mpas_analysis.shared.grid.ProjectionGridDescriptor

class mpas_analysis.shared.grid.ProjectionGridDescriptor(projection)

A class for describing a general logically rectangular grid that can be defined by a pyproj projection.

__init__(self, projection)

Constructor stores the projection

Parameters

projectionpyproj.Proj object

The projection used to map from grid x-y space to latitude and longitude

Methods

__init__(self, projection)	Constructor stores the projection
create(projection, x, y, meshName)	Given x and y coordinates defining the axes of the logically rectangular grid, save the coordinates interpolate/extrapolate to locate corners.
project_to_lat_lon(self, X, Y)	Given X and Y locations of points in a projection, returns the corresponding latitude and longitude of each point.
read(projection, fileName[, meshName, …])	Given a grid file with x and y coordinates defining the axes of the logically rectangular grid, read in the x and y coordinates and interpolate/extrapolate to locate corners.
to_scrip(self, scripFileName)	Create a SCRIP file based on the grid and projection.
