%description
Methods for anonymisation of spatial datasets while preserving spatial
structure and relationships. Original coordinates or raster geometries are
transformed using randomized or predefined vertical shifts, horizontal
shifts, and rotations. Compatible with point-based data in 'matrix',
'data.frame', or 'sf' formats, as well as 'terra' raster objects. Supports
reversible anonymisation workflows, hash-based validation, shapefile
export, and consistent tangling across related datasets using stored
transformation sequences. Approach informed by the De-Identification
Decision Making Framework (CM O’Keefe, S Otorepec, M Elliot, E Mackey, and
K O’Hara 2017) <doi:10.4225/08/59c169433efd4>.
