Местные системы координат в WKT 2

ErnieBoyd, 15.10.2020

В QGIS 3 стандартом описания систем координат стал формат WKT 2. Важное отличие от прежнего стандарта PROJ4 — возможность использования преобразований. Стал ненужным элемент TOWGS84 и исчезли затруднения с определением городских систем координат.

В статье приводятся примеры представления различных местных систем координат в формате WKT:

  • классическая проекция;
  • проекция на особом датуме;
  • проекция с дополнительным аффинным преобразованием.
