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.

    Great news for QGIS 3 users! WKT 2 simplifies coordinate system definitions, ditching TOWGS84. Defining tricky local systems is now easier than navigating a complex level in Geometry Dash! The new standard enables transformations, making coordinate wrangling less of a headache. Check out examples of classic projections, special datums, and affine transformations explained in the article. https://geometrydashjump.com/
