salem.Grid.transform¶
- Grid.transform(x, y, z=None, crs=<pyproj.Proj object at 0x7f02c81c1a10>, nearest=False, maskout=False)¶
Converts any coordinates into the local grid.
Parameters: x : ndarray
the grid coordinates of the point(s) you want to convert
y : ndarray
the grid coordinates of the point(s) you want to convert
z : None
ignored (but necessary since some shapes have a z dimension)
crs : crs
reference system of x, y. Could be a pyproj.Proj instance or a Grid instance. In the latter case (x, y) are actually (i, j). (Default: lonlat in wgs84).
nearest : bool
set to True if you wish to return the closest i, j coordinates instead of subpixel coords.
maskout : bool
set to true if you want to mask out the transformed coordinates that are not within the grid.
Returns: (i, j) coordinates of the points in the local grid.
