pyremap.descriptor.ProjectionGridDescriptor¶

class pyremap.descriptor.ProjectionGridDescriptor(projection)[source]¶

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

__init__(projection)[source]¶

Constructor stores the projection

Parameters: projection (pyproj.Proj object) – The projection used to map from grid x-y space to latitude and longitude

Methods

`__init__`(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`(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_esmf`(esmfFileName)	Create an ESMF mesh file for the mesh
`to_scrip`(scripFileName)	Create a SCRIP file based on the grid and projection.
