pyremap.descriptor.ProjectionGridDescriptor.read

classmethod ProjectionGridDescriptor.read(projection, fileName, meshName=None, xVarName='x', yVarName='y')[source]

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.

Parameters:

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

  • fileName (str) – The path of the file containing the grid data

  • meshName (str, optional) – The name of the grid (e.g. '10km_Antarctic_stereo'). If not provided, the data set in fileName must have a global attribute meshName that will be used instead.

  • xVarName (str, optional) – The name of the x and y (in meters) variables in the grid file

  • yVarName (str, optional) – The name of the x and y (in meters) variables in the grid file
