent geodetic relationship, fully compatible with the Great Trigonometrical Survey methodology.
