About this technology
Overview
simplegrid is a python package for creating, refining, and joining horizontal quadrilateral grids that are used in connection with the MIT General Circulation Model (MITgcm).simplegrid is based on equal great circle arc subdivision (hence the name) with geodesic computations provided by pyproj/PROJ.4, and implements both python-callable and command-line functionality for embedded and scripted solutions. It also contains several useful utilities for grid manipulation, file i/o, and coincident edge detection.
