salem.DatasetAccessor.roi¶
- DatasetAccessor.roi(self, shape=None, geometry=None, grid=None, corners=None, crs=wgs84, roi=None)¶
Make a region of interest (ROI) for the dataset.
All grid points outside the ROI will be masked out.
Parameters: shape : str
path to a shapefile
geometry : geometry
a shapely geometry (don’t forget the crs keyword)
grid : Grid
a Grid object which extent will form the ROI
corners : tuple
a ((x0, y0), (x1, y1)) tuple of the corners of the square to subset the dataset to (don’t forget the crs keyword)
crs : crs, default wgs84
coordinate reference system of the geometry and corners
roi : ndarray
if you have a mask ready, you can give it here
