Python for Cadastral & High-Precision Coordinate Transformation
Authoritative, production-grade Python implementations for cadastral coordinate transformations, grid shifts, and survey-grade validation — bridging rigorous geodetic theory with deployable, audit-ready code.
From parsing NTv2 .gsb grids byte-for-byte to running least-squares control-network adjustments, every workflow here is engineered for sub-centimetre tolerances, ISO 19111 metadata compliance, and reproducible audit trails. The code is type-hinted, precision-controlled, and ready to drop into production transformation pipelines.
Two deep reference clusters anchor the site: the fundamentals and standards that govern legally defensible transformations, and the algorithmic math and geodetic workflows that turn geodetic theory into deterministic solvers. Pick a starting point below.
