geodesy-wgs84-knowledge-patch

What problem does it solve?

This knowledge patch prevents incorrect or outdated coordinate transformations by providing authoritative formulas, PROJ pipeline patterns, Helmert conventions, and pyproj usage so developers and analysts avoid runtime errors and subtle geodetic inaccuracies.

Core Features & Use Cases

• Accurate coordinate conversions: ECEF ↔ geodetic (Olson's closed-form), and ECEF ↔ ENU/NED rotation matrices with edge-case handling.
• PROJ and Helmert guidance: Pipeline construction, Helmert conventions including 7- and 14-parameter kinematic transforms, and topocentric examples.
• pyproj patterns: UTM zone lookup, 3D CRS promotion, TransformerGroup inspection, 4D epoch transforms, and geodesic computations for GIS integrations.
• Use case: Convert satellite or survey ECEF positions to lat/lon/height, construct datum-shift pipelines, and integrate with pyproj for high-precision mapping and analysis.

Quick Start

Use the geodesy-wgs84-knowledge-patch to convert ECEF coordinates to latitude, longitude, and ellipsoidal height and to build a PROJ pipeline for the required datum shift.
