salem.Grid.transform¶
-
Grid.
transform
(x, y, z=None, crs=<pyproj.Proj object>, nearest=False, maskout=False)[source]¶ 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.
