salem.Grid.region_of_interest¶
- Grid.region_of_interest(shape=None, geometry=None, grid=None, corners=None, crs=<pyproj.Proj object at 0x7f02c81c1a10>, roi=None)¶
Computes a region of interest (ROI).
A ROI is simply a mask of the same size as the grid.
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
add the new region_of_interest to a previous one (useful for multiple geometries for example)
