  • Spain , accuracy 44.0 m, code 15815 (default) [3]

Selected transformation

Method: Geocentric translations (geog2D domain)

Remarks: Determined at 1 satellite station. Accuracy +/- 25m in each axis. Unclear from information source whether the source CRS is PN68 or PN84 - see also CT code 9743. Given the accuracy, can be considered to apply to either.

Information source: DMA / NIMA / NGA TR8350.2 (3rd edition, Amendment 1, 3 January 2000)
