ECDOview — Ancient Site Alignment Verification Tool
About ECDOview
ECDOview is a free, interactive web application for verifying ancient monument alignments to the hypothesized State 2 North Pole position (NP') proposed by ECDO Theory (Exothermic Core-Mantle Decoupling — Dzhanibekov Oscillation). The tool allows researchers and enthusiasts to measure the orientation axis of any structure visible on satellite imagery and test whether its great-circle extension passes through NP' at 14°S, 31°E in southern Zambia.
ECDO Theory Overview
ECDO Theory, developed by The Ethical Skeptic over 25 years of independent research and first published in February 2020, proposes that the Earth periodically undergoes dramatic True Polar Wander events. The theory posits two stable rotational states: State 1 (current), where the geographic north pole is at 90°N, and State 2, where the pole shifts approximately 104° along the 31°E meridian to 14°S, 31°E. Over 200 ancient monuments worldwide exhibit alignments consistent with this hypothesized pole position, including the Great Pyramid of Giza, Nazca Lines, Sacsayhuamán, Göbekli Tepe, Gunung Padang, Ġgantija Temples, Puma Punku, Newgrange, The Flagstones, and Mount Pleasant Henge.
Key Features
- Measure Alignment: Click two points on any structure to compute the great-circle bearing and test alignment to NP'
- Bearing Deviation Analysis: Angular difference between measured axis and direct bearing to NP' (0° = perfect alignment)
- Reverse Bearing Check: Automatically tests both directions and uses whichever is closer to NP'
- State 1 Visualization: Current equator, tropics, geographic and magnetic north/south poles with source links to NOAA and NCEI
- State 2 Visualization: ECDO hypothesized equator, tropics, and arctic circles based on NP' at 14°S, 31°E
- 69 Reference Sites: Pre-loaded ancient sites across 6 regions with info cards showing construction period, builders, coordinates, and ECDO relevance
- 3D Globe: Interactive Three.js globe with all measurements, poles, and State lines rendered in 3D
- Inundation Overlay: Adjustable sea-level visualization based on ECDO-predicted 175m (576 ft) oceanic displacement height
- Measurement Log: Persistent localStorage history with naming, per-measurement copy, and full clipboard export
- Screenshot Export: Capture current map view as PNG with watermark
- Google Maps and ESRI satellite tile providers with up to zoom level 22
- Mobile responsive design

Technical Details
ECDOview uses geodesic mathematics including Haversine distance, initial bearing calculation, destination point formulas, cross-track distance, and small circle generation for climate zone visualization. All computations run client-side with no server backend. The tool is built with Leaflet.js for 2D mapping, Three.js for 3D globe rendering, and uses ESRI World Imagery and Google Maps satellite tiles.
