{"name": "Hatt2GreekGrid", "package_name": "hatt2greekgrid", "description": "Georeference scanned Hatt-projection topographic diagrams and maps (small or large sheets) and transform them to the current Greek Grid / GGRS87 (EPSG:2100). Users add control points on an embedded Georeferencer-style UI canvas, define the map sheet by name or geographic coordinate centre (\u03c6, \u03bb), and export a world-file-ready TIFF or JPEG.", "about": "Hatt2GreekGrid converts topographic diagrams or maps referring to the Hatt azimuthal-equidistant projection (old Bessel datum) to the Greek Grid (EPSG:2100). It supports the small-to-large sheet centre change and former-to-new Bessel Helmert step, then applies the official OKXE per-sheet polynomials (or an analytic PROJ path) with live per-point and total RMS.", "homepage": "https://github.com/schakidou/hatt2greekgrid", "repository": "https://github.com/schakidou/hatt2greekgrid", "tracker": "https://github.com/schakidou/hatt2greekgrid/issues", "author": "Assist.
